Stay away from the Sig Cub!!! I bought my father that kit and it was a nightmare to assemble. Ive built a few kits before but this was a monster. The plans, kit, and instructions are fairly old and not for a novice. There are several "oversights" in the instructions that forget to mention critical building steps. There are several references on the net in regard to those. Other than needing a bit more power than recommended it flies great. You have been warned......
