    • Easy kit for for beginners that feel adventurous!
Pretty amazing upgrade for an older brushed Senton beginners truck. Was very easy to install and speeds are insane with the 3s battery. Works very well with 2s 5000 if you want better lower speed control

    • Insane
If you are looking for an insane upgrade this is it right here. I got this for my arrma senton, and it was basically plug n play. Install took about an hour and fit very nicely. I paired mine with ovonic 3s lipo battery and the run time is impressive. I would recomend getting the electroncs cover, because small rocks can get into the cooling fans very easy.very good quality parts and durable . ... show more

    • Works great!!
I had a stock Granite 4 x 4. This kit just screwed on very simple and now the truck is a monster. Almost too fast for its own good. Lol. The instructions were not exactly step-by-step, but they were close enough to figure out.

    • I like it so far
Easy to install! Worth the value for all the parts you get with it. Seems to work well

Review Image by jonny80s
Bought this because I knew my kid would be disappointed with what the wife was willing to spend on a basher at Xmas. He burnt out the original motor pretty quick. So after a short 3 months I finally got to install it on the Granite 1/10. Easy install. The only issue I see is that the old gear box (twice as thick) is clipped and screwed into place. This new one simply clicks into place. As this thing gets bounced around I’ll be curious as to how long it will stay in place. If you buy a new battery tie down kit it looks as though there is a wider block that will help keep this gear box positioned, we’ll see. Other than that looks like it will be overkill and I fully expect to be replacing a lot more parts in the near future….. ... show more

    • Powerful!
Almost too much power for an ARRMA Granite. Really fast. Unfortunately, my receiver quit, so can't speak to longevity.

    • Received open box, missing components.
Great motor and esc upgrade. Unfortunately, this one I received was an open box missing hardware and the additional spur gears.
Reviewed in the United States on March 3, 2025 by Tires do not come glued, and they are to loose on the rim to glue them down. Do not recommend.
    • Fits on Senton 4x2 (4x4 Convert)
Fast shipping, easy install on Arrma Senton 4x2, easy pairing with remote and extremely fast. Overall no issue.
