Covetski,

Please forgive me for partially disagreeing with dieseldan. BUT. Diesel does not increase hp much, a big prop increased airframe performance. Diesel is cooler running. Diesel is more frugal but not half the fuel consumption. A 10 oz glow tank for 15 minutes will be a 6oz diesel tank for 17 minutes. My Mecoa .47 turned a mas 11*6 at 13K rpm and ran 20 minutes+ on a 8 oz tank. My TT GP .42 turns a mas 11*6 at 11,200 rpm for 15 minutes on a 4 oz tank of diesel. With skillful tuning throttle response can be quite good but extended idling can have a slight delay especially when cold. Buy Davis plane fuel from www.omnimodels.com for the lowest cost. Free shipping over $100.00 and NO Has-mat!!!!!!! Diesels sound like a small Harley at idle and my MECOA .46 made a cool two stroke motor cycle sound at part throttle and great acceleration.

Try it you will like it.
