Default Hacker 10.5 vs Novak 10.5

I heard someone say that the Hacker is way faster. When I hear "WAY" that equals hype to me. I'de like to hear some real practical experiences if anyone has a/b'd these motors in the same car back to back. Just want to hear differences in torque, speed,maybe less heat, etc. Maybe there isn't any. Just curios. I have a Novak and the Hacker seems legit. Any comments?

Not sure about the 10.5 but, I recently bought the Hacker 13.5 and 17.5 expecting great things. I've done a fair bit of back to back testing against my Novaks, LRPs, and Trinity Duo's. The hackers are the weakest motors of the bunch on the track! I've tried every imaginable timing/gearing/speedo setup combo cause I didn't want to face the fact that I blew $150. Unless I've missed something?? Oh yea, and they seem to run hot too, not unusual to see 180 if they're geared at all. So.....IMO save your money bro!

Ive never had any of my hackers run over 130*. They run fairly cool, the hotter they run the slower they are. They are identical on the track to a duo. That was with stock timing for tc and full advance for 12th.

Wait a minute... what are you guys saying? Aren't all brushless motors supposed to be the same? Weren't we supposed to buy one motor, never do any maintenance, and be fast for life? What the heck happened?

more companies other than Novak started making motors

Didn't you know about it: Novak 10.5SS has 4200KV but Hacker 10.5 has just 3080KV.
That's why our organization only define classes with motors' KV, never with turns.

1. Hackers 10.5 is 3500KV/rpm, not 3080.

http://www.hackerbrushless.de/images...EB%2040+41.pdf

2. If you read the small print on Novaks website it mentions that the KV rating is based on
Quote:
"Indicates how fast the motor will turn for a given voltage given no internal resistance"
which is impossible!

So most likely Novak's true KV rating is closer to the others than it appears.
THe Novaks also have a lower power rating.

I've used the 10.5 motors in both a TC with Lipo and a 12th scale

without question, the Hacker wins.

Oh, that is '09 catalog in german, thanks for advise.
But why until now in english site is still described 10.5 has only 3080KV.
About that footnote of "no internal resistance" situation, i believe could the same case of motor rating of other brands, not just Novak, i hope somebody could comment about my opinion.

Right out of the box, both Hackers ran hot. I called their tech, he told me that it wasn't unusual for the motors to run a little hotter (160-180). I'll continue to experiment with them. I may try running them in my WGT this week.

if the losi xcelorin 10.5 is meant to be a hacker..
i have geared it to hell and back, put max punch on TC Spec (profile 8) and retarding timing to gain some torque back..
seems weaker than an LRP.. and the Novak looks like it screams along compared to the rest
