Default Bud Nosen P51

Has any old-timer flew a Nosen P51 with the geared .60 motor combo. If so, what size prop and how many RPMS did it turn. Thanks

I hope someone else can contribute also but.... I have seen it attempted many many many years ago and ended with a failed maiden flight . I dont remember the AUW or prop speeds but it was screeming and not enough runway on a 600 ft field .

Picked up a P51 Nosen kit back in November, it's still riding in the back of my HHR, I'm running out of room. It was a large estate sale at the Murrysville Auction.
All the Nosen P51's I seen had G62's. Was quite popular back in the day at IMAA fun ins. I do miss those.

I miss those IMAA days also . Lots of fun !!! With reference to the Nosen P51 I agree most flew on a G62 or 4.2 sachs .
My long gone friend Drake Edwards from here in NC flew his with a 12.6 triple cylinder Precision Eagle engine . That was the fastest P51 I have ever seen .

I have a friend that said people would drive across three states to see someone TRY to fly a Nosen plane with the Dubro reduction unit. He also said that you had to have the needle set perfect, good fuel,and even the weather had to be just right in order for one of them to STRUGGLE into the air...You might get a kick over this adapted Dubro reduction unit my buddy modified for me.. it has yet to be mounted in an air frame or flown on anything yet ...

I don' t think I have ever seen a video of a plane flying using the Dubro reduction ..

thanks for the replies all but I want to build one for electric. The plans call for the plane to weigh 16.5 lbs, which is not feasible.
I'm shooting for 21.5 lbs. and the motor I'm looking at will turn a 21x8 prop 6000 rpm with 21.615 lbs, of thrust. I know that is
only 1:1 power but I just want a sport flier not something I can yank off the ground and fly 150 mph. Any thoughts other than i'm nuts?

I think its feasible as an electric.. A little bit bigger than I would want to go as you would have tons of battery involved.. I fly some 1/4 WW1 electric.. but this would take more than that..

Forgot to add my electric Dubro conversion.. would only work in something floaty.. and its really just a fun project as it makes more sense to just buy a bigger electric motor !

Hmmm... 21.5 AUW ? I hope you will be able to achieve that . I would plan on choosing your wood carefully and lighten wherever you can . If you plan on fiberglassing and paint , film coveribg might save a little weight . Most of the Nosens flew near or well over 30lbs.

I know absolutely nothing about electric powered planes but I'm thinking that with an electric you're gonna generate a lot of heat in that thing. I also think you might need a 24" prop too. A buddy of mine had a couple of Nosen P51s. It is a BIG boy. I think the G62 would be marginal on power.

Carl , a really good G62 will fly that plane pretty well if its a lighter build. I was at a warbird fly in Owatonna Mn. one year and the guy had really done a lot of prop testing he was getting the most out of it he could.. I swear he had to be doing 80-90 mph with the G62 in it. Maybe it was just a freaky good G62? But it went pretty fast for that big of an airframe.

Shoot for 100W per pound as a start, try to build/rebuild for lightness and strength for a start. There are electric systems out there that will pull the wing's off but you want something that you can enjoy flying when you go out. there are plenty of formulas and programs to find a good power set up so do your research first.

In reply to the original question no! that's a lotta balsa! there are several electric motors that will haul it on the market today and would be interesting. I prefer gas. how far along are you? (old pic)

Default P51 progress

The wing is done and covered. The fuse is done and am final sanding for covering. Still working on exhaust manifold. Thanks for asking.

I am still fiddling with the exhaust manifold also. the look of what I have just doesn't turn me on at all, so I keep trying. meanwhile I am putting on a flite metal finish. My engine is a Quadra 75.

My type of modeler! Planes and tools everywhere. Great looking Mustang as well.
