MultiWii

@copterrichie: do you mean RC expo? I always fly with 40-45% expo, with BARO always ON, I feel smooth throttle, just that, no idea about ALT Hold . I think mahowik meant the ALT Hold for long time.

It's the same as previous ublox, just with new big antenna, eeprom. Looks like they follow EOSBandi solutions , just like the AIO board's usb re-inforcement. Cheap price, good quanlity and always try to fix.

@dramida: I've done the ALT tuning, and decided to stop at 3.0 15 10. It's similar to your PID, my tri now hold atitude very good, low 50cm, 3m or 20m. For the I term, it seems that at zero it's good, higher value like 20 30 I saw no noticeable difference except sometimes it loosed height slowly, I ...

I just checked and the actual values Alt PID are 3, 0.15, 7, i played a lot and i forgot the changes since it works satisfactory even in forward flight. Please see video and hear the engines when alt hold and gps pos hold are activated m Very very "beautiful" test-flight dramida! Were you...

Hi rbirdie! What OSD are you using? Very nice video but why you didn't try flying much higher, about 100-200m, I think the GPS alt is just for reference.

Never use AfroFlight so I cant help, why you dont ask this on AfroFlight forum?
For the BEC on ESC, you should remove all red wire and use an UBEC to power the board, or you just keep only one red wire from 1 ESC.

Hi dramida, thanks for your instructions. I've just tested tuning ALT recently for the method I read somewhere (maybe yours), yes luckily it's like your way, I put P&I at 0, and play with D. I increase big step to 30, it yoyo-ed , I decrease some steps downto 22, it looks fine. But I couldnot co...

* This is a function that need an open space space to test it. So It's basically something almost impossible to run multiple tests at home if you live inside a flat with no green outside => I can only test it once on the field with only few adjustments, reducing the possibilities to find empiricall...

That is cool.
I did not mean you would have to do all of the above:)
Have fun. It is a hobby, right?

...absolutely yes...it's a great hobby!

With some, it's just a hobby, great hobby, with others, it's the passion.

Hi dramida, about your idea - the ALT hold solution and the ALT PID 3.5 0.15 10, what is your tuning procedure? I want to test your idea. Tks!

The same as ublox 6m, but with eeprom for config storage, rechargeable battery, bigger antenna. I think it's perfect for just 4$ more .

I've tried many ways to make Ublox 6m works at the first boot, with EOSBandi patch for version 2.1, and here is the way I succeed : 1. De-solder the battery 2. Solder the pin 13+14 (just 13 and 14) 3. Apply EOSBandi instructions 4. After then, I mix some quadworker code. In the GPS.ino, UBLOX_init f...

Esc(s) are changed to HK F-30A reflashed with simonk fw, what a difference! After PID tuning, my tri is super stable now, even it's just in acro mode

Some boring clips

Love multiwii!

I replace 3 turnigy plush 30A with 3 F-30A reflashed with simonk fw. No need to change anything in the config file. It flies great, very stable

did you check the yaw-gyro direction?

So as you said, I need not to modify anything?

Hi, has anybody used custom simonk fw, and run 400khz mode with multiwii? we just need to reflash esc and enable #define I2C_SPEED 400000L in the sketch?

Hi snowzach, with higher P, your quad will work harder to resist outside force including your stick control, so with higher P you'll find that it's hard & slow to move your quad. The P term is different from kit to kit, my Tri has no serious problem with 25 P, but of course it wobbles a little. ...

Today I re-celebrate 3 ESCs (tur plush 30) with 2.1 code (ESC_CALIB_CANNOT_FLY in sketch), reduce MINCOMMAND from 1000 downto 900, increase max-throttle to 2000. The Tri now have more power, it seems to be lighter, I just can use about 40% of my throttle for taking off instead of 60% before. I reset...

sorry it's a hexa. yeah sure it'll be much interesting. I like the hovering feeling . Still learn to fly this kind of aircraft, much difference from normal fixed-wing planes and much fast-forward fear .

wait to see your tuned-quad clip, frogstrab.

I think you should remove all vibration as much as you can before do PID tuning. It seems that you face too much difficult .

Hi Carter, min 1250, max 1870, middle 1560, I never using the max input even with that settings.

Hi Wilco, I mean the tri turns slow with stick input. Without it, tri is almost tail-locked. 0.1 I is a big high value. Btw, do you think that higher I will decrease the effect of P? For PID tuning, I do the big step, then I stopped at 8.5 for P, when it flies, it oscillates a bit, so I decreased a ...

Hi wilco, I've just test increasing I term recently, it really solved about 80% the problem. It still sagged a bit but I stopped at 0.064 on both yaw, roll & pitch, it's dark and I couldnot fly anymore . Now my tri turns slowly. Maybe I'll do hard test & tuning tomorrow.

Hehe, I mean 1000g, sorry for the typo. Can't wait to try your solution, maybe next morning . Thanks again, I always think I as the sampling average speed, but automatic trim, it sounds more useful to tune.

Thank you, wilco1967! I will try next test day. Can you explain why I need to increase roll&pitch I?
My Tri uses alu arm, 50cm length, weight is about 1000kg including 3S2200 25C bat. DT750 kv motor with emax 10x4.7 prop.

Hi everyone! This is my very first multicopter, as I only fly fixed-wing. I've spent so much time on reading and building this tricopter, almost time is balancing propeller & reducing overall vibration. The 2nd flight test is fine this evening, windy field, start with acro mode for trimming &...

ok tks you, I see it's clear now.

Thank you, Jonit. Is there any difference between i2c & serial gps module? I see some recent boards prefer to use serial port for GPS.

Hi, I want to use both GUI & GPS, so the only solution with Crius SE is soldering an output port for I2C, and no need to use FC I2C-GPS NAV Module. Can somebody confirm that? Is sb using that method successfully?

Thanks!
