RE: Cool Power 5% . Is it ok for tt39.
Do you think that I could mix my cool power 5% with some magnum 30% . If I do a half half mixture I think I will get 17.5 nitro and 19.5% oil . That way I wont be throwing 2 gallons of fuel away. My local (ish) stockist doesnt do any more than 15% cool power so I dont think that will do.
