DG-1000 undercarriage collapses and inadvertent extensions ?

Happened to me in a 505, & I'm a long-armed gear slammer.

Our club in the UK has two DG1000s with the two wheel
tail dragger configuration. We have had numerous undercarriage
collapses on landing, but as far as I know no unwanted
extentions in flight.

The problem seems to be that a great deal of force
is required to get the gear over-centre and that the
lever in the front cockpit has a very long throw. People
with short arms, or who are not very strong have a
real problem getting the wheel to lock down. I personally
find the U/C reasonably OK to operate from the rear
cockpit, but very difficult from the front. And yes
I have had the U/C retract on landing, which was very
embarassing.

The whole thing seems to be very poor from an ergonomic
point of view.

Anyone seen this problem in the 505?

Thanks,
