Novak Ballistic 8 2D Review
 
First impression was excellent when I opened up the packaging. Once you have the motor in your hand, you know why it cost so much. Built quality, fitment and final assembly is top notch. Dare I say Hacker, Lehner, Pletty, LRP quality? I looked hard for any fault and couldnít see any.

Well you guys should know me by now. I had to open up the motor and see for myself were my money went. It was easy to disassemble. There were 2 shimmies in the front and a fiber shield to protect the windings from long screws. The sensor board was easily removed as well. The sensor wire/port shield was the only plastic part. When I unscrewed it, one ear broke. Upon reassembly the second ear broke. Pretty crappy plastic if you ask me. It should have been made out of metal instead. A small sensor wire was included.

The winding on the stator were nice. Itís listed as 12 slot, 4 pole motor. The rear of the stator has some sort epoxy. Iím assuming high temp stuff.

The 4 pole motor is Kevlar wrapped and drill balanced like some other high end motors. The wrapping didnít go all the way through the rear of the rotor though. I figure you donít need to do the whole rotor, as the damage usually happens from the front.

My test vehicle is the GTP geared 47-19, with the diffs being 44-14. Batteries were my best GenAce 4s1p 40C pack that I had. This battery had only seen light duty in my ebike since it was new. So it basically had the proper cycling and 4.1V per cell max. ESC is the RX8, EC5 connectors, and 6mm motor connectors. Tires were GRPís.
I only ran it for half a pack up and down the street. Did some burnouts, speed runs, simulated a race on a track and got the motor to 178F when I was done. Temps would have been lower if had used the current limiter when doing the hard stop and go scenarios.
Iíve used 2343mah. Peak 2336W@12.7V. Contiuous power was 952W, 61.03A, 15.6V. I calculated the speed to be in the mid 50ís and it sure looked like it.

So far Novak has only two windings available. But in their little booklet thingy in the box, more windings are listed. I hope they get to those quickly. I really like this motor and it's worth the high price.

That looks like a healthy motor. thanks for the review and opening it up. Any info on the temp?

snellemin 10.26.2011 10:59 AM

I listed the temp above. The motor temp was at 178F with me jabbing on the throttle like a monkey and gearing. Temps would've been lower with a 18T pinion.

Snell- Thank you for the review. I always know your reviews will be thorough and that you will really push the motor to see it's true capabilities. You are a great asset to this community.

And the one shot of hand porn will get me through the weekend:lol::na:

so quick question, how does it compare to the viper motor?

snellemin 10.26.2011 09:08 PM

Viper doesn't even come close. Remember that the viper is just a oversized 1/10 roar motor. Anyways, the Viper had been recalled and they are doing a 4 pole version.

I always enjoy a motor review from you Snell. I used to love collecting motors and comparing them, but you go all the way with the data logging and have some great test vehicles. Nice to see novak catching up...

All we need now are some sensored outrunners...

snellemin 10.28.2011 01:31 PM

Thanks James. I like messing with new stuff when the budget allows.

Novak is the only one that really brought something new to the 1/8 motor world recently. They gave you the choice of swapping out stators, which keeps the cost down when wanting to experiment with different kv's. The motor noise is also unique with this one.

I'm going to buy me a small 60fps hd camera, so I record my tests.

Thanks Sellemin for the nice review. You did a very professional job. I personally did a lot of work on this project. We wanted to follow our Ballistic pattern of completely rebuildable motors. It is not an easy task hand winding 12 slot stators. I had to design a lot of tooling to do the winding, compressing, resin impregnating and soldering of these motors. The rotor was also a challenge to make sure it would survive the rigors of 1/8 scale racing. As you can see by looking at the rotor the alluminum end caps are keyed to the shaft and the magnet segments are keyed to the end caps so that there is no possibility of slippage. The magnets are then magnetized in house and then wound with Kevlar thread on another piece of machinery that we designed here. This whole assembly is then epoxied and drill balanced on both ends (if necessary). The Ballistic 8 motor then goes thru a series of extensive test to assure the best quality that we can.

Thanks Bob, for adding more info regarding the rotor. When will the other stators be available?

I hope Monster Mike adds these to the store.

fastbaja5b 11.15.2011 11:15 PM

I always thought 178f was way too high, and that a good motor shouldn't approach that no matter what you do, but then again a few racers say that LRP X12 17.5's like to be run hot (180-195f), is this a trend with new motors now, higher heat tolerance?

snellemin 11.15.2011 11:43 PM

Novak list a max of 175F for the Ballistic 8.

snellemin 11.17.2011 05:08 PM

Vid of the Novak motor in action. I got the motor up to 206F when the vid was done.
