Default Best Bridi for an OS 75AX

I am want to build a pattern plane over the winter and am leaning to the Dirty Bridi, but read a post that said an OS 61FX would not fit without a lot of mod. I have a .75AX that is looking for a new home, what Bridi (or other) pattern ship kit would be a good choice?

I had the 75ax in an GP Ultra Sport I built last year and had fun with, but due to 'gravity' the plane is toast!

Thanks in advance,
Mike

OS 61 should drop right in with no problem. Jim

How about Killer Kaos, Utter Chaos, or My #1 choice, Direct Connection Ultimate Kaos.
I flew My D.C. Kaos with a Tower 75 in the nose.

Actually the .61 AX does not drop right in. Due to the rear needle valve the engine is just a little too long. But it's not a major ordeal to make it fit. The nose is going to be built up with some blocks anyway, just replace them and size to fit.

Or move the firewall back 1/4" or so as needed, which isn't a bad idea because they turn out nose heavy anyway.

The .75 is probably enough engine to fly one of Bridi's larger designs like the Great Escape or XLT without a pipe. [link=http://www.bridiairplanes.com/hangar/xlt.html]Bluejay[/link] sells the XLT kit.

Thanks for the replies. I forgot the .61FX has the rear needle, and the new FX has the needle at the carb, so there should be a little more room.

I will have to check out the Direct Connection Ultimate Kaos, thanks for the suggestions Ouhozer.
