I've had a couple BCP's for a while...went through a few 4 in 1 units...went through motors (main and tail), have the dual tail motor mod and have been running 3s1p 800 in it when I was flying it last ...got the B- 400, T-Rex 450 and a couple SJM 500's so I haven't flew the BCP for a while...went to fly it the other day and not much power...put in another new brushed motor and the same results...even in idle up barely enough to get a foot off the ground...pitch checks out good..I was wondering if I smoked another 4 in 1 unit......or could I get the BL conversion and would the 4 in 1 be okay? I don't know much about these integrated units.....it's a fun little heli to fly....wouldn't mind doing the BL conversion....but hate to buy another 4 in 1 unit...beside it, the parts are sooooo cheap....any help would be appreciated ....this BCP has an Airwolf body and 9 LEDs...looks pretty cool....look better actually in the air though.............[8D]
