I agree this Forum is great and so are the members, everyone is so helpful it is really a pleasure to be part of it. I want to thank all you guys for your input. I also want to ask for some advise on an ARF suitable for this engine. The original model I got for this engine (proposed by my inexperienced hobby shop without bad intentions) the great planes super Stearman biplane ( a beautiful model) was vetoe'd by the manufacturer when I called them advising the airframe will not handle it. Maybe some of you guys already owning a Fuji bt32 can advise me what model it is installed on? I am an intermediate flyer. Thanks again
