Cheers Andy, thanks for the comments.
I look at some dio's and they seem very cluttered, I like to try and keep it to a minimum although Im no expert, this is only my third! I wanted to put a small wheel loader in there to clear the screened earth but though it might be too much, in hindsight it needed it.
The 390 is a cracking model, well worth getting if you have the other 2. The only issue I and others have had with it is the bucket rance. there is a small tab that stops it curling in and tipping all the way, just a case of filing it down but I'm not going to do it.
I would like to show at Burnley but I need to get a bit better at it first!
Need to dust the models down now. If the weather holds tomorrow I might knock another up!
