Patick and Matt:

You guys are right. My brain fart. Been using one of the old ones on my HotSpot for 2 years.....dah!

I just set one of the new Jetronics units up on a club member's ARF Roo this morning. It stops pulsing with full on just like the old ones.....It is rather cool with about 1/2 the footprint of the old one. The programming steps are improved as well.

I haven't yet played with restrictors on the outflow port, but it appears with the right restriction, one may be able to crank in partial ON, say on downwind, and not loose too much air before touching down, thereby changing the degree of braking... Reproducibility of air pressure is important, since if you calibrate the partial setting with say 120PSI, and then by the time you touch down, it has dropped to 40, the brakes will no longer hold.......at least with BVM brakes....
