Totally agree Mike, it is a new experience building something and having others doing the same thing at the same time. I really look forward to the updates on the various threads going on at the moment.
I tried my Riva in the bath by the way to assess the waterline situation. Even weighed up with the all the fixtures and fittings temporarily taped in position, and the RC equip and batteries fully on board, it still sits a bit too high at the stern and the bow is too low. Fortunately a little ballast positioned right over the rudders 'rotates' the boat back to the correct waterline. Meanwhile I have a split along the bottom of the hull V, I think from the water penetrating, but it could also be owing to the central heating. Not a disaster as it will be painted eventually, but these teething problems keep occurring.
I also had a real annoyance with my RC, a glitch that had the whole system shut down on me for no reason during testing - turned out to be a faulty switch for the receiver batteries - it was really tricky to get to as I'd buried it inside the hull before planking.
