Default 2x 1/4 Servo's and 1 MM?

I've read that the CC BEC doesn't like 1/4 Servo's. Well whats the other options to run two 1/4 servo's off one Mamba Max?

I have a CC BEC running a 1/4 scale and a 5955 with good results........ I do not think a MM would like it all.

Ya the MM alone wouldn't like even one of them...lol I'm stripping my Super down to lower cost parts and putting them on 2.2 rigs. I now Badd was having bad luck with CC BEC on 1/2 servo's. I might leave one 5955 and try a 1/4 in the rear with the CC BEC. What do you have your BEC set on? 6v, 7.2v?

Can't you run 5955TG with a TQ3? I know a few guys on here know how... So How?

By either adding endpoints to the tq3 (it's in the tq3 sticky I think) or make very certain that you have your steering links set up so that you get max throw with no binding at the end.

Personally, I wouldn't use a digital servo with out having endpoints.

I'm running a MM, a CCBEC set at 7.2 volts, a 12volt E-Moli pack, and two of your TP 1/4 scale servos with a dx3r. Not a single problem.

Well I'll give that a try, but with a TQ3. The 1/4's are not has picky has the 5955TG's.

It can trip with two 1/4 scales or two high power 1/10th scale like the 5955's. Whether or not it does is up to you and the terrain. Rip rap is too much. Capen park is no problem.

Would two CC BECs be an option? With a y harness to the reciever?

x2... JHH there's got to be a way around this. Would the MPI Reg work better?

The MPI reg would work on a lower input voltage like 8 cell nimh. Two BECs would best be isolated from each other- each dedicated to a servo.

How would you isolate the two. It's been a few months since I installed mine. Don't they just plug in the Batt on the RX on one end. Then other end ties into your Power source?

How would you give each CC BEC it's own servo?

This may sound stupid. So bare with me. What if you run two TQ3 RX's on the same Channel.

-One with the ESC, Servo #1 and CC BEC #1.
-The the other RX with just a Servo #2 and CC BEC #2.

Could that work? Or something close to that?

Basically just put the servo on a y harness with the BEC, and snip the red and black wires right before the RX. Only signal goes from RX to servo, then you have the two female plugs on the Y harness plugged into servo and BEC.

So on the " V " end of the Y harness. Plug one Servo/BEC into it. Then the " l " end plugs into the RX. But cut the Red/Blk wires on the " l " before plugging it into the RX.

I'm lost once you say two female plugs on the Y Harness.
