Dick,
This Vector was built from a kit. It was built per the plans.
I feel that it would have done this to almost any plane. If the plane lands as a fast rate of speed and then you reach up and grab the landing gear bad things will happen. If the gear block was in the wing it would have ripped out sections of the wing.
The end of this launch pad (I'm calling it a launch pad because I will never land on another one.) had a very sharp tapered drop off, and the grass was trimmed very well to match the height of the pad. So from a distance everything looks level. But if you see it up close you would know right away not to drop your wheels into the space between the pad and the grass. Lesson learned.
I do know of a ARF Vector that was flying off a baseball field and landed on the infield and rolled out to the edge of the outfield grass. About a 2 inch lip was created at the start of the grass. Same thing happened.
I do not know how the ARF's are built, but I do not see how you can beef up that area without adding a lot of weight to the plane.
A new gear block cut and glued it back in place. I don't know but it might be better that it rips out rather then taking more of the plane with it when it does depart the aircraft. If that is the design then I would suggest that you do not make sharp points on the back of the wheel pants.
