Yep, the groundcache can't find a intersection. I think this problem
occurs without my patch also. To fix it just change groundcache.cxx
around line 312 from this:

if (d*d < reference_vehicle_radius*dot(n, n)) {

to this:

if (d*d < reference_vehicle_radius*reference_vehicle_radius*dot(n, n)) {

I am sending the diff again with the fix for this and the (untested) fix
for the zero-speed problem, just in case someone want to play with it.

I am still trying to figure out why the s76c is shaking. This happens
with other helicopters also, like the R22.
