I am building a razor crazy cart and will be installing dual Sensored 6384 170kv motors. I have done a ton of research but still can’t decide on what esc/controller to use.
I will be running it on 12s with a hall effect foot throttle and want it to light up the front tire when I hit the gas, so I need one that will be able to take that kind of abuse…lol
What are would be your preference for the best bang for the buck esc??
I would go for the Unity over the 6.6. It has much better QC and will be easier to setup. Beta testers had a hard time killing the unity. The 6.6 has the voltage issue and some people have had issues with them i.e. half the board not working anymore
The fit because they are not capable of outputting the rated current for more than a few seconds. I have heard alot of complaints about the unity and how much torque is missing. The flipsky ones are not always flawless but cs has been helpful and quick to fix everything. They can output brutal amounts of power for quite a long time.
Well that is certainly a concern since this will be on a cart, that I will be thrashing pretty hard. I definitely need the output to be up to the task!
You definetely need the flipsky 6.6 dual for its 100a abilities. I would recommend adding a small fan as well. Karts can pull alot more current because you are sitting down and can handle acceleration better. Buying cheap means you buy twice.
Vescs are fantastic controllers with a lot of adjustability and the best electrical brakes so far.
However they also have some shortcomings such as input voltage limited to 60V (essentially 13s is the max limit), limited power output, low max erpm limit, high price etc.
I found this one from flier which seems like a pretty good deal, but my motors are sensored and this esc is sensorless so i’m not sure how well it would work?

I didn’t read the whole post. Bang for buck and a go cart? You got the space then for cooling. I built a 4wd board for a buddy with naked/exposed flipsky 6.6 singles that come in the aluminum case.
I got them for half off during their holiday sale.
Here is Metr Pro telemetry and battery stats. We are using high discharge drone lipos, this is single esc data, multiply some values by 4, others by 2.
These ESCs stay pretty cool, and tolerated fairly high continuous demands. Rider plus board wt is 210lbs + 30lbs. He also splashes water on them with no issue despite my concerns (yet )
Only issue with controllers is the voltage reading variability. Only an issue for data nerds.
Here is me riding on two unity’s for comparison:
Accurate top speed, but just a sprint. His runs are sustained and daily since January.
Finally, I burned up Half a dual 6.6 that didn’t have the aluminum sink. I’m still butt hurt about that. Wanna buy a half dual 6.6 for 3wd? Jkjk.
