Hello everyone,
I came across this picture on ebay and wondered about the best way to do this. It would be a great engine for a P39 or P63 King Cobra. Has anyone seen a solution like this before?

Me..I made something similar about 12 years ago for a P39 racer using a 150 four stroke..Mine was made from solid aluminum, not bolted together...still have the piece around her somethere...Way too heavy, even though it was milled out on the sides and bottom...
There's another way..
I made a 10" long extension for a 3W 70 twin to be used in a Nemesis F1 scale racer..
Threaded an aluminum tube to the front of the crankcase, made a long shaft that screwed onto the crank, put a bearing in the end of the tube..Worked fine, the engine wasn't quite strong enough to win....

Ralph,
The tube idea sounds like a good solution. I still think that the fusalage would nedd to be nice and stiff for support.

Looks like it could be good for any skinny pointy nosed airplane. You know, a flying version of Lindsey Lohan. I hadn't yet run across an engine with a shaft that long before. What is it out of?

Matt,
I think that it was custom made for a P39 Aircobra. Not sure how well it worked. Thought that it might cause activity int he forum. Things have been slow latley.

Ill have to keep my cheepo digital camera with me.Theres a guy at my field that showed up last month with a warbird,not sure what it was because it was only the fuse but he had a quadra 35 in the cockpit and a long hub that went to a bearing on the firewall.No support in the middle.Had one of those little squared like mufflers from jtec with the hose running out the bottom.
