SpektrumFirma 85A Brushless Smart ESC / 3300Kv Sensorless Motor Combo, SPMXSEMC01, Black

Bought this to upgrade an old rustler. It was getting time to start replacing batteries and my main is a 4s Outcast v2 so I wanted to battery share. I figured it'd be more beneficial/cost effective if I run them off the same ESCs so they can battery share (this combo is UP TO 3s) and since I have so much into the spektrum ecosystem, I'll merge where I can. You'll need to reverse the motor for 2wd and you'll want to adjust the punch. You can keep all the traxxas parts. Drilling 2 holes on the ESC mount and using a longer screw for the receiver box to mount the button is all I did to mount the ESC to a stock rustler (if your batteries are thick, you can use collars and longer screws to lift the ESC mount for clearance; I also replaced the battery tie down nuts for velcro so i can use 3s hardcase G2s). For the new motor, transmission is stock so I did upgrade the spur/pinion to a metal 86/21 for the extra power the motor produces. The stock is fine if you just want to upgrade cheaply but I'd imagine it would not last long on 3s 100c because stock is plastic, so keep that in mind for spares. This ESC has an IC3 connector so if you have IC5/EC5 batteries you'll need an adapter (if you want to benefit from their smart batteries you need the smart extension). All-in-all, this was a great upgrade and the 3300kv motor is good power for the rustler platform. Without much tweaking, it was hitting between 42-47 mph with more to go. If you're stock, you definitely need to upgrade the rear wheels.Update 25 Feb 2024:Took it out for an extended run and decided to adjust the punch to 6 (from the factory 5) WOW did that make a huge difference. This thing is a rocket with punch 6 using a 3s 5000mAh 100c battery (G2). I had to adjust the wheelie bar to the lowest setting to keep it from flipping or start walking. Upgrading the shocks to something with a quicker return might help keep the front end down but I was able to feather the speed to ramp it up. What an amazing upgrade and took less than 20min to upgrade. Definitely recommendFinal Update:With all that torque, had to replace driveshafts (factory) as it twisted them in two. Took that time to upgrade the turnbuckles, wheelie bar (to the better metal wheels), and added a can fan. This thing is a rocket but to add any more speed it'll need to be weighted for speed runs.

I bought this combo as an upgrade for my son's 2wd Traxxas Slash because the stock motor went out. Also ordered metal 86T spur gear & 19T & 21T pinion set. I used the 86T/21T gear combo first with a 5000mah 3S Gens Ace battery and my God is it fast!!! Cant keep it straight on dirt or gravel at WOT. Only ran it for about 5 minutes each on the first 2 runs, so not sure if heat build up will be an issue. But I'll update after I've ran it on a 2s battery, but so far very happy.(Update) This worked so well in my sons 2wd Slash that I bought one for my Ruslter, and it just as good as the first. Very quick on 2S batteries with a 86 spur/23 Pinion gear and uncontrollably fast on 3S :)Zero heat issues so far on either one and very impressive battery life.

I’ve bought three of these motor/ESC combos to upgrade my Traxxas XL-5 Stampede, Bandit, and Slash to brushless. It was to install on all three vehicles and now they are twice as fast as before. I also bought the spektrum programmer so I could set the punch, breaking level, and motor direction. Be aware that if you are installing this on a Traxxas two wheel drive vehicle, the wheels will turn backwards. This is because the motor is set up to spin clockwise from the factory, whereas Traxxas two wheel drive models spin counterclockwise. To fix this, you can either program the ESC to turn the motor CCW using the spektrum programmer, or you can simply switch any two of the motor wires, for example yellow to orange.

Great torque and speed on 2S battery! You can run the largest drive-sprocket you can install, and it'll still have more torque than you need. BUT.......running 3S batteries will overheat it (if you approach top speed regularly) and it will go into a limp-mode. I was running my Slash 2WD on blacktop with road tires, and once it reached full speed (Like 70mph!!) the ESC would show a red-light and go to about 15% power mode. You can turn it Off and then back ON and it resets, but it'll come right back if you top it out again.

I purchased this combo for my son's Arrma Granite Voltage 2wd Basher. It's a great product, and I love the Spectrum Smart batteries and many of their products I've also purchased. We use a Spectrum 5000mah 2s lipo battery for this setup, and it keeps temps down enough, and I didn't have to change out any gearing. Due to the placement of the wiring coming off the motor, I did have to do some modification to the plastic frame of the Voltage with a Dremmel to get the motor to fit properly. The Voltage is a hard RC basher to upgrade, as the frame is so small, and congested, I'd recommend not going down this rabbit hole, and instead upgrade it to a more power brushed motor. I've easily spent more money trying to upgrade this basher than I should have, and could have easily purchased a better Basher all together. But if, like me, you love to tinker and upgrade, this is a good place to start for brushless. There are many items you'll have to upgrade on this truck also, and the tires absolutely have to be one of them, as the stock tires cannot grip anything, especially with a brushless motor. The rear differential is also a necessary item, as the plastic factory cups break off quickly. Anything you can upgrade to metal that has to do with the gearing, steering or wheels, you'll want to do. As these parts don't last long. In some items though it's best to keep plastic, as they are able to bend and come back into place without breaking.

Bought this for my team associated DC10. A little too much but after setting the punch control it worked well.

Excelente conjunto para hacer un upgrade a tu Arrma Granite y otros modelos, toma algo de conocimiento que puedes encontrarr en youtube para instalar, no se hace en 20 min. como dicen algunos reviews pero vale la pena.

I liked this setup so much, I ordered another one!

I have put this combo in my arrma senton Mega v3, and it is at least twice as responsive and fast as stock. I started using 3S batteries on this, and it absolutely rips, and has done so for a year, through winter in -20C temperatures, hot summer days in the mud and in sand pits. It's never failed me, which is why I own 3 of these spektrum motors, one for each of my RC. It works well in my 1/10 crawler (which I use as a trail truck), works great in my senton, and so it does in my SMT10 monster truck.

Habe einen neuen Artikel bestellt und einen alten/gebrauchten kaputten bekommen. Der Karton war neu foliert aber man konnte erkennen daß er bereits geöffnet war. Frechheit das Rücksendungen nicht besser geprüft werden und als neuer Artikel wieder verkauft werden

The items came in quality packaging and were displayed nicely in the box. Easy to install. Has made a huge difference to the RC car I installed this in replacing a brushed motor.Have used this on NiMh, and 2S and 3S LiPo batteries. All worked well with higher power as expected from larger capacity LiPo.Highly recommend this product as an upgrade if that suits your needs.

Replaced brushed system in a 2s typhon. Works very well, just as fast as my 3s typhon now.

Product is damaged, and is not new. It has been modified, does not have original genuine spectrum connector, has been fitted with aftermarket xt60 connector. Battery smart sensor wire is broken. Product is dirty, lack of QC, someone has clearly already returned this and no one has bothered to check if it was new or used or blown up.
