Take note of the slight error I made. The battery tray is notched to go just one way into the fuselage sides. Therefore make sure you glue the bracing tabs on the correct side. As I found out!
I started with the tail surfaces first. Dry fit, then glue n pin. Used lipos to keep flat whilst gluing the ply to the balsa (the balsa is on the outsides Kevin )
With the fuselage sides sorted I then inserted the battery tray after a few dry fits. I found
I had to apply a little chamfers on the tray tags to get the tray to slide into the fuselage sides. Once happy with the fit I fitted the F1 using epoxy and the lower bracing ply and the initial forward landing bear plate with Aliphatic. I will leave this area open for now so I can easily access the firewall if I decide to fit 3mm spike nuts to secure the motor. After a night of setting I then glued the tail skid plate. The fuselage is starting take shape.
My progress so far in rather small workspace - a utility room (No chance of doing it in the house)
Ailerons were assembled on the glass (originally a cooker splash back) and then spent some hours flying at Cashmoor whilst glue sets.
Next morning, a modification regarding the elevator control wires. Made up a 2mm ply former with two holes for the guide tubes 30 mm apart. Image shows dry fit.
Having lots of motors but none suitable for this project I opted for the Ripmax Quantum II 25C 1000 kv. A light motor capable of 3 or 4 cells. The X plate mounting is a perfect fit to the kits laser cut holes in the firewall.
