2 Quick questions. With the thrust tube in the f16 it is an amazingly tight fit as in denting the thrust tube a bit to get the wooden former around it has everyone else shaved a small bit off the former to get round this or just used a little brute force ?? The other one is how far from the bell mout should the turbine exhaust cone be i have the wren mw54mk3 if that matters

Cheers
