I wrote you a big long post here and lost it to a rcu server timeout. (I goofed around too long.)
In a nutshell I said my setup is much like your's. I made a few suggestions on running the Saito 150 and thought you'd be happy with it as the power plant.
PM me and I'll sit down and re-type my findings from the first 3 months I flew mine. Mainly fuel type, tank size , dummy radial use for cooling and some prop issues. My only big concern was reading where you planned on running the 3=bl 16x8. That may be more prop than the 150 likes. I have the D9 spinner in a 2bl and 3bl . Also a 3bl MA 16x8 sitting new in a cabinet. Would like to hear how your's does if you try it. I run the D9 2bl spinner with a 16x6 APC. Lot's of low end thrust for takeoffs and landings. Speed is still in the scale ballpark too. I fly fron a 250foot paved runway and need the extra takeoff and landing thrust.
Keep up the good work.[sm=thumbs_up.gif]
