wow, so many replies ![]() the full scale one looks ugly only because there is no paint job. Picture the full scale Katana with a paint job like krills (jason nolls) or like the futana 90 ![]() that would look awsome |

yup in summer the heat is bad always 100+ - so we look ugly for a few months but must fly - we run moki180's so they get a little hot - the guys using 24cc gas are ok but dont have proper 3d power - give and take!!

I would think that cowl on and proper ducting is more efficient cooling than cowl off. With a small single cylinder glow it may be hard to make that proper ducting though.
