ps if you look in the cockpit close up you will see part of the compass in the reflection.

Just some more photos. The boat is now finished and ready to run, but as always with these projects it is never finished, is it? I dare say next week/month it will be be slightly different (maybe Improved) we seem to titivate our toys forever, so from that point of view are they ever finished? Unfortunately at the moment the lake is still drained, so later in March will it be available for sailing and then I hope to get some video or stills of it on the water.
I had a problem with one of the motors it was way-out of balance, due to I don't know what. I replaced shaft, bearings and in the end balanced the rotating case. I don't know the history of these motors but the other one ran as sweet as you would expect with no vibration throughout its range, this motor had a horrid vibration at 1/3 to 2/3 throttle, going up and down the range, the top end wasn't to smooth neither. I noticed that the magnets were not evenly spaced on the inside of the rotor so with some epoxy and a drill burr I managed to balance the thing using tye wraps and a springy piece of wood!! The mind boggles!!! I will show show photos how I did it but you can find all about it on U-Tube.
I've had fun building this and a lot of support from readers on this blog and I take this opportunity to say thank you very much indeed for all your comments and advice, it has made this boat what it is because as a newcomer I didn't have to much of a clue about boats (this is my my second scratch build, and about my fifth boat altogether) so wait for the water to come back into the lake and I will sail it and give an update, Thanks again Brian

The dirty deed has been done!! I maiden the Riva this afternoon (17/3/12) with great success. Very pleased with the first few voyages(?) quite quick and very quiet, the water is pouring out at the stern outlets even at low speed, batteries and ESC's run very cool, a problem I worried about because of the low decks and lack of fresh air, the turning circle at speed is not as good as the Fast patrol boat, but low down it is passable, as a early contributor said are the rudders big enough? I will try throws first and then a mix on the Tranny. I am using 45 props and they seem to work so I will give it a watt test then will buy opposite rotating props. Might get 3 blade although the sailing this afternoon it stayed straight at all speeds and acceleration with same way rotating blades so there might not be any advantage in opposite rating props. The inside of the boat came out as dry as it went in after about 3/4 hour running but the outside got a good drenching!! Had a loads of interest from a lot off passerbyes one woman came over and told me what boat was as she had always admired them from a holiday she had in the S.France! And my boats name is the same as hers!! Gloria. That's is always the best bit, when the crowd are pleased. That's it for the time being but I am trying to upload a video my wife took on my phone, she unfortunately has only the use of one eye at the moment so please forgive her (there is a Op coming off v. soon) Good sailing everyone and thank you for your responses and encouragement, Brian ps there are a couple of videos now!

Some more photos from its first outing, The photos were taken by Brent Hopkins of Towcester who has given me his kind permission to use. I think you will agree that these are very good photos considering the camera was new to him. I have run the boat several times now and have found always that one battery is way down (in Volts and percentage left) at the end of the session, so I have ordered a new motor to replace the one that was damaged in the aeroplane crash, this is the one drawing a bigger current. Enjoy the photos ,Brian

Riva water system, hope this Is easier to understand
