HK2221-8 V2 Scorpion Brushless 450 Motor, what size bullet connectors does it come with?


Does the 55A ESC come with connectors, if so what size?


(Can they handle 55A for the -6 motor??!)

Thanks!

The Scorpion HK, 22mm, and 30mm series of motors come with male and female 3.5mm bullet connectors. They can handle much more than 55A. The ESC does not come with bullet connectors or a power plug. They don't try to guess which plug you prefer, but most people use Deans.

Oh the motors come with both connectors! Nice so you just have to solder on the female ones onto the ESC?

So why is 4mm more common I though the bigger you went the more amps it could withstand? Well if 3.5mm can handle 55A that will do me just fine!


Thanks very much!

it's good to see that my favourite 3.5mm MPJet gold bullets being confirmed as among the best, my own testing showed this but it's nice to have it confirmed by others

I looked for the post you are referring to but couldn't find it. What was said? In what way are they better?

Thanks.

Connector tests, in German but the numbers are international:

-> datenbank
-> Hochstromsteckersysteme

Gerd Giese also does a lot of testing for the Drive Calculator motordatabase.

Prettig weekend Ron

Hey Jimmy,

How ya been.

I wasn't aware that you could run any brushless ESC/motors in tandem??

But most have forgotten more than I'll ever know!!

Jim,
Please review the charts posted at the beginning of this thread http://www.rcgroups.com/forums/showp...3&postcount=68. For example the 2215/22 motor rated at 200 watts is starting to overheat at anything over 100 watts. True, static testing creates heating challenges, but very surprising considering all the advertised high temperature components in the motor.

One item with these tests that relates to heating would be the constant power source used. The voltage would not be dropping with increased throttle as it would be with a lipo pack. I notice that the prop is being used as a pusher as well, so again not as much air flow through the motor as would be in flight. Finually, with the higher temp rated components of the Scorpion motor, I would think it follows that it can handle the higher temps before letting out the magic smoke.
