I have been using HItec 845mg in everything I build, big or small so that I can use them when I sell off or "put-in" a model. I am convinced that most in the hobby "overbuild" I do not shoot holes in the sky. I am happy doing 6 landings and going home at noon time. Installing saito 180. Only large glow engines for me as I try to get out of the hobby, try try try..Have not received my pkg yet. Lola the bulldog is waiting at the window for the diesel sound (UPS truck.) Good luck with test flight Jerry, then write ?
