I just put together an HK 250 gt with a Align 250 stock esc and motor I purchased off ebay for this build. The problem is that the motor doesn't seem to have alot of power ( this is aligns older style motor not the sp version)I have a Trex 250 heli thats seems to have endless power. (sp style motor) I'm not sure if it,s the esc or motor. I was looking for some input on how to check these or is this just the way the older style motor acts? I need to run about 70% throttle to get it to hover at 5 deg. pitch and it feels real lazy. At 85% it feels like my trex 250 which is 60% @5 deg pitch to hover.I have checked for binds and everything else. The HK flys nice but I don't have any power to pull out of a bad situation. And still being a heli rookie I tend to make a Oops now and then.
