  • One of the best things about this hobby is tinkering and modifying your RCs, adding personal touches and testing different set-up.
    DEFINITELY no exception going from brushed to brushless.
    Today we up the punch on my Arrma Grom with the first of many set-ups, gotta go a RC Crazy set-up at some point don't we?🤪

    The HSP 2440 4500kv motor is no longer available but any 2440 upto 2845 and between 3000-5000kv will work.
    Remember to get the correct ESC depending on the size and kv's of the motor you choose.

      The wing is just 1mm polycarbonate or plexiglass sheets from the local hardware store.
      You can also use lexan like the RC car body's but it's no where near as strong as polycarbonate

    Definitely the best video to show what a brushless Grom can do on 3s. You’re jumping it 60ft out! I’ve been waiting to see what it can really do. Keep it up. I’d love to know the right kv to get good performance and temps. Also, maybe bigger tires? Can it double/triple backflip, still stay balanced on the ground, AND not get too hot?

    • @rccrazy
      @rccrazy  6 месяцев назад +1

      Thanks mate I really appreciate you saying that🙏
      It is a little weapon and still so much potential left in the bag!
      I personally wanted to go 3300kv but a bigger can size, probably 2845 but I can not find mod0.5 pinions for 3.175mm shaft easy and that size motor has 3.175 shaft😭
      I did find a much higher kv 2840 motor with 2.3mm shaft(revealing that soon)
      But hopefully it will have better performance with the stock gearing but only having to run 2s.
      Currently it doesn't have the wheel weight or speed for triples, possibly doubles with the right ramp but it definitely need more back up speed and as you said larger or even just heavier wheels👌

      You are very welcome Michael😁
      I'll get there eventually, have all the info and all the links for all my vids🥴
      I just used the Maverick Atom alloy shocks I had on the Atom, they are only about 5mm shorter but definitely feel better and MUCH stronger.
      And yep, some channels have been reviewing and advertising the Arrma brand upgrades as if they are easy to get, no one has them🤦
      Hence myself going for GPM parts.
      Hot Racing I think it is have the steel diff cups but I wouldn't use them with the plastic internal gears, definitely need those upgraded diffs!
      And yeah that wing does a fantastic job of keeping the tray part of the body together, dads was already squished after 2 drives🤣

    • @Mick_Au
      @Mick_Au 6 месяцев назад +2

      Thanks will have a look at the shocks and get some…. Have also been eyeing off an Atom 😂
      Going to get some GPM parts also. I think there has been a few strikes going on at the docks so I’m guessing there is a lot of held up ships with shipping containers so I dare say that’s why stock of a lot of things has been terrible.
      Hoping this changes and we start getting some goodies coming back into stock.
      Cheers mate

    • @rccrazy
      @rccrazy  6 месяцев назад +1

      Honestly the Atom once you get some shims in the diff and grease in them aswell it is a tough little car.
      The oil shocks help heaps also, but it still works out less than like $150aud.
      Controller is annoying but easy to swap out for a hobby grade system and little brushed esc👌
      But yes some of the GPM upgrades for the Gram are well worth getting and they look BEAUTIFUL🤩

    Awesome man! Did you pull full throttle when doing backflips or can it do double backflips on those jumps?

    • @rccrazy
      @rccrazy  25 дней назад

      Thanks mate!
      With this motor I kind of needed full throttle for backflips because the car does pull nose down a little when jumping, no weight in the wheels either which makes it harder to get the rotational force.

    • @rccrazy
      @rccrazy  25 дней назад

      This one is 4500kv so 4000kv would be slower on the same gearing, you could go to maybe a 5000kv to 5600kv with the same esc I'm using and it would be more capable.
      Higher kvs faster speed but they will heat up more as the RPM is higher.
      If you go higher than around 5600kv you may need a higher amp esc like a 35a or even 45a.

      @rccrazy  24 дня назад +1

      Yeah totally fair enough, I've not had a mini e-revo so I'm not sure how they would compare to a Grom.
      But the TK16 is actually a very tough little car and very stable, I would probably say more stable than the Granite Grom but not the Typhon Grom.
      Hopefully you would be going brushless because the stock system to put it as nice as possible is junk😅

    • @rccrazy
      @rccrazy  6 месяцев назад +1

      Thank you!
      No not bad for the servo, the gyro can negatively effect the car when jumping, because it's trying to correct the car but the car is not on the ground it seems to get confused and does some very strange and unexpected movements to the car.
      These gyro actually change directions when upside-down aswell so for a few second during a backflip it's actually correcting the car the wrong way😅

    • @rccrazy
      @rccrazy  6 месяцев назад +1

      I would avoid using a lower amp esc than 35a with the stock jjrc motor and gearing as it is too high kv and is a long motor so I think it would potentially damage a 30a escape on 3s.
      The Grom motor is more kv but much smaller physically therefore requires less continuous and peak amps.
