A friend just flew the maiden flight on my US 40 today-Thanks Dave S ! I have a Saito 72 w/ on board ignition. A tame first flight and a whole different type of flying from a Eagle II. All worked well on the balance as the on board ignition sub c battery took care of most of the nose heavy properties. I installed a 12 oz fuel tank with no problem. Check the boards here for several good tips on building this plane. Good Luck with yours!
