RE: .15 ENGINE FOR MODELTECH'S ME-109 ARF
In RCCA 2548 scale combat, the planes are built to a maximum 48 inch span and a minimum weight of 3.25 poinds, and we run an OS25FX with a 10-3 prop at around 14,500 rpm. It pulls like a tractor, but the lower pitch keeps our max airspeed to around 60-65 mph straight and level, but the pull good in turns..just a little fyi..
