I fly a VQ T-6 with retracts. Satruday the left retract mechanism failed on takeoff. I E-mailed Tomas at VQ and received a reply Monday AM. Pretty fast huh? Not only speedy but a replacement part is on it's way at no cost for the part. Shipping and handeling is the only cost to me. I think that is great customer service and just have to comment on it..Cliff
