This is a puzzling problem to this neophyte...how can it be: tail rotor not spinning, but when I spin-up, the tail rotates in the same direction as the rotor. Left rudder will do nothing. Cyclic towards the 5 o'clock position seems to help. It doesn't do this all the time. Half the time it acts like the RADD doc suggests. I posted this elsewhere and have had a suggestion that this might be somewhat normal?? I don't think so. Applying more throttle causes acceleration of tail rotating in same direction as rotor. I'm still doing the Battery One exercise in RADD:

I'm new to RC helis, but have piloted the real machines in the past. I'm using the RADD method of learning, and am having a strange problem. It seems as though Newton's law on reaction has been violated in my BCP. When I add power, per the laws of physics and the RADD school information, as the blade turns clockwise , looking top down, upon applying power, and with neutral trims and cyclic, the tail boom should attempt to rotate counter- clockwise . (Indeed it does some times.) Frequently though, the tail boom goes in the same direction as the main rotor as I smoothly apply power. I have neutral or left rudder applied and no effect. If I add a bit more power, supposedly breaking inertia and creating some more torque, the tail actually accelerates in the same direction as main rotor rotation...scarey. I've tried to compensate with cyclic, and working it towards the 5 o'clock direction seems to help, when applied at spin-up.

The thing that bothers me is that it seems somewhat intermittent. I may be able to practice Battery One a bunch of times, with the tail responding properly and use of right rudder stabilizes the torque OK. Then I might take a break and when I plug the battery back in and try another round, I may run into the problem with the tail rotating clockwise with the main rotor.

I'm thinking I might be a bit nose heavy on the CG, and perhaps, the left front skid is acting as a pivot in some fashion, as I apply throttle on spin-up. Being a newbie here, even with a bit of physics and rotorcraft understanding, I thought maybe some folks in this forum may have seen this problem with the Blade CP...any ideas?

Thanks in advance for all the fine sharing and participation that goes on here...BIG fun!
