The K21 seems to climb as well as anything on a winch

only a K8 will beat it.

I agree although last weekend it was so windy the K8 was just getting
blown about all over the place and in the hands of several pilots,
including our DCFI, was only getting 1,500', compared to 1,900-2,000'
for the K21 (assuming the weak link didn't break on the way up). In
calmer conditions the 8 usually has the edge.

What does Lasham teach on stick position for the 21 during launch?

We have a couple of DG1000s and they don't climb quite
as well. If you pull the stick well back, a sort of
pitching motion seems to set in as though the elevator
is stalling.

I had that in a K13 once - it's definitely the tailplane stalling.
Quite an interesting experience.
