The TREX is really a good heli to fly.. the V2 has all the blings and parts that made the heli fly better... it does have some flaws.. but flying it is really worth the price tag.... The Copter X is far one of the cheapest yet satisfying heli to fly... I think most of the locals here has this heli and flies this heli over the TREX.. parts are cheaper but you get the same sensation as flying a TREX.. Its something that is worth having...
