Anyone know if there are any scaled down P-38:s flying around ?

If not then will two of these 45 hp ZENOAH ultralite engines be enuf to power lets say a 2/3 size manned Lightning ?

How fast could it be..any educated quess ?



Here is about the real P-38:

Ehem !

I did some google search and found a 80% project:

This is supposed to go 315 mph at the cost of $ 300 000 per piece. :D

I was thinking something way cheaper.

There was a scaled down P-38 at I believe was Livermore Ca. I think it was about 2/3 scale. Not sure if it's still there or not. I'm sure someone on here knows more about it.

How bizarre! I had a dream about this last night before I saw this post.
I was at Reno, and Someone put in two Falcons in their 2/3 scale P-38, one running the opposite direction. In my dream, the replica was clearly an XP-38...it passed the Thunder Mustang just before home pylon....

Thats it...no more tequila before bedtime...

With 90 horsepower total, it would have to be built like this!

It's not @ LVK anymore.
Around Three years ago it was donated to the museum down in
Santa Maria CA.

I see 100 mph with a 65 hp 3/4 scale Mustang.

Now what if you forget about the scale looks in the concept, but make it the most aerodynamical twinboom and enhance those 45 hp engines to produce 70 hp each => 200 mph possible ?

And if keeping it in scale but scale it possibly down to 3/5 size ?


Dave Morss,

What engines did that pictured P-38 use ?

Here are specs for the P-38:

http://home.worldonline.dk/winthrop/p38.html


A 3/4 size P-38 spans at 11,8875 meters ( 39 feet ).

A 3/5 size plane would be spanning 9,51 meters.

A 4/7 size would be 9,05 meters.

A 1/2 size one 7,93 m ( 26 feet ).

Ok,

Thanks Dave. Did you test fly it ? Does it have variable pitch props ?

Dave,

One more question; did you fly it on one engine only ? Would it have flown with one engine alone..I mean do you think it would have been in control and brought you home safely ?

rgds,

Juke

I talked with him in his hangar at LVK one day. Sorry his name escapes me. It was half size and yes Sazuki power. He said it was underpowered. Flew OK, but not the performance he had hoped for. Donated? I guess that's why I haven't seen it up in a while.

Dave, since you flew it perhaps you can comment on the performance.

Nice workmanship.

This is a very good quality in a twin.

This Hanriot H 232.2 ( by famous Rene Hanriots factory of France ) that is in the other thread by me had at least one bad habit..small engines and inadequate training caused at least one mishap where pilot did not ( coudn't ? ) feather the prop and plane was crashed during take off.

Possibly P.38 is ( also ? ) superior in this sense even in 1/2 scale.
