Any of you guys that are looking at the 4.5's, I have my original 4400 (same as 4.5) system that I'd sell for just a few bucks more than what you are getting the reman's from them. It's been my backup system for the last couple years, but I no longer have anything that it will power (all 1/8th scale). Its got the 5mm shaft conversion on it.

i would buy a ballistic 550 around 5000kv

The HV4400 is a 6.5 turn motor, not a 4.5 turn motor.

It was rated at 4400Kv because of the bonded rotor that came in the original HV motor.

Thanks Novak!
 

The formal release on these systems for the Ofna Short Course vehicle will be going out soon.

These are offered strictly for 2S racing, but they seem to be doing quite well. We discontinued our 4.5 HV Pro motors because they were never advised for racing apps but customers kept racing them and burning them up anyway. Any 4.5 wind 550 size (5000Kv) motors we sell in the future will probably be on-line only.

We are "resuscitating" our Ballistic 550 project; so many projects, so little time. We are still back-ordered on our 540 Ballistics...

When we discontinued the 4.5 HV Pro motors, we took back a lot of them from distributors---we are goods guys.:lol:

So, we had all of these 4.5s in our motor mfg department collecting dust. Then Jay Halsey and Bob started looking for some system for the Ofna SC and decided on the Havoc Pro/ HV 4.5 Pro motor. They seem to be doing well with this combo.

This is why we are combo-ing this up for sale. We OEM these 2S Combos to NitroHouse. Many of the other SC vehicles do not seem to have room for this longer 550 motor, so this may be a limited market, but this set-up seems to be winning races.

We can always reactivate the store listing if we see a demand.

The high torque and cool running on 2S makes the HV4.5 the ideal 4WD 1/10 scale SC motor. I have one in my Jammin SCRT10 and one on the way for my Slash 4x4. Not certain how a Ballistic 550 would compare, but if you need a tester...;)

Post your experience of mounting the HV motor in your Slash 4x4; I thought the motors would be too long.

Where are you located?

the HV motors fit great with no mods needed:yes:

larger motors, such as CC/tekin, also fit good:wink:

my experiences with a 4.5hv is that gearing is not an issue anymore, I could put any pinion I had on and it would still stay cool(less warranty work:wink:).

my 6.5 just came today. I will be putting it in my slash 4x4 until my scrt10 comes. Then I think it will be time to sell a slash P.E roller.

Let me know when you do!

I always thought 4s was too much for that wind, on 2s i see where it can run lots better. With the larger size of the sc trucks (even the 2wd's), i see where the hv motors will be good. I didn't want my last post here to say i hated Novak, I started with them and like them to this day, Just thought the hv was slightly over it's head in the MT wars

novaktwo, you mentioned a ballistic 550 on rctech, i'm looking for something to replace my 5700 after it burns up in my hyper 10sc, eta?

We originally developed the 550 motor for the E-Maxx, long before there was any 1/8th racing. Once guys wanted to race 1/8th electric, these motors were simply overpowered. This is why we discontinued the 4.5 version HV. The 4.5s work great on 2S in the 4x4s.

We will probably announce the Ballistic 550s soon. We are doing some additional tooling, so shipping will depend on getting all parts in house.

Jeff, I'm pretty sure they run the 3mm shaft though. I looked at em but dont know if I would want the torque of a 4.5 in my SC with that small shaft. You know better than me though.

We originally built our HVs with the standard 3mm shaft, but redesigned the rotor featuring the 5mm shaft size; the 3mm was not beefy enough for heavier vehicles. Our HV 550s are priced at 99.99.

I was speaking of the Trinity motor. I have your 4.5HV and it is perfection in 4wd SC! Thanks for bringing it back. What will be different with the 550 ballistics? I have never used one. Is it mainly the ability to rebbuild with different winds and rotor?

The performance should be pretty much the same; it will allow the same timing adjustments as our 540 Ballistic (in fact, both motors use the same back end bell, bearing, and timing parts. Also, the shielded replacement harnesses and sealed socket.

We make "Frankenstein" 550s by adding the Ballistic parts listed above to our HV 550s. Here is the exploded view of our 540 Ballistic:

Novak Ballistic Motor

We can offer 550 replacement parts including wound stators, which may not be as easily damaged as the 540 stators.

We now have HV 550 motors in our store for use in the 4x4 SC vehicles. ROAR has determined that only 540 size motors will be legal when competing in ROAR-sanctioned SC races.

Many SC racers, especially here in CA, seem to prefer using the 4.5T HV550s. So we have added this item back into the store with a new description and listing:

HV4.5 Short Course 550-Size Brushless Motor -- 2S

You still have the words "electric 1/8th-scale" in that listing. I thought you were going to discourage use of the HV4.5 for electric 1/8th scale because of all the people burning them up in that application.

Good catch!! The burning up occurred in racing, but I want to have these references edited. We are going to add a disclaimer to all of our old product listings that include the HV 550 that the motor can not be run in ROAR-sanctioned events.

I tried to make the distinction between "using" these products in 1:8 vehicles and "racing" them. Customers will continue to install these products, and many are using them sucessfully in certain 1:8 events; we want to make it clear that they should not be raced (and cannot "legally"). The 4.5 set-up was the primary problem so we removed it from distribution.

