I have had one of these before, I once I got my head around it it worked fine, keeps weight down by combined esc, a bonus motor wires already soldered in place
I bought this little guy to go with a Micro Aces kit I purchased. I had totally forgotten I purchased the kit. while cleaning up the shop, I found the box. So I ordered this little guy for control. I like it because its small and lightweight. I dont like the fact that it came with a connector already connected to esc, but no mating connector to solder to motor wires. I also changed the length of the jst power cable as it was way to short for any real use. Other than that I love that it has a channels. one channel can be used as a dual aileron port by jumping a pad while powering on the unit, which will make this even more user friendly. This is Definitely worth the price. I did put letters on the plugs on the board just to make things easier when final set comes around.
