RE: big stick 40 arf
if you can, I'd highly recommend over powering your stik. Then you can experiment with hovering, etc. I'm using a OS 95ax in my Great Planes 60 sized stik and it's the most fun one can have this side of the law. I recently stalled and crashed it by flying too low and slow. Thought about buying a different model but I just couldn't stand not having a stik, so I ordered a new fuse and it's all back together.
Here's a pic of the 95AX.
EDIT: there's also a known weak spot on both sides of the fuse just in front of the horizontal stab. You'll know it's fractured if there's any flex in the fuse just in front of the tail area. If you can, before gluing the vertical stab, take a couple popsicle sticks and reinforce the area inside the fuse.
