- I would definitely go with the $70 OS .40FP. That was my first R/C engine,
- and I still have it. I've flown it for years, on several airplanes and in just
- about every conceivable environment, including subterranean! To be frank, I

- ahead of his' of the hobby shop person who is urging you to go with the OS
- .46SF as your first engine. Totally unnecessary. Counter-productive, in
- fact. As a beginner that kind of power is a distinct disadvantage. You need
- to take the .40 FP, and putt-putt a high-wing trainer around at about 1/3
- throttle for quite a while (months at least) before you get a rip-snortin'
- fancy, high-powered engine. It's like trying to learn to drive in a
- Lambourghini. (sp?)

- Regarding the need for a filter: completely unnecessary IMHO. I fly an
- R/C helicopter at a very dusty field. Helis spend a lot more time near the
- ground than do airplanes. I've flown my heli for almost two years at the same
- field without an air filter. (An astute rec.models.rc reader might cock an
- eyebrow here; I recently sent out an inquiry about getting more power from my
- OS .32 heli engine; that posting and this one may be related!!)
- Several people at my airplane and heli clubs have tried them, and at this
- point not a single person uses one on an airplane or a helicopter. They just
- don't seem to be worth the bother.
-
- All that having been said, the bottom line for a hobby is to have fun, and
- one thing that means is to do things the way you want to do them. You're the
- boss as far as your own gear is concerned! Based on your car background, you
- might want to goof around with air filters just for the heck of it.
