As you are in Thailand go and see Siam InterHobby. The owner is a New Zealand guy and he can give you lots of honest help and advice. They have plenty of kits to choose from with nearly all fully built on display so you can really see what they are like. He wont try to sell you anything he doesnt think is suitable for you and usually if he has time will build it install all the gear and help you with your first flight or arrange some training for you. Try this company they are good.
