Best 17.5 brushless motor for off road?
I'm in the market for a new 17.5 brushless motor and want to know what some of you people have come up with as to a good 17.5 motor for off road. Im currently running the speed passion 17.5 and it just feels soft. My Final drive is at about 6.9 and I just want something more. I want to know if anyone has ran the new LRP, Orion, or Trinity motor's and what they think or how they feel to them. Thanks for any help

Seems like Novak motors is what almost everyone runs.

What car are you running and what is it geared? I have used Speed passion, Losi, and Novak and like the losi and Novak the best. The speed passion felt a little laggy to me but it could have been geared wrong.

XXX-t cr and it has a 29 pinion 82 spur with an internal of 2.43. The actual final drive is 6.81 I also want to hear from anyone whose used a novak compared to a LRP, Orion, or Trinity. Thank you

I have the new Trinity 17.5 in my T4 and it's a torque monster. I run 31/76 for a final drive ratio of 5.78. It accelerates very good. 31 is the biggest pinion I can get on there.... for now. After a five minute main it's just barely warm, so you could go bigger on the pinion.

Well I am running a novak 17.5 and my fdr is 5.0. Running a 72 spur, 36 pinion....I am going to put a 38 pinion in it soon as my motor/esc only gets to about 50c. That will give me a fdr of 4.7! You have to run brushless near the limit to get the best out of it. In comparison to the lrp, speed passion etc, I would have to say it is fairly close. No wonder you are getting sluggish performance running @ 6.9 fdr. How hot is your esc/motor getting?

dennyboy424 11-17-2008 07:50 PM

LOL Im geared crazier then anyone at my track. They recommend 7.5. Ill push it to the limit and run it at 6 or 5.5 and see how it goes! ;)

dennis, ur gunna have to run a smaller spur, ur gunna run outa room!

dennyboy424 11-17-2008 07:55 PM

Im going to pick up a 78 or 80 tooth spur and get the biggest pinion I can in there! :lol:

not home 11-17-2008 07:57 PM

well call me COPY lol dont you think that going a lower fdr will have a disadvantage with the tight track we run at?

dennyboy424 11-17-2008 08:04 PM

I would like to hear more from people with the Trinity, new LRP, or Orion vortex. Maybe even the Tekin sensored motor which looks pretty good as well. :nod:

What up? 11-17-2008 08:42 PM

Murfdogg motors
I run Murfdogg motors which is a Trinity based brushless they are very torquey which is really good in offroad. I used to run Novaks and they are good as well off the shelf.:nod:

I have tested speed passions and they are alittle soft on the bottom end.

The Orion's are looking really good as well with there phase 3 brushless. Not out yet though.

anyone run the new hacker or trinity? even the tekin looks nice
im still undecided as i have herd of a few people buying new 17.5's coz theres others were no good, i have only herd bad news from the speed passion :s

dennyboy424 11-17-2008 09:11 PM

Lol great I could tell it was a dog when everyone with a novak is ahead. :( Well the new trinity pulse is comin out and the new orion. Im gonna gear this thing higher and just hope it blows. :lol:

lookiezx-5 11-17-2008 09:18 PM

Well i can guarantee that everyone that is fast has a lower fdr. Do you check the temps after each run? You can run a novak upto say 175 before it will go bang. I know some ppl who have a fdr of around 4.0 in a b4!
