Default 17.5 high torque rotor

Anyone use high torque rotors in 17.5 blinky 2wd buggy class? If so, what's your experience and which motor?

I have been running the reedy sonic 17.5. It comes with the 12.5 rotor and is a very very good motor! I like the 12.5 rotor over the 12.3 for grunt out of the corners and having the torque to get over the bigger jumps. This is for buggy.

I have a D3 Express 17.5 with a 12.5 rotor and it rips.The Shuur Speed 17.5, I run in everything but my buggy, comes with a heavy rotor. It espcially makes an SC feel faster. Its not as neccessary in a buggy but some like it. I think all 17.5s should come with one and the lighter rpm rotors should be an option.

I ran an H/T rotor in my Tekin, I've since switched to a Orion and I don't know the rotor spec in it. When I did the Tekin HT rotor, I liked the extra acceleration I got off the turn as well as the stronger drag brake effect. I had been used to modified which is geared so much lower that switching to stock was a big change.

How are you guys gearing and working with timing with HT vs std rotors?

I like the 12.5 rotor in 17.5 buggy. You can gear up and still have top end and it has the low end power to clear some of the jumps that I normally can not clear if I'm running the 12.3 rotor. I have found it better in all situations for me.

I think I'll be buying the 17.5 d3.5 that has the 12.5 HT rotor.

my viper vst 17.5 came with the 12.5mm rotor, and they offer a 12.8 as well. I am about 2 teeth taller then recommended for my 22sct!

With my Orion I'm geared 35T/70T in a losi. I could go taller if the gear would fit in the car. Motor comes off barely warm. Maybe I'll tweak the timing...

Just FYI: That motor is no longer ROAR approved because it was found to have wire that was larger than allowed by the rules.

LOTS more (100+ pages) here: http://www.rctech.net/forum/chat-lou...-5-17-5-a.html

But this sums it up nicely: http://www.rctech.net/forum/11734919-post1558.html

Then why not get one of the Novak ULR (Ultra Low Resistance) stators or motors and a Novak 12.5MM rotor? You can get that combo through the Build-A-Ballistic program.

Many clubs and non-ROAR affiliated tracks use ROAR rules for motors, so that is why I mentioned it.

Never heard of it. Link?

But I already made the purchase.

Awesome motor ! I believe I am geared at 70/35 , end bell timing cranked and still only 95 degrees after a 6 minute run .


ta_man , many tracks are still allowing the D3.5 motors regardless of Roar`s "new findings" .
