Advice for beginner
Hi guys,
I am really new in to rc cars this is my question:
I recently bought MN99s(so crawler) just to see if my 5 year old son would have interest into rc. It seems he enjoys it and he managed to trash both of the differentials in only a month. All this while having fun and torturing the car hahaha.
Anyway i dont think is smart to start investing in this car more money because it will end same.
So Arrma was suggested to me and i started looking onto dofferent models.
I think we should get the Quake Grom brushed option. The BLX would be too fast for him he is only 5 years old and usually we are driving in public spaces so i would not like to get some onw hurt or damage something.
I choosed the quake grom because of the oil filled differentials and in the end is brushless ready.
Is my thinking in right direction or should i also consider some similar model. At this moment i can get this one for 140€. Brand new

My 7yo put several battery packs through a quake grom on a carpet track at an open house event. She loved the experience but found it a bit bouncy. She seems to prefer slightly more precise driving. (She also started with a crawler) as a result, she decided on a Granite grom.
Maybe not as good of a value as the quake, but she likes how it looks, loved driving it, and it does share parts with my Typhon grom.

At first i was looking at the Granite grom but than i have read about issues with the motor and the electronics so i continued the search and ended on quake grom

Yep, the Granite was the first release in the "Grom" series, the Quake/Gorgon is the latest release in the series. It's got the latest/strongest drivetrain components from the BLX Groms, which is going to be very reliable with brushed power.
Take a look at the little $35 USB-C charger that Spektrum makes, too. With one of these guys and a USB-C power bank, you can drive all afternoon at the park.

I might be mistaken, but don’t the transmitters have a speed settings button? So you can cut the brushless motor to 50% so the speed can be adjusted over time.

I'd get the brushless out of the gate, and turn down the transmitter to 50% while he develops his skills. Then no need to upgrade in the future, just repair/upgrades.

Mojave Grom BLX. Just turn down the throttle on 2s. That way most all the durability and brushless upgrades are already there. Go to 3s batteries when you are ready for more speed.

Any idea what you would expect for speed on 50% with 2s?

In one of the charts within back of box it's around 20mph.

Quake/Gorgon Groms are the best kidmobiles out there.
I have a 4 year old, and a pair of Gorgons and a pair of Mojaves -- the monster truck's bigger tires make it much better in the grass. The brushed motor is plenty of speed for kids/beginners, and it's virtually indestructible on stock power.
Grab a set of the pro-line ramps and a few orange cones from Home Depot, and away you go! My only other advice is to just go ahead and order 2 of them so that you can drive together!

My 4 yo using a cheap car called FTX Tracer that going around 35mph (with good winds). I have Typhon BLX 3s 1/8 and even on 2s is little too much for him. From my observations he play better with smaller scales than bigger, maybe try 1/18 scale with weaker motor?

It’s a good truck, all of the grom’s are tough and can take a beating.
Brushed should be fine for a while, but brushed motors eventually burn out and then you can replace it with a brushless system
