Brian :
My 36xBB runs very well with your P/L/R setup. Fabulous machine work.
So far, a few, short duration bench runs using 10% nitro/ 25% castor followed by several flights mounted on my Scrambler using 10% nitro and a 22% equal castor/syn blend. Needle not fully peaked just yet, although I'm confident that it could've been.
I'm getting close to feeding it more nitro- maybe next time out.
All in all, a really neat setup.
