I am running two 150s successfully though not 100% as some might desire.
I am running the replacement ignition off of a three cell A123. I have a hotter plug in the #3 cylinder and I’m running a 28 x 12 prop (from memory) vs the 26x16 which I never liked. I’m also running the fuel pump also through Vogelsang Areoscale as was the ignition. Battery from NOBS batteries.
I'm not trying for high RPM and I fly sedated compared to some out on YouTube but it works for me. I’m flying a 12’ Telemaster and a BUSA N28 both with the setup as described. I had one in an F4U but wasn’t reliable at the time. I probably could but it back together now.
It’s disappointing that Moki sells an engine with as much need for tweaking and aftermarket additional stuff. I know there are those who made the stock setup work but I’m not one of them. I can’t say enough for Dr Gotz and his support.
Cheers,
Whit
