RE: Too much oil.
Both engines has been broken in with 5 % nitro and 15 % Aerosynth 3 oil - ½ liter (1/8 gallon) each, and then the Super Tigre has been further broken in with 1 liter (1/4 gallon) 5 % nitro, 3 % M and 12 % ML70.
Should you brake in your engine with the same fuel mix, you have planned to use after the break in?
