Hey Rob, our problems have been the tail box also. The biggest problem is screws vibrating out of the tail box. Mikey suggests you not get locktite on the plastic but its a must to lock tite these units. I did a small test on the plastic locktite does not seem to bother plastic. Also we want to replace the screws in the tail with bolts, washers and lockwashers. Having trouble locating 2mm bolts long enough for this application. Any suggestions on where to get bolts long enough. I can't find anything online. I think for the price we can deal with these issues. Not complaining just want to get it right. Thanks Rob, mike scott, [email protected]
