Pics showing the tank floor and the servo tray mounting rails. There is no provision in the kit for installation so it all down to experience here.
14. Engine

View Details
Original engine was going to be the NGH 38 4S, but this was just too big. Opted for the NGS 25 2s but it still stuck out a bit too far. What I did was recess the engine 6mm onto a false F1.
This works well, I have the engine almost upright, and an easy run for the throttle connection, and the exhaust will exit downwards.
13. Fuselage tanks and hardware
View Details
View Details
Strut fixings and tank installation. 2 Tanks one for petrol and the other for smoke oil. Went a bit mad with the Gorilla, but is soon popped out, and cleaned the thread with a tap.

Complete sheeting, and capping strips. This was a pain just so boring. Lost concentraion on a few so not as aligned as they could be :-).
11. Wings

Finished aileron / tip. The training edge of both wings have a run of Gorilla glue just a smal bead which expands and gives a really solid trailing edge. Started the centre section sheeting, a section at a time.
10. Ailerons

View Details
Ailerons built over plan, and offered up to the wings. As can be seen thay don't quite line up. Solution here was ti simply pack out the Aileron edge to suit, it was then temporarily fixed in place with some Solartext and sanded to tip section.
