Orca has committed to supplying WCICS with the 2200kv spec motors for at least this season and likely next as well. This comes from the Pres of WCICS who has spoken directly with a rep from Orca, not the Cdn distributor. There is a batch of motors being manufactured. The current combo will be discontinued, as there is a new version of the Spark ESC in the pipeline. There is no word as to when they'll arrive, but this is what I've been told.
I'd be disappointed to see the spec motors disappear, but I suppose it's inevitable in the long haul. The upshot would be having access to more revs would allow me to go to better quality, 55d tires, rather than the S Grips I'm burning through in 25-30 minutes.
