What kind of mounts are you guys running YS's using on the Integral?
I installed a Hyde ARIA. I had a lot of problems with my YS detonating and finally traced it to a broken fuel line in the tank (darn it!) Anyway - I now have it running... but it shakes so bad below 4500 there is not enough clearance for this soft a mount. The header hits the fuse sometimes... it is really bad.
I am having so much grief with this plane let me tell you! Lots of hard lessons learned. My bad tank caused a huge backfire at 1/2 throttle which actuually broke the side of the fuse the header flange hit it so hard.
I haven't even got to fly it yet
Today I installed a new fuel system and it runs great from 4500 - 8500 RPM. Prop is very well balanced. Below 4500 it shakes an insane amount to the point the engine will quit/hit the fuse side etc. There is no question of even being able to run the chin cowl.
On the break in bench with a solid mount it seems just fine - no worse than any other 4-stroke.
I am starting to think in this fuse I should run a more solid mount or go with a built-in nose ring vs the beam integrated one.
Any ideas?
Hi there,
I used to run the ARIA mount with a YS 160DZ on an Extreme Composite OTOP with no issues at all. Now this mount has been installed on Integral with a YS 170DZ, I have not run the engine yet, but I don't think that Integral has less space in front compared to OTOP, so I believe that it will not hit the sides of the cowl. Let's see if it hits then I will probably have to remove the integrated nose ring and use a separate one like you did. What prop did you use? Can you also send a photo of your configuration?

Nikos
