These are well worth the investment. The quality is outstanding and they function perfectly. They make micro adjustments not only possible, but EASY. Every helicopter should have these or at a minimum the cyclic and pitch set (I got both). These are so much more than bling- an add on that increases functionality and durability.
The service at FBL Rotors is top notch as well- great to deal with!
