    Ok....I lied. The language was a bit stronger...

    My little Deep Quest was due a maiden voyage tomorrow, so off came the clear perspex r/c box lid, batteries charged, everything checked over, and the lid bolted back on. Through the centre of the lid is a length of threaded rod which goes up through the top deck and secures the two decks together...you know what's coming, don't you? I put the top on, tightened up the securing nut....and heard a 'crack'.

    The results are shown below.

    New lid is under construction, this time made from 4mm Lexan (thanks to Andy(tattooed))

    Very nice, Richard.

    You will find it just a little more flexible than Perpsex but much tougher.

    I don't think this will break David...it's much easier to work with too. Instead of cutting with a saw, I just scribed it with a sharp modellers knife and snapped it off, exactly the same as you would with styrene.

    I just need to round the edges off now and we're done.

    I'd ordered a replacement motor for the Deep Quest as the one that I'd installed didn't seem to have much in the way of revs..the motor arrived this morning, so I thought I'd install it today...a simple five minute job, you'd think? That's what I thought...how wrong can you be.

    To start with, the new motor had different sized screws to hold it in the mount...then I discovered that the new mounting plate wouldn't fit in the gap where the old one was, so out it all had to come. That meant removing the radio box, which wasn't really designed to be removed. I managed to remove it ok, after removing the prop shaft, which meant removing the steering nozzle, then the new mount and motor were fitted. Then I discovered that the motor didn't line up with the prop shaft, the coupling wasn't long enough either...so, I made up a new coupling. Then I find that the motor shaft is a touch bigger in diameter that the old one, which meant a trip down to my local tame engineer to have the coupling modified to suit.

    Back home, I started reassembling everything...dead easy job, you'd think? Wrong....

    Somehow I managed to drop one of the motor fixing screws, which after searching everywhere on the floor remained AWOL...no problem, got plenty of those, so in goes a new screw and I reassemble everything, refit the radio box, and then came the test of the new motor. I switch everything on...the motor spins a millionth of a revolution and jams solid, which in turn blows the esc...

    Guess where the missing screw was? Yep...inside the motor. Another new motor needed and a new esc needed...


    Gosh and bother it, I said...

    Half the time I spend building things, I spend trying to find things I dropped on the floor.

    The strange thing also is that when I cleared the workshop recently, I found very few long lost bits.

    It is like the "odd sock in the wash" mystery!

    It's a mystery to be sure, David...I manage to drop nuts, bolts, bits of wire, styrene bits, yet when I take the hoover for a walk (my building room is my bedroom, so I tend to hoover at least three times a week) these long lost bits and bobs never seem to reappear...and I never seem to tread on anything. Most strange....

    I think that they disappear into hyperspace and end up in someone elses workshop (or motor!)

    @Richard,
    It was a really BAD LUCK,but what date it was?....Maybe 13th or a black Kat was in Your way a day before?... who knwose?....anny was is sad because is necessary to invest into another motor and esd and in the end of it the cost for the Sub is +30% more for Noting!.

    Marius, I hate cats!! Black cats, white cats...all cats!

    Anyway, the Deep Quest is now reassembled, I decided to fit a new Robbe/Futaba rx (just in case) and I'm just waiting for payday to get a replacement esc. (thanks to Paul Cook for the crystal)

    I suppose I should finish painting the boat...but she can have her maiden voyage first, I think.

    I did stick it under the hull with double sided tape, just too see what it looked like...when I put it in the bath, the whole boat just stood on it's nose.

    Class that as a failure?
