thanks for the comments guys, it's very much appreciated.
Had a bit of an issue when i started priming the larger parts on the sprue, during the last coat a load of what looked like grease spots appeared, luckily it turned out to be a dodgy can of paint rather than grease spots which would have been worse case scenario. A quick buff with a sanding sponge and a fresh can of primer and everything is now in primer without any issues.
I've finished the interior framework and made a start on the wood effect paint job
Also done a test fit of fuselage and wing root, all 4 slots on the fuselage needed opening out but no big deal and it's a nice tight fit
I've also made up the lower wing, there's absolutely no strength in the 2 spars on the centre section so have PVA'd 2 stirring sticks to stop it bending too much, they'll also give me something to hold when painting
