Hi gang,
As the title states, I recently purchased a new Hobbywing Max10 SCT esc and separately purchased a Hobbywing Ezrun 3652 G2 3300kv brushless motor. Welp, I guess I learned a lesson, I wasn't expecting the bullet sizes to be different, the female bullet connectors on the ESC are bigger than the male bullet connectors on the motor? Is this a thing?
What suggestions do you guys have?
1) purchase a set of correct bullet sizes
2) check to see if my local hardware store has any suitable electric connectors
3) hard wire them together

Also it would be nice to have you opinion about this setup? Could it have been better? Obviously with the correct bullet sizes. LOL

I would contact HobbyWing and ask for a replacement of the right size
Thanks for the reply Spanky, I actually thought about that, but technically which one has the right size, or do both have the right size for what they are. I went back and poured over the web pages for these, and it doesn't state anywhere, that I can find, where it states what size of bullet connectors each one has. that's why I entertained the thought of soldering them hard lined together or coming up with the correct bullet sizes for which ever one I want to use.
I will grab a pair of calipers and measure them to see what size each of the components are.

I guess I assumed that the bullet size was a standard thing per gauge of wire, both have the same wire qauge, that is what threw me, when the motor bullets are all loosey goosey in the ESC bullets.

Thanks for the replies @Spanky, I appreciate it.
I measured the bullets last night with my calipers, and the female bullets on the ESC are in fact 4mm, actually 4.04mm. The male bullets on this motor is 3.63 mm. Maybe that is the "standard" bullet size for this particular motor idk.
The leads on the ESC are quite long, I may just hard wire the motor to the ESC? Not ideal but I can make it work?

WithinU, don't hard wire them. Do as Spanky said, go to your local hobby shop and pick up the correct bullet connectors. You can also find them online as well, eBay, Amazon, ect. If you don't have one, you will need to get a good soldering iron and solder, and maybe a helping hands. 61up82BVLmL._AC_SL1300_.jpg

Always hard-wire your esc to your motor for best performance/least resistance.
