I dont have any comments. I am interested in your project. I plan to put a similar brushed fc i to a stma x5 body, and also have an 818 foe similar purposes, and will probably replicate or closely emulate your project. The toys like the x5 and 818 are great for all of those times hobby quads are overpowered or dangerous. This comment is just to say hello, i will be having my first programmable fc experience with my x5 frame and when the fc arrives in the mail. Looks not simple, and also like these kind of setups are harder than other more standard options, like a 250 brushless quad.
