Status: offline 		Hello everybody, just a quick question regarding scale flying. Im thinking about the century L-Ranger for my rap 50 (o.s 50 hyper). Why is it that everytime I see a scale pic exhaust is blowing out the bottom? Ive never worked with (or even seen) a scale exhaust system, but the pic on centurys site shows the scale muffler and it looks like theres a fitting of some kind on the top that you can run tubing from (thats my take on it, please excuse my inexperience if this is not the case) How can you get smoke to blow from the exaust nozzles or exhaust pipes on the scale model.

Sincerely Pete

You can route it out with pipe, tube, etc, but any exhaust coming out on the top part will get oil and gooo all over the pretty paint job, so many of us flying glow scales dump it out the bottom. Extending the exhaust may cause overheating too, be careful

I saw this one a few weeks ago.(if it's the one I think it is, the address above won't get you there)the green and white Huey is a nice looking bit of gear, is a gasser that is less susceptible to heat build up, and even he didn't think is was worth the effort

The only glow engines that don't smoke horrifically are the Webra, Rossi, and Laser engines -or- any other engine that will run on FAI fuel (no nitro)

Then the gassers put out a little smoke...think about your weed wacker, not too bad...tolerable.

Electric is great, no mess, just worries about batteries and such.

Of course the very coolest is the turbine, and it is not messy, smells like a real aircraft, has cool noise, and will make you the envy of everyone at your field....LOL

They all fly, they all are fun. You LHS was right for you to learn on a glow machine.

I'm biulding the raptor longranger project, where can I find out about the engines that don't need Nitro? I don't like smoke, and I don't need super performance
