i have the Vendetta and all innards are TBS (powercube, core pro, Unify pro HV. TBS products are very high quality, and these are no exception. for the premium price, i would've preferred having the wires already soldered on the pads. with multishot enabled and coupled with Emax red bottoms (2300kv), these perform beautifully on default settings. i plan to put a set on my QAV-R soon, too.
