I didn't say exactly that, but what I said might be interpreted as that. I found the lateral strength of the robart gear to be very good and didn't think that there was much of a chance for them to bend side to side or twist and let the wheels contact the pants, but I did find the spring force of the struts weak enough that I suspected they would bottom out on a hard landing. By the sound of it, I think that the video posted in my telescoping pants thread shows an actual bottoming out of the struts on the hardest touch and go so as to prove my suspicions.

With Robart struts installed, I measure a distance of 1, 7/16" from the bottom of the pants to the bottom of the stock foam wheel (this is a "stock" measurement since I didn't change this distance when I modified the pants to telescope with the struts). With my telescoping pants, this distance decreases to 1" under the force needed to bottom out the springs in the strut. This means that the foam wheels compress about 1/2" under this force. The struts themselves compress about 15/16". 1/2" + 15/16"= 1,7/16". So, if the pants do not telescope with the struts, they will contact Terra firma when the struts bottom out. These measurements were taken by pressing a pine 2x4 against the wheel of my GB. If the landing surface is more compressible than the weakest link in this test (the spring force of the struts--based on the largest compression distance under equal force), you can expect less clearance under equal force. Thus you might interpret my statements as saying "they (Robart struts) make things worse if you fly off of grass."
