General OS Max 105HZ-R DRS (Demand Regulator System)

Anyone have any experience with the OS 105HZ-R with the Demand Regulator System (DRS)?
I’m trying to decide which one to get. Save $50 bucks and get the non regulated 105HZ-R or is the Regulator something I should most definitely get? Anyone have some insight they can share to help me decide?
Thanks

I'm not a nitro flyer these days but from what i know, the regulator is a pump that is operated off engine crankcase pressure. It's there to give a constant flow of fuel during hard 3D flying when the heli is in unusual orientations and pulling high 'g' maneuvers. If you need it depends on if you will be doing that type of flying.

I`m using the OS 105HZ-R DRS in my Gaui NX7, and it is a pure beast. I`ve been using it for a couple of years now, and I`ll never go back to a non regulated engine now.

I Have 2 Helis with the OS 105HZs in them one with the fuel pump and one without and they both perform exactly the same. Of course that is if the fuel system is setup correct and they are tuned correctly..
