I run an LA-46 on a tongue muffler (all holes open) in my Vector 40 with 5% nitro, 20% oil mix and a 12.5 X 4 APC prop. I have tried a couple other fuels (5% nitro/18% oil, 10% nitro/18% oil, and 10% nitro/20% oil) and had either power issues or overheating. I've found that with the heat and extreme humidity in our climates that even seemingly small fuel changes can throw the motor run off.
Before takeoff I set the needle to where the motor is in 2 cycle and just cracking into a 4 cycle every couple seconds. The lap time is around 5.1-5.2.
