At the moment I am looking at a fixed wing UAV which can take-off by itself, so that you don't have to throw it off the ground.
A variable pitch propeller is used in conventional aircraft for this, and are usually engineered for the plane, but can one find off the shelf VP electrical motors?
I'm looking for about 9-16 inch prop diameter but it can be slightly smaller or bigger. First thing I looked at was this: http://www.hobbyking.com/hobbyking/store/__6220__Variable_pitch_prop_motor_set_10_34_Type_A.html
But I hear that one is pretty shit, suited for foam at best.
It needs to have a considerable amount of lift, so far I have only found this: http://www.amazon.com/RCECHO-1150KV-Brushless-Variable-Version/dp/B00L36K2FI/ref=sr_1_5?ie=UTF8&qid=1427303620&sr=8-5&keywords=variable+pitch as a possible candidate but it has virtually zero info, reviews or ratings.
If anyone has a variable pitch build or any suggestions concerning variable pitch props for mid size UAV's available off the shelf, then that'd be appreciated because It seems like proper VP-systems are nowhere to be found on the market.
