My MMMv2.0 BEC outputs 6.05v. I assume they changed the bec from 5.5 to 6.0v when they designed the v2?

6.05 volt unloaded, voltage may drop under load even if there is a regulation

Patrick, your pm box is full.

Anyway, here's my message.

The replacement V2 which was shipped on Aug 28 and received last Friday, Sep 5th is dead. I started a thread about it under CC forum.

Anyway, I want to know if it's okay with you to do the BrianG mod and run it with my rx pack without voiding the warranty if something worse will happen. I know some forum members were given the go-ahead to do the mod without voiding the warranty since the MMM is not working naymore.

My V2 puts out 6.0v and my V1 put out 5.42v. I definitly think it has been changed from the origianal 5.5V standard.

Yep , i put the volt meter to my v2 MMM and im seeing 6.0v on the MMM's bec...

With my MMM plugged in & my Futaba Digital S9351 servo plugged into my Futaba 2.4Gh 6ch Rx i am seeing 6v-5.95v, an when turning the steering servo to full lock(left or right), im seeing 6v-5.9v...

Now just for 0.2-0.5sec it drops to 5.8-5.75v when turning, but thats when the servo first moves under a Heavy load / my hand pushing down on the frontend an holding it down, but after 0.2-0.5sec it goes right back up too 5.8v-5.9v even while still loaded up / me pushing down on the frontend....

So the lowwest the new v2 MMM's bec drops is 5.75v, Under a Heavy Load.

I might have to get a MMMv2 and test the BEC like some of the other tests I do. Curious about efficiency, noise, etc...

If you can get it to last long enought to test. lol

[BrianG]

OK, let me re-phrase that to " I might have to get a stable MMMv2 and test the BEC like some of the other tests I do. Curious about efficiency, noise, etc..."

I'm a whopping 30 min or so into my 2nd v2.

Mamba Max Monster V2 dead after quiet 10 minutes first run. sounds like dead UBEC...

No broken servos, no broken motor, no broken anything, since I put back my old ESC and everything is working good as it was before MMMv2

Running 6S Lipo

Sent email to cc... waiting....waiting...waiting....

more to come.. :(

I gave CC a call today, and the Nice lady (Morgan) said that she would give tech my info and they would contact me. She said that CC wants to individually address each V2 failure in order to get a better idea what the root problem is.

Yeah, we are all a bunch of lab rats... and we pay for it ;)

Computer software companies do that all the time.. I don't want to name any of them but M$ ouuuuppss... I just did ! :)
