Having chatted to some racers at the weekend (Nascot wood SRC Porsche six  hour enduro ) it seems that I'm the only one who likes the idea of linear slide  controls. 
"Too easy to knock out of position" I'm told. 
Maybe they could be recessed?

There were very few SCPs at this event, lots of old Parmas, lots of tru speeds. 
Some things that did come out of these conversations....

A bad thing about rotary knobs is that they have no ratcheting effect. 
Pots are available that give you a really tactile thump as it is adjusted through its range.

I did not know that tru-speed make digital controllers. 
NOT slot.IT Oxigen compatible though. 
Many of us are locked into the SCP because of digital oxigen racing. 
The SCP is the only controller into which the oxigen cartridge can be fitted.
If tru speed or another manufacturer were to create a controller that could take that cartridge, our team would would be all over it!
