SUPER TIGRE 45 WON'T HOLD NEEDLE SETTING
I have a .45 which has run flawlessly from day one, that is until recently when mounted it in a different plane. Now it will not hold WOT needle setting without slowly leaning out. I replaced all fuel components and got the same results. Swapped engines and found no issues with plane setup. The only thing different I can point to is I ran a Enya #3 plug which is quite hot. I normally ran Fox standard in this engine. Could plug temp. have that much impact on engine performance? Fuel has always been 5-10% Omega. Thanks

Different plugs have different firing characteristics. A hot plug will tend to fire earlier than a cold one. This could cause detonation, which will make an engine gradually overheat. That could be what you're seeing.

The Fox R/C long idle bar plugs are perfect for ST45's. Your new plane setup could have tank distance and heigth issues compared to other plane and if your engine is inverted , side , or upright...........
