Default RE: MVVS 120 boxer engine

Ok, I'm new here.
Seems to be an old thread, maybe someone still monitors it?
I recently aquired a brand new MVVS 120 Twin, installed it in a Drastik 120.
A 16x6 two blade prop gives me about 8500 RPM.
A 14x7 three blade gives me about 10000 RPM.
I'm using OS no 8 glowplugs, 10% nitro, 20% oil.(50/50 castor&Klotz)

I have absolutely no complaints about the power, 1/2 throttle it climbs vertical.
On the 16x6.
I do however also get the low throttle cutout at idle.

I have designed and built a PIC circuit to maintain glow at low throttle settings(not installed yet),
and can live with that solution.

Main questions, am I in the ballpark with the prop, fuel, and glowplug setup?

Oh, some pictures...
