heliguy, thanks for the info and insight on my question, i first learn to hover and fly on a shuttle, so i am beyond a total beginner, then i did pick up a used gmp cobra which i do still have but, the tail was always twitching, and never upgraded, then bought and still have a nexus(with 46) no electronics just heli and motor, then got used x-cell, with free concept, so i have been to the flying field(sepulveda basin) couple times to ask and observed the experienced flyers, but not to many willing helpful helps around, so it comes down where i am trying to learn on my own. since several guys had x-cell(pro,se) so i saw one in the papers not thinking that i should have bought a more updated model. heliguy, do you know about tsk helis? like how many models?
