Very Nice build. I also am building a Bristol M1.c 1/6th scale. I'm using sweitzer quarter scale plans, reduced. I changed the airfoil as I didn't like the undercambered one shown in the plans. I also scratch built everything, including the wheels which I found to be very difficult. I built them 3.5" used a black 3/8" tubing and put a smaller one inside to support the outer tube. As you can see in the photos, the joints are rough. I'm not real happy with them. Could you explain how you built the wheels?
