Stump,

XTREME GRIPS AND XTREME BLADES; period, over and out. No TBE that I couldn't get rid of like when using the MicroHeli. I really had issues with the Microheli grips. And You don't need the microheli lower head to make it work; just your stock e-flite aluminum or plastic (I think) but I know they are pretty much drop in; only took a few minutes, including installing the blades. They seem very well balanced.

NOTEABLY BETTER LIFT ! !
