130/135/160/200mm Carbon Mini Quadcopter frames
130/135/160/200mm Carbon Mini Quadcopter frames
Here are some 160mm Mini Quadcopterframes I have designed. See the pictures below. I plan to build with the flowing components.
Kiss 12A ESC's
Sunnysky X1306S 3100KV brushless motors
HQ 4x4.5 bullnose propellers
AlienWii32 brushless FC (Naze32 and clones with 30mm mounting holes will also fit)
LemonRX DSMX satellite
Mylipo 850mAh 3S 45/90C batteries
Pololu 5V regulator as BEC
Piezo buzzer
Frames and arms are 3mm and center-/topplates are 1mm carbon. Looking forward to finalize them now. Most other 1306 motors should also work.

Re: 160mm Carbon Mini Quadcopter frames
Here are some more pictures during build. Until the AlienWii32 brushed with build in power distribution will arrive I'm using an AcroNaze as FC. The pins are mounted in a way to save space and have a low profile.
Edit: the 3.3V power cable is still connected wrong at the Naze pictures. I was needed to fix this.

Re: 160mm Carbon Mini Quadcopter frames
The 160mm quad (modular frame) had maiden flight a few minutes ago. Everything is working quite well and it looks to have endless power (even the battery looks to be a bit large). Now some more tuning will start. I flashed the brand new released Cleanflight 1.9.0 to the AcroNaze. The weight is 222g including the Battery (82g)

Re: 160mm Carbon Mini Quadcopter frames
Hi new to this I just stopped to admire your quad very nice~! Did you cut the frames?
Re: 160mm Carbon Mini Quadcopter frames
I designed this frames but don't cut them by my self. I have someone who is doing professional carbon cutting where I order them. For now this was an test run in prototype stage but the result worked out quite well. The frame already survived an major crash without an scratch. I wanted an small fast brushless quadcopter. You can find my small brushed multicopters in the other thread:

Re: 160mm Carbon Mini Quadcopter frames
I now finished my second 160mm MiniQuad build with the single piece frame:
Single piece 160mm carbon frame
Kiss 12A ESC's
DYS BX1306 3100KV brushless motors
HQ 4x4.5 bullnose propellers
AcroNaze (16MByte SPI flash)
LemonRX DSMX satellite
Turnigy Nano-Tech 850mAh 3S 45/90C batteries
Piezo buzzer
The video is just uploading;
http://youtu.be/5nlporNuqCo
Here are the related settings using the Cleanflight 1.9 developer build with the new filters:
The DYS motors are 1.5g more heavy per motor than the SunnySky so finally even without having an Pololu this build is only 4g lighter then the modular frame build. Having better maintainability in mind (broken arms can simply be replaced) I would now always go for the modular build.

Re: 200mm Carbon Mini Quadcopter frames
Since it was raining yesterday i finished the first of the tree planned 200mm MiniQuad builds. AUW is 296g including an 1000mAh 3S Nano-Tech battery (92g). Im using the firmware from BorisB's Betafligth fork with gyrosync enabled. All bench tests are completed but the maiden flight is still outstanding. Will see how tuning will go.
Here is the list of the individual components used:
200mm modular frame
Kiss 18A, KISS 12A ESC's
DYS BÉ1806-2300KV motors
HQ 5045 Bullnose propeller
Dodo Flight controller
LemonRX DSMX satellite
3S 1000mAh 45/90C Turnigy Nano-Tech battery
Piezo buzzer
Some pictures will follow if the light conditions are better for shooting them.

Re: 200mm Carbon Mini Quadcopter frames
Here are now the pictures from the new 200mm MiniQuad. The last picture is showing the comparison between the 160mm, 200mm MiniQuad and the WarpQuad. I think i also have a name for the frames now. "SimpleQ" since the design is very simple but efficient and robust. I crashed the 160mm quite a couple of times without any frame damage (ok, some minor scratches since i crashed on concrete ). I did the maiden flight this morning and my initial tuning values fit already very well. I'm running the very latest Betafligth firmware from BorisB's test fork. I started testing with PID1 (profile2, my well known tunes from the 160mm) and moved to PID2 (profile1, new tunes derived from BorisB settings). I likely will stay with the profile1 settings. Flight time was always between 5:30 and 6:00 minutes with the 3S 1000mAh 45/90 Turnigny Nano-Tech batteries and I was going high speed most of the time. Here are my settings:

