One day I will try one of these ...

The engine was located amidships and the prop drive shaft ran right between the pilots legs.  The nose was all gun.  The access to the cockpit was through a door that I always thought unique.
There are kits and plans available.

Hoo friend, now that you mention it, I'm learning, I never imagined that the engine was in the middle of the fuselage and that the transmission ran between the legs of the pilots !, go design! I also see the weapons in the nose . ... Thanks for contributing with that information, it is likely that many have not noticed those details, or will I be the only one !?
Yes planes are available, I like the lines of the plane, in the future I would do it in balsa wood.
Your plastic model is very beautiful!
Thanks again!

I hope that you do one in balsa Mauricio, you do such beautiful work. The plastic models flew badly.

Yes, mid engine.  Just look at those exhaust manifolds. They had a cannon that shot right through the spinner.



White ones were called "Day Fighters"

Many plans to choose from here: https://outerzone.co.uk/search/results.asp?keyword=P-39

Speaking of mid-engine layouts, here is an interesting one:

Mauricio there is an engine that will be authentic for your Airacobra if you desire.  

This one is a Testors .049 "pipe bomb" engine out of a Testors BD-5 pusher but could be adapted.  Probably only suitable for control line though, and I know you love R/C.  Not any interior room left for electronics, and with balsa could be messy.  

Still I would love to see a model made with one.  

Also love the Wen Mac 'Cobras.  Here's the mock up of it's nose cannon at the United States Air Force Museum.
Sorry for the slightly blurred focus.

A member here built one for the Reed Speed contest a couple of years ago, even including a mid-engined Cox. Neat looking model but we never got to see if it actually flew. Can't find where it is on the forum to get you a picture.

It was RKflyer (Richard Kennedy) who built that model. It's quite impressive with it's scale-like mid-engine!!!

Thanks for remembering Roddie.  That's the one I meant.  Wonder what happened to it?
There were lots of really nice planes made for the Reed Speed comp, but not a lot of them made it into the air.
(Should we comment about the nose-art? )

well YES! I think going for a realistic model is a thing of beauty.

thank you all for so much information!
It is noteworthy that aeromodelista who carried out the model with the Cox .049 in the center of the fuselage, had never seen anything like that.
I never cease to amaze myself with the creativity of many people that really is to admire.

Bob: what a beautiful collection he has a friend; Thank you very much for your concept about my constructions, yes, I like the RC, although I did some UC years ago, I have several UC models on my shelf, but I can not enjoy them, I get dizzy in an incredible way and I came to decompensate in a way that I never He passed.
I enjoyed UC a lot when I was between 13 and 15 years old, now with 46, I have really tried and decompensated too much, but I want to fly back to UC ... will it be a lack of habit?

Marleysky: thanks for the link, I had seen several plans, the moment I decided, I'll see what I'm going for, thank you friend!

KariFS: that design looks AWESOME friend! ... is to take it into account!
Thank you!

Kim: The photos are great and thanks to them I can understand how it worked, it's incredible !! ... what a design, what "lots" of mechanisms are there in play! ... without words!

Oldenginerod: Thanks for mentioning that memory! Roddie has rescued him!

Roddie: Thanks for bringing those photos, I'm really impressed, I never would have imagined: the Cox engine installed there, Congratulations to the author!

Well there is some more things I didn't know lol , i remember Richards entre , very fine looking aircraft.....
