RV14 Exhaust hanger
I am noticing a bit of vibration in the tunnel and side skins of the RV14. The aircraft is also a bit louder in the cockpit then I am used to.
When I installed the aft exhaust pipe hanger I wondered why such a solid metal arrangement had been used.
In the following picture you can see the stock hanger on the right side and the "rubber" isolator that I fabricated on the left. I made the hanger from automotive exhaust pipe hanger material. Both sides now have the modified hangars and I will test fly it tomorrow. I have never seen, on any equipment, such a rigid exhaust pipe hanger as was supplied by Vans' for the RV14. The new set up securely holds the pipe and I can not help but think it will help with both vibration and sound. I will report back
Finally something on the RV14 that looks like it was made by a homebuilder;-)
