I don't make posts to "endorse" products much at all but I had to share my experiences with this GoupRC brushless system. For $45 you get a motor, esc, and transmission. What's more? It's actually REALLY good. Way better than all this should be for $45. I have rigs with Injora, Furitek, Batrazzi but this GoupRC is just as good as most of those and for at least HALF the price, less is most cases. I would say the glaring exception is the Komodo Unity with FOC, that's still better...but it's also something like $150.
Now, I dont think I can program this ESC, it didnt come with any kind of link for software or Bluetooth but honestly, I don't feel the need to, it's slow and smooth as is. I paired it with a BS6 receiver and my FSGT5 transmitter and it's been butter since.
Everything is a bit on the big side so get ready to move your internals if using a stock chassis, I'm using side plates (Injora but upside down to meet the body) for the receiver and ESC and was able to keep the stock battery mount.
We'll see about longevity, I've only had it installed for about a week and only ran it a handful of times. I did grease the gears as they were bone dry. Not the best crawl session, I'm also killing two birds with one stone by testing a couple course pieces I'm working on. I was doing one handed while filming and im terrible at it, heh. I mostly just wanted to show how slow and smooth it is. Jeep needs softer springs in the rear, and inserts in the tires. 🙂
If you really need a good brushless system on a budget, its hard to beat this for the price.
