Older units?

The CX2 is not even 2 months old, I'm not sure how much "older" or how many newer version 4-n-1's could possibly be released yet.

Also, a CX 4-n-1 will not operate a CX2, the 2 runs on the spektrum radio. He would have had to swap his whole setup, and I know he is using stock equipment.

I'm not saying don't do it - I'm just saying that there are risks that may be associated, as with any modification.

BTW - Good guide so far!
