I just think it's strange this wasn't noticed in beta testing.

edit: just read mike's post. So, I'll drop to 5.5 or even 5v bec output and it should be solved.

It's not really a "problem", it's the way it was designed. Dropping the voltage will help and adding a capacitor (~10,000uF @ 10V) can also help supplement the BEC under peak loads.

I'd rather limit the load on the bec, so I might just drop to 5v. The 985mg was the smallest servo I had lying around. I forgot I actually used that servo in a Muggy and it did okay. Kind of puts using this servo in the mini ste into perspective...

/sigh

The MMPro BEC is actually just as capable than the MMM BEC, which no one has complained about.

The BEC on the MMPro wasn't designed to run multiple ultra-high-torque servos. It's a 1/10th scale and 1/8 buggy controller.

The current limit is set to about 4.5A on the MMPro BEC, but will fold back if the temps get high. Remember, this is a pretty small integrated BEC.

After my "glitchy" run, I dissected the non-working servo and found it's control board burnt. Even though, it was the first time I ran it, I may have gotten a bad one. I replaced the bad servo, with another MG995.

After turning the BEC down to 5.0 volts, I just took another run. It did not Glitch a single time. Yes, this is running a Pair of MG995 Servos.

I would also like to add, the power delivery of this ESC is really smooth.

This is a light weight, low slung E maxx using a HC 8 Pole 1600kv Heli outrunner geared 14/52 (31 mph). Temps on everything were only slightly warm. The ESC's fan only came on one time during the 30 minute run.

A pair of 6S 26C 2600mah Kong Power Packs in parallel supplied the juice.

As for me, I believe the problems I experienced were to blame on a bad servo.

because i am new to the large and nice of a ESC, i can use my new MMpro in a 1/8th scale buggy application?

Yep. It was designed to work in 4S 1/8 scale buggy setups.
