33% Extra 260 & DA-85

I am about to re-engine my 33% Wildhare Extra 260 with a DA-85 and install a cannister with the new engine. The engine will be mounted vertical with the head towards the bottom of the aircraft. So it will require a wrap around header, and that is where my question is. What drop will I need in the header?

RE: 33% Extra 260 & DA-85

It depends somewhat on what muffler you choose. If you use a muffler with the inlet centered in the muffler you will probably want a 50mm drop, but honestly it's been like 5 years since I dealt with these planes so it's not easy to remember.

BTW for anybody else who still has one of these I have a new fuselage for a red one, just the fuse, no hatch or canopy or anything else. $300 shipped.
