May 3, 2010: Big Boy, Big Toy
 
Brit, Tony Nijhuis, like a zillion other people, built himself a model airplane.
But his 1/7th model of a B-50 bomber is so big... how big is it?

...it is classed as a light aircraft and had to be tested by the Civil Aviation Authority and requires a certificate to fly it at public shows.

It's not only capable of carrying mini-bombs, it's sneaky quiet.:unsure:

'It's a model of the Boeing B-50 bomber that was used from the 1950s to the 1970s. It's all scratch built and has a wingspan of 19ft. 'It weighs just over 100lb and is powered by four, four kilowatt electric motors and each motor has 24 batteries powering it. The propellers have a 2ft diameter.
It has 96 batteries that power four electric motors which drive the aircraft to 40mph along a 50m runway before it takes off. It can then fly for eight minutes in the air before it has to descend so the batteries can be recharged.


I wonder if having to assemble a crew, and get government permission, takes some of the spontaneity from playing with this toy? ;)

What would propel a man to build that?

SPUCK 05-03-2010 05:10 AM

Quite electrifying.

I'm up in the air on this one.

- Umm... Propellers? 4 of them.

In any case this is a 100 times cooler than the half a boat from the other day.

Building it spanned 2 years, a departure from the norm. I'd rudder it didn't take so long.

All of this punning is putting my head into a tailspin.
I almost split my Buttock Line.

The answer seems plane enough to me.

Clearly he just wants a little lift in his life.

What? No treadmill?

squirell nutkin 05-03-2010 11:57 AM

Well, there goes my plan to build a scale model of Nagasaki.

monster 05-03-2010 12:24 PM

OK that takes care of what my 11yo son is going to be doing for the next two years....

....building a 1/7 size treadmill


Nobody tell Spirit or they might start trying to cram ua all into one of these to further reduce costs.....

Gravdigr 05-03-2010 03:50 PM

Built from scratch?

That means...








Wait for it.....








...he was winging it.:lol2:

Elspode 05-04-2010 08:35 PM

24 batteries...for each motor? And each motor consumes 4k watts? WTF kind of batteries is he using so that the whole plane only weights 80#? Nuclear?

squirell nutkin 05-04-2010 08:45 PM

Lithium and NimH are very light
