Whats the difference between the blade cx and cx2? If i got a blade cx for $65 and would it be worth it to convert to the cx2? is there major issues with the cx thats why they made a cx2? or should i go the extra mile and get the cx2? i need to know before i buy

The biggest dif is in the radio. 2.4 gHz Spektrum with the CX2 vs 72 mhz FM for the CX. This makes the CX2 a better buy especially if you live in a big city or anywhere radio interference might be a problem. Body styles are a bit different between the two other then the radios. Converting a CX to a CX2 would not be worth the trouble or money as the dif in price is negligible compared to the cost of switching the radio Tx/Rx to the CX.

I've seen the CX-2 in action and frankly, I was impressed for what it is. Rock steady and very maneuverable. We had 28 kids and adults in a ground school and they saw it fly during lunch. I saw a lot of adults' eyes light up and heard one of them say "Christmas!" They liked what they saw and I did too. My heli is the T-rex 600 but the CX 2 looks like a lot of fun indoors. Battery life was quite good according to the owner.

yeah, it probably wouldn't be worth it, because you at looking at 55 for the TX and about 60 to 70 for the 4 in 1, plus the body if that was important to you (not that big of a deal, basically just a different color, red instead of yellow)

The thing with the cx, you may get some interference somehow, but most of us RCer's still fly with the 72mhz systems, so it's not really that big of a deal.