Here's what I'm curious about, why state that the 4.5 can only be ran on 2s now? Just a couple months ago you were selling it as a 4s motor. I can understand kicking it back to 3s. But the 5.5 is still being marketed as a 4s, and it's rpm's would be around the same as the 4.5 on 3s. So it seems you are now being cautious to a fault. It also seems that it was the esc that had a much higher failure rate with the 4.5, then the motor itself. Does this play into the 2s rating?

I'm gonna try the new SC HV4.5 motor with my old GTB ESC. Anybody see any problems with that? I will be putting this in a Slash 4x4 PE. Not sure what pinion to start with - a 12 maybe? This would be for racing on a fairly large track. I need to stay up with the Jammins running the 4.5s.

Gotta try something - the Velineon with a 16 pinion comes off too hot when trying to stay up with the HV4.5s. Normally low 190s after 5-7 mins - can't even run any practice :oh:

the 4.5 HV hits 74K+ RPMS, most motors would not be able to take that for extended periods of time...

teh 4.5 sounds like a jet engine on 4s, throw in some worn down 32p gears and it just sounds nasty:bad:

My 4.5 has never had any trouble on 4s. It is the smaller shaft, but I've had it for over 2 years, it has always performed flawless. By the time you throw a load on the motor, it's much closer to 4000kv. I think what people don't think about is the smaller rotor does not create the same forces as a larger rotor motor would.

No problem running the HV 550 with our GTBs on 2S; in fact, the system we OEM for the Ofna 4x4 is comprised of our Havoc Pro and our HV 4.5 motor. The Havoc Pro is an upgraded (software) version of the GTB, with the same on-resistance as the older escs.

You could always run the HV motors with our GTBs on 2S---we just never promoted this use.

I'm not sure what all factors played into our decision to take the 4.5 systems out of distr. Once 1:8 racing began, it was obvious that the 4.5 systems were the most problematical (and the most popular...)

Racers who know how to set up their equipment for 4S usage have gotten many years of use out of these products; however, guys that don't take the time to set-up/use it properly create the most criticism and complaints. Telling customers that they are "boneheads" isn't an option....:lol:

So, in re-launching the HV 550 for 2S short course (4x4), we only emphasize this new use. If any of you have been following the ROAR thread on RCTech (Off-Road), you can read just how Novak is getting the cr@p beat out of us for even offering this 550 for the 4x4 trucks---ROAR has ruled that only 540 motors are legal.

I have read the section on rctech. Just glad that my track doesn't restrict us to the smaller motors in mod sct. Hopefully they will change the rule soon as they did with almost every rule that was first listed for 4wd sct.

540 motors in race conditions with a 6+ pound truck. :neutral: Really just asking for burnt up motors unless you gear way down.

I for one didn't think I would ever buy an hv motor again but they are perfect for 4x4 sct's. I am running a 6.5hv now for a small (75x45) track and will probably get a 4.5hv for the outdoor season.

If we can only wait long enough......:party:

...it gets popular.

We took our Sentry Data Loggers out of distr and lately have seen a resurgence in their popularity, for use with timing escs. It was just before its time!

Years ago we developed the Pit Wizard---hand-held programmer for the Cyclone escs. It was pretty much a flop! Or, again just before its time!

What's the difference between the existing HV motors and the new Ballistic 550 motors?

ballistic motors have replaceable stators. they are also easier to adjust the timing on the endbell.

So your saying the Ballistic 550 will just be a longer version of their 540 Ballistic motor?

yeah a 550 is just a longer can.

A poster on another forum asked about the performance differences between the 2 size motors:

Since the HV 550 motor has a stator and rotor magnet that are twice the length of a 540 motor, it will have twice the torque of an equivalent Kv 540 motor.

HV 4.5 550 (5000Kv)
Bal. 8.5 540 (5000Kv)

Therefore, if you are running two motors (one 540, one 550) with equivalent Kv in the same vehicle under equal driving conditions, the 550 motor will only have to work about half as hard and will heat up about half as much as the smaller motor.

I am responding to a racer (on RCTech) who burned up our Ballistic 8.5 in a 4x4 SC installation. Our warranty does not cover burnt motors or stators; but, both ROAR and 540 motor sellers (including Traxxas!!) promote the smaller 540 motor for use in the heavier 4x4 trucks.

Customers are really not happy with motor companies when their motors burn up.....:cry:

Companies are also not happy informing customers they're not getting a free motor/stator replacement....

I never burnt up a novak 540 but my 8.5 ran very hot in my 4x4 sct. Now I am running a 6.5hv and love how cool the motor runs. Might have to pick up the 4.5 for the outdoor season though. Any time frame for the ballistic 550's?

Since the Ballistic 550s use many of the same parts as our Bal 540s and our HV 550s, we are simply waiting for the black front end bells and some labels and we're good to go. The PRs can't be done until we can do photos/packaging with the missing items.

We have assembled a few 550 FrankenMotors from spare parts for visual samples and testing. This project became far more urgent with the 4x4 SCT interest...:yipi:

We will probably release three Ballistic 550 motors 4.5, 5.5 and 6.5. However, we can add additional replacement wound stators in the winds (Kvs) customers want. So, what do you think they will want? Any interest in 3.5 Ballistic 550 motor?

3.5 for me!

I'm not too crazy with the speedpassion one.

can't wait til my 540's burn up so i can order one of these ballistic's :lol:
