I've built, flown and worn out a few FT Mini DR1's. The DR1is easy to build and fun to fly. With 56 inches of wing and a short coupled tail it makes you want to bang the sticks around to see what it'll do next. After another harder than intended landing (crash) I decided to build another DR1 instead of fixing it again. This one is different. It has a KFm-1 airfoil instead of the undercamber. Why KFm-1? Because I haven't built and flown an airplane with a KFm-1 wing yet. Lots of KFm-2 but no KFM-1. I'm hoping the KFm will make a good airplane even better.
Changing the shape of the airfoil is easy. Eliminate the undercamber crease. Add a 2.25" step on the underside. I had to change the wing saddles, wing struts and cabane struts to fit the KFm-1 profile. Assembling with the KFm wing is actually easier than the undercamber. Everything is flat, no angles.
Here are some build photos and the ready to maiden beauty shots.
