Make sense, thanks. Still need to order some more stuff coming like multi-channel transmitter...only got car-used transmitters at the moment. Is Walkera Devo F7 a good choice? Don't want to use china band and too bulky.
Hi, 1st time assembling the kit without guided diagram, KIM240, S2 switch checked the main power switch, but no idea about S1? Is it a spare switch for other purpose?
Sorry, cap pic attached.
Btw, just finish my first trial in open area, looks ok though using 2S really not powerful enough. I guess indoor trial got 'floor effect' and afraid of throttle up. Btw, no idea why detecting RED bar...but YAW looks stable in tonights flight trial. Thanks ching.
