RE: Jamara Spitfire60 ARTF
All the joints are well glued and fit accurately together.
One point of minor concrn for me is the firewall supports (arrowed) which do not run the full length of the fuz. sides. Imo, it would be prudent to reinforce this area with fibreglass or triangular stock for safety.
The substantial ply wing bolt plate will offer a secure wing fixing!
