Nice build so far. Unfortunately, I don't have the answers on the propellers. I'm new to RC boating as well and will follow your build closely as I have the S boat to build. On the plywood parts, have you sealed those already??
Thanks again for sharing and I eagerly await your next posts.
PS, As far as the props go, can anyone furnish the same info for the Italeri 1/35 scale S Boat?
