It is such a pleasure to work on the Arrma 3s/4s lineup. A lot of thought went into the engineering of this product . With special attention taken into consideration for the person doing the service/maintenance

@HardcoreRC 3 года назад

Very true, i think the Arrms 3s range are there best cars, not they need to make a 1/5th scale version 😂

@ChriswithaCrc Год назад

@@HardcoreRC yeah I agree the 3s cars are superb and so easily upgradeable , easy to wrench on , and have a great following because of the price point . I would love to try 1/5th scale but price wise its out of reach and it's a whole different eco system . I wonder when they will release a new 3s line .

17mm Hexes are coming - been waiting for the M2C ones to arrive. Needed to see how the motor and ESC behaved first though, need to do in stages to see how everything works together 👍

@norcalrc 3 года назад

A quick suggestion, after you put the 17 mm hexes on - try the stock talion wheels/tires. Less sidewall = more stability. Larger diameter - higher top speed potential. Plus you all have them in the shop and probably won’t use em for much else.

@HardcoreRC 3 года назад

Thanks - had been thinking about the Talion wheels, not sure how they will work with air getting under the car though, needs to be down nice and low for the higher speeds, but its an option i haven't dismissed

Can I use a 2100 kv motor to get close to 100mph

@HardcoreRC 2 года назад

You will likely struggle to get to 100mph on the 2100kv, unless you change the body to a more streamline one, you will deffo need a Max6 in any event, found the Max8 would cut out

Might be worth testing without the wing incase the down force kicks in too much around 55ish

@HardcoreRC 3 года назад

Thanks, wing hasnt been an issue yet, we been faster than 55 already 😎😎

@Harvey600 3 года назад

Just made me think, someone else had an issue around that speed, up until then it was okish then started to get unstable. As you say the Hoons will be more stable. All the best with it, looking forward to the next step
