The reason why I ask is that the brushless will be run at around 10-10.5 from what I'm told and everything else I run requires a bigger pinion. I guess I better leave myself some room.

Slam, what they're talking about with the 70/30% is the balance of the overall trigger movement. That has nothing to do with the end point adjustment. I think all of your higher end radios are set to 70:30 by default. So if you haven't changed your throttle/brake balance, don't worry about it.

So I think I have a little problem. I sent Charlie an email, but this being a holiday, I don't think I will get a response very soon.

I've got a 6.5 and a 5.5, both used, but neither has been ran by me. I don't even know if either works, but my esc doesn't do anything above 6.5, and I'm afraid to try the 6.5 due to the following problem.

The 5.5 spins very freely, like I would expect from it. In my experience, brushless motors spin more freely than brushed motors.

The 6.5 spins like it doesn't even have bearings. It feels kind of like my 12x2, but even harder to turn, like it has grease in it or something.

I've taken them both apart, the bearings are all great, spin very freely and smoothly. I've tried switching the armatures, the 6.5 still spins poorly. To me, they both appear identical inside, but I guess something must be rubbing.

Does anyone have any ideas as to what might be wrong?

Anyone know where I could find a schematic of these motors so I can make sure they are aseembled properly?

Thanks!

i guess theres something wrong with it. try blowing air into the can and check if theres some shims left behind. mine works fine rotates freely. btw how did you check the bearing on the bottom of the can? did you remove the armature? i only clean the outer bearing that is exposed.

is this a used motor that you bought?it sounds like the motor melted down and the winds are loose and rubbing the rotor.i have seen this happen in a 5800 that was geared like a reedy quad mag.not a good idea.

HVAC, try loosening the endbell screws a little bit at a time and see if that helps. They may be too tight causing the endbell to deform. That'll make it bind every time. Other than that, send it to Charlie...

Slam, no problem. Glad I could help.

Just so you guys know, I answered all 3 questions asked of me in my first post... But I will again.

Yeah, I checked the rear bearings as well. Yes, I removed the armature. Yes, it's the used motor that I bought.

To my eye, it doesn't look like there is anything different inside the 2 motors. If something is rubbing, which it must be, I certainly can't find it.

sounds definitely like a shorted winding in the motor... this will make the motor feel as if its braking much like when you apply the brake on your radio. The rotor just doesn't spin freely, like you said. Also the faster you try to spin it the more it seems to resist spinning. not much you can do about it but send in for service.

Excellent. Screwed, as usual.


Anyone in San Diego have a used 6.5, that actually works, that they would like to sell me?

Found this on Tower's site.

http://www2.towerhobbies.com/cgi-bin...?&I=LXNJA2&P=7

Novak's site lists nothing. Anyone have any word on this? That would be awesome if they do perform just like brushed stocks, and ROAR approves these.

Although the price is a little bit steep, hopefully once they're out prices drop quite a bit to the $60-$70 range of the current BL motors.

4.5R (4.5 turns)

Here's some info from Novak's site:

Crawler 18.5 (w/Crawler ESC)

This price list mentions the 13.5, but the link goes to the page for the 4300. I wonder if the 4300 is being replaced?

Actually, here's the info page for the 13.5.

Now, before anybody gets their panties twisted, all this info was found by simply searching for a few keywords on Google.
