I have put on decals square to edges, measure with rulers ect. and they don't look right. It an optical illusion or something. What I found that works is to forget all that and put the decal on and position it so it looks good by just using your eyes. Works every time.

Hello,   I am not sure how to position the wing insignia on the P51B Mustang I am building.  I have studied what photos are available and cannot exactly figure it out.  The idea I am thinking may be best is to have the edges 90 degrees to the side of the fuselage and invasion strips.  However, the edges could be centered by the width of the wing, too. 

If you have done this before, please help.  Thanks

BYU on here should have one or two . I think he had plans to produce new ones out of F/G and ones for the Akrobat sister ship

The factory Fox 35 Super Stunt that I know of was a steel piston & liner which was a higher timed with larger intake and exhaust ports. I never ran a Super Sunt, but our local Fox 35 Stunt expert prefers the original timing. Fox did make a stock timed ABC set that's a good runner. I currently use it to power my Flight Streak and can complete the pattern with only 3oz of fuel with No Burp (can only fit a small tank on the Streak) using a venturi restrictor.
 Post a photo of the engine and the box it came in would help ID the engine.
