Stephane

I do not know the answer to that Stephane. I don't think there is much difference. I would suggest you make a card template using the Jet 1A leg and wheel and then make the cut outs in the Scorpion fuselage . All I did was to make the cut out for the retract, fit the retract and leg / wheel, raise the gear and then draw round the wheel with a marker pen. I then cut out the opening and finished it with a Dremel sanding drum.

Best regards
