Today I recieved my set of Spring Air's 100 Series 116 85 degree 3/16" strut mains and was not disapointed. I noticed a (new to me) Control valve/Filler valve and posted a picture here along with the retracts as recieved from Spring Air.

I was all ready to bolt them new Spring Airs in place and deceided to first "have another look for any flaws on the Tiger Tails glass,foam and Balsa air frame prior to final sanding / finishing>>> and was not disapointed--
