Hey there,
I don't remember who asked about the 108. I have it in mine .the only problem is i think the tank is to high. The fuel just pours right out into the carb. It's a real PIA to get it started. Maybe a fuel regulator will work. Im going to try to mount the tank a little lower and see what happens..
When I'm trying to hover I loose power and it does a nice tailslide. I have no power from 1/2 to full power.. It just craps out,and I got to bailout of the hover....
Good Luck,
Frank
