"Writing the code to run the obstacle avoidance is somewhat trivial, the problem I am having is incorporating it with the Mission Planner firmware, without having to type all of our own parameters in the thousands of lines of source code, which the…"

VTOL FPV tilt rotor

Can I switch between a heli mode (twin prop) using the elevator as roll control then, after building speed, manually or automatically switch it to plane mode where it would use the speed differences in the propellers for roll movements and the elevator for pitch. Also the rotors would be on tilt motors that would need to be thrust vectoring I believe. I saw a tilt rotor wing design and was wondering if this hardware can do the same thing.I found a video yet I'm updating this post so I haven't…See More

"No one has implemented avoidance. It would be pretty trivial to do, but hard to support across numerous configs. Have at it if you feel up to it. Jason"

Are sonar sensors only programmed for altitude hold or can they be used for avoidance?Thanks for you replies :)See More

Wesley Chuen replied to Tim's discussion Hexa/octo copter help

"30 mins of flight time is going to be tough for a heavy lifter. I have a hexa with 880KV motor running in 3s with 10" prop. Powered by 2x 8400mAh Lipo, I get only 15 minutes of flight time with the total weight of 3.3Kg. "

Hexa/octo copter help

I'm trying to build a new multicopter for AP work, I'm thinking mostly videos but maybe pictures as well. I have some RC flying experience with my 480 heli but it can't do that things that a hex can. Here are my guidelines.It should be able to carry a Cannon 60D (1.6 lbs.) and be stable with it.I'm going to use Arducopter with hardware 2.0.Basically I need help finding bodies that are suitable, I need help finding the most efficient prop/motor combo and where to buy then in the U.S.I'd like to…See More
