Hey Ramon(tug) - This might interest you. I too built the 1/8 scale Atlas Van Lines. Although yours is a Newton, Mine is a Dumas Kit.
I lightened the build where I could, cause Dumas is notorious for Tank like structures and a little heavy.
I also am running the OPS .60 engine.
Dont blow that engine. Youll have a heck of a time getting parts for it. As I have Searched on this forum as well as others for them. Found a couple of chaps with parts, one was in Norway of all places. These people helped out a lot with my parts search.. I have exactly enough parts to rebuild it 2 times and then it is gone. So the engine is just waiting for a new .67 Mac or something to take it's place.
Boat came out too 10 1/4 lbs.
You have a lot of gluing to go and that epoxy adds more weight especially the step when you coat the inside of the boat and coat the bottom of the top deck before placement.
1/8 scale Hydro Hardware was one of my thread names.

Edit: Forgot too mention, Make sure your using a Jig. The jig I built is very strong!! If you do not use a Jig, It will not be straight and cause you some problems later on.
