Google is your friend. Here's what I came up with.

Rx540vz Technigold Tamiya - 7.4-8.4 volts, 14 amps, 19k rpm. That's a touch over 100 watts, so it could power a model around 1-1.5 pounds with a smallish prop.

"Leisure" 05 stock motor- Couldn't find specs, but here's the manufacturer's website with a contact button. http://leisurercmodels.com/

Le mans 240E Kyosho- No amp or watt info, but it's 3846 Kv which makes it way too fast to turn a useful prop without a gearbox. Setting up one might cost you as much as a different motor that's not so hot would.
