Hi Adam,
I have been building an Atlas van Lines off and on alongside my Huntsman. I wasn't going to comment on it until that was finished as I didn't want to seem as if I was running before walking but you've sort of pre-empted that thought.
I will be very interested in your build and your thoughts as you go along. Hydro's are definitely my intended route but I'm only just back in the game after a long thirty year layoff. But it
is what I'm most interested in.
Like you I am scratch building and have used the free downloadable plan off the Astec Models website. I have needed to concentrate on the Huntsman but this is now complete ready for paint so I shall be able to get back on it very soon. I don't have a latest stage pic but this is close
Currently it has the radio box fitted, fuel tanks plumbed in and the hardware fitted.
I have had a post on RC unlimited and had some very helpful advice from one 'Hydro junkie'
The engine is an OPS60 - what make of engine are you going to use?
I wish you luck with yours - keep those pics coming
Best Regards - Ramon
