Well????

Depends on if the blade/rotor mechanism can take it but in theory yes, you should be able to.

It might fall off but it won't take off. The blades need to be spinning not the chopper itself, also if there isn't a pitch (angle) on the blades then it won't. Toy helicopters usually have a flat pitch, therefor no matter how fast it spins round, it'll stay in the same spot and not go up.

Another factor is the weight of the helicopter and the lift needed to be created by the speed of the blades spinning round. A record player simply hasn't got enough. If you had a record player that plays at 1000rpm, then we might be talking :))

Back when we used to have more than two army helicopters!

Yep, '89-'95 the 'Golden Years' :)) now all the choppers are knackered, with the Lynx being nicknamed the 'flying coffin' :shock:

i dont get this discussion so im just not gonna get involved

I am gonna leave this thread now cause when I read "Imagine I've got a very small chopper" posted by Dave...I thought he is talking about something else entirely...very misleading to say the least...

Wow never noticed that :cool:
