A while back I did some testing for Hubsan after one of their plus models flew away on me. They asked me what could have helped in preventing it from flying away and I gave them a bunch of input. I was very surprised when Hubsan sent me this quad which contained everything I asked for! It is a newer version of the normal H107C+ and I don't think this bird ever came to retail as I was not informed by Hubsan that they would do so. To be honest, I think it was too much to ask money-wise
so I believe they just put all I asked for in this one model sorta as a gift for all the helpful info and input I gave them to make updates to make the H501S, H502 and H502e better flying models.
Here is a run-down on its features that set it apart from the retail version..
- Faster Yaw Speed
-1080P Cam
-Faster Descent
-New Radio Protocol
Quite happy with everything except now no Deviation since the protocol was changed!
