Do away with the cheat hole, as Dave says u/c beef up and get that turbine bolted in.
Now look to see where you can get the fuel tanks in! You iwill need to get at least 2 litres of fuel in for a decent flight! Post your pics and this will make a good thread.
I like EDF but on a smaller scale (when I can't fly turbines), I love turbines, they push the boundaries of the hobby!
