Full senthetic hey? Sounds about right. Same as what I use on all my 3D ships. Although we have added a little extra here in ZA just for some bells and whistles. The coolpower works well to keep my motors cool when their running rich enough for a full tank 3D session. My mate runs the same fuel through hes Saito .72 on hes Ultra-RC Yak-54 and the motor seems happy so I can't see why there is a need to re invent the wheel.
