The Reedy S-Plus Competition Spec Brushless Motor was developed over several months of behind-the-scenes track testing. The heart of the S-Plus is a thin leg stator that allows shorter wire lengths, resulting in a massive reduction in resistance. This reduction in resistance, hovering just above the minimum allowed by R.O.A.R., means that the S-Plus is Reedy's most powerful spec motor ever!

The thin-leg stator offers another benefit -- weight reduction. By reducing the motor's weight, handling and chassis turning flexibility improves. Machined parts such as the can, timing cap, back plate, and sensor assembly have been placed on a diet. An entire section of the front plate has been removed to reduce weight with an added benefit of allowing the user to re-position it to lower CG depending on which type of car it is being installed in. A savings of nearly 30g has been achieved! Additionally, the motor's length has been reduced by more than 2mm, which aids left/right balance and moves mass towards the center of the chassis.

A redesigned high-strength, balanced rotor is more powerful that its predecessor. Because the rotor is interchangeable with those in 540-M3 spec motors, a wide range of tuning options are already available. Precision stainless steel ball bearings have been fitted to accommodate high RPM loads with exceptional efficiency and reliability.

Reedy S-Plus Competition Spec Brushless Motor (17.5T)
Just bought one of these and haven't run it yet. Put the motor on an analyzer before installing.

Here are the results---

The motor came set at 20. Timing is based on the can.
20-----2 Amps-----21,179 RPM-----2,749 KV
30-----2.6 Amps---22,439 RPM-----2,876 KV
40-----3.6 Amps---23,190 RPM-----3,011 KV
42-----4.2 Amps---23,488 RPM-----3,050 KV
44-----5.0 Amps---24,204 RPM-----3,184 KV
46-----5.9 Amps---25,184 RPM-----3,357 KV
50-----8.5 Amps---26,060 RPM-----3,569 KV

Your results might vary, but at least you'll get an idea.

Anyone thinking about buying one do it its crazy fast. I pulled it out of the box put 30/69 on it at stock 20 degrees timing. in my b6 with all mod drivetrain and slipper and stock bearings. it out performs the Fantom and the trinity monster certified plus and comes off at 104 degrees Fahrenheit. its was so good befor I left the track that night I ordered the 13.5 for wheeler

Motor is fast and light. Using in my B6.1d on indoor clay. I am running it geared for 38deg timing but turned the timing down to 26deg because I don't need the extra speed and so it runs cool. Had to add weights to my car because of the weight difference from the old motor I set it up with which lowered the CG. Have run a few full practice days and a few races without issue.

Reedy S-Plus Competition Spec Brushless Motor (17.5T)
This new reedy 17.5 is a big improvement from the last
The positives, Reduced weight combined with professional wound stator makes the new reedy a race winning motor.
The Negatives, more sensitive to gearing and hi timing over the old reedy.
Tones of engine breaking due to hi strength magnets no need for Esc drag brakes.
Best gearing for me is 6.5:1 FDR or 72/27 for Losi imo I run is 32 degrees of timing I find it the most reliable for the power.

I've used this motor for 1 day of practice. Timing set at recommended 38. It's fast. You are going to need to drop down the pinion because this motor likes the revs.

Don't waste your money I used this motor less than 10 hours and it smoked while in practice. I thought my car was on FIRE. never ran more than 6 minutes temp was always around 130. Don't buy...... ran on stock timing... I'm pissed I wasted my money.... if u buy u have been warned. . . .
