This is just one of those things that's just plain cool!

I really can't wait to see it going for real out side.

Top marks Tom, whoever did the skirt made an excellent job of it, they are incredibly difficult to do, and are the secret to making a hovercraft perform properly. :thumbup:

Hey folks,

A fairly big update on the hovercraft, I picked it up from Dover and got it home with the help of HS1 and virgin trains (had afew intresting looks carrying it from St Pancras to Euston and through Manchester!). First test showed the lift fan was doing the job and it was hovering well on 3s. The thrust however was lacking, it moved ok on a flat surface but didn't have the omph to make quick course corrections, struggled over rough transitions and didn't respond well to steering. Also I was getting a fair bit of vibration through the coupler (which was solid) and the drive shaft.

First item on the agenda was a new thrust motor as the existing one couldn't updated to 3s. Whilst I was at it I figured I would get bigger lift motor. Mated to these are two 80a fan cooled esc.

New vs old.

Yet to run it for any length of time so we will see how run times are. Currently using 2 3s 5ah lipos, one for lift and one for thrust. Should the lift motor be drain the battery too quickly I have another pack which I can add to bring it upto 10ah.

Here's a quick video of it with new motive power

I stripped out the old drive shaft and coupler and got a new one made to the correct size. Using the solid coupler to get the alignment right before I glued everything in, then using a a coupler with a rubber insert to reduce vibration.

New lift motor installed

Unfortunately I'm still a piss poor pilot and had a little accident involving going sideways into next doors car :(

But she's now back together and ready for an inaugural trip on the lake.

I wish I had thought of that when I built mine, I never realised fitting a washing machine under the skirts would keep them clean! :haha:
