Default Solder ESC directly to motor or use bullet connectors?

1. Should I solder the ESC wires directly to my motor or use bullet connectors like the ProTek R/C 3.5mm "Super Bullet" Gold Connectors ? And why?

2. Is it a difference between 3 points of failure (3 soldered wires on motor) or 9 points of failure (3 on motor plus 6 bullet connectors)?

3. How much resistance will these bullet connectors really have in the grand scheme of things?

4. If soldered directly to motor, what do you do when you want to rebuild or replace the motor? Just cut the wires or try to unsolder them?

For reference I'm using a new Justock and a new Hobbywing Xerun 21.5T for Outlaw VTA.

Thanks,
Brad

I use connectors just because I change motors so often. Their is less resistance soldering them directly to the motor, but I can't tell the difference. IMHO. I'm sure a lot of people disagree.

If you plan to change motors frequently go with bullet connectors if you plan to stay with just one go with direct solder it makes a cleaner install and has less resistance though with quality bullets it's a negligible difference

Use the qteq power terminals if you want to make a solid connection and be able to swap motors. Reflexracing dynamics has them in stock.

Desoldering and soldering takes maybe 30 seconds total with a good iron. I'd just go that way. Cleaner install, less resistance, fewer parts.

the only bullet connectors on my RC's are for the battery.

UNLESS >>>> it's a unsensored motor.

I AGREE - I like using plugs mainly because my stuff goes into one car, into another car, etc... I've run both - and I'm not a .001% guy so I don't notice the difference (I didn't notice the difference in Paved Oval either )

and I have to say - it sure is nice changing a motor w/o HAVING to solder every dang time.

Just had a good look at those - I like them a lot. Very neat solution. You would notice nothing in terms of drop with solid connections like that.

Very tempted!

Solder one bit to wire. Solder other bit to motor/ESC.

Do up bolt.

Simples!
