ARC Motors?

[ray schrauwen]

I would think a higher KV would get you there with smaller props, thats why I went for the 1 turn units. They are more efficient as well. It's just for giggles at the end of the race day or in between heats.

Nice looking motors. They could be very close to another well known motor we buy.

They look really nice Jeff, nice thick windings, rotor looks good too, no crap here.

Well iF these are from arcsystems in NY then I bet they are very well made. If China then they could still be ok.


There are a few forums with some info but a coulle said they smoked them.

These motors from what I've read a great, I used to order those himodel 200a looking esc's from Dave @lightflightrc, who sells the are motors. If you read his threads on rcgroups http://www.rcgroups.com/forums/showt...ight=36+mm+arc for the ARC 36mm, some of these motors are pulling 2800 watts plus on 6s to 9s

Look at this one guys test results from the Arc 36x55 2.5 1100kv .....2900+ watts @ 66+ amps on 12s, keep in mind these are ductfan setups. http://www.rcgroups.com/forums/showp...82&postcount=1

I have a 36-75-1 Arc motor in my hotr 32. Ran it today on 5s with a x445 in choppy water and it performed really well. I can compare it with my Feigao 12XL and the Arc pushes more watts and runs alot cooler.

The pinned backplate is not a problem, its only an issue with planes where the prop puts direct pressure on the motor. In boats the drive hardware (stinger or strut) takes the pressure which is not transfered to the motor.

I`m planning on 2 x 36-65-1 motors for my next project, a hotr 32 cat. I`ll let you know how I get on.

I don't know what driveline you are using but if it's an Octura or Hughey cable, you cannot put thrust onto the strut, otherwise the cable will bind up and snap.

All you need is a 5mm thrust bearing between the coupler and the motor face and leave a 1/16" gap (at the strut!) for cable shrink.

I'm considering an ARC 36-65-1 (2080KV) motor for my Whip20. Anyone try one of these in a 30" hydro?

Did you run these motors yet? What is the verdict?

Yes, and we will see how they work in a twin cat. I bought a pair of 36 55 -1T, they look like Neu 1409's with cooling holes.

Sorry Jim, this project won't be ready until spring or maybe sooner. If sooner I'll find soft water somewhere to test. Getting cold now.

I'm a slow poke builder...

It's a good thing you don't bring her to the races, you would win every race you entered!!

Seriously, you two look great together.

No one can believe you real age either John, you take good care of yourself obviously.

Would you believe she's 3 years older than me...............................
