« on: September 25, 2011, 07:51:25 PM »

Hi Guys

I have started a new model its a 1/16th scale BH7 so its going to be big but bigger is better today i made some headway on the beuancy tanks this needs a skin of ply on top there is a 6mm sheet of ply towards the rear this will be held on by captive nuts and a large brushless out runner will be put in the on with a centrifugal fan over the motor.not much to see at the moment though i will keeep the builg log going though

God were BH&'s noisy.  Used to work in the Captains Office at Daedalus next to the main gate.  You could hear those things when they started off in the Hovercraft Unit hundreds of yards away.  And feel the wind off them.

I assume you have photographed the Hovercraft Museums BH7 to the Nth degree and have all their drawings? I also have something of a soft spot for the old BH7 and plan one as a future project at some time. Will you be steering via the motor? If so, have you figured out how to mount the pylon strongly enough to avoid any embarrassing mechanical failiures?
Good luck with the project :-)

yes i have taken some photos of the museums BH7 as for plans i have got a small scale version that did not work too well so i am scaling the structure up and i have redrawn the super structure as for the pylon i am yet to think of a way to do that but it will be steared for the motor just like the real thing

The good news is, I have no idea how to build that part light enough yet strong enough either!

had a few weeks off but i got back on the model and this is the current progress the plylong and box are made from 4mm lite ply cut on a milling machine there is a large brass rod that runs through the pylon this slides onto the next size down and allows the pylon to move then theres a further section of fixed brass tube in the box the whole unit will be held on by captive nuts to allow the box to be removed to gain access to the fan

Looking good so far. Nice, tidy build. The support for the pylon looks like it should be up to the job!
