Pipe Lagging Hovercraft
« on: September 18, 2009, 06:59:13 pm »


Come up with a ( or publicize an existing )  simple and endurable plan that modellers can 'have a go at' with
bits of stuff already lying around the workshop.  I seem to remember a kit or plan (SLEC?!?!) that was based on
plywood and foam pipe lagging.......

( The Springer tugs were based around parts from RC cars; 540 motor, 7.2 volts & 2 channel radio, you could do the same! )

  Model Boat Mayhem is here to help you promote your endeavours!

  (PS. Step by step build threads are very popular on here!  :-))


This got me thinking, so I started to build myself a pipe lagging airboat. This is so simple to do, I cut a piece of hardboard to size, which I will glass over later, cut some pipe lagging to size and I was away. The motor mounts were from a 13 foot sailplane that I've never actually fitted a motor to. The engine rails are 1/16" ally right angle, the engine bolts directly on.

Not being of the electric persuation, I'm powering it with an old Irvine 15 buggy motor. I was given it some time back and never run it, though it looks as it it's only just been run in, no grime on it anywhere. If you fancy having a go at one, you could power it with an electric motor of about 600 - 700 size. The engine hasn't been run in ages, but it was stored with oil in it, after I cleared it, I stored it with after run oil. I fitted an O.S remote needle, to keep fingers out the prop. This afternoon, I fueled it up, blasted all the oil out with the starter, connecter the glow start and wheeeeee......

Next up is resining the hull and the engine pod, trimming the piping, then building a radio box :-))



Here it is at the moment

Read the first bit Bill ;)

It's made entirely out of bits I got from boxes etc in the loft. I've yet to buy some more resin, soon as I do it'll gor for some trials. It's had some bath trials already but if I don't glass it the wood will fall apart...

Andy having built and ran airboats a few times in the past id suggest angling the prop up a tad so it keeps the nose down,also when running dont let off the throttle to quick or she will flip.I used to make mine from corroplast and used silicone for glue ok2.Mine was powered by an os 46 ,lots of power and fast as  :o but did like to flip if i let off the throttle too quick.Great fun on water snow and ice  :-)),even damp grass hehe.

Andy i see the prop angled so the thrust is aiming up which will cause the bows to lift ok2 you want the nosecone pointing up in the air so the prop blast is aimed down to push the bow down ,2% angle is enough.Theres a good airboat section on rcu if you wanna check it out :-)).

Andy

How are you going to make this airboat into a hovercraft?
