This build brings back fond memories for me as well! I remember adding mottling with a piece of sponge dipped in Pactra paint. It came out surprisingly well; I was really proud of that one.
IconicAir has just released a Dambuster conversion set!

I agree with the others...
The mount for the cowl flaps and engine is about 1mm too high on this kit. Sawing it off and lowering is easy and requires no sanding and/or rescribing.
Keep paint of the cement point on the framework, Harv - you'll be glad you did. Also, the nose wheel is a PITA to install when they tell you to do it. See if you can't put it in earlier in the build sequence.
