UMS 7-260cc Gas / Petrol 7 Cylinder Radial 4 Stroke Engine 1000 RPM-5700 RPM with 34 x 14 Prop 

That's what I am wondering. Why these type rc engines aren't used in ultralights. To powerful maybe. But I have seen tiny little turboprops that would be sick.

xKmotx yes she is a beauty!

@@173shatta Hi, how much does it weigh? Any pointers to a spec sheet?

@@manofsan I’m only 3 years late, but it weighs 6.7 kg

@@Smokeyr67 - okay, and what's the hp for this engine?

@@manofsan dude, have you heard of Google? It’s about 15hp, I found that in less than a minute.

Not quite, the wasp was a twin 9 cylinder. This is a 7 cylinder. But I get the reference.

Very manually, and very often.

that's an engine

@@SR-gs8zo would be an interesting thing to do tho, just slap together a bunch of them and let them do engine stuff

This is normal. I10 is car for peoples that havent money and want small car for town. This is small series rc engine for peoples that have money.

@@Dzordzikk Yes and lots of money

Yes the engine comes with spark plugs and ignition

1,3,5,7,2,4,6. Radial engines (with a common camshaft ring) all have this kind of firing order.

Hello no the engine doesn't come with the prop

@@173shatta .thanks

no

@@thomasmaxam8771 mate, ive worked on these carbs professionally for the last 30 odd years, i know how they work VERY intimately....and ive seen just about every failure there is, go back and read my post again...

Ja die Vergaser sind auch an Kettensägen dran. Aber hat der Sternmotor eine Impulsleitung ?

I’m tossing up between Moki 7 cylinders (either the 250 or 350) for a 1/4 scale Beaufighter, the big issue will be weight, but the sound will make it fly like a hummingbird full of helium 😂

@Christopher Giammarco thank you friend.

Only 13 hp ??? How much does it weigh? I would have thought that for something that size & displacement, it would be putting out twice the horsepower. Google search says it's 15.6 hp and 6.7 kg -- but anyway, I would love something with twice that horsepower and weight.
