8s Savage Setup (Cant Choose An ESC) - RC-Monster Forums

Takedown · RIP- Tammy (9/14/08) Lamborghini's= True Engineering Marvel's

I made up my mind to buy two 4s lipo packs to make a total of 8s lipo so that it would make me happy with its overall preformance and the outrunner happy because its running on voltage it was intended to use. I will be using a 53/30 stator outrunner in somewhat of a DD setup. I found that a few people on here use the 110HV ESC for planes in their HV setups and it looks like a qualified ESC to me. I also want to know will the MMM be able to handle 8s lipo with the internal bec disabled? If so then I already have my mind made up.

Im looking to stay under $200 if that is all possible?

i don't think anybody can answer the mmm question yet. i believe you can get a jazz controller to do what you want and still have reverse, but wait for others to respond first.

AZJC, Darn I thought castle would miss the over voltage again on yet another awsome ESC... Im going to be doing alot of speed passes and bashing so maybe 8s isnt for me. 6s is the lowest I will go and if thats the case then Im for sure getting the MMM.

hmm this will probably sound dum.. but here is a thought.....

Get 2 controllers that are ok on 4s..( STOP DONT CALL ME STUPID! lol)
and run Y's off the motor so it can take input from both esc..
since both escs are running off the same emf pulse they will stay syncronized. allowing you to run 8s succesfully.

First time I've ever heard that.

Lol, it seems like it will work in theory.. one signal emf.. 2 of the same esc, same switching rate... should work

Possibly. Ask:

but wouldn't this be just as or cost the same as a controller that can handle 8s..

Exactly what I was thinking...

Probably so, but I just want to know if it would work. I will stack 2 of my controllers I have now that are rated much higher already.....hehe

jzemaxx, if you parallel two esc's (possible?) each running 4S, you have a system with a total of 4S. You can't put them in series to run 8S as the voltage would kill the components that make it a 4S controller in the first place. If you try to put 8S into a motor, somewhere along the line components are dealing with 8S voltage.

you'd be better off with a single 6S MMM.

Exactly right.

I run a savage with mech brakes on 8s with a great planes 60amp hv esc and it works fine. Has a bit of a soft start, but is not difficult to drive around. If you plan to use motor brakes and reverse the mmm on 6s will be your best bet.

thats not right, if one esc is putting out 14.8v and the other is putting 14.8, wouldnt the motor see 29.6?

They are not in series.
