I just upgraded my tricopter from 3.2.1 to 3.3 and got bit by the reversed servo bug. As those of you with tricopters know, there has been a variable called RC7_REV which you can use to ensure the APM/Pixhawk moves the tail servo in the correct direc

Read more…I've been using a Canon SX230 HS on multicopters for mapping and vertical imaging. I think it does a great job and takes fantastic pictures....but it's heavy! At 220 grams it seriously shortens flight time over other, lighter, non-GPS cameras. I'd li

Read more…I just installed 3.1 RC-7 on a tricopter and tried out Autotune and Drift mode. I thought I'd post the results as there don't seem to be a lot of tri's running APMs.
The tricopter in question is a resurrected GetFPV Delrin Tricopter kit. By "resurrect

This happened before a number of iter
