RE: Sig Komander??
See my remarks on the gear reinforcement in the other Kommander thread. Great, durable plane - served me well with a K&B 40. The wing/gear mounting blocks can be easily reinforced by drilling a 1/4" hole through the wing to block, epoxy the dowl in place and sand/fill smooth. You may have to cut a groove through the dowl for the gear mounting. Epoxy with micro-balloons will do the trick.
