I'm building a Bronco and the motor specifications call for 370-425 1000kv (min). Does that mean 1000kv or higher, or is it 1000kv or lower? Hopefully, with twin engines this will be a high wing plane I can keep in the air. 5 Tiny Trainers, 4 Blu-Babys, and 2 Simple Cubs all were a struggle to keep in the air all came down on their own. However, the Spitfire, Scout, and F-22 were a real pleasure to fly. They just seemed more intuitive. At first I thought I was building the high wings wrong but it is the same on ClearView also.
