Great job. Thanks for sharing this valuable information. Your setup came out sweet! 👍🏁

Can’t wait to get mine and do the same. Great vid bro

Solid video man!! Thanks for the video

Holy smokes that thing is fast. Whew !

A lot of engineering to fit all those electronics in such a confined space. A nice and tidy job.

Awesome bro ! 👏👍. Happy Easter . 🐣🐰 . I m working with a hbx 16890SA with 3s batteries and she smokes with that 3700 2840 . I don’t understand the throttle thing when I start it . If the red light is on the car by the throttle thing the center knob has to be adjusted until it goes out . I thought that was my throttle control to adjust the power . It’s around middle but the car won’t work all the way up and goes forward .

Wow. Never wanted a smaller scale rc until I just watched this video. Which do you like more between the granite grom or typhon grom. And do you have any issues with the diffs? Thanks!

Diffs are a must! But once that is done things are pretty solid. With abuse or bigger tires I would recommend axles as well. Need to test the Typhon some more to make my mind which I like better

Hi RCKIller! This is a FANTASTIC video… well done and thank you so much! A couple of questions: 1) Where did you get the little legs for the direct servo mounting? 2) Where did your package of motor mounts for different pinions come from? 3) Where did you get the motor screws from?

@Killer_of_RCs

Thanks! 1) The ESC mounting 'feet' are from the Hot Racing kit hot-racing.com/?partnumber=GRM2401;c=1909 2a) It is the Arrma mount set www.arrma-rc.com/en/product/motor-mount-set-8pcs/ARA320744.html 2b) Pinions are various tooth counts from LC Racing, I bought several from www.hobby-addicts.com/products/lc-racing-l6032-motor-pinion-gear-set-17t-18t-19t-for-3-175mm-shaft?_pos=1&_sid=d8fc1550b&_ss=r 3) Motor screws I have a large spares box I keep. I think the new motor needs M3 screws, if you don't have any handy you can get a starter kit of spare screws from Amazon (or Jenny's for the larger scale RC's)

Thanks! It's not mounted with velcro, it has double sided tape on the bottom. However it isn't a good surface for it to bite onto, so it can move slightly. I am going to maybe use some on the sides as well to firmly locate it onto the chassis so it cannot jiggle at all. Moving around a little won't effect normal operation, only will effect the gyro as it will try to correct for any tiny movements.

holy shit! 52mph on 2s!!!!! the mojave 4s does that speed on 4s!

Did you use stock pinion and motor mount for brushless motor?

@Killer_of_RCs

3 ай бұрын

If you kept it 18T, you can use the stock mount. I didn't, so I use a different mount. There is one 2838 size motor with a 2.3mm shaft, that would allow you to reuse the stock pinion gear. All others are 3.175mm shaft so you'll need a new gear as I talked about in the vid.

I would rather use a smaller 2440/2445 motor with a 2.3mm shaft. Just to be safe. Also KV is not "kila volts", it has nothing to do with volts. KV is rpm per 1 volt, meaning 4800KV is 35520rpm with 7.4V 2S lipo. And 53280rpm with 11.1V 3S lipo if motor and/or esc can handle it.

@Killer_of_RCs

3 ай бұрын

A lot of them are 2mm shaft, but there are some 2.3 and there is one 2838 that has a 2.3mm shaft. If anything I would go with that 2838 over anything 24 mm. You have smaller bearings, smaller rotor, and smaller surface area to try and dissipate all of the extra heat. And you can't use the factory heatsink on it. If anything the larger shaft would be safer - you don't have to gear it crazy like me 🤣

For sure, I don't even know why they make aluminum pinions. This one was light colored but it is steel, I've had quite a few different combos on the different Groms without an issue. Diffs are a weak point, the Typhon got the upgraded diffs before I even ran a pack through it. It's a must have.

@@Killer_of_RCs Ha! Back in the day, we used plastic pinions for a 1/18 scale. For brushed 370 motors. For indoor carpet brushed racing they lasted just as long as any alu pinions. Brushed 370 are in 3600-3800KV range and they were ok for indoor tracks. Also, 3S 11.1V lipo cooked them to a crisp in 10-15min. Also back in the day, we used to have all plastic diffs as well. Well for 1/18 and 1/16 scale and maybe some professional 1/10 (cos plastic vibrates less). Today with a 6000KV brushless "Steel All Around" is a must. That 60mph sure comes with a price tag. Though 1/10 professionals ran brushed 540/550 cans as long as they possibly could, even with brushless being cheaply available. Funny interesting how things changed in 10 years.

Very nice. I have a few Tekin mini rage esc, they go 4s! I wonder if this thing could hold up with my 6800kv on 4s! HAHA I have not been impressed with minis for a long while, this thing looks good.

A short chance! It is marginally faster than the Granite Grom that I am very familiar with. Indoors, very small spaces, or kids, it would be great. But personally, anything less than 30mph is too slow for me. I've overshot that by quite a bit but can easily be dialed back with timing, throttle limit, or a gear change.

This is the new XERun 4600kv sensored motor. With the adjusted timing it behaves more like a ~5600kv motor up top. A normal unsensored 4600kv motor with the same pinion would probably be around ~43mph on 2S
