Fredo, your kinda shooting down every excuse I have NOT to use the Saito. I never thought about the small header tank, I was going to do the same thing many Moons ago with another plane and wondered how it might work. What size is you primary tank and how long can you fly on it. I have never had the Saito in a plane, I have run it up many times in the back yard just to listen to it. Mine has the dual pipes and primes very easily by holding my finger over the end of the right pipe ( the one with the tank pressure. )

Do you use an onboard glow or do you feel any need to ? I just ordered a new Taurus TS52 last night which means IF I use the Saito in the Ultimate I'll have to buy a plane for the Taurus, Oh Dear !!
