I am a 360 builder and have found the same thing,  Haven’t had an issue with hardware.  Did have issues with cowling and header tank.  Now I am having an issue with the exhaust.  However I contacted Aviation Exhaust, after speaking with Vetterman’s (another RV specialist) and I am making progress now.

My kit number is 52 It was originally purchased in 92,  I purchased it in 2006 after 2 other owners.

 

I was wondering how many 360s are still out there that have not been completed?

 

I opted for the 360 in this plane, but sometimes think I may have made a mistake for what I plan to use the plane for.  I plan to make many cross country flights.  I was looking for economy and I am sure I will get it with the  360, however I do not know if a 320 would have made more sense.  In the upgrade I had to get the extended mount, which in turn led to extending the cowling, moving the CG etc.

 

If  the surfaces are straight, true and clean, then the 320 will cruise at just a little less than the 360 on a lot less fuel, if what I read is correct.  Sometimes I wonder if I needed to do the KISS thing and just go with a 320 and the basics, and put the money into optimizing the basics.  Any comments
