I've never flown a Prop powered twin, but I have built and flown an F-4 Phantom with twin ducted fans and a Kyosho LearJet with twin EDFs.

The Lear probably doesn't really count as flying a twin, because the motors were wire together through one controller and battery. So they always ran together with almost no chance you would have an engine out.

The F-4 Phantom, on the other hand, with ducted fan motors in it was subject to engine outs and in fact that is what caused the demise of mine. There are no assymetrical thrust issues when you lose one motor, but you still need to do everything right. I lost one engine when I throttle up to go around after botching an approach. I thought I did everything I could to save it, but the video of the crash, showed that I made several mistakes. Number one was that I was landing the plane to begin with, because one motor sounded a little sour. I should have gone ahead and landed it hot and let it run off the end of the runway instead of attempting to go around. Number two was that I made my turn away from the runway too quick, before I had built up enough airspeed. The F-4 bleeds off a lot of speed in turns. And finally number three was that I pulled the nose up in the turn, causing it to lose even more speed. And that was the end of that.

So for now, I'll just keep dreaming about my twin turbine powered wish list.

Where I already have my P-38, my next vote is for a ME-262 or possibly a big HE-111. I love that great German WWII twin Technology.

Without a doubt..the DeHavilland Mossie!!!!!!!!!!#1

I guess I shouldn't be really surprised by the Numbers, P38 is running away with the award as our favorite twin engine palne of the war yrs. I am surprised though that the no German planes are making a real shoowing. I always thought the Germans were the more innovative and daring when it came to new designs .

I thought the grizzley might be a candidate to bash out from the Ziroli D18 plans. Any luck finding 3 views? If I had 3 views the Grizzly could jump to the top of the what's next list. I just finished my Wannabe P38 and the next project slot is open

Anyone got pics of this ," Grizzely"? I dont know what it is.

Thanks for the reminder. I have found the three view's for the XA-38. In the early sixties when I was a young kid, I would write to the aircraft mfg's for pics and three view's. That's how I got mine. I'll try to scan the three view's. If not, I'll have to mail you a copy. You should look for a copy of Airpower, Nov. 1978, volume 8, number 6. It has 9 pages of photo's of the XA-38.

Here is some pics of the aircraft.

I think this will make a great r/c model.

Why stop at two or four engine? Do something really wild.....Nakajima G10N1 "Fugaku"
Six engines and designed for germ warfare against the US. No, none actually flew, but there are a few RC models, but not sure of this country.
Germany also had a six engine bomber, that did fly.
Why be normal?......We are in the multi-engine crowd.
Twinman
PS Who me stir something up?? How about pictures!!

Well if you are not going to limit to twins and this one is not WW11 instead post war then few airplanes can even approach the Republic XR-12 Rainbow for shear unadulterated sex appeal. And think of this: not nearly the dysmetry trauma upon the loss of one engine or for that matter not nearly the percentage loss of power.

Good lord, I would hate to think of a dreaded five engine landing!! Just makes me shake thinking of it......Drool!!
Twinman

Okay. let's blame the hijack of the thread on Twinman. Whether or not he started it, he deserves it. Haw.

Chick this one. A real model, really r/c, and it has been flown several times with eight (count them, eight) TeeDee 0.010 engines.

It is the Hughes-Kaiser HK-1. For those who don't know any better, it's more commonly called the "Spruce Goose."

Bill.

you guys are crazy, I mean I heard of car jackings but "thread Jackings?" I can hardly afford a twin engine mishap....a five engine mishap...."OUCH". Those are some eye candy and sure we can blame the JACKING on wingman. How about if we just call it a "driveby?"

"driveby" ???? I like that one!!!

This scan didn't come out too well, but you'll get the idea. flying2bill, pm me with your address and I'll send you a copy of the original which is much better.

XA38 Grizzley

Got your 3 views today, they are good and clear. Wouldn't happen to have any cross sections would ya? Will dig out my D18 plans and see if I can start to figure out a Bash. Now would be a good time to have some CAD experiance. Anybody know some SIMPLE CAD program I can download and try

Found this on Google search.
"Regarding the disposition of the two flying prototypes of the XA-38, they were scrapped after there was no further interest in them by the military. There is little information still in existance about these birds, but some of what exist is held by the "Kansas Aviation Museum" at McConnell AFB in Wichita, Kansas. They have a great arcive facility there."
Twinman

I'm glad I could help. No, I haven't seen any cross sections available. I hope you can figure out how to modify the D-18 plans. I've always wanted to build one.

Wayne

I am learning to use CorelDraw 12 while in the progress of designing my own twin-it does seem like a nice drawing program. The more I learn how to use it, the more I like it.

I have a friend here in my local club who has done a couple of kits for sale from scratch that has stepped up and offered assistance. he also has a laser cutter friend who will help in cutting a kit once we get it designed. I have the 3 views plus I have found NACA numbers for the wings and most important have decided on the nose art, a bit of a stretch since as far I can tell from the available pictures neither xa38 had any art, but seeing as I will have to fudge cross sections, taking liberties with the nose art won't be too big a crime, besides it is MY plane and I don't compete in scale.

That "nose art" is perfect for your project. Keep giving updates as you go.

Hi Bill

How is the Grizzly project coming? If your friend is going to make some kits, I may be interested.

Keep us updated,


Wayne Cook

wow , this thread lives on...............
