Yep - 25mm for a big twin. Likely more like 50mm for the smaller heads of the quad. I think the drop of the aluminum quad headers after the "Y" is around 70-80mm so should be easy to make up some little SS stubs that have a rise in them to get the drop back up to where it needs to be.

Super easy.

Do the 190 justice Dale, LOL You don't see people sticking a quality Honda or Toyota motor in a Chevy or Ford.

Game on, LOL.

Yes, it was for the big 210 I was going to use for a bit, somewhere between 25 and 50.

As for headers, just cut the aluminum headers off below the "Y" and fab up new 28mm SS headers extensions in whatever configuration/drop/rise you need and attach to the aluminum "Y" with a teflon coupler - you can get around any wingtube/LG interference issues this way.

I can help you fab up those 28mm SS stubs whenever you are ready. Curves, bends, straights, even flex peices... anything goes and sky is the limits. Just takes a couple hours to fab up whatever you need.

The 190 in the Suhkoi is the ultimate in airplane packages. Throwing it in a wooden ARF just seems wrong Very 1960's

LOL, just trying to use the "EM hype engine"....but as usual it was non hype!

Oh? Sure don't see the so called Honda/Toyota quality where the going is tough. Anyone can build a "granny pavement runner" and have it last!
