I have purchased a ultra stik 60. LHS recommended a supertigre g90 2 stroke. After reading some of these threads, I'm a bit worried that since the instructions show a much lower range. I also, put about 8 ozs of wieght in the tail. Can someone let me know if the engine is too much and if it isn't, will the extra weight of the engine and the compensating added tail weight will overload my plane??


Thank you
