RE: OS .25FP Any good???
When the FP series went out of production I went around buyinig up all of the FP motors I could find, till thiis day I still have the 15FP, 20FP, 25FP, 35FP and 40FP in my collectiion, some new in the box (they are not for sale). I have 7 OS-25FP's in my collectiion, four of them will be used on a profile scale B-29. They are a great engine, remember it has a plain bushing but runs great. It being run for Stunt it might requiire some timing changes but worth buyinig.
