RE: CNC head
My .02 cents,
Dont put this kind of money into blinging this heli. If you do then break some part of the head it will cost that much more to fix. The bcpp is a great little heli but it is small and fragile. just work on your fying skills and save that $100 twords a nice Tx. A computer radio is the best upgrade for the bcpp. The new Tx can then be used with future helis. A HH gyro will also make this little guy much easier to learn on.
If you havent worked through RADD's I would recomend it. And try to say in in your comfort zone and stay in control at all times. The blade is very difficult to fly and take reat patience and many hours of practice. If you master flying wit the blade you will be able to fly any heli out there.
Just my .02, Noah
The only upgrades I would do on a bcpp if I had it to do over again is electronics upgrades. ie. Tx, gyro, servos, motors
you may also want to try moving the arms that go from the servo arms to the swash in a hole or 2 on the servo arm. This will tame down the cyclic response. The pitch may need to be adjusted f you do this. Also some flybar weights. Lastly keep in mind that learning setup and maintinance is equally important as learning how to fly the thing.
