Hi Ernie,

 

 

 

How much more torque, percentage wise, would you deduce this -_--_-dv%3AeCom%26cm_mmc1%3DUS%26utm_source%3Dshopping%26utm_medium%3Dcse%26utm_term%3D191040571732&linkin_id=8058742&Issdt=180324062257&searchID=p33.bf4fb88788cd4caf8574&DealName=Reebok+Mens+UFC+FK+BLANK+JERSEY+U+in+Black+Size+2XL+-+Combat+Apparel&dlprc=45.0&AR=1&NG=3&NDP=5&PN=1&ST=7&FPT=DSP&NDS=&NMS=&MRS=&PD=&brnId=14305&IsFtr=0&IsSmart=0&op=&CM=&RR=1&IsLps=0&code=&acode=541&category=&HasLink=&ND=&MN=&GR=&lnkId=&SKU=191040571732' class='bbc_url' title='External link' rel='nofollow external'>FK180 has over a similar wind on a FK130 size motor John - please?

I wouldn't know Ernie, and I sure couldn't just deduce it.  Someone with a dyno would have to make tests across two groups of arms wound the same on the different stack lengths but in motors that are "identical" except in length.

 

 

 

With the stack, being as tall as it is,  how is the balance on this arm?

 

Beats me.  The arm is out for balancing, and I've never done a 180 length arm before.  The lams I used are good though and whatever balance issues there are shouldn't be such that they can't be corrected.  The stack will also need to be OD ground so I hope the stack length doesn't present problems.

Thank you for the reply John!

 

Can't wait to hear your observation of how it runs and sounds, after assembly.

 

I have a a bunch of FK180  lying around somewhere . . . . . hmmmmmmm!  LOL

This arm came back from grind/balance, and to my relief neither seems to have been much of a problem.  The stack is clean and round, and it didn't take much drilling at all to balance the arm.  That doesn't necessarily mean the motor will run great, although it doesn't hurt.  ***It is at least some confirmation that the lams and the stack are concentric, because on a stack this long, issues with that would show up more readily.  Anyhow, I'm going-in for final assembly, and will report back afterwards.

Assembly is complete and boy-howdy does this motor get up there.  :D  It sings a sweet tune and *seems* to have gobs of torque, while only drawing about an amp with no break-in.  As is most often the case, current-draw should go down and RPMs should increase as it gets broken in.  Whatever inline (formula???) this goes in, it will for sure haul the beans.  Nifty motor and (*if I do say so myself) a nifty looking motor too.

Sure is Geary.  This motor will make for a unique car with as much "go" as "show".  :)

Hi Ernie,

     Thanks for looking-in.  I wonder how the longer weight distribution of such a motor will work out.  Even this longer version "fk" is still a pretty light motor, probably lighter than an older C-can motor, but what weight there is will be more evenly distributed between the front and rear of a car...sort of like a "mid-engine" layout in a 1:1 car.

Hi John,

 

I too, believe this motor in an "inline configuration" would work great - due to the fact that it is centered - lengthwise in the chassis, as you just mentioned.

 

I have a bunch of these motors I acquired some years back, and have been planning on testing them on my composite inline chassis - version 4! LOL

 

This motor build is such an inspiration John - thank you once again for sharing your "craft" - awesome stuff!

:heart: Gorgeous custom mill :D

I'm pretty sure this is the same length as the 32nd motors by Avant Slot, NSR etc and some are run anglewinder.

Depending on body shape with the heavy detailed rtr interiors & LeMans styling.

They also make them with the cooling/inspection hole like the slot motors have Paul.
