"Awesome. I'll be glad to help beta test it. I have multicopters and fixed-wings flying with APMs."

"I just backed it. Can't wait!"

"I'd like to see this as well.  I recall coming across a function to assign a spare channel to "save waypoint".  I've always wondered what those waypoints were used for. "

"Or tape a piece of foam over the APM's barometer/altimeter to protect it from the wind, if you aren't using the case and piece of foam they now provide for new 2.5's and see if this helps. You can blow onto the altimeter and affect…"

"I'm having this same problem. I'm using MP 1.2.34 and ArduCopter 2.9.1 for Tricopter. I had been able to use my 915mhz 3DR radios until I powered up and a friend connected to my tri when trying to connect to his quad, since we were both…"

"I've got everything back together and have flown 2.9 three more times and am very impressed with the AltHold and loiter, even in strong winds! The initial motor pause still keeps me on my toes, but then the magic happens! Even without sonar, it…"

"I don't think this will solve my problem, because the APM knows my throttle stick position based on the PWM value being transmitted by my DX8. If I'm hovering at 25% stick (say 1250 PWM) in Stabilize and switch to Alt_Hold, I need to push…"

"I may have just figured out my crash. I just put 3200mah back into my 3300mah battery that has some cycles on it. Is there any way to tell if an ESC hit low-voltage cutoff based on the .log data?  I'm repairing the broken arm and yaw…"

"If I'm overpowered, would it help to curve throttle so hover is near 50% mark instead of 30%?"

"Just when you think you have it figured out, gravity wins. I've been flying tricopters APM2 since 2.5 and have had tremendous success. I couldn't wait to install 2.9 and take advantage of the new features. I added some 1/4" foam…"

"How about a GWS Slo-Stick? The wing is large enough to get your gear in the air without too much speed and large control surfaces work well as slow speeds."

"I believe you need to use a different frequency for video tx/rx and rc controls. Even though the DX8 is FHSS, I've read to always use a different freq for each signal transmitted, and separate the antennae as much as possible to get best…"

"Someone tell me I'm wrong, but there is NOT a particular set of parameters that will work for all X8's. If we were all using the same servos, with same servo throws and arm lengths, and all had the control rods in the same slots in the…"

"It would look good, and futuristic, but EDFs perform poorly at a stall/hover. Needs to be super light weight. You could probably reach an enormous altitude in no time, but the decent may be less than spectacular. A tricopter-like yaw control would…"

"You may try increasing your Stab P gains, even though it may seem ok otherwise, just before the wobbles appear. That should tighten it up some."
