TBS DISCOVERY - New quadrocopter frame

[soundshock]

Hi,

the maiden of my Discovery resulted in a flip-roll combination over the right front arm just straight from the start and broke the back left prop after completing a 1/2 flip in about 40cm height (won´t post the video ... too embarrasing).

As I am a total beginner I thoroughly checked all these items before and after the "flight" (it looked way more like a jump).

All these items seem to be OK:

- Solder connectiions
- correct servo connection order
- CG Balancing seems right (with LiPo and GoPro installed)
- Ailerons, Elevation, Throttle and Rudder are responding accordingly as they should in the DJI Naza Assistant
- GPS/ATTI/Manual Switch is properly configured in the NAZA Assistant
- Naza VU LED blinks accordingly to the state the FC is in
- TBS Core lights up as it should
- TBS Camera/VTX/Goggles are working nicely
- Graupner Props are nicely balanced and CW and CCW is properly configured
- Motors turn in the right direction

In my test setup (with no props and a piece of tape on motor shafts, to test the motor direction) it occured to me, that Motor 1 (right front) and Motor 3 (left back) are much slower than M2 and M4. By changing servo connections i was able to speed up the slower 2 Motors by decreasing the speed of the other ones. Therefore i think the Discovery setup is working nicely and the problem might be in my programming of my graupner mx 16.

Any suggestions ?

Or simply flash your ESC's with the Wii code. Berkley (on OpenPilot Forums) managed to get some excellent performance with flashed ESCs and Juz's motors.

Here's the link to his post about it and the code he used: http://forums.openpilot.org/topic/11...sc/#entry94851

Yes this is very true! i could not find that link...

I updated my post with the link...

So I've seen some post about using ear plugs to stop the GoPro jello affect. Here's my first try at it. More to come at 1080p 30fps. I've got a few more ideas that I might try as well. I'll share the info as avaialbe.

These are the ear plugs used on this setup.

here is mine from yesterday, first flight on the ear plug fix...had to land as it started raining (you can see the lightning at around 0:43 in the distance and some rain drops) same general design as everyone else, used 12 green ear plugs and still use the rubber band for extra insurance

Trappy, i went back through the core setup menu, turned it all off then turned it all back on and now i get a random second voltage from time to time next to the pack voltage. I'd just go with it's the "other voltage" except it doesn't make since, it starts at 5v then slowly rises like a clock. seen it go to 6.8 sitting on the table not flying. If i reboot it goes away but twice out of 5 or so times it comes back on. What is that?

Legend! I just updated the same F20A with wii_esc_bs_nfet.zip and voila! I can't get the motor to cog/go out of sync no matter how aggressive I fly it. It's unbelievable, first of all never thought esc could be flashed twice , and secondly I don't have to buy more! $stuff$ cool...

Thank you everyone who made a suggestion towards troubleshooting this problem. I'm going to night FPV fly tonight as my FPV maiden, right after getting it to hover without these random motor stops. superb.

I Had issues running RCTiger 3506's - they cogged or lost timing with every esc i tried. I switched to HobbyKing F-30's and reflashed with Falco-Wii-esc firmware - HERE.

This fixed the problem instantly.

Cool thanks for the info guy's!

Hmm... i think it's time i started to try to flash my own esc now... (untill now some els was helping me out in that department)

it's very straightforward, i bought an atmel programmer (rather than a 3rd party unit) and use the AVR studio software.

i made my own lead and just use a simple sprung pin contact which i hold on to the esc - tried to make a more robust clip-on device, but a hold-on solution works fine.

with the F-30's you only need to knife out a small rectangle of heatshrink, as the pins are in a single row.

again thankls for the info... I will give it try!
