Ballistic 550's a reality
 

Looks like Novak is making the 550 a ballistic motor, Wonder if they will offer anything in a 2500kv equiv.

Saw that on rccaraction and redrc. This should be great for the guys running 4x4 sct's. I have been running there 6.5 hv in my jammin for a month or so and it works great. Might still pick up one of these in a lower turn for the outdoor season.

Can someone please clarify what the watt rating of the motors tells me?

The 5.5 turn ballistics 550 motor is rated at 800 watts and a 13.5 ballistics 540 motor is rated at 195 watts. So does that mean:

...that its going to drain the battery 4x quicker when I'm WOT vs ballistics 13.5

...that there 4x the torque throughout the entire power band vs a ballistics 13.5? Insane acceleration?

Can you use this motor in a MMP?

Please enlighten me...I'm stumped...

NO,
That means that the motor can handle more power IF IT HAS TO....
You will probably use only 400 or 500watts but with more efficiency, so for the same top speed, you should have same runtime...

In addition to the optional 7.5 wound stator, we can also offer whatever other winds customers want to use.

Such as 8.5, and maybe 3.5.

You don't use more power than it takes to run the car.

Example: I ran a HV4.5 powered Slash 4X4 13 minutes (until the truck slowed down) on an off-road track using a 4500 mAHr LiFe (Turnigy pack). So my average amp draw was 4.5 / (13/60) = 20.7 amps. The average pack voltage (I know from discharging the LiFes at 20 amps) was about 6.3V. So, on average, the motor was using 131 watts.

I was using a MMP and you can too.

so why would I want to go get a 550 motor instead of sticking with a 540 motor? If I'm going to average using 200 watts, is there any point in going with a 550 motor that I can't get 800 watts out of?

You wouldn't if you were running a 3.5 pound 1/10th scale buggy or truck. (Well, you probably wouldn't.)

But in a 5.8 pound SCT, a 550 has an easier time of it, and runs cooler, than a 540 motor. Lots of people are seeing temps around 170 to 180 using the 540 motors in a SCT. The HV motors run around 120-140 with reasonable gearing and will just last longer because of that.

Also note that the 800 watt rating is a peak power output for an unspecified (by Novak) period of time.

We will begin shipping the Ballistic 550s to our distributors later this week.

Any word on getting the lower kv winds into the lineup? If you had one at around 1800-2200kv I would love to try it out in my buggy. The only thing keeping me from trying the HV motors or new 550 Ballistics is the higher kv rating.

Winding stators for the completed motors we are shipping is our highest priority right now, but we will be adding replacement wound stators to store inventory soon. I just emailed manufacturing to see if we can add a few of this lower Kv replacement.

We should have these Ballistic 550 replacement wound stators (8.5 wind) in our store inventory in a week to 10 days.

Hey, I have the same combination. but haven't been able to drive it on a track yet.
What pinion and ESC / ESC-settings are you using?

Do you have an idea of what the approximate kv rating the 8.5 wind will be?

I'll check and see if we have a Kv for the 8.5, yet

Larger motors produce more torque.

a local indoor offroad track is letting 1/8 run on a tight track but is limiting voltage to 2s, so i was thinking of trying one of the new ballistic 550's in a rc8 to try to compensate, would this work?

From our testing the Ballistic 550s work great in 1:8 scale on a tight track on 2S with a standard 1/10 controller.

thanks!! just ordered a 5.5

Bob is winding both (550) 8.5s and 9.5s to get closest to the Kvs requested. I'll post the Kvs when he tells me.

Good to hear about the 8.5. What about the 3.5?

I'm pretty sure that we will have a 3.5 replacement stator for the 550. These are repl stators (only) that I am describing. Actually, we can wind a few of any wind, like we do with the 540s. We even offer "light" stators for the 540s; although. I'm not sure anyone has ever ordered one.....

