Haven't been over 10,000 but had to do a rate of climb test for the test program.
for interest, here are the results - I wouldn't claim my timing and my holding exactly to 65kts to be all that accurate, but it gives you the general idea!
cheers

I'v been to 8000 feet with 52 horse power.
Ross, I suspect the altitude in your table are from the altimiter and not corrected for density altitude? Here's your climb points on the graph I made during phase one flight testing. Classic 4 at 760 pounds gross weight and 52 horse power Rotax 503.

I could have gone higher, but I was getting cold.

Hey Tom, those are pretty impressive figures for 52hp! It must be a very efficient combination.
