RE: Ak Models SU-27 glow engine selection
teebox:
Which F-4 is the "TF"? (Mine is built from Pavel Bosak's plans, circa 1990) He used a piped Rossi 60. I thought a larger, less exotic engine would deliver the same performance with less stress.
BTW, I started breaking in the OS 91FX today, and it is a real sweetheart. Started on the first hit and never missed a beat, unlike both the Tower and the Magnum, which were cranky about starting and couldn't handle the jumper tank fuel system. (The OS will go vertical with no loss of rpm. The Tower and the Magnum couldn't do that.)
