RE: Brent Good Custom Airframes 50cc Yak 54
The wing tube is 1" carbon fiber and the stab tube is 1/2" carbon fiber. They are both available through Troy built models. The sleeves that you are talking about I am asuming that you mean the sockets. The wing panels come with the sockets installed in the wings. The wings have a plywood captivation rib installed as well 1" from the end of the socket. There are 2 options on how to get the kit. With the wings vaccume bagged and sheeted ready to glue on the leading and trailing edges or with the foam parts just cut. The second option you will have to do the sheeting yourself.
There is no room for cans or a tuned pipe in this plane. I did this to keep the weight down. You could modify the fuse to make room for a tunnel. That would take a lot of work. The front of the fuse is 9 1/2" in diameter. That does not leave a lot of room for a can or pipe.
You are right that I need to put this in the kit building forum. Is there a way to post it in both places or do I just need to put in a link?
If you have any more questions just shout!
