I own a Blade CX2 and I know that in the next 6 months or so I will want to upgrade to a Belt CP. But, I do plan on getting a sim before then.

The question is what option would suit me better in learning to fly the Belt CP? (not considering price)

1. Purchasing the $20+12$ shipping ESky flight sim on ebay (or stores) that comes with the 4ch controller.
2. Purchasing a $40-$50 ek2-0406a or ek2-0406 (is there a real difference?) from ebay and then buying the sim cable for another $12 - this is the radio from the Belt CP / HBK2.

I would use it with FMS and maybe purchase Real Flight (it seems there are mixed reviews on FMS)

I'm also tired of busting parts on my Blade CX2 (small rooms with lots of things to crash into) it doesn't help that i'm extremely agreesive on flying around. I was lifting off, hovering, and circling the room on my 3rd charge. On the 5th charge I busted both bottom blades along with the lower head - I clipped the edge of a door opening.

Is there any advantage to having 6 channels in the sim?

Thanks in advance guys - this forum has very very helpful for new pilots!
