I've used the Trim wheels from Ed @ GNM on 2 jets now, and I'll likely use them again. My Stingray originally had a cheaper alternative on it, but the saying "buy cheap, buy twice" comes to mind... The Trim wheels/brakes and the Trim valve work excellent from my experiences, after greasing the hub with Parker O-ring lube.

I also use 2 independent air system for the same reasons a Jeremy mentioned, although I only have one inlet for both systems on my Hotspot. Its a single inlet valve, followed by a T, then a check valve to each system. I run both systems at 120psi and see no reason to change since the brakes are activated with my trainer switch. Modulation isn't exactly a concern, and it seem to work well... I tried down elevator mix when the gear's down, but eventually it bit me.
