Just finished cockpit and engine,made own copper wire springs for tappets,0.3 tube for ignition wires to attach to,and 6 wires poking out of the end.Had to cheat a bit wiring distributors.Had HGW merc III engine set,didnt use it,the little gaskets for exhaust mightve looked good,but bloody hard work for it.Really easy to paint interior the way its laid out,looks like perfect beginners WnWs kit for sure.The metal skin does simplify the way the kit builds up,the end seems always reachable.