Re: 200mm Carbon Mini Quadcopter frames
Finished the second 200mm build with Sunnysky X1806S KV2300 motors yesterday. I hove no new pictures since they would be very similar to the initial build. I was planning to make some pictures during building but light condition are not really good to take them during the dark . Upgraded to the latest Betaflight and they are flying very well. Here are my actual settings after some more tuning:
Actually I like flying profile0 (Luxfloat PID) most. With this settings the quad is very agile and fast. The horizon mode is very steady and not really for flying since the reaction to stick input is rely wake but I anyhow fly most acro and this mode is really the last possibility to save the gear if I will be able to switch fast enough while loosing orientation. But profile1 (PID rewrite) is also flying quite well.
Now the single frame build with the Sunnysky x1306 KV3100 motors is still pending I plan to use an Naze32 Acro as FC for this.

Re: 200mm Carbon Mini Quadcopter frames
Some more 200mm modular frames are arrived. If there is interest I can put some kits on e-bay. The kit will contain an crash kit (some additional spare parts). Here is what I have in mind:
2 x center plates 1,5mm carbon
1 x top plate 1mm carbon
4+2 x arms 3mm carbon
4+2 x 12mm black hex nylon standoffs
4+2 x 6mm black hex nylon standoffs
4+2 x 10mm M3 torx stainless screws
4+2 x 12mm M3 torx stainless screws
16+4 x 6mm M2 torx stainless screws
8+2 x M3 stainless look nuts
8+2 x 3mm black O-Rings
1 x 16mm Velcro battery strap
1 x 5mm self adhesive strip (battery padding)
The price will end up around 80€ including shipping to Germany (additional 5€ for international shipping). let me know if there is some interest.

Re: 160mm Carbon Mini Quadcopter frames
I started to move to LemonRX diversity satellites. Sometimes I had reception issues with normal LemonRx satellites wich even caused crashing. Here is an picture how I mounted this. I used zip tie and heat shrink. Likely in my next build I also will cover the whole areal with some thin heat shrink till the end of the Antenna in addition to make it more stable.
Re: 200mm Carbon Mini Quadcopter frames
Last days I finally finished the Quadcopter build with the 200mm single piece frame and 1306 motors.
KISS 12A ESC's
Sunnysky x1306 KV3100
HQ 5040 Propeller
ACRO Naze32 Rev 5
LemonRX DSMX diversity satellite
3S 1000mAh batteries 45/90C
Piezo buzzer
Im running an Betaflight version from October 25th. Here are the actual settings:
The quad feels more agile then its brothers with 1806 motors and BN propellers. Looks to be the lighter motors and propellers are more responsive. With racing the two back motors get only a light touch of temperature and the front motors stay completely cool. The diversity antenna's of the LemonRX receiver are very fragile and I modified the mounting. The antennas will rip out of the connector with very little force. With my initial mounting this could happen during bending the zip tie during battery change or during light crashing. See pictures from initial mounting in my previous post here. I now open the RX and cover the whole antenna with 1mm heat shrink including the first part of the connector. After mounting them again I will take care bending the antenna will not put any force to the antenna itself. I will leave a little sloop at the bottom. Please see also the pictures below.
BTW: All my 1806 SunnySky motors are fakes and I returned them to the sellers. I replaced them with DYS 1806 motors. They are a bit more heavy but are more robust during crashing. The 1306 SunnySky motors are very light and nice build but not very crash resistant. DYS 1306 are also more robust.

The quad feels more agile then its brothers with 1806 motors and BN propellers. Looks to be the lighter motors and propellers are more responsive. With racing the two back motors get only a light touch of temperature and the front motors stay completely cool. The diversity antenna's of the LemonRX receiver are very fragile and I modified the mounting. The antennas will rip out of the connector with very little force. With my initial mounting this could happen during bending the zip tie during battery change or during light crashing. See pictures from initial mounting in my previous post here. I now open the RX and cover the whole antenna with 1mm heat shrink including the first part of the connector. After mounting them again I will take care bending the antenna will not put any force to the antenna itself. I will leave a little sloop at the bottom. Please see also the pictures below.
BTW: All my 1806 SunnySky motors are fakes and I returned them to the sellers. I replaced them with DYS 1806 motors. They are a bit more heavy but are more robust during crashing. The 1306 SunnySky motors are very light and nice build but not very crash resistant. DYS 1306 are also more robust.

