I changed three things from the plans in my build. Added area to the rudder (and repeated the shape of the wing tips and horizontal stab instead of the concave original. I mad a small opening in the scoop so it functions and any fuel spilled can exit, and I put an OS 70II in the nose for power. The weight of the larger rudder helped offset the larger engine. The only weight I added was 1/3 oz of split shot to one rwing tip to vbalance her laterally.





If I build another I will twist the engine so that the muffler is low and the top of the fuselage is smooth. I've seen a couple built that way and they look sharp.
