Mine does that too you need to take readings with the rotor moving. The lowest reading you get while you turn the rotor slowly.

{a minute later}

Crap...you got me thinking. Was it 0.0 or somthing else...hmm...if i unsolder the motor wires and leave it in the car......

Do you know if this will be sold as part of a system? Or just the motor?

I've only seen it as a motor.But not sure on Novak's future plan's.

This year's Indoor Champs at Cleveland will be VERY interesting, as they are allowing BRUSHLESS motors (manufacturers subject to Mr. Bills aproval) to run in the mod classes, along with the brushed. I know at last years Halloween Classic at the Gate, Barry Baker was running a BL motor during the open practice sessions, and the car was faster than with his 'team' brushed motor. So, what will the top dogs in mod classes be running this year at the Champs?

Default 13.5 Test Results

Just got my 13.5 yesterday. Tried it at the track today. I was kind of disappointed with the results. (at least for this first day of testing) It was pretty slow. I was getting passes on the straight and it did not have the punch that I have seen in novak's other brushless motors. I do have to admit that I did not have time to work with the gearing, but I was using a 7.33 : 1 ratio.

I used a 7.0 : 1 ratio with a SS4300 the past year and that seemed more like a very good 27t.

We'll see, haven't given up yet. I might just get the velociti 3.5 and race mod; love that power and speed.

You were under geared. The 13.5 has more torque and less rpm then a 4300 (10.5). Gear it up and it should be as fast as a good 27T motor.

Yea, it's 3 full turns lower than a 4300 (10.5T) so it's going to be slower. Most people seem to think it's right on track with a fast 27T when geared properly.

So, where's a good place to start gearing this thing? I generally speak rollout since we're on foams, but I can figure out ratio too.

The magnets in the 13.5 feel much stronger than the 4300 when I turn them by hand. The 13.5 feels a lot more like a brushed motor with a lot of magnetic resistance, where the 4300, 5800, etc. are very free and smooth. Is this because of the increased wire mass inside the cans with the additional turns? I'm guessing this is the same rotor as the upgraded one in my 4300, and not one that was specially designed for the 13.5. I say that because supposedly you can used the sintered rotor in the 13.5, and I don't see one for sale specifically for that motor.

The 13.5 comes with the older style endbell and rotor, like the 4300 and 5800. This means it can't take the sintered rotor, but probably can take the SS upgrade kit, and then in turn take the sintered rotor.

Obviously, since it's tuned with being true to stock in mind, you wouldn't want to make these changes. Just an FYI though, I hadn't seen it mentioned elsewhere.

Well, I have only run it on rubber tyres outdoor on asphalt - to see the track go to www.wlrc.co.uk - straight is about 110ft and track length is around 700ft depending on track layout.
My normal Monster gearing is 6.0:1 = 33mpr.
On the 13.5 I am at 5.6:1 = 35.3mpr

Ran the 13.5 tonight. Man, that thing wants some gear. I ran out of pinions after I put a 40 on there, and it was still under 130 degrees and clearly ready for more. Even at that gearing (rollout around 32.5mm) I was real close to the other guys. My batteries aren't the newest, and I could definitely give it more gear, but I wasn't at much of a disadvantage. Other people watching said it had a bit more rip out of the corners than some of the other guys, but I imagine gearing it up will cut that down and help with top speed, where I was maybe just a tiny bit off.

I do believe Novak has a winner. For club racing, at least, my initial impression is that the 13.5 should be readily allowed in stock class for the guys interested in running it.

Now that you tested the motor and found the same thing I did.As I have said this is the way to go. Now it's time to get rid of my old equipment for a brushed motor.Just curious where do you get those numbers.Are there any charts and how do you use them? We run rubber tires down here.

I have run mine twice this week. Once indoor on a tightish track at 6.19 on 63mm rubbers and would have liked to try 5.95. Today outdoror on a medium sized track and at 5.16 it was close to the best Co27's around here - not making over 120 degree at the end of the race. I'm very happy with it - will continue testing but think it's the future for sure.

Do you think the GTB will need the fan when running with the 13.5? What about the 4300? I ran without it at times, and it seemed to do just fine.
For what it's worth, I run my GTB as my only stock ESC on good CO27 motors (or any motor) without the fan and it barely gets warm (115 - 125F in warm to hot days) on a med-large ashphalt track with some tight turns and fast sections. So should be OK if the 13.5 is 27t equiv current. Also, running the 4.5 brushless it came with, my fan blades finally slowly all died off and I was faced with trying to run a large oval dirt race with my T3 truck. Got good advice to cut a cooling vent flap in the side of the truck and GTB temped at 165 after a 8-9 minute race, just below the thermal point. 4300... well might be ok, depends on how it's used... also Novak claims the fan increases efficiency however I imagine that's probably more true for the low turn BL motors like 5.5, 4.5.

Another suggestion, you can always call Novak tech support to ask questions. I had slow time getting through but was pleased with the technical understanding and answers I got.
