high volt (7.4v) servos?
 

I need a new servo for my Muggy. I'd like to have just a single servo. I already have a hitec 5645mg in my Revo and it's alright a bit slow but no big deal. I have it powered through my Mamba Monster Esc, so I assume it gets 6v?
I would like to try a Hitec HS7954SH in the Muggy, and it has ratings at 6v and 7.4v.
Will this work if powered through the MMM ESC, or will I need a seperate dedicated 2 cell lipo?

iirc the bec in the MMM is set at 5.5V, v3 and newer may have been set to 6v, I'll have to measure mine. The HV servos will work on a MMM but will not see the full potential. Rather than a dedicated 2s lipo you could use a CC BEC, the output is adjustable with the Castle Link and you could run 7.4V+ to the servo. I would expect the servos can handle up to 8.4 since a fully charged 2s lipo is about 8.4V

ok thanks e-revonut sounds good.
At 6v, the servo puts down 333 oz/in and a speed of .15 seconds...not bad.

Hey man just a heads up I just got a 7950th HV servo with TI gears for $109 shipped. Its probably worth the extra bones... Servocity.com Call em and ask to pricematch Troybuiltmodels. They will sell for $109 & Free shipping...

Perhaps...but money is tight atm. I can get the 7954SH for about $88 shipped...
The 7954sh at 6v puts about 21 lbs/in, while the 7950th puts down 25lbs/in.
Only 5 lbs diff, but only a $20 diff as well.
Do both have similar draws?
