Your Brad R. well well well.
I think MB Planes is trying to resolve any and all issues with their product. Jsilver and I may have received odd ball kits, we seem to be the only 2 that are commenting and or weighed a plywood version of this kit. We'll have to stay tuned to see what they come up with. I think Ken was referring to the differrence in weight of the servos, this was only one of the topics touched on as far as weight reduction ideas. As far as the prop goes the blade on the K series is fatter past the perimeter of the cowl, I picked up an 18-6 for my quadra 35 today and it is a big ole fatty.
