I'm about done with an ultra stick 40 except for radio gear. There is a ton of posts on here about people reinforcing just about everything you can imagine on this plane. The most common are landing gear block, firewall, tail wheel, verticle fin, wing hold down blocks, and wing dowels. Some of the things make since such as the wing hold down plates and verticle fin. Wouldn't it be better to pop out a landing gear block that rip out the bottom of the fuse or pop out a firewall rather than tear the nose clean off? The only thing I've done was to put tubing over the dowels and put triangular stock on the sides of the verticle fin in front (it did look pretty flimsy there). Why would a tail wheel be a problem? Don't they lift quickly after the plane gains speed? I had planned on just putting a 46 engine in it which is toward the bottom of the recommended size range so it's not like it's going to be overpowered. Do I need to worry about the firewall or tail wheel modification? I won't be flying it for some time since I only recently soloed my avistar but wanted some input on this.
