Thanks for all the comments, I do plan to take it easy to get use to the aircraft before I try anything stupid.

I've also installed a pull-pull rudder, shoudl let me do a knife edge loop with a YS91.
I thought that it would be finished by now, but I've still got things to do. It always take ages just putting those finishing touches on. I was hoping that it would be ready for the weekend but I don't want to rush it and get something wrong, so I guess that it will be ready when it's ready.
Here are some pics so far
