Thanks Hydro. I have only just runit a bit as a test. There is still much to do and adjustments to make. I may add a resistor before the PC board I made to dim the lights a bit. I bought a Flysky 3 radio, which is lame on instructions, so Ill have to play with it a bit. Im sure it will do expo trimming. The prop I used was the one that came with the kit, the plastic Midwest one. Im not sure what pitch it is, but it measures 1.6" in Dia. Ive looked into a different prop, but not sure if I want a 3 blade, 4 blade, what pitch etc.. I can get a max 2", which I think may be way too big..
