RE: HoneyBee CP3
The CP3 is quite different from the CP2, unfortunatly the parts are not inerchangable, other than a flybar maybe. Seems they are wanting to make some cnc head parts but none seem to be available yet. So far I have had no need for them yet as I have only broken one sf arm so far. When set up correctly the CP3 flies really well, for me neway, though learning on it will likely be a chore of sorts. Best of luck on your first heli!
