Subject: [FlyRotary] firewall to prop flange
after mounting my psru to my renesis engine and onto my klepis mount I measure 39" from flange to firewall. my existing -6A w/ O-320 measures approx. 33". in the back of my mind I remembered 4-5" difference, not 6". I assumed that all the geometry had been calculated when I ordered the engine mount. I currently have 5" between the water pump pulley and the firewall, which is wonderful, but, I don't want my battery(s) in the tail either. am I going to get into weight/balance issues? what dims do other RV's have? kevin
