I know I said I wanted to use a 4-cycle on my Master Series P-47 build but I'm starting to lean towards putting this on it...
Ok. That was pretty cool and exciting! Also reminded me of why I fly electric. That seemed like some serious power!Bought this engine on tuesday from my LHS, $35, siezed solid. Freed it up, slapped a prop, glow plug in it, and off it went! Still have some work to do but this thing's easily just as powerful as a modern 40-size two cycle and it WILL fly. And I love that tiny muffler on it, louder than all hell but quite compact.

Over 1 horsepower. Thing's a rival to a modern OS 46AX(I have one of these, too, they turn the same numbers on the same prop/fuel). Why any time I go to adjust the idle speed screw on the carb you can see the screwdriver twitching; I have to get uncomfortably close to the prop to make said adjustments.Ok.

If my house wasnt slotted into a forest I probably wouldnt fly at a field at all. I'm rural enough that the noise is a total nonissue as is space. Just too many trees around.Electrics have there place but hard to beat the smell of Nitro, I can fly most of my electrics at home but when it comes to the gas and glow planes have to go to the field.

Don't assume a 'modern' glow engine is automatically more powerful. They tend to be designed specifically for RC work and to meet strict noise limits.
...what noise limits? Far as I can tell there are no restrictions in the lawbooks governing noise and emissions from model aircraft engines. They can be as loud and smokey as desired.JennyC6

'Back in the day' good engines were simply designed to be as powerful as possible and the designers got pretty good at achieving it.
FT P47 RAzorback with that 10-5-3 prop would look, sound boss, and I'd have a 3:1 thrust/weight ratio besides!
Me too.I want to see that!
I'll probably be ordering the speedbuild kit either later this week or next week. We shall see how the paychecks fall.I want to see that!
A few clubs in the UK that have infuriatingly annoying NIMBY neighbors are not going to make an entire industry change its policies. What does make companies change policies is legislation, and far as I can tell there is no noise or emission regulation applicable to model aircraft engines. They are allowed to be as loud and smokey as desired.Many clubs in the UK operate specific and measured decibel noise limits. A club can face closure for causing a noise disturbance to nearby by residents. Some engines suffer more than others from the effects of exhaust back pressure.
