Brief Description:  Torque and cotter pin engine and mount. Starter re

Torqued the engine mount bolts and nuts to between 160 and 190 inch lbs. Most required 2 washers each and one required two plus a thinner washer. Its a balance act between getting the hole in bolt to line up for ctter pin, not be too high on the nut, and not exceed the torque limit. So its plenty of trial and error finding the sweet spot.

Installed the cotter pins in the mount bolts and folded them over

Torqued each of the larger AN7 bolts for mounting engine. Plans say to tighten until the lord mounts bottom out on the inner tube and then torque 450-500 inch lbs. This took longer than the mount did but basicly same method with washers. These are tightened up the bolt and using a wrench I had ground down for fit to hold the nut. Its a tight space. The cotter pins were installed and folded over on one side. The other side will have to wait until I aquire two more cotter pins!

I installed my fabricated starter relay mount. Once installed I realized that I might need a good ground where the diode attaches. So I removed it and then sanded away paint as required and then installed again. Tested continuity at the diode attach point and the airframe. Now the relay has better clearence from the engine lount tube
