Thanx for the info... I fly a lot... At least 3-4 times a week so I'm sure I will have to modify the radio access also... Sounds like I can fit a small gasser in there than right (25-33cc)? I'm new to gas too... So new that I don't have the motor yet A ST 2300 glow will suck fuel won't it?? Hell I thought my TT .46 Pro did...
