RE: BUILDING A PHOENIX 8
Well welcome Rangerman it is always more fun with a audience.
I am laying out the tank floor and the front gear retract here. I just use a little 30 min epoxy on the pieces with a few spots of thick CA to tack them in while the epoxy sets. After all is good and tested out for the correct position I glassed the parts in with 6oz cloth and some West Systems Epoxy that I make the Fuselages with. They are rock solid now, don't want your front wheel to fall out.
You can see I added a piece of 1/4" ply to the area the wing plugs into because I am adding two 1/4 dowels for the wing to plug in instead of the single wing mount bolt the plan shows. The reason is when I was reviewing the plan I calculated that the front wheel when retracted may need to be notched into the leading edge of the wing. So by adding this ply bulkhead now I have the option of not using the front wing mounting bolt if the front wheel comes to close to it.
