Tut tut brian, 0.7 sec and 0.8 sec, that's an eternity?
I think you'll find it's 2123 = 0.06 and 2363 = 0.08

I've enjoyed 2123's for many years and actually prefer them being 7.2V as it takes the power supply worries away from the speedo and receiver.
Also as an aside I've heard nothing but good things (including this morning in a shop) about the Sanwa ERG servos, that is irronically enough except from Craig (body paint) who I believe has heard from Brian (tyreman) they aren't to his liking
