Vintage RC Sailplane Build. Multiplex LS7. Part 2 

I also have this glider, bought crashed off ebay. The tail incidence (EWD) was way to high when i restored it, reason being for the previous owners crash. It was 2.8 degrees I think yours will be the same-. It has to be 1.5 degrees. It has to modified before flying-very important. By adding a shim at the front of the top of the fin to bring it back to 1.5 degrees.

Hi ! Do you have a link where you bought this kit ? Thanks :)
