I've not started building it yet, still some other parts to arrive, etc, but did take a few pics of the hull.  Unfortunately I can't find the cable to transfer the pics from the camera to the laptop LOL. ::)  Instead, here's a pic of the battery pack that was in the email confirmation.

It has 8 LiPol cells at 5000 Mah with a 29.6 v rating.
Smartphone?  Why not use that?

Maybe it's worth getting a replacement USB cable which don't cost that much...  Hope the build's still going ok though.

Thought of that o.c except it's not that easy.  It came with a proprietary USB cable with an odd type of connector at one end, can't find a replacement anywhere - even mfrs don't do it any more as camera is discontinued years ago. :P   

As said earlier, still not started the actual build yet as some parts still to arrive or get...

To all concerned with this thread.  I moved this topic to here ('Radio control projects discussion' under the new board 'Hobbies and pastimes') from 'Off-topic discussion' under 'Blag-it lounge' as it was more suited.

Great idea for a new board category.  Gratz! :)

Hmm, I see the problems.  An obvious solution I see is to get another basic point-and-shoot digital camera but one that takes a standard USB cable, or a mid-spec smartphone with camera and just take some more pics of the build.  Either can be had now for well under £100/$130 in high-street electronics and mobile phone shops. :D

Nice grooves on a nicely pointed hull there. :)  So happens I've built two fast-electrics so hope some of this helps.  Going by your mock-up diagram it looks like you're going for a flat deck which is a good idea as this will afford some down-force on either side of the canopy and so keep the bow down and reduce bobbing.  However you would need to set the edf slightly further back to prevent pushing the bow down tooo much. :o  For a boat that size you'll need at least a 9cm fan with brushless outrunner that has high rpm and min of 12 LiPol cells; ideally 12cm fan with 18 cells.  For the deck use either fibreglass which I think the hull is, or gel coated styrofoam.
Found out from a few retailers, etc, that I should go for a brushless inrunner, not outrunner (sorry for contradict but that's what I've been told...) and that 8 lipo cells should be enough to begin with.

Thanks, and I agree I'll prob have to get another cheapo camera.
