Yes, the heli motor will be 6mm, and the truck motor 5mm. It should have been that way from the beginning -- was an oversight on my part.

I'll have to get back to you on the bearing size - - working at home today (sick kids...)

Once we have the 5mm shaft in production, we'll offer a replacement rotor to those who got a 6mm and need a 5mm instead.

Good stuff, but will you swap out for the ones that were "modded" to 5mm...? Nothing against my skill, but I would much rather have a properly turned shaft than my half-assed attempt!!!!!

Sure -- but it will be about 6 weeks before I have 'em here.

No prob, I will most likely run this as is, see how it does. Thanks for taking care of us, means alot to me at least!

Yes, thanks Patrick! Would it be a core swap, or would you have us 6 mm guys just ship back the old motor?

+1, a new rotor would sure be nice. Very nice gesture and much appreciated.

I got my 1512 1.5y today, here are some pictures http://i629.photobucket.com/albums/u...g?t=1261013929http://i629.photobucket.com/albums/u...g?t=1261014011http://i629.photobucket.com/albums/u...g?t=1261014054

thankyou

I got a 6x16x5 bearing for mine and just an FYI is is the WRONG size. I need to measure mine again and order another bearing, this motor is proving to be a pain in the ass.

EDIT: Measure twice, buy once. it's 6x17x6. Boca has a good selection of them, should hold up as well or better than the stock one anyway.

I finally got mine today. Post office beat up the shipping box pretty good.

1520 vs C40 hacker.

As far as mounting, I bought a Tungsten Carbide cutter for my Dremel (Part number 9903) and it made mince-meat of my RC-M motor mount. I widened the channels to accept the 4mm screws in about 30 seconds then spent a minute or two smoothing it out and it came out great.

Mounting in a Muggy is a piece of cake and there is plenty of room for gearing. There's still space between the motor and chassis and I can push the motor all the way into the chassis brace and have the rotor so close you could probably put a 9T pinion (or maybe smaller) on it and not have an issue. Can't speak for other 1/8th scales but with a quick bit of Dremelling on the mount it mounts up very well. I'm glad they put 4mm mounting screws on this motor, it's heavy enough that the extra strength may come in handy.

Glad to hear it was a success :yes: And looks great !

Anyone know what the max rpm on 1520 is?

Mine says 60K max on the endbell.

It looks great U Spy! Nice work with the dremel.

So has anyone had a chance to actually run this motor? I know it's 45k max, but is it fast enough?

I have here is some Video of it in my Project: Savage X-17

It all depends on your gearing. This motor should be able to pull some crazy (1/8 scale) gear ratios.
Assuming the esc and lipos can handle it.

That looks really cool Bruce! I like the center diff especially!:yes:

Is it fast enough? Most here run about 35-40k rpms on their MT setups. I have run motors closer to 50k for lighter vehicles, 10th scale and 1/8 buggies, but those motors were smaller/lighter...

Holding it in my hand I have a feeling it will easily eclipse the power my neu 1521 1y on 6s puts down. That is a 1600kv motor on 6s, so not beating 40k rpms... The 1717 will have more torque than the 1521, but may spool up slightly slower. I have a feeling it will really weed out the crap lipos though, hope the 40c zippies can keep up.

I need to get suspension back under my lst and give this bad boy a try, My 2nd tdr mount came in, and this one has the m4 sized front plate so I can run my 1717 without the rcm thread adapter plate. I will get it together at work tomorrow and post some pics of the motor correctly mounted with the new tdr plate and the 25/63 gearing.

Hope to have the battery tray made up and the truck running by christmas!

I got my bearing in from Boca and now it seems I borked a CD bearing, but I ran it anyway. Pretty sure the can is too big to allow for my 14T pinion, so I slid on a 16T just so I could run it (geared for 60 MPH before ballooning). Accelerated my ~14 pound Muggy to top speed as fast as the tires would allow and in the 3 minutes that the pinion stayed on the shaft it never got even noticeably warm (running without a body). Seems like the perfect motor for my Muggy, but I'll have to wait until Summer to see if I need to mod it to take a bigger spur because there's no way I can gear it down to 45 with those tires and the stock spur.

I got some video, it's kinda crappy but it works. I have no internet at home right now, but hopefully I can netstumble upon some sucker who thinks WEP is "good enough" and get the video up.

Any word when I could send my motor back and get the 5mm shaft version? It's still in the box and I never had power run through it yet...

the snow on the ground really wont let it perform it seems, i think when i have the money ill put the 1520 in mine as i want more gearing options but ill have to buy a new chassis plate as mine still resembles a taco. nice vid looks cold out there. really makes me want to get mine out again.

Yeah the snow wouldn't let it hook up very well but the power is insane. It was around 0 that night, but I really wanted to run it!

If it has any power like my 2250 had.
It is a awesome and fun motor.

great looking motors......

which battery is the best for 6s full high speed motor?

Too vague.

What truck and motor do you have exactly?
What speed are you aiming for roughly?
How much money do you have to spend on lipos & charging equipment?

How much experience of BL and high end r/cs do you have?

Answer that little lot then we'll be able to make some proper recommendations...

What would people think about 1717 on 4s lip?

1580kv on 4s will be rather slow, needs a bit more voltage to unleash its potential I would say.

IMO, alot of it really comes down to available gearing options.

Neil, you are right about unleashing it's full potential, But........

Even on 4S, such a well built motor can really perform.

Example:

I just picked up another Heli motor. I have an obsession with outrunner type motors, thus the reason for the avatar.

This one is HUGE. 43mm X 72mm. It is a 8 pole outrunner that yields 1100kv.

It's stator is 35mm in dia. X 38mm Long. Very strong magnets.

The advertised rating is 1600 watts continuous and 6S.

The Thing is a Torque Monster.

I've only ran it once so far on 4S, but in an E Revo geared 25/36 using Mod 1 gears, It is very impressive.

No Cogging and it will backflip. LOL It runs really cool too.

1st run was cut short when the Motor Pinion came loose. This time it got some Blue Lock Tight.

Back on Topic, the 1717 looks to be VERY well built. I can see one of those in my future.

I see alot of talk about Maximum RPM's, but you gotta realize just how much torque the lower kv motors are capable of.

How high it winds becomes less of a performance factor, the larger the motors get. :yes:

when i first got into this everyone was buying the really high kv motors and puting and running them to the rpm limit causing hot setups. now its the monster max and a low kv motor that runs cool and efficient. im really enjoying this new stuff as it comes out.

I tried a 1280 kv motor on 6s.
It kind of surprised me.
I figured even on stock gearing it should run faster.
Alot more pep to. :D
On an emaxx machine :)

Nice video Un.Spy! That 1717 is a bad boy!

Thanks, unfortunately that truck was stolen a few weeks back :(

Are all the new truck-specific motors shipping with 5mm shafts? I'm in the market for a replacement truck but would like to run the MMM with a 1717 again.

Someone stole your muggy? how did that happen?

Sullied,
Bro, Really sorry to hear some dirty scum bag Mother F'er stole your RC. Hope you find whom did this and they get whats coming to them ?

Castle,
I too would like to know about the 5mm shaft availibilty for the newer 1717's ??????

Fooking Scum! That blows Spy!

Well if a 1717 with a custom shaft shows up anywhere in your tri-state area chances are good it was yours.

I'm pretty sure the new ones will be 5mm.

Yeah, really sucks. My shotgun and shovel are ready if anyone knows who has it....
