This beast is destined for the firewall of the 1:3 Scale Barth Waco which is nearing completion. Naturally this engine is overkill but, hey, why not? Spent last weekend breaking in the motor at the Field. One gallon of gas, run rich, and no more than 3/4 throttle. With frequentContinue Reading

I could listen to that “lumpty lump” idle all day. I finally got a chance to get out to the field and run in the new Saito 33R3 I obtained from Tower Hobbies over the summer. As many of you know, this motor is going to go in my 1/4Continue Reading
