I am in the process of putting the finishing touches on a 4.2 meter Rodel ASK 21. The craftsmanship and materials have been some of the best I have seen on the smaller (under 4 meter) ships I have seen. The instructions on mine have left a little to be desired, but with a little patience and imaginiation, it was no real problem. I would not hesitate to buy another one of his kits if the price is right.
