Details of the Spektrum DSM2 converted stick sets some of the Horizon Guys had?

[RogerM]

Does anybody have any info on what went into the Spektrum DSM2 based stick sets that some of the Horizon team drivers use/used?

I am looking at options at the moment and although the Sanwa set is much more comfortable to hold than the Futaba it's still a little chunky for my shallow grip & arthritic fingers.
The KO Universe feels natural in my hand but I'm starting to experience some minor issues with the Spektrum DSM module in it & the KO 2.4GHz system seems like a bit of a pain to bind on a busy race day so would rather not go that way either.

That leaves converting my KO Universe to DSM2 as the only currently viable option ..... any info gratefully received!!!
