Not boat related but Great Modelling
« on: January 12, 2009, 09:14:17 am »

How good is this



Home-made B-29 bomber.........Wow! This is cool. This aircraft runs on four Chainsaw motors.


You can just imagine how much time, effort, skill and money these guys have put into this thing.

Go on the site below, to see the video.

Yes TT, it certainly adds to the realism of the display.

I wouldn't be too happy about leaning over the props when starting the motors, but then I like my head fixed to my neck.

Oh I disagree!   OK not scale like at all but what a model and what a display!
Having spent many a cold hour with my mate Bradders down the flying field, to see someone enjoying flying a model, like the
guy in the video, is a real joy. Scale model flying is a real skill but can be pretty boring to watch...... If you went to a model
show and saw that display, you be happy that you got value for money that  day!

Can someone explain to me how the builders of these things manage to keep the fuel flow to the engine when upside down and performing stunts?

Sealed tanks with 'clunk' weights and positive pressure form the exhaust or manifold.

A heavy 'Clunk', preferably with a filter in it, lies in the end of the tank on a legnth of thin walled silicon tubing, which can move around as the aeroplane / boat pitches and rolls.

Same system is used in our IC model boats.

Gas planes and boats use Tygon tubing, and thick walled tanks which are fuelproof.

Note most tanks have three outlet tubes, one of which is capped off while the model is running, and taken off for filling, when the tank fills, the excess squirts out the bung tube instead of into the silencer

These engines all run on petrol (gasoline) and are all equipped with Walbro carburetors which have a built in pump. Very reliable fuel feed.

Actually, it is just a priming bulb for starting the engine and serves no purpose while the engine is running. Only the base model Walbro crabs have them, bored crabs don't.

Never seen a bored CRAB.  Do they walk forwards instead of sideways to break the monotony. ?   :D ;) :o

Everyone calls them carbs and Bill in his usual ways wasn't being payed so he spelt it wrong.  I thought it was rather good. ;)