Re: 130mm Carbon Mini Quadcopter frames
Here are the settings is have successfully used today:
This morning after proper maiden flight in my living room i replaced an propeller since it had some damage from testing. I tock the picture with an wrong propeller and found this out today during trying some outside flying. I should not do things like this at 3:00 in the morning.
It is flying very well with the 2S battery but the flight time is quite short 2.5 to 3.5 minutes before the voltage alarms starting to kick in. I have some 3S batteries on order.
The weight without battery is 72g. The 2S battery is 32g.

Re: 160mm Carbon Mini Quadcopter frames
mj666: These are some very nice mini/micro brushless frames! I like the 160 and 130 in particular. Good to hear the 130 flies well, even with "only" 4000KV and 2S LiPo. I think people get carried away with high-KV and high voltage these days.
It will be nice when the Alien Brushless FC becomes available, as it seems ideal for builds of this scale! I'm also curious to see how it will compare in weight to a 30x30 FC plus 4-in-1 ESC (versus Alien BL + 4x KISS ESC). There seem to be significant weight savings in thinner gauge wiring in your build, almost like on a brushed micro.

Re: 130mm Carbon Mini Quadcopter frames
There is 10g difference between the last two builds (130mm brushless). During flight I don't feel a real difference. Likely the thicker gauge wires (22 vs. 26 AWG) in the Naze build will give more power to the motors. With 3S the go really fast (likely more than 50-60km/h). We don't had good experiance with standard BLHELI ESC's and the high KV motors. Kiss was working the best for now. May be Silabs 39x ESC's or BLHELI_S will work better.

Re: 200mm Carbon Mini Quadcopter frames
New version of the 200mm compact frame. 1306 and 1806 motors can be mounted now. The root of the arms is a bit stronger and I omitted the second hole for the larger center plate.

Re: 130mm/135mm Carbon Mini Quadcopter frames
The new 130 and 135mm brushed Frames are arrived. See some pictures below. I put a few kits on eBay today. These kits always contain the frame (2.5mm carbon), the top plate with AlienFlight graving (1mm carbon) und 5 2x12mm Nylon standoffs and 10 M2 Nylon screws. There are two variants of the top plate available. By default, the kit comes with the smaller variant. The frames has mounting holes for a flight controller with 20x20mm distance and the 135mm frame as mounting holes with 30.5x30.5mm distance in addition. The distance of the motor mounting holes will fit for various micro motors (DYS BE1104, RCx H1105, RCX H1304). The 110mm brushless frame will follow the next days.

Re: 160mm Carbon Mini Quadcopter frames
Nice work, mj666! The new 135mm frame with 20x20 and 30.5x30.5 mounting holes looks perfect (and of course the Alien Flight BL FC too).
Re: 135mm Carbon Mini Quadcopter frames
Last days I finished an new build using the new 135mm frame. I have used the flowing components:

Re: 130mm Carbon Mini Quadcopter frames
Last days i was working on an new 130mm Quadcopter with the Piko BLX FC. This has 20x20 mounting pattern and an intergrated PDB. It is an perfect fit for an miniquad and makes building a bit more easy.

Re: 135mm Carbon Mini Quadcopter frames
Today I had an new maiden flight with the BlueJayF4 based 135mm build. I was running an Betaflight 3.0 custom build from the development branch. I had 4 flights without any issue. At the moment the startup of the BlueJay is an bit tricky but after this its running flawless. This problems likely will be fixed in one of the next builds. Here are the setting I have used:

Re: 160mm Carbon Mini Quadcopter frames
mj666: Good to hear you were able to maiden both your 130 and 135mm builds! Did you run both on 2S? Or did you try some 3S LiPo as well? How was the performance? How was the flight time? It would be helpful to hear your observations about 1105 5000KV versus 1304 4000KV motors. Video would be cherry on the cake.
Re: 160mm Carbon Mini Quadcopter frames
I run the 135mm build with 2S and 3S. With 2S i often fly with maximum trottle. This will be good for indoor flying. With 3S this is really an angry beast. With the actual rates its super agile.
The 130mm with the RCX H1105 Motors and 5000KV i only used with 3S yet. Ist also going quite well and a bit more more fast as the builds with DYS BE1104 4000KV motors. But i guess this is expectd. The later build i also used with 2S and 3S. Similar like the 135mm build in the free space i often fly with max trotle with 2S.
In genreral all this builds perform quite well with some performance differences. They are all good for indor with 2S (may be not the 135mm build).

