Per Tony F's Du-Bro tank installation, I covered over the hole in the firewall (1/64 ply) and drilled new holes above the engine mount for the fuel lines.

Nose gear blocks epoxied in place per manual. 30 minute epoxy used here. The manual did not specify the orientation of the blocks. I oriented them such that the nose gear unit would be at the lowest value. I hope that is correct, it aint coming out.

Another picture shows the actual level at which the tanks will sit in the nose. Still way high, but an improvement over the stock tank setup.

Time to glue on the stabilizers. Done per manual. Use lots of epoxy.

Next the rudder and elevator servos and linkages installed per the manual, and dialed in to the specifications given in the manual.
