They're quite nice, I have two in my MTX6.
The only two negatives I have found rn are the power draw and noise. If you're running them in an electric make sure your ESCs BEC is powerful (at least 3 or 4A). And yea, they're a noisy bunch.

As far as I can tell theres zero. At least based on how theres zero play in the servo horn.

I want to put them in my losi x, you think they have enough power for offroad 1/8 scale?
and my reciever pack is 2s life, that means they will be powered by 7.4v, correct?

No, LiFE nominal voltage is 6,6V

Throttle will be 100% fine, steering should be okay too, I don't know how durable the gears are (not a ton of jumps in onroad, haha) so I'd set the servo saver on the looser site, just to be safe.

Ook, good to know that, so how can one run hv servos in nitro buggy? I mean at higher voltage?

yeah I'm pretty sure throttle will be fine, there's one mean triple at my track so we'll se how that one goes

i have about the same slop thats developed in my nitro pro 460 with about 20 race days on it in my 10th scale buggy
been super happy with it either way. ive got another that ill swap in for next indoor season

To run "HV" you'd need to use a LiPO battery, which gives a nominal voltage of 7,4V (fully charged it's 8,4V). Don't worry if you have a LiFE already, just use it - most of todays servos have specs so high that the increase in performance is minimal. When I started switching to LiPOs I used older LiFE packs on practice days and at times I wasn't even sure which one was connected. And when you buy your next battery, you can get a LiPO knowing your servos can reliably handle the increased voltage.

I just checked one of mine like this and yeah there's zero play after 53 packs. Neither does my Reefs with 114 packs.

Note that NitroPro offers a lifetime warranty on their gears, no idea how the RMA works but I would consider contacting them to see about getting a replacement gear set before buying a new servo.


I just happen to have 3 gear sets from all my AGFrc branded servos that failed.

i think you have to send the servo in to get it replaced and they fix or replace for $15 no questions asked.
I already have the second because a send in replacement warranty doesnt do my any good when a servo fails on raceday haha
ill swap in the new one this fall and send the old one back for some new gears.

ive got the nitro pro 650 in my mbx7r eco and thats tight as can be

Yea the Nitro Pro “warranty” is very misleading and who wants to go through the trouble of sending a servo in for a simple gear replacement

They are doing R&D from failures and using info gained for changes to design as can be seen on running changes to servo.

Heck, yes there is a big 6.6v on my pack.
I thought it'd be same as lipo.
Well tnx, putting first car together, mistakes can happen

That's really disappointing to learn that I have to ship the servo back for stripped gears and will have to fork over an additional $15 every 15-20 race days like that. It would be better off to buy a handful of gear sets in bulk from AGFrc for $13/ea + $20 flat shipping.

After doing the math in my head, I've come to realize that it's not worth it to continue testing the upgraded pin that I installed 5+ race days ago. I'm going to blow through too many gear sets that it just won't be worth maintaining NitroPro nor AGFrc servos... c'est la vie!

So far I've got 6 race days logged with the SRT 9032 in my eBuggy and couldn't be happier with it... many years ago I got 2+ years of use with that same servo in my EB48.4 and ET48.3 without a single stripped gear nor any slop.
