some other parts

SkaldidDog · 03-13-2013, 09:03 AM

For anorexic motors I presume. Nice.

by far my favorite XR10 build ive seen to date. i love the ingenuity youve in-bedded into this project. cant wait to see the day when you can finally call it done. if that ever does happen!!

EGRESSor · 03-14-2013, 10:16 AM

next step

need to drill and tap lots holes

EverettY · 03-14-2013, 10:18 AM

Why do the pics say 2009?

EddieO · 03-14-2013, 10:21 AM

Gonna guess his camera's clock is not set to the current date.

Later EddieO

another pic

i need to add the brush hoods and screws , but it should be nearly the final weight
it´s with a 3 segment arm , medium wire , 30t

i my use a 5 or 7 seg. one if it fits

kineteks · 03-14-2013, 03:56 PM

...5-segment cobalt magnets?

TSK · 03-14-2013, 04:14 PM

And people thought they ran custom motors....

All these killer parts and you cant clean your shocks

the new ones will be clean

Those motors are SICK! you my friend have some talent, keep us updated!

Yeah, thats what I'm talking about!! I'll be interested to see how your KV compares with a standard 540 since you got your airgap pretty tight, but have thin back iron and thin magnets. Look back on our previous emails about the magnet layout, I hope you made a few extra cans because the armature is very sensitive to magnet position for smooth startup.

I have lots of 7 slot blanks here if you need one, it may need grinding and a new comm to fit inside your hood though.

i started with .3mm airgap , fixed the mags with CA glue and tried to spin the arm
fail

the mags were easy to remove , so i tried it with more airgap
and ended at .9mm
it still feels to strong with a straight slot arm , but not to strong with a 3 slot skewed
a 5 or 7 slot skewed should be perfect

i will use the checkpoint brushes and hoods , so it´s easy to set it up for comms from 7.5 to 11mm with washers or shortened brush Hoods

at last it should be exactly the motor i wanted
power/torque like a 30t , small diameter and light weight

JohnRobHolmes · 03-15-2013, 03:15 PM

.9mm airgap is certainly workable, you will just have a very high KV and low drag. If you want to use .3mm I have some arms we had tooled up specifically for good startup and drag with as tight as .015mm airgaps

EGRESSor · 03-16-2013, 03:19 AM

are your 7 slot arms skewed ?

some progress

JohnRobHolmes · 03-16-2013, 07:23 AM

The current batch of arms are not skewed, but there are some machining tricks and magnet layout tricks to get startup smooth without the skew on 7 slot.

EeePee · 03-16-2013, 08:43 AM

Wonderful, Christian. You're the one that's skewed, in a good way.

hopefully in the right way

front plate drilled an taped

Man, you are a real customizer! This is work of art.. are they ready for the supercrawl? Really like to see some of thes..
