I have one with maybe 500-700 flights on it. I don't find it particularly hard to land but I've dorked it on landing a few times. It really bites hard if you stall it however. It will flip backwards and drop like a leaf.

Personally i don't think a belly pan speed brake underneath is needed. I do however find that canting the rudders in helps landing on a calm day. You also needed to be careful on the dorsal speed brake linkage to have good mechanical leverage.

I have a p-60 on it. It is not that fast but looks fast because it is small. I also cut a couple of inches of the vertical stabs because I thought they looked funny. Did I mention it is small? Good eye test.
