Dont know if you read this yet but a good starting place for that board ! http://fpvcentral.net/wp-content/upload ... -22-12.pdf

chris ables

Those pulsing motors are from vibration in frame ! I have a crius board and found this out first thing ! If you pm me what radio, esc's, and your quad setup -quadx,ect. I can compile v 2.1 for you and all you will have to do is install it ! You will have to download v2.1 and use the v2.1 gui with th...

chris ables

Yes but only good for about 50 feet !

Re: How stable is stable? Unread postby chris ables » Sat Jul 28, 2012 2:27 pm Ok you do know that the LEVEL PID is for the acc and the pitch and roll is the gyro right ?

Ok you do know that the LEVEL PID is for the acc and the pitch and roll is the gyro right ? Also why is your Mag on when you dont even have it checked in the sensor aux switch boxes ? And if your running high kv motors maybe you have bad vibration when motors speed up ! And lastly i dont know what e...

chris ables

Wow ! Thats pretty bad . Could you give us a screenshot of your gui showing all your pid's and settings on it ?

chris ables

My bad i thought you meant they wasn't spinning in right direction !

chris ables

Swap any two of the three motor wires on the motors you want to reverse ! Also you need to caibrate all 4 esc's with transmitter and plugged in the throttle channel with the props off motors so you dont cut yourself!!!

chris ables

If it's just with acc on you need to lower the LEVEL P value ! If thats the one you are lowering raise the D value ! Also you are not running those new hobbywings with the silab's in them are you? If so alot of people are having that wobble of death with them and can't get them to work ! Seen a few ...

chris ables

You did use the bs.hex file when you flashed them didn't you ? You do not use the tgy.hex for those esc's !

chris ables

If your son is a heli pilot im sure you know what gyro gain is ! The P value works just like the gyro gain ! And if you think it's a handfull try lowering the rc rates in the GUI .

chris ables

AMEN on that !! I just recieved a couple of charging adapters with t plugs on end and one of them was soldered backwards ! Like china has gone colorblind !!

chris ables

Well if it was me i would resolder some new power wires on them and do away with those power plugs and solder them too ! Bad connections or bad wires causes resistance problems and that can fry fets ! Worth trying too see , especialy if you have done fried a few ! The one guy on those reviews even s...

chris ables

Read all of these reviews ! http://www.hobbyking.com/hobbyking/stor ... duct=17135 i bet it's the power plug on it !

chris ables

That's great news !

chris ables

Nevertheless too flexible of a prop does not mix with gyro's too good ! Thats like trying to point a 3 foot string at a chalkboard and your arm is the gyro and the string is the prop ! LOL

chris ables

Thanks for that info tovrin , im in SC and didnt know they had gemfans !

chris ables

That sounds right to me too tovrin ! Esc's out of sync ! Thats why i use the servo y connectors to calibrate all at once on rx throttle channel after i set endpoints in gui ! One esc at a time and sometimes they are not perfectly in sync !

chris ables

Maybe the links on this page can help ! http://beagleboard.org/static/BONESRM_latest.pdf i am not familiar with that . Sorry !

chris ables

No problem and yes let me know the outcome ! Also i run the 9x4.7 slow fly not for gas engine prop from apc ! Thats the only 9 inch size they have with pusher available ! If you choose to run the gemfan be sure to get the carbon reinforced one's as they are real lightwieght and stiff props and also ...

chris ables

I used to run those flimsy gaui props and had that wobble of death also ! Changed to a stiffer prop and wobble went away ! When a prop flexes it causes gyro's or acc to kick in because of thrust loss and causes what i call a gyro train ! Those gaui props are only good for slow flying with very light...

chris ables

As far as the acc z it will be in the 250 range and that is correct ! And for the mag calibration you dont shake it you actualy roll it one complete roll then flip it one complete flip then spin it one complete turn ! And be sure the ftdi doesnt disconnect ! I have problems with disconnecting if mov...

chris ables

WOW! Cool ! Looks pretty touchy on flying controls ! I want a full size one i can ride in !

chris ables

Hi, I balanced everything as good as I could. The props are not the source of the vibrations, the motors are creating them. I use new bearings and new shafts but these CF2822 are s**t. But I use to crash very often because I try new s**t every day so it is too early to get new motors . If the LPF h...

chris ables

My acc acts simular to that if i dont calibrate acc with tx sticks ! Do this with motors disarmed ! http://multiwii.googlecode.com/svn/bran ... 721566.pdf this link shows you how ! I have also heard to do this right after flashing firmware and before you use the button in gui to calibrate acc ! So you might want to reflash firmware and try this !

chris ables

viewtopic.php?f=8&t=1427&hilit=400hz+output+file go here and try the 400hz output file ! It only works with version 2.0 !

chris ables

Glad to see my wish for gui - tunable esc refresh rate ! Come on code writers this can be done but i dont know how to write code ! Anyway glad to see it there !

