I think raideron is using that combo. He'll chime in here soon. But I think most are using the 13x4W on the 63 to let it rev a bit higher.

You may reinforce the landing block a bit, or wait till it fails, some don't, and then do it. Build it as light as possible. I use carbon fiber pushrods to make it stiff and for precision control. Cut the cowl WAYYYYYYY open on the bottom for good cooling.

Avoid doing the flat spin landing with this plane. It doesn't like it very much.

Thanks
