"start with the load, endurance, pack-ability, and reliability requirements then find a motor prop combination that comes close and design around it.
The weight can vary greatly. For example, I have two heavy quads with basically the same power…"
"Yes, but ALL gimbals are servo controlled in one way or another.
What this means, is for a brushless gimbal you will need a brushless gimbal controller. This does not need to have it's own stabilization capability, just the ability to…"
"Had a similar problem. Ended up being a trim issue. Had to reset centers on the elevon servos and the control horns. Fixed the problem.
As for throttle, your cruise throttle setting may be too low. Try turning on throttle pass-through."
"I've had this problem. Solution was to re-rig the elevons so no subtrim was required. I.e. trimmed flight is center PWM values. If you have a lot of subtrim the Arduplane software will have major problems with pitch control. Been there.…"
"I did some work in this area last year. We never built the system designed but it should work. We decided to go with redundant receivers, one connected to the APM and one not. The key was to use a PowerBox receiver failsafe system. All the servo…"
"This has been tried, and using an APM. Couldn't do it do to the French. They ended up doing a flight to an island that was the same distance. . It was all on TV done my James May (Top Gear). It's all on YouTube.
Oh, and they did it with a…"
"Are the hot motors rotating CW (from top)? And, what type of motors are they? Some motors build a fan into the bell casing which is rotating the wrong direction for the reverse pitch pair, thus those motors do not cool as well as the others. Same…"
"I'd second the mass comment. I tried mounting the flight batteries on the gimbal mount and it immediately reduced the induced and high freq vibration. My gimbal is suspended with 3 rubber mounts in compression. "
"There is a workflow required for Virtualdub deshaking and you are doing on a few of the steps. These are what we do:
1. Convert the video to divx or avi raw from out-of-camera format using WinX HD Converter.
2. Run Virtualdub/Deshaker process with…"
"Don't bother. Windows 8 mobile won't run generic Windows apps. Apps must be specifically developed for Windows 8. APM planner is not.
To run APM Planner on Windows 8 you need a full pc version. Won't work on tablet (non-pc…"
"Ok, these "look" like E-Flight 52. Even if they are as large as the 160 there is no way this thing is getting more than 20 min flight time (E-Flite Power 160, 10s4p6000, 20x6, 500g frame weight, 11kg GW) Other setups can get as much as…"
