This was built straight out of the box. With most Skywave/Pitroad, these are straightforward builds with very little to go wrong. I changed the camo especially the colours which I felt were better than the guide or box art. The 2 subs from Tamiya for my money are way too chunky and to be quite honest, I haven't got the skill yet to change those rather thick looking parts. The sea effect was just a piece of MDF laying around and some paint, gel and yeah me being very lazy on this build.