chris ables

Here's the link ! http://code.google.com/p/multiwii/wiki/ESCsCalibration

chris ables

In the code theres a link right above where you uncomment for esc calibration and i went to that link and it stated that there is no beeps while calibrating but instead there is blinking leds to let you know when it's done , about ten seconds it says ! It also says that it calibrates them to 1000 &a...

chris ables

Another update ! Boy was i wrong on not aerobatic ! He flew today and was flipping and rolling ! I figured that rc rate and lpf would lag so much it wouldn't perform that good ! He's only been flying for a very short time and impressed me very much today !

chris ables

Ok but do me one favor and try this before ruling the board out if you dont mind ! We run this setup today and even done some flips and rolls ! In your firmware set the gyro lpf on the lowest one , the one for worst case senario ! Then in gui set your pitch and roll p i d 's to P 2.5 I .025 D 20 and...

chris ables

http://www.rctimer.com/index.php?gOo=go ... oductname= i bought this and didnt have to configure anything in firmware and it works great ! CHEAP TOO! That is on my phone though , i havent tried pc yet and may have to change something to use on pc ! But i thought i'd share this with phone users !

chris ables

You did click settings in android gui and choose the right mwc version didn't you ? I had that problem when i first used mine ! Said it was connected but i couldn't get any readings . It was set on 1.9 version and i needed it on 2.0 !

chris ables

Update ! I got it flying now ! It seemed to have no vibration but hooked it up on bluetooth android gui and wow what sensative gyro's ! Lowered the lpf to lowest setting and turned the roll and pitch pid's to p- 2.5 i- 0.020 d- 20 and also turned rc rate to 50 and expo to 60 in gui ! Now it flies pr...

chris ables

I just watched that video you posted and i may be wrong but in the video it looked like your programing cable is offset and is not connected to all the pins on board ! I may be wrong , video is kinda fuzzy !

chris ables

Have you tried switching to a spektrum reciever ? Also i just built a quad x with a crius board and about couldnt get it right ! The biggest problem was vibration from mounting board directly to frame ! It seemed not to have any vibration , very well balanced props ! Try mounting the board on some t...

chris ables

Ok thanks , i have been selecting usbasp and usbtiny in aurduino 1.0 ! It works on both these settings but didnt know if it matters as to how it flashes to board !

chris ables

What kind of programmer comes with crius lite board? And which one do i choose in aurduino ?

chris ables

Put some 1050 kv motors on there and now that problem gone ! Now i hava another problem ! The quad drifts and the yaw doesnt hold ! Im using a multiwii lite board with a spektrum dx7s and the spektrum 8 channel reciever that came with radio With sattelite reciever! Also have the acc off ! Im running...

chris ables

Oh yeah it's not touchy either but it's just crazy as heck throttle response ! Wished i could make a vid but cant !

chris ables

Using 8x4.5 props ! It's not overpropped it just dont have a smooth throttle . Expo dont help this problem ! These motors start at about 40 percent throttle and move throttle one click and they shoot to about 80 percent ! I think they are just to high a kv for this setup! When gyro's try to correct ...

chris ables

I built a quad with 2212 1400kv motors and i have a bad problem i dont know how to fix ! The problem is that the motor is not very linear , meaning with one click on throttle and motors change speed dramaticly ! It's making the yaw not hold and making the motors surge up and down ! I need to know if...

chris ables

Cool vid ! That was a close call with that tree !

chris ables

Hey flyguy before you rule out that acc try lowering that level P to 4.5 instead of 9.0 !

chris ables

You cant trim acc in gui ! I know it. I've trimmed it with sticks. BUT I can't trim the acc in multiwii 2.0! I turned engine off, then i take max throttle then i trimmed with ROLL and PITCH sticks, but it didn't trim, LED don't lighting. It works for me in 2.0 ! You have to do this right when you h...

chris ables

Check motor and esc temprature when this happens ! Also are you using connectors between motors and esc's? If so take them off and solder wires together ! Have seen several people have trouble with motor connectors ! If you repaired dragon missiles then hardwiring wont be no problem at all !

chris ables

Well since i started this post i have seen a couple of people tried them stock and they said motors sputtered and shut off in flight with multiwii firmware and then i heard people say they work good with kk firmware! But i see that most people flashing esc's are doing these rctimer 30amp and having ...

not for flashing ! Flashing is installing new firmware in esc !

dont know what those 4400mah weigh but my batteries are 2200mah 50c and weigh 184grams ! I have 3500mah and my quad dont fly near as good with it due to heavier weight ! I find that the lighter i can make mine the better it flies ! Just my opinion though! Have fun at the cabin ! Ouch on the $100 ! T...

chris ables

Hi ! I see you flew heli's and that helps a little on pid's ! The p factor is just like a gyro gain and if to high it will oscilate just like a heli's tail rotor set to high ! Just try lowering the p .5 at a time until oscilation stops ! My friend is flying that same setup with dji frame and same mo...
