Thanks, gents!
Vickers - Regarding the cowling - Yes, I also read a lot about this before starting the kit. I therefore approached this part of the build from a different direction to those shown in the instructions. Firstly, once engine was built, I snapped it into place directly onto the completed cowling part. Engine with fitted cowling was then attached to the engine bay and glued (firmly) in place. Front radiator (after painting) was fitted and carefully matched to engine/cowling/sides and glued in place when all matched up. I therefore had the benefit of others experience and this 'fix' worked (and fitted perfectly) assembled in this manner.
One other point on construction - rudder and elevators required pinning (with metal wire) as there is nothing really to attach these parts to. Assembling in this manner has resulted in a really strong attachment in these areas.
Upper colour was my own mix of dark olive and mud brown. Undersides mix of silk matt beige and light grey.
