ws_Alex posted a discussionAPM 2.5 cannot maintain altitude?!
My tricopter has APM2.5.2 on it. The firmware is 2.91b.It flies super well on Stab mode. When hovering, the throttle stick is around the center position.Then switch to Loit mode, it suddenly reduces the height a little bit and immediately increase the throttle to regain the altitude. I didn't tune any P.I.D, so I'm satisfied with it. This is the most case, about 50%.However, on other 50% case, it will increase or decrease altitude rapidly! The decrease is scary - It almost hit the ground some…See More

Ted Weerts posted a discussion2.9.1b flight data HUD jumps around, shows jitter when gps is plugged in
I have had a hell of a time getting my copter to fly right. It finally flies only ok in stabilize, but wouldnt even think about flying any auto mode. the last RTL attempt rocketed the copter toward a tree....while diagnosing, i found that the flight data HUD jumps around alot, while it looks like all of the videos ive seen have dead stable HUD. Im referring to the attitude gauge in the flight data screen. Randys videos show very stable gauges, and mine do not. I just cant figure it out. the…See More

Welcome to DIY Drones!
This is the home for everything about amateur Unmanned Aerial Vehicles (UAVs). Use the tabs and drop-down menus above to navigate the site. (About us/Site rules)
This community created the Arduino-based ArduPilot, the world's first universal autopilot (planes, multicopters of all sorts and ground rovers). The APM 2.5 autopilot hardware runs a variety of powerful free UAV software systems, including:
- ArduPlane, a pro-level UAV system for planes of all types
- ArduCopter, a fully-autonomous multicopter and heli UAV system
- ArduRover, a fully-autonomous ground-based vehicle system
I'm new to all this--where do I start? Are amateur UAVs legal? (yes)

How to succeed without really trying

My quad is flying better than it should. I almost feel guilty.
I slapped together a frame in a few hours. I use cheap props mounted on long shafts with cheap collets. The motors are not precisely aligned to the frame. The props are not balanced perfectly. Motor centers form a rectangle not a square. APM is strapped to the frame. I never bothered to calibrate compassmot. CG is not in the center of the…
