RE: Tuning 2-cycle for hovering
It isn't the cost of the engine that determines how well it will serve as a 3D two-stroke engine, but I understand what the poster is saying. It is important to find an engine that transitions well to begin with, period.
Truthfully, IMHO, were I to become enamored with the idea of small glow engine 3D flying, and I have, I would try to buy a Saito .82 four-stroke, even if I had to buy used.
On the other hand, I did buy a Rossi .45 3D engine a few years back, but haven't gotten to try it out as yet. We shall see how it stacks up against my Saito .82A on the same model (Harrier 46) after surgery this December 2nd. After chasing my health problems around for years, my pulmonologist accidently stumbled upon a giant goiter in my neck that was choking off my air supply and reducing my ability to swallow. What this could mean is that I might be back in the flying saddle again and with some extra energy to boot. Hurray!!!
