You are going to get 100 responses and 100 different recommendations. Best thing to do is run what the fast guys are running at your local track so you have somebody to bounce ideas off, if you run into issues or need setup help. That being said, I have run just about everything, and this is the fastest combo to date:

Orion R10 ESC
Fantom 6900mah 100c Lipo
Fantom ION4 17.5 motor
12.5 High Torque rotor for Short course
12.5 Broad Power band rotor for Buggy

Default faster

Schuurspeed motor are the fastest motors out right know in 17.5!!
Better that any motor with a high torque rotor....
LRP has a new esc coming out this month the flow It will be very good and bulletproof!!

It's not even out yet and you are already calling it bulletproof?

I run a Viper VTX10 with a RevTech 17.5... I have also run the Reedy Sonic and Team Icon 17.5's. All preform well. No matter how fast the motor is, if your truck is not dialed in your not gonna go fast...

Reedy sonic comes with a 12.5 rotor out of the box and its fast and smoothe. Brushlesshobbies LT4 80amp or 120 amp esc. Same as the Reedy motor,fast and smoothe. Also it has a great price point. Brushlesshobbies.com

That really depends on layout and application. I have tried many, many setups with the Schuur Speed and while it's buttery smooth and very easy to drive consistently, it lacks low end torque that my RevTech has. In an SC at the track I primarily run at, if you don't have a torque rotor you have to swing wide to make jumps, costing precious tenths every lap. In a buggy I could give the nod to the Schuur Speed as the lighter weight would more than offset the torque loss. I just picked up a D3.5 Maxzilla to try out, but right now for SC I definitely say Revtech over Schuur Speed. And I really expect the new motor to outperform the Revtech .

Very curious about that D3.5 Maxzilla. How did it turn out?

Bryan, for your track I think the d3.5 is the top one right now. Might be biased but you saw my truck Friday night.

I also have the revtech but the d3.5 is a little bit faster, at least for me.

I would have to respectfully disagree with you on one point. The Schuur Speed motor does NOT lack low end torque. It comes with a 12.5mm Sintered Neodymium Rotor, which is a high quality rotor, and lends itself to more torque over other 12.5mm rotors. If you run a 13mm rotor you're going to have more torque, but 13mm rotors are currently not ROAR legal.

I am often able to find a setup and gearing that allows me to stay tight and make jumps that others who don't put the time in to figure out can't clear.

Like you said it really depends on the layout, conditions, and application/setup. If your truck/buggy can't carry corner speed or get the forward traction it needs from a motor putting out torque it may feel like a lack of torque. You need to gear and TIME the motor for the appropriate conditions. Every motor has a sweet spot for certain conditions. What you might think is a lack of torque could be wheel spin, or a loose slipper, or just geared high with too much timing.

The RevTech is fast, but I know of at least 2 guys that race at our local track switched to SchuurSpeed.

In regards to the D3.5, yes it's a fast motor, and it really shows in on-road racing, if you follow the on-road scene lot's of complaints about it, I believe it's also responsible for this http://www.roarracing.com/?p=1688 and this http://www.roarracing.com/?p=1703 but will have to keep an eye out to see which motors (if any) get pulled from the approval list.

There is a set of rules in which these SPEC motors have to be built to, and there isn't much that separates these motors, other than the design, weight, cooling, and quality of materials used to build them. Search for 17.5 to see, http://www.roarracing.com/downloads/..._Rule_Book.pdf

I would suggest trying out different brands and see what you like the best because really that is all that matters.

I thought that class was open? Pete told me that you were running a 13.5.
