B13DLM V2 4.5KG 0.1Sec Micro RC Servo

Great servo. 2nd I’ve installed and no issues.

I read several reports that the original front wheel servo motor & plastic gears do not hold up to landings, so I got this one with metal gears. Its fits pretty close, but I did need to put a small washer under it where it screws down to the main board, or else the arm on one side would interfere with the servo controlling the back flaps (ie: I had to raise this guy's arm a little to go over the other other servo arm on the side).Other than that, seems great.Pay attention to (take pictures of) the old one before you pull it out to make sure you get the new one situated right. (things like how far out on the arm does the control rod connect? Close to the center shaft or out on the end of the arm for more motion, etc). Also note which slot it plugs into, and which wire (light or dark) is in front when plugged in.My plane is the AeroScout S 2 1.1m RTF with SAFE - Good beginner plane, and it is one of the choices to practice with in the STEAM "Realflight Training" simulator, $39.99. Then I got a USB plug that goes into my PC, allowing me to use my actual remote control to control the flight simulator, so my fingers get all the muscle-memory of what buttons to be using, exactly the same in simulation and real flight. Very nice.SAFE mode is awesome - "save me from myself" features 3 settings:1) Beginner: I have no idea what I'm doing, dont let me crash - automatically keeps plane level and prevents most drastic moves on your part. You basically get to fly in a circle using tail to turn.2) Intermediate: Ok, I'm getting the hang of this, give me some more freedom to maneuver, let me bank the plane, but no enough for barrel rolls or loop-de-loops, but more freedom.3) Expert: Ok, I got this, give me full control. Barrel rolls, head over heels loops, etc.AND most importantly: OOPS, I've lost control, press the PANIC BUTTON for instant beginner mode, auto level out, etc. Very cool, I highly recommend paying the extra $100 for the SAFE feature.

I was hopeful when I saw all the great reviews. However, here’s a couple things I wish I would’ve know before purchasing for my traxxas trx4m. What should’ve been a 15 min swap turned into 2 hours.1. The servo gear head is smaller than the OEM traxxas, so you have to use one of the provided servo horns, which will take some drilling to make work. (Or buy an adapter to pop on, problem solved)Also, the OEM servo horn is threaded, whereas with the provided one I’m going to need to figure out a long term solution so my screw doesn’t work its way out, like a tiny nut. (see pictures)2. The base of the servo is slightly longer than the OEM, so you have to shave the two little tabs off of the servo cradle to get the new servo to seat all the way. Not a huge deal.We’ll see how it holds up to my 4yr old boy, seems to be strong and snappy and of high quality, BUT, definitely not plug and play.

I wanted a reliable and strong servo for the dig conversion on my SCX10 III Base Camp and this servo has been great. I have been running this servo for a few months, and it has performed perfectly.

Stock servo died...lasted longer than I expected but still but the dust. After checking online I came to the conclusion this is the best option. Ordered it. Trimmed the little tabs on the stock servo mounting bracket(there's a great video on YouTube showing this) and installed. More power than the stock servo and much faster.

i wanted to give this 5 stars. i really did ...but then. during my 1/16 scale crawlers maiden voyage around the living room floor, over no obstacles just a flat floor it worked amazingly awesome for the first 4 minutes then seized while in a turn. when i got closer i noticed a faint scent coming from the servo. the servo burnt up. which is a shame because it was working so well. the proportional steering and the speed of the steering was great. a $20 mini servo should last longer:/ perhaps just a dud.so i gave it another try and bought a 2nd one. this one making it past the 4 minute mark i thought maybe the last was just a dud. well, not quit. the 2nd servo did indeed make it past 4 minutes. making around 10 minutes of run time. sadly this 2nd one burnt out as well, just like the first one did. light driving on the living room floor. i really want to believe in this servo and get it in the dirt. looking into causes with the truck, everything else seems to be fine. if i reorder this or with any other servo i get in the future i'll try turning down my steering rates. short of getting 2 duds, thats the only "fix" i can see for now.while working, worked great. though it is a bit loud.

This servo with a 25T 4.94mm spline is not compatible with basically any other metal servo horn on the market right now. The AGFRC branded one that DOES work is incompatible with the Losi Mini B. Too long, and even if you cut it down, the holes for the ball cup are the wrong distance from the center. Wasted a lot of time trying to make this thing work.The servo itself is definitely strong and seems like it would be durable, but without servo horn compatibility, it's as useless as my locked up EcoPower 827. Why they must make the splines different from everything else out there is beyond me...

This servo is a beast. 100% great action for a shift servo. Has plenty of torque. Not an aircraft guy but I bet this is for the money the best you could get. Now in order to use this as a shift servo you have to modify the bracket as it's about 5mm deeper on the Summit/Revo this is doable leaving a small gap at the top and enough material on the bottom for it to remain rigid. I haven't looked at what it would take to install it on a Trx4 but if you're good with modifications I bet you could make it work. The other consideration is the servo horn spine is smaller than the 2056 so you'll have to use the included servo horns. Which are not spring loaded so you may want to buy a servo saver if you use it for the diff locks or the shift on a Trx4.