I really wish kV/Turns were standardized, like;

(I know these are way off, but it shows what I mean)
2.0T=12,000kV
2.5T=11,500kV
3.0T=11,000kV
3.5T=10,500kV
4.0T=10,000kV
4.5T=9,500kV
5.0T=9,000kV
5.5T=8,500kV
6.0T=8,000kV
6.5T=7,500kV
7.0T=7,000kV
7.5T=6,500kV
8.0T=6,000kV
8.5T=5,500kV
9.0T=5,000kV
9.5T=4,500kV
10.0T=4,000kV
10.5T=3,500kV
11.0T=3,000kV
10.5T=2,500kV
10.0T=2,000kV

I know that each size motor would have different numbers, but you get my point...I hope.

That would simplify things, but I don't think it is possible. Different manufacturers have different Kv readings for the same wind motors now. All of our Kv numbers are unloaded, so you would also need to know whether all the different companies measure the Kvs the same.

So If I wanted to get a 9.5T Ballistic 550 I'd have to buy one of the other already available complete motors and the replacement stator? I guess I could sell the original stator, but I'm not too keen on having to do that.

We will also be offering Build-A-Ballistic™ 550s later; this allows racers to customize a motor to their own liking. We will not offer as many options for the 550s (as the 540s) because we do not have as many choices. But you will be able to select:

~ wound stator, wind/Kv
~ rotor, standard or tuning
~ stainless steel or ceramic bearing (I think)
~ sensor harness length

This will cost somewhat more than the ready-built 550s; however, not as much as purchasing a motor and an extra wound stator.

I can deal with that! Ballistic 550, 9.5T stator, slightly larger diameter tuning rotor, ceramic bearings. I bet that would be great in my buggy, can't wait to try one.

Bob asked me last evening just what you guys plan to do with the low Kv Ballistic 550s; so, I'm asking....:wink:

He has wound, and measured, 3 different winds (verbal info):

8.5 @2500 Kv
9.5 2250 Kv
10.5 2000 Kv

So, how low does the Kv need to be? He said it could be a 11.5 before the Kv gets under 2000

He will be emailing me the actual numbers, but these should be pretty close.

I'm guessing people want to get up to 4s+ in either 4x4 SC or try using these again in 1/8th buggies...

That was my guess as well.

I'd be quite happy with anything 1800-2000kv, so the 10.5 or 11.5 is what I'd get for my 1/8 buggy running on 4S lipo.

Thanks for the inputs---I'll let him know.

It will go into my crt.5 and a buggy.

NovakTwo, how about asking Bob about this. IMO running these motors in a 1/8 buggy type setup, with a low KV value, 2000kv, or under, on 4s, will either run slow, or get to hot. I understand wanting such a KV, but from my experience with your motors, they do better making their power with rpm's and gearing lower, then gearing up, and having the motor pull more.

So I guess my question would be, what would be the ideal KV for a 1/8 scale buggy on 4s? Or at what KV range do the HV motors see the highest efficiency?

Good question; I have forwarded this to Bob and Adnan.

Busy day today; we are sponsoring two races this weekend at which we plan to do more Kinetic Havoc Pro SC Beta testing. One is the SC race at WCRC.

I'd like to know aswell. Been wondering the same thing.

I was thinking the same thing, because I had already wanted to try it in my buggy, and now I picked up a CRT .5 kit. I might buy the lower turn, higher kv wind to use in my CRT .5 because it will be available right away, then get the higher turn, lower kv wind stator when they become available.

Any input on this yet?

This is his response:

Those of you with more specific questions could email bob@teamnovak.com directly---cut out the middleman....:yes:

I have been wanting something like this in a 1/10 scale castle motor (2000-2700kv), on 2s lipo. My belief is, the motor kv is an indication of powerband, While they all make the same power, Theoretically, They make it at different places on the RPM spectrum. For instance, the HV 4.5 (5000kv) and the 10.5 (Roughly 2000kv), While both make the same power under load, The torque band will be lower in the lower kv motor. Plus with the lower kv motor, you have the headroom to raise the voltage and gain from the efficiency of using less amps over letting the voltage do the work

Almost forgot, My plan for one of these is in a CRT.5 on 5s geared for mid to upper 30's
