Can any one suggest a radial engine to suit a CM Pro/Hobbyking A6M Zero. It is suggested for a 40-50- CC Gas engine. The model is 2100 w.s., wt.is 6.5 Kg approx. I have had a look at the Saito FA-325R5D (53cc) glow 5 cylinder radial but it would be pretty tight in the cowl, which is 220 inside diameter and the Saito engine is 205 diameter, not including any onboard glow fittings or any other anclliaries. Any suggestions as to what I could use would be greatly appreciated. I would preder to use a radial if one the right size is available, or otherwise a twin cylinder
Thanks,
