Default Voltage regulators!

I have three types of voltage regulators in stock, the MPI 6 volt, the MPI adjustable, and the Ubec switching BEC. These are a must have item for anybody using high voltage or strong servos. I run them on just about every vehicle and have chosen these three for cost effectiveness and power.

so they go inline from your servo to the reciever which means you would need 2 in a super ?
hustler with dual mamba maxes and 5955 servos with hyperions havent decided on a battery set up yet.

I run 1 reg from the batt to the reciever in my super. Powers my 1/4 scales no problem. I've been thinking of using 1 reg to each servo to get that little extra out of 'em though. I know where I'll order from now

Got my UBEC yesterday. Very nice.

Installed it and tested it around the garage. So far I am very impressed. I can't believe how quick the servo is and how much power it has.

Thanks John

Can the MPI units work with Lipo's also? I noticed that you just listed 6-7 Cells. The on the UBEC you just listed 2-3 Lipo's.

Yep, voltage is voltage no matter what the source.

And I've used the fixed 6 volt MPI with my 2 cell Lipos.

Lipos are just batteries, nothing special really.

It would depend on your main pack voltage. A low voltage pack like a 6 cell would work well with the MPI 6 volt version. A higher voltage pack like 8 cells + would need the UBEC or adjustable reg to keep up. The UBEC is much more efficient at high voltage.

They do, but again the main pack voltage must be considered when selecting the voltage reg.

I would suggest you wait until the Castle reg comes out, or get the UBEC. You have to use a switching reg with 3 cell lipo to get any decent power.

The UBEC is now labeled the Cool BEC. Same price, better construction. Castle regs coming soon...

John Rob,

I'm not experiencing any problems currently but this is my set up; low voltage packs 6-7 cells, Hitec 5645, Mamba 25, brushless (TCS both motors). Nice but mild formula.

But I have run Lipos in other racing scales and love the power and weight reduction.

I plan on finishing out the season in my current formula. But over the winter I have some plans to turn up the burner which will include a voltage regulator.

How far can I push the Mamba 25 if I add a JR 9000T or Hitec 5995, Lipos 11.1 v with those additions which voltage regulator would you suggest?

Will I then need to add the Mamba Max?

Will my Mamba 25 be a good back up or just part of my RC Museum?

Thanx Stormin'

The mamba 25 wont put out a whole lot of BEC power. With a 3 cell lipo you will have next to no amperage available. I would suggest the Cool BEC since it is switching. You can then use the mamba 25 with powerful servos to your hearts desire.
