I agree with the others that Novak products are for the most part too high KV. This new traxxas motor looks interesting too me because it is only 3400kv which is right on par with what I've found actually works well on a 2 or 3 cell pede. Traxxas's first brushless and already they got the KV correct right out of the gate. I think this says alot for Traxxas. In fact.....I'd say they are the first one's to actually get the KV even close too correct on a RTR RC. I would like to buy one of these motors and try running it with my MambaMax ESC. Lower KV motors with 1/8th shafts are rare as gold these days. This might turn out to be the perfect motor for rusty/pede regardless of which speed controller you are using.

Is traxxas going to finally ship the pede with wheel bearings? I don't see how they can run brushless and keep the bushings.

Yup and to add to the cold front through hades, they will be 5x11, No more RPM upgrades needed

Yeah, that plastic mount is a concern though;

Perpaps someone can make an inlay aluminum plate

Yeah, it looks like it just might get worn out from the screws in there. Plus there is not heat sinking action, the motor might run a little hotter than it could have with an alum plate. It does look generally rigid though, with the thick plastic ribbing on it.

Sweet!... so it's not plastic gears... that is awesome.. Sorry I have problems reading... I've been hit my RC cars too many times..

Wow, now 4 companies are battling to see who will come out with a nice HV brushless system: Traxxas, Novak, Castle Creations, and Tekin.... this will be interesting. :)

Serum · 05.27.2007, 04:43 PM

But novak completely misses the point in terms of KV; and they get hot due to that as well, so i think we can call that 'lesson learned' and a more reserved kv value will be used by novak as from now?

suicideneil · 05.27.2007, 05:01 PM

I do hope so Serum. I was comparing the specs of the HV range of motors:
6.5 = 3100kv = 44640 rpm = 14.4v = 500 watts
4400 = 4400kv (original one I have) = 63360 rpm = 14.4v = 375 watts
4.5 = 4800kv = 69120 rpm = 14.4v = 800 watts

Those figures are way too high on the HV4400 & HV4.5, no wonder they get so hot and suck the life out of my poor cheapo batteries. The 6.5 has potential though- 45,000 rpms isnt too bad on 14.4v, and it has much more power output in terms of torque due to the newer sintered rotor. There is a video or 2 on youtube of someone running their Emaxx on 16.8v with the 6.5, and it is rather quick. I know sensorless is way better and cheaper by-and-large, but if I could get a 6.5 motor for fairly cheap somewhere, I reckon it would make and ideal upgrade having more torque, lower kv and cooler temps as a result. Food for thought, seeing as I am a 'casual' user rather than hardcore racer/basher.

Woah, I wish I could do 70mph in my T4, I have a 5700kv motor and 20C 11.1v Liopos but it just won't get there like the diagram says, lol...

I suspect that you could get there if you were only gearing it for speed runs. I'm guessing that the reason the new traxxas stuff doesnt come geared like that right out of the box is cuz it wont run like that constantly either. Speed runs are entertaining, but you certainly cant set them up to run that all the time.

coolhandcountry · 05.27.2007, 09:56 PM

I think the 45 would be a nice out of box set up to run.
I think a nice step to brushless being more popular and more options.

Novak two, I started with a HV 4400 and loved it. While i have moved on to more powerful systems i think the 6.5 and 4.5 are good starter systems. There are two types of people here that i can see, Type 1, the one who has to have the latest and most powerful and willing to do what it takes to get it. Type 2, those (like me) that prefer baby steps and like to change as little as possible at one time (call it baby steps). I started with novak, because it programmed the same as my dually and EVX.

n/m...been drinking too much beer,, enjoy your holiday :)

Nice. The only bad thing I can see in all of this is that all of our custom brushless pedes and rustys are now worth half of whatever they were worth a week ago LOL. OH well. Just glad to see Traxxas kicking butt on the brushless side of things.

Same thing will happen to the E-Maxx and converted Revos if/when they release new electric versions.

You're right. It will be good for the hobby as a whole but some of use will take a big hit in value......however, if we keep our stuuf and keep running it it won't really matter!
