Topflite P-40 Landing gear
Fourstar
The Gear in the TF P-40 is very weak (built 2 of them) You need to use a Ply Doubler at least 1/4" thick on the inboard side of both gear ribs so you have a good strong mount for the gear. The Gear blocks simply glue down top the 1/4" ply doublers. makes for a very strong gear without a lot of weight. otherwise the gear will easily pull out.
Good luck it is a decent flying airplane
