WOW...I thought it was an isolated incident, but this makes me wonder....
At the Bong NSL, I bought an J500, and the liner wouldn't go in. Sanded a fair amount...still, not even close. So I took it to Wildman, he grabbed another Rouse 720 casing...it went in FINE, but the threads were damaged (new casing)!!
Back to Tim, ANOTHER new casing, 3rd time was a charm! Now, I HAD used the original casing for my Level 2 cert flight...I forget if it was tight or not. But bottom line, the fact that tries # 2 & 3 went in FINE shows there IS a Q.C. issue (or issues, as the one w/bad threads on BOTH ends showed) w/Rouse casings...at least w/the 38/720!!
