Hobbywing quicrun fusion SE question.

[rcdadelectrician]

Hello guys, I just came accros this hobbywing set up and I'm really interested in it. I know the cons of all in one units but I really can't spend the big bucks on a more expensive brushless set up. My questions is.

1200KV vs 1800KV and why?

This will be going on my trx4 with locked diffs and the 2speed gear. I'll be installing 2.2 wheels and tires soon (not sure if this will affect it)

I am not a comp crawler as I am relatively new to the hobby (started last spring) and if I ever get more serious about it I would just build one.

Thanks in advance.

the lower kv motor would turn the larger tires with a little mre ease, but neither would have any issues in
the low kv is gonna like the torqe a little better than the higher kv

1800 for a little more speed. I initially bought a 1200 for my TRX4 and sent it back for an 1800. I primarily rock crawl and, even for that, the 1200 was too slow for me. No noticeable difference on the low end between the 1800 and the 1200 on 3S. They are both super torquey and smooth in my truck.

Thanks guys!

I put the 1800 in a mostly stock Basecamp and thoroughly enjoy it. It moves plenty quick for the terrain where it gets used most which is trailing between crawling obstacles.
The best part? It’s quiet.

I've got the 1800 in my Ecto.

The crawler canyon guy I watch on YouTube preferred the 1200 because he didn’t need extra wheel speed, but for his element stuff he said he couldn’t gear down the 1800 enough to match how smooth the 1200 is at very low speed.
To each their own, but I would probably go with 1800. I like wheel speed sometimes

You can easily gear down a TRX4 for the 1800. I have one, in a 2 speed with locked diffs and underdrive in the rear. Works really, really good. I don't think the 1200 would have enough pop. I strictly rock crawl but you can set it up for trail running or whatever. Great piece of kit for the price. Also, a 2in1 makes for a much cleaner setup, without the motor wiring to fight with.

I just watched his video this morning, really cool Chanel! I'm leaning towards the 1800 due to the bigger tire size I'm installing and I do more than rock crawling!

Makes sense! And the look I'm going for i need the whole rear of the truck to be clear of wires!
I'm going to try the 1800 and see if it works as is for now and adjust as needed.

The guy rambles on and on! He is honest though, and he has very specific lines where he puts different tires, chassis, and you name it to the test. His methods(madness) are solid. Before I buy tires or even a crawler, I find his videos so I have some feedback.
