I believe that 6" is correct. I got mine from NvAero, Steve Glover. It has a built in stop and has never failed me. You can go to www.nvaero.com or write to info at nvaero.com or call 1.800.515.4811
At one time, I knew the brand of that unit, and maybe someone else on KRNet also knows about it, so I am going to include this email to KRnet, so if anyone knows more about it, they can get in touch with you.

The reason for this email is that the existing speed brake arrangement on this KR2 is ridiculously unreliable (it uses an old window wiper motor and wire arrangement an no mater what I have done to prevent the wire form coming off or jamming never works. So far its always only ever broken after he has landed but would hate to find he needs to retract it for a go around and find it jammed fully down) and after doing a Google search and also looking on the KRnet site found your system. My question is what was the final size of linear actuator that you found suitable ? I am assuming that something around the 6" would do the trick? would prefer a good sturdy unit from the states etc but all I can find at moment is ones made in China. I suppose the items coming from China are getting better but.... Dan any help would be greatly appreciated.
