Hi Stephen

I cut my own wings and have done for a long time right back when i did control line combat witha PAW

fitted 2.5 desil and 55ft lines and 75ft lines .

As you can see from the photo i had to change the nose to let more air in as things were getting a little hot !!

Great looking model, might have to upset others and put a smelly thing in front, but a good design is a good design, must say I love it !! Cheers

AH!! putting a nitro in may give a problem with the tank etc the fuz would have to be a little deeper and wider
