There is a Piper cub out there 25 size arf (glow) I bet the 15 as a diesel would do fine swinging a 9x5 or 10x4 prop I just picked up a world models J-3 built up electric ARF will put in a new firewall and mount and use the OS10 davis conversion the 15 MVVS would be too much --this looks pretty beefy and good hardware 48.5 inch span conversion will be a breeze full house set up 2 aileron servos
