I finally found a Novak HV 4.5 and it is perfect in my Jammin SCRT10 on 2s. So yes there is definitely a market/need for 550 sized motor with high KV's (5000 or so). With the release of the 1/10 Ofna, Jammin and Traxxas 4x4 SC trucks I believe there will be a high demand for a high powered, cool running 550 sized motors for these trucks

Yeah, Novak would have the market cornered. They are the only ones I can think of that maded a 550 sized motor in a high kv configuration. They were originally designed for the big heavy E-maxx monster trucks and didn't work so well using high voltage lipo batteries (4s). But they are perfect in a 1/10 4wd SC truck which can run them and these motors have plenty of power, tons of torque, run ice cold, very forgiving regarding gearing and put out enough rpm's (because of the high kv) to run on 2s lipo which most tracks require for racing. Castle and Tekin do not make high kv 550 size motors. Unfortunetly Novak has discountunued the HV 4.5 (which was the only high kv version) and now they are hard to find. Novak please bring back the high kv 550 motor.... I have one in my Jammin SCRT10 but I need another one for my Traxxas Slash PE 4x4..

Didn't think I would ever need a high rpm 550 size motor again. My slash 4x4 and scrt10 (on the way) changed that. Just ordered one of your rmf 6.5's.

I'd say that the 4wd corr trucks will definitly make the 550 motor sizes important going forward. Would certainly be worth while for Novak to pursue.

Another option that is currently out there for the 550 size motor is the trinity Duo 550. They have 4.5, 5.5 and 6.5 motors for around $99 and are in stock on amain.


I can't decide if its more fun
to make it...
or break it...

I ordered the rmf 6.5 from novak. $65 plus shipping, came to $72.xx. I am only running on a smaller (75x75) indoor track. My tekin 9.5 was fast enough in the truck but ran to hot so I figure the bigger can will help.

Well if you'll would have listened to me when I said they would do great in the Slash, you would have already had your motors :p (please note my first post on 11/20)

I know it will be a beast, but I'm still planning on 4s with my 4.5. If it's just to much, I'll kick it back to 3.

nitrohouse.com has the HV4.5 in stock. Like you, I have one in my SCRT10 with MMPro on 2S and love it. Just ordered another one for Slash PE. Tried running the Ballistic 8.5 (5,000 Kv) but it got too hot too quick. Hope the HV fits ;)

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.

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.

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...
