Awesome work! What are you running for your PID settings?
Are you using any motor tilt?

I do not know where to begin troubleshooting. I did nothing to my tricopter. Tonight I tried to figure it out. I plugged in the battery and...... The servo works properly the arduino arms normaly It passes the "shake test" All systems are nominal. Intermittent problems are the hardest to d...

I got some time to fly my tri today. Everything checked out and I had an uneventful flight. ( nice! ) After the flight I set the throttle to mid point and shook it in various axis' and no motor stoppage was noted. I put the tri away and watched the Super Bowl. At half time I tried to fly again. No t...

Thankyou for your experienced opinion.

Perhaps, look in the videos section and see where Alex is going.

That is such a nice, clean build! Well done. Thank you for the nice photo
documentation. Every single detail is well though out for simplicity,economy,
maintainability, and function. I know it has been asked before, but Alex,
what are YOUR feelings about a tricopter versus a quadcopter?

I will be sure to check for hot components from now on.
Thanks. But why would an ESC or motor run hot
at 50% hover power?

My esc's are very basic with no timing adjustment. I just set the batteries for NMh and plugged each ESC directly into the reciever and calibrated with transmitter stick position individually. The servo not operating is odd. Prior to this flight, the servo would not operate on power up. I tried plug...

About 3 minutes into this video I had an uncontrolled pitch-over. I repaired and flew again and again part way through the flight I got an uncontrolled roll-over. I repaired again and everything tested out OK. Due to night fall , I tried again the next day. Upon power-up I had no servo control. I ha...

Here it is, assembled.

Here is a view of the component pieces.
Simple and repair-able for a beginner.

This is my first attempt at making a small tricopter frame. The arms are 7/16" aluminum tubing. This is pretty cheap and easy to replace/repair. I used a blade grip for the pivot. The 3 nacelles are modular and have foam fairings/bumpers made of urethane foam. Simple, cheap and easy. I hope it ...

Here is the copper side.

I just finished my replication of Ilmars' board. I am making a small acrobatic tricopter, and this is my first try at making circuit boards and soldering on such a small scale! ( at least to me! ) I have a newfound respect for the soldering skills of some of the people on this board. If some of you ...
