Spektrum RC SX107 Micro Metal Gear Servo

I bought an Axial Capra which came with this servo
to operate the dig function. The servo stopped
working after only 3 battery packs.

It is very unfortunate Axial chooses this servo
to put in their product line.

Too weak for the Axial Capra dig transmission. Servo burned up in two very light runs with the end points adjusted perfectly. Servo running on the recommended voltage. Do yourself a favor and get a Reefrc 99 micro servo and horn.

The Spektrum SX107 micro servo uses a 20t spline micro shaft.

***Please note that the Reefs 99 (25t) or Align DS450 & DS450 (21t) micro servos are not direct replacements as the Spekturm servo saver adapter will not work.

Don’t waste your money on this servo. Spectrum does make good servos just not this one. I put it in my SCX10 iii for the dig unit running on 6v and EPA set properly. It stopped working the first day I used it.

Guys, just a little heads up...I was made aware that if I had an HV steering-servo attached to my ESC along with these non-HV servos for my dig/2-speed and pump my ESC to HV (7.4v) to power my steering servo, you'll most likely fry these guys. So don't set your ESC to HV if you have these...get an external BEC and attach that to your HV steering servo and leave the ESC at normal voltage. Dunno if that would help you guys from burning out your servos but these weren't meant for HV. I'm not calling anyone out in particular as I didn't realize this before so this is an FYI...

And I just gave this 3-stars since it fit without issues but in the SCX10.3 JLU, it's an extremely tight fit in the 2-speed install-spot...I ended up having to shave part of the servo and the area where I installed the servo just to get the cable routed to my RX...and why they made these leads so damn short I have no idea...if you use this servo for your dig and/or 2-speed, you'll need to buy some extensions.

Use in Losi 1/18 Mini-T 2.0. Servo works well enough in smaller car. Banged it up a few times. Thought I had to replace servo ended up being a servo saver. Does it job for smaller applications.

Servo came stock in my rtr axial Capra it lasted for 2 1/2 batteries before dying!

Used on axial Ryft two speed. Set up "EPA,end point adjustment to +40R+27L . It works smooth and has tiny bit of play when in either position,so its not trying to work against its self. Probably 30/40 cycles and its still working. I dont like that you have to buy sx107 servo to get 21t horn.

only lasts a few runs before it burns out! Very disappointed !

Amain recommended this servo for Losi mini b pro. On installation the 20T spline does not fit exactly on my 20T spline servo horn. Very terrible fit. Used once servo kept binding up and gears stripped. I run Spektrum for all my electronics and never had a problem. This product is very terrible. Very disappointed

Would give 0 stars if I could. Absolutely the worst servo to hit the market. Last one I got had a horn that was different size than the previous 3. Ended up throwing it in the trash not worth the hassle to send it back. Amain discontinue this item it is an absolute scam to sell it

Useless product. The Losi Mini B aluminum arm doesn't fit onto the servo shaft. Tried a Hot-Racing servo saver and that doesn't fit. Even the included 20T spline plastic adapter shown in the product photo doesn't fit!!

Contacted HH and they sent a replacement that has the exact same issue. Doesn't fit any 20T spline servo arms.

I'm not sure if they have a bad batch or what, but you've been warned!

if you would like a servo that's gonna just lock up on you in normal use then this is a good one to get...THIS SHOULD BE DISCONTINUED!!!

Went through 3 of these on my Losi Mini B. All it takes is one bad wreck and its unusable. Im currently trying the EcoPower 827 as a direct replacement and am liking it so far.

i think this is what comes in the axial yeti jr. its weak. get a savox and be done with it. everything i buy has a spektrum servo in it, they all fail. Now this particular one is still running in the yeti jr but it is so pathetically weak and slow. One more time, get a savox and call it good!

Cycled once then died. Was not even attached to anything. Don't waste your time and go for the Savox.

Been through 4 or 5 of these and not one has lasted a battery pack. Horizon hobby replaced them all under warranty so that’s good I guess. I’ll be upgraded on my own dime next time around.

Probably the worst micro servo ever. Honestly. It's terrible. Don't buy it. Even when it works it's extremely weak and then after a few runs it will die anyways.

Had one melt on me 30 minutes in, another not work out of the box. But have had 2 others work great with no issues, and they are easy to install. Take what you can get from a $15 servo I guess. Buy a spare if you decide to go with these.

Servo arrived not working. This is the worst service I’ve ever used. We have two mini t’s and both servos went out. Not a reflection of a main, their shipping was great.
