OS .52 vs OS .61FX
Don't know why I'm asking - but which engine would you use on a Great Planes RV-4. The .52 is on the low end of the 4S scale and the .61 FX is off the charts . My concern is the weight and size of the FX on the nose. Don't neccessarily need unlimited vertical , but power is always good.
Thanks!
Thanks!
