I've noticed while practising in my small apartment that sometimes the blades are not equally level when looking at the Heli running head on... I think it may be the AC coming on and running for 5-10 minutes or so since the manual says they are subject to humidity, etc...
I read the manual and it says they need to be balanced by twisting them a bit, does this really work or should I look to purchase some better blades???...
Thanks guys,
Keith
