Daniel,
Welcome to RCU. Unfortunately I'm not sure how much help you'll get; I've only seen one guy from France on here that I can remember, and that was a while ago.

I did a search for those planes because I had not heard of either one. Biplanes are not usually a good choice for a beginner, and the Vortex looks like an Aerobird clone. EXCEPT! it only has an "on/off" for the motor. You'd be much better off with a proportional throttle.

Try doing a search for Aerobird Challenger or use this link: http://www.hangar14.com/product.asp?...epartmentID=10

It's a bit more money, but has a proportional throttle which is really much better.

Having said all this, the problem with these planes is that the radio equipment is on a frequency that's meant for toys, and can NOT be used with other aircraft later.

Don't be tempted to buy anything less than 3 channels, or pay less than about $125 to $150 (US dollars), because you will end up with something that will fly poorly, if it flys at all. (Sorry I don't have an exchange rate.)

If you're serious about getting into this, you will save money in the long run by finding a local RC club and going there to talk with people. If you were in the US I could set you up with links to help find a club.

Good luck, and have fun.
