Gosh, I see a TBD on the front cover of Feb`s issue. Very nice.
Built mine and wrote about it on this very thread years ago not that anyone will remember! . They all look similar, funnels mostly give the difference. I made mine a "generic" TBD with several funnels but what the heck.
I also built it to be quicker than the TB of a similar vintage circa 1890`s ish wot I built years ago. The issue was keeping the boat flat at speed, and this was achieved by having virtually no cut-up at the rear. Stability was assured by a steel keel stuck under the boat and large fixed stabiliser fins in the centre. They are (or were, perhaps) horribly thin for the length, and I didn't wish to make it too fat hence the keel which is a strip of 1/4 inch thick steel, an inch wide by a foot or so long, as I happened to have this handy (as you do).
Mine is very fast but only uses a speed 480, s35 two blade prop all on a 7.2V Nimh stick. You can see the turtle back bow in action as the thing is very wet forrard due to the low freeboard, and tends to cut through waves rather than go over them !!
Both this craft and the TB steer almost as well backwards as they do forwards…perhaps I over did the rudders??
