i can understand your analysis....
anyway, as much as many modellers, i don t know how to reprofile a low needle mixture on a carb.... for me, it is a high precision part it is better to don t modify.... especially if you do it "blind", with no measuring equipment...
and again.... why do the engine manufacturer did not cure that? it is easyer for them than for us...
helicopter s engine, wich are the same as ours, in most of case, uses 30 per cent nitro... why? to cool the engine?
i ve also noticed that helicopter engine are more reliable than the same on an aircraft..... have i dreamed?
competitors flying f3a classic pattern were using a lot of nitro, same today with 4 strokes..... why?
i just want to understand, i feel like i ve used engine for 30 years, and still not able to tune them....without the recommended mix...