Re: 160mm Carbon Mini Quadcopter frames
Hoping finally to build my 135mm frame later this month. I have decided to use 1304 4000KV motors and HQ3030 props. Hopefully, it will fly OK with a 2S 500mAh LiPo. I also have 3S 450mAh for more power outside.
What I still need to decide is FC and ESC. I will probably use a Moto Lab FC (Tornado or Cyclone) and 4-in-1 ESC, since I have those already. However, I am also considering the Piko BLX, which I would then pair with some KISS ESC. In either case, it should be a lightweight yet powerful micro brushless quad.

Re: 160mm Carbon Mini Quadcopter frames
All this options sounds good and from my experiance with different builds should work quite well.
Re: 160mm Carbon Mini Quadcopter frames
Finished another Piko BLX build last days. 130mm frame with FTV Little Bee 20A-S (BLHELI_S) and RCX1105 4000KV motors. Everting else is the same as my previous Piko BLX build. This is also going quite well the BLHELI_S ESC are performing similar to the Kiss (super smooth). I only upgraded them to the latest firmware (16.2) and kept all the default settings (except adjusting the motor directions). I used the 4wire connection of the Piko BLX for flashing with the BLHELI suite. This worked perfectly. No new picture since in principle all is similar to my previous build.
Next days I also planning another new build like this one (same ESC's) but with RCX1304 4000KV motors.

Re: 135 Carbon Mini Quadcopter frames
Last days I finally finished the long announce 135mm build with the H1304 motors. I used the last weeks with very nice weather here mostly for flying than building.
Here are the technical specifications of this build:
135mm Carbon Quadcopter Frame
Piko BLX Fligtht controller
RCX H1304 4000 KV Motors
HQ 3x3 Props
FTV Little Bee 20A BLHeli_S ESC's Multishot
LemonRX DSMX satellite
450mAh 65-130C 3S Nano Tech batteries
Piezo Buzzer
Im using BetaFlight 3.0.0 and BLHeli 16.4 firmware. For BLHeli im using default settings and only changed motor direction for 2 ESC's. The Piko BLX is running with 8k/4K synchronized. Here is the complete BetaFlight configuration:
I was already flying quite some batteries with this build during the last days and the tuning is finalized. Below you also can see some pictures of this build. Anyhow in general it does not look much different to other build with my frames.
BTW: I upgraded all my copters now to BetaFlight 3.0.0 and im very satisfied how the at flying. This is the first time I made an change of the firmware for the whole fleet to the same level.

Re: 130/135/160/200mm Carbon Mini Quadcopter frames
Looking good, Michael!
I still have not started with my 135mm frame. But I have reserved a set of 1304 4000KV motors, like the ones you used, plus a Racerstar BLHeli_S 4-in-1 ESC. Hopefully I can complete the build before the weather deteriorates too much. Probably still a couple more weeks -- too much life and not enough flying.

Re: 130/135/160/200mm Carbon Mini Quadcopter frames
Looking forward to see your build finished and flying. The winter is comming fast now and also flying time get quite limited. Usualy I go one hour flying every morning before work if weather permits. Will now focus again on smaller copters for indoor and may be try some FPV.
Re: 135mm Carbon Mini Quadcopter frames
After long silence here is the information of my last two builds. It is an big improvement to my former RCX1304 motor builds in flight performance. I also used stronger wires, XT30 connectors and stronger batteries. The new 135mm frames are also now 3mm thick. Anyhow over the last years i only broke 3 of the 2.5mm thick frames with basically daily flying in summer. Here are the details for this two builds:
AlienFlight 135mm Carbon Quadcopter Frame
Furious PikoF4/AlienFlightNG F7 Brushless Hex Fligtht Controller
RCX H1304 4000 KV Motors
HQ 3x3 Props
Aikon SEFM 20A BLHeli_S ESC's Multishot (16.6)
FrSky XM+/LemonRX DSMX Satellite Receiver
850/650mAh 75C 4S Tatoo Batteries
Piezo Buzzer
Unfortunately I forgot to remove the filter caps from the ESC's before building and dont want to tear them down again. I was not aware my Aicon's are some of the early ones with the caps still installed. This is why i still use multishoot but except you need to calibrate the ESC's it does not have a real negative impact on performance.
Below a few pictures of the build and also the BetaFlight 3.3.0 configuration for the the PikoF4 build:
Except for the different receiver the AlienFlightNG F7 build has the same settings.
I'm in the process to upgrade all my copters to BetaFlight 3.3.0. Actually running an mix of 3.1.x, 3.2.x versions. All my former builds are still actively flying on more or less regular bases and there is no big need for many new builds since i have a big fleet to fly.
