KB45-08XL 1600kv Brushless Inrunner

 Dann 4 points

kv stands for rpm per volt sooooo... if u multiply 1600x24v u get 38,400rpm your meter is not acurate or u need to adjust some settings in it to get the right data :)

I use 5 deg. of timing in a 6s marine setup!

I guess I will have to fire her up when I get the plane built! I'll try 5* to start! Thx bud.

 joby 5 points

yes its press fit so put set screws if you drill holes in it or it will come out!

It's a 2 pole inrunner.I use it in a CEN 7.7 brushless conversion in combo with the hobbyking 150A highperformence esc and it's a BEAST.

 ioanna 41 points

you can

 Peerke*nl 15 points

I use it in a CEN 7.7 with that same esc and with 4 cel 4500mah *40C 20pinion and 66spurgear it dous about 40mph so u need 4 cel or up and use the right gears and U'll be flying and do standing wheelys and wheelys at about 20mph to

this motor could take 100 Amps with the right cooling

 Paulo 13 points

no, but EDF 127mm 80Amp

 mojo1 13 points

No but I have tested it on my kyosho inferno GT and it runs fast!

 Peerke*nl 15 points

P=UxI so if u use a 6 cel with a high enough C rating:3500=22,2x157, so if u have 3500watt and use it with a 6 cel lipo u should be abele to use 157A but that is in theorie in a ideal situation

 wyesguy 23 points

This motor has a lot of power,(2-4hp) and could take 100 Amps with the right cooling

Is Water Cooling Jacket For B4563 Motor compatible? What should I use for cooling? Thanks

 wyesguy 23 points

Yes the B4563 Water Cooling Jacket does fit, you will also need some high temperature sealant, something like Pyrosealant should work well or any gasket glue. The Water Cooling Jacket does not come or is not really made for o-rings

 mojo1 13 points

I have it on my Kyoso inferno GT 4,3 kg and it is fast! But gets HOT. Colloing I use a fan and afterwards I spray with cooling spray

 Peerke*nl 15 points

I use it in a 7,5kg car and it flys.3500wattx1.36=4,76hp so YES it will move that car

 Scott 234 points

If you gear it correctly, in theory you should be able to draw 150amps at 22.2 volt. and YES this motor will suit a 5kg car quite nicely!

Lipo battery can use up to 36 volts

2s 4500mah 25c ps. if u liked the information plz dont hesitate to show.

 bigwoodys17 20 points

I have the exact motor do not run over 6s those motors arent very efficient and produce LOTS of heat so be carefull the power reduces tremendously after it gets hot

 mojo1 13 points

Do not know anything about heli! but I have it in a car and it will get hot!

Hi It's a 2 pole inrunner.

 Jacked1 148 points

Yes it is

 Daniel 14 points

Ja, die Welle hat 6mm!

 dateabhijits 1 points

Yes the shaft is 6mm in diameter

 eugenioca 11 points

5.99 milimeters diameter and 16.5 mm large for your information. bye

 eugenioca 11 points

Hello. Yes, 6mm. bye

 eugenioca 11 points

Hello. Yes, the shaft is 6mm really, i have 2 motors of this and are sized correctly. bye

 Pierre 13 points

Yes :)

 eugenioca 11 points

Hello. Use it with 6S lippo better than 7S, too much energy. Around 4500 watts. bye

 eugenioca 11 points

Hello. 4856 watts i read. bye

 eugenioca 11 points

Hello. I used 2 motors too on a race boat and work greats :)), run better than the original motors. bye

 eugenioca 11 points

Hello. Yes, you can use it. bye

 eugenioca 11 points

Hello. You can make like me :)). I use an aluminum tube (6mm outter diameter and 4 inner diameter) rolled around the motor with an inlet and outlet for water using silicon tube and nice :)). bye

 eugenioca 11 points

Hello. I made a cooler with a 6mm aluminium tube for 2 motors on a speed race boat with 2 inlets and 2 oultets and keep it warm, not hot :)) nice, and use another tube folded for the ESC and keep it warm too. Put the tube around the motor and you will have the cooler at your size desired :)) bye

Front plate is threaded ,right thread .Insert two bolts in plate and unscrew. Pull rotor out and bottom plate can be pushed out with some proper size wooden dowel .Pay attention not to damage wire windings .Plates can be drilled for better cooling

 scarletboa 349 points

the bolt pattern is 30mm. you will need m4 bolts for it. the bigger bolts are needed because this motor is massive. i finally got mine and it makes the cc/neu motors look small.

1600kv........look above the picture on this page of the item description.

 norbique 457 points

It would be good to know what your setup is...
Yes you can, but at 33.3V the unloaded RPM will be more than 50K RPMs! It's too much. Go for a lower kv KB motor instead.

 tedy79 19 points

100A ESC will be enough for it! are you using it in boat? as boat ESC usually have water cooling, I use this motor on a monster truck, it works great, heat becomes a problem after 20+ minutes run. BL motor only the maximum AMP at the very start, the quickly drop to 20-30 AMP, so anything with 100A or there about would be fine. You will need a 6MM pinion which is very hard to get, Try kershawdesigns****. or just buy a 5mm pinion and bore it to 6MM.

Brushless motors need brushless ESC's to tell them what to do. To get the most out of brushless motors you should use lipo batteries.
I'd also suggest some research before using the system to be sure you do not damage it. Try an internet search and spend a couple of hours reading up - you will be glad you did.

Thank you!!!!

1. doesnt matter, plug them in, if it goes the wrong way, just unplug 2 of the 3 and replace in the opposite way. eg: green - green, red-red and yellow to yellow makes it go backwards, just use green -green, red - yellow and yellow to red :)

simple. hope you understand.
