yes, I have ideas! I use the international rules, they have no special limit for motor or battery as I understand it, only that the prop must be dia + pitch =13 so 7x6 it is
plane must me 1935-1945 1/12 scele.
I use a spitfire, mega 16/15/3 and 2s2p oldie kokam 3300. AUW 850grams (700g lower limit)
I can easily get down to 700g just no time at the moment.
I get 17min flights on full power, which is more then enough for the 7min heats.
useing new 10C cells and the new glassfibre spit I think I can out power the .15 easy. but I se no reson to pull away too much, that only means the rules will change to my disadvantage.
not to forget that I will get a couple of extra points for flight time as I can get in the air atleast 8sec earlier then the others useing catapult
