Hi Alistair, Have you got any video of running with the lead acid? I cannot make mine perform without nimh's, curremtly flipping betweem 2 x 8.4v 3300 and 2 x 9.6v 4600, planing for about 25 mins. I tried a 12v lead acid, but after 5 mins it was tug boat speed, but would have lasted ages. By X55 prop, does that mean 55mm?
Re window frames, I did a template of paper, then transposed that to plasticcard, stuck the perspex on the frame as window, then stuck it to the boat. I then used small aluminium rivets (very difficult to get!) but dressmakers pins are similar, again glued in through pilot holes. Very time consuming, but look ok, if anything they are a littler big. I painted it in humbrol steel, and buffed it up a bit with a cloth.
Cannot work out how to do the air scoop thing, any ideas here (sorry to piggyback the thread) perhaps alaistair you could start a new thread?
