saramos makes a good point. I recently had to deadstick my 4* 40 in some corn - my only choice. The gear block snapped cleanly off. I glued it back on, repaired a couple of small holes in some monocote and was back in the air. If I had strengthened the gear area I may have had a lot more damage - or no damage at all, but all things considered I'll take my chances with the gear as it is.
