Very happy to see this one....
Perhaps in a liquid cooling option though?
Only issue, is finding a big enough plane to use it in...

Bud Nosen 3 Cylinder Engine P-51 (2 min 14 sec)

Precision Eagle Inline 3 Cylinder with Sachs 4.2 cylinders. The engine is 210cc with an estimated 24 horsepower. Its a monster.

Hello JKoch,


i see your tread and specially your avatar - just this question:
why and how do you use my engine in your avatar?

oh - another question: where do you come from?




mfg
Ralf

and another issue:

anny questions about well running 3 cylinders, Gears or so?


i do all constructions by myself,
the threecylinder and the twocylinder on the same pic are handmade by myself at home,
the gear is made by me,
the geared inline engione is complete engineered by me.



greetings,
Ralf

Nice to see you are still around...
Your engines are fantastic....You are in Europe someware?
You have a ISSUE with my Avitar?....

Of course - i have no issue that you use a pic of my engine in your avitar.... thats ok.
Here is this watercooled engine under "action" - (with a 30 x 28 - 4 Blade)

and the single cylinder with gear comes to the first test run this weekend. The target is to turn a 31" x 27" three blade "Spitfire - scale" Prop.

LOL....
The lanquage barrier can be difficult for sure...
I had followed your posting over on RCUNIverse...
For the COMP-ARF mustang.
Good to hear from you..

Have you thought about a 4 stroke inline twin with liquid cooling?
I realize that would have to go beyond that of just milling the bottom end, and using cyl's and pistons from a well know company...as I don't know any 4-stroke companies that are liquid cooled and for rc engine use..

Wow, nice stuff. Will you be bringing anything to the Joe Nall this yr?

I don't have any of these beuts....
I don't know if Mustang...will make the treck....he resigns in Germany??...

If you go, I may have to meet up with you....

Joe Nall?... hmm

If it is intersting for you americans to see this stuff live: maybe anybody feel free to pay my trip? Then 'im on the way.....

(probably next year in a P51... the time is rare)


I'm working at the moment at my P51 spinner... the Prop is already tested at my mock up plane (3m, 22 kg).... works very very well!

RR 258 mit P51 Prop 6 (1 min 40 sec)

You made that prop?

i made the "positive model" of the prop - blade. Once taken from original P51, (drawed on a wallpaper for the shape), then the mathmatics of the twist and profile with excel, taken the calculations in a 3D Cad - and just milling . . its a snap hmm... it takes two years. And beside i designed and tested my RR258 inline engine with the gear and make now the whole system become real.

The blades - these are special things of carbon - aramide - are manufactured by as-scaleparts.de

the gears to dirve such props are from me. Also the inline engine.... in front there is a Me 109 quarterscale-blade drivn by a 80ccm singel cyl. BFM

The whole setup looks insane and I'm sure the pictures dont do it any justice.
Back to the thread, I guess no one is using the ZDZ 150 though?

OMG!....
Amazing...

I didn't see that TBM has any instock yet...

Hello! I am researching and planning my DS P51 build. One of the Issues i am working on is the Cooling of the Motor? Any cool ideas would be appreciated...
