Hi.. Thanks to all for prompt reply,
I will look for LT 40, NexStar and Alpha 40 as another options.

A friend of mine suggest to go directly on GAS Powered Engine rather than electric. It is more fun and realistic, thus flying electric and engine in an open area will not have the same characteristic.

I choose to buy a RTF because its simply, Ready to have Fun, Cheaper and a Factory Best Product... so what do you think of it? is it true?

Again thank you all.
