Hitec's best servo just got better. Based on the powerhouse HS-5955TG servo the HS-7955TG has the added benefit of our G2 second generation programmable digital circuit. This new circuit has twice the resolution of our original circuit while adding programmable overload protection. The HS-7955TG has been designed for the most demanding hobby applications including the largest aircraft and monster trucks. Featuring a titanic 333oz./in. of torque at 6.0 volts, all this power is harnessed by incorporating the industries first Titanium gears for incredible wear resistance and two strong hardened steel gear pins and axial brass bushing in the servo case.


Hitec's strongest servo period, the "Ultra Torque" HS-7950TH is designed to operate on a two cell LiPo Pack. Featuring our high resolution "G2" second generation programmable digital circuit and our indestructible Titanium gears, The HS-7950TH has the performance and durability you've come to expect from a Hitec servo. Other features in the HS-7050TH include a 7.4v optimized coreless motor, integrated heat sink case, and a top case with two hardened steel gear pins supported by axial brass bushing.

Not to argue what works or not. But for the few people that do care, I was on the phone yesterday for a while with Hitec talking about the HV servos....

According to the information I recieved - the 7955 servos are not made or designed to handle the 7.4v. It has a G2 Digital Circuit which as a overload protector which is off by default. I was told that if you opted to turn this feature on, then the servos will not work with 7.4v. I was told that the servos have a voltage spike protector that allows it to handle TEMPORARY volt spikes of upto 9.6. But ist not meant to handle 9.6 constantly.

I was able to get the search feature to work and came accrosss a post that stir's the pot again. Look at the third post.

The way I look at it is the 7955TG can run on 7.4v. But will shorten the lifespan of the servo.

HUMMMMM - there seems to be a lot of mixed messages on here about this. I will leave it alone - the specs on the website that he say go to does not list the 7955 in ANY high voltage areas......sorry, but he say one thing but the hitech website say different. a friend of mine just got her 7955 sent back and they would not fix it due to the fact that he ran un- regualted.

my bet is that the 7955 can withstand the higher voltage. they were making that claim before their high voltage line came out. now that it is out, they're less likely to make that claim since they'd probably rather you spend your $$ on the more expensive servo. i'm guessing the 7955 wasn't designed for the high voltage but is probably robust enough to withstand it.

they used to have the 7955TG listed for speed and torque using a 7.4V lipo on their website

Well said and I agree

I would love to see the receipt claiming NO warranty on the specific servo's he sent in....i just know they wont back down on warranty due to 7955's being ran on lipo....there's WAYY too many hitec reps ALL over the net claiming they are fine for lipo...DESPITE there being no written proof on any package or on the site...the Rep's are more then informed enough to inform us of what's what...and like Billy T. from here on the tech to MikeMayberry , tohm over on RCU they all claim the 7955's are Lipo ready...here's a quote from tohm over on Rcu

MikeMayberry

That's highly unlikely... what's her/his name, I'll look up the repair?

7955's while not officially rated at 7.4v should have no issues running 2S unregulated. The 5955 is not as durable at that voltage but seems to hold up fine in most cases.

Hitec servos have been very very good to me over the years and I wouldn't hesitate to recommend to anybody. I have personally been running unregulated lipo power for a while while with no issues even with 5998tg and 5985mg (replacement of the 5945mg)

when there was a hitec forum, the rep stated they will warranty straight lipo to their 7955TG.. and only 7955 and other HV models.

something about the motor being robust enough to handle that much voltage

I am going public with the following statement: I do solemnly swear to never use any servo manufactured by any other company than Hi-Tec. I will always recommend their servos to anyone who has money.I will quit the rc hobby before I would even consider running another servo.I will not jump from the drivers stand without my Cape.

I love my 7955's.

I feed them 8.4 volts and named my steering servo "Buzzy" and my throttle servo "Lactose".

But you gotta love em.
