I have to agree with Don Reid if I understand this thread correctly. My take on it is that the original design has 4 bolts per attach point for a total of 8 per wing side. If this is the way yall (sorry) are doing it, I will YELL hold on! I have been doing the wing attach thing with 4 bolts total per side since I bought mine because the original builder set it up this way. In addition, my spar is carried ALL the way thru the WAFs so that all 4 of my bolts pass thru the WAF AND the spar (WAF spar WAF). The ends of my spars of the stub wing touch the ends of the wing section spars by butting together. I really trust mine, and my DAR agreed that it is the strongest he has seen on a KR2. I have taken my wings off 4 times and will install new AN bolts front and rear for this next install, just on principal.
And if I dont understand it, I hope you understand how mine is anyway, LOL Saw a Robinson R44 giving rides today, WHEW! What a scary sight watching that thing fly in the wind! Colin N96TA
