Its coming along nicely

A few items I see here.... if I may......

get rid of the screw-type hose clamps.

they will eventually cut through the coupler (works like a cheese slicer). And they are heavy. The coupler is not a structural attachment between header and pipe ---- the pipe mount takes care of that.

Just use a 1/8" wide nylon tie wrap on each end of the coupler. Pull them tight. This is mainly to keep the pipe or header from moving around inside of the coupler, and to provide a gas seal so it does not leak.

Glue on the forward tank hatch. You can slide the tank in and out through the wing bulkhead if needed later. Add some 1/4" triangle stock to the upper edges of the fuselage and top side of the firewall, and glue the hatch securely around all four edges. You need the stiffness on the front end with that engine. (of course, remove covering from the suitable glue surfaces)

Very important the the RX be well packed in foam, and does not physically touch the airframe. Looks rather snug back there... perhaps install it up in the main compartment under the wing?

One other item.... seal the aileron hinge gaps (not optional in this case). You may want to seal the elevator gaps too. Use iron on covering, blenderm tape, or even just heavy transparent "scotch tape" works fine. Deflect the surface full up, tuck the seal tape down in the gap.... and afix to the flying surface and control surface.
