There is no one brand that works best but the LRP and Tekin were used in most of the testing.





Not the same. A lot of motors start as the same thing but are altered and modified to suit a particular vendor. So they may share the same DNA but ultimately are different motors.

Def a different motor. Rotors are different and so is the bearing size closest to pinion gear.

Really enjoying my Sonic 17.5. So far running 0-boost haven't had time to run my boosted TC but i am very pleased. The Power Band is definitely a lot smoother and the low end is a lot easier to use while staying smooth. Compared to an LRP X-12 the Reedy has softer brakes but still sufficient I just had to turn the brake EPA up a bit on my transmitter versus the setting I was running with the LRP. No radar or timed heats to verify but on feel and observation I don't think there is any difference in top end between the two and so far running on 0-boost 0-timing motor is coming off ~155 F after 20-30 minutes of running.

Very glad the Reedy brand is back in the motor game and this looks to be a winner. I love the decision to go with the black can too.

I'm glad you said the temps are low. I ordered a reedy 6.5 a week ago. It takes a while to get to Hawaii. It's been so anoying with the 7.5 x12 in my dex410. My sxx tc is set with no boost, geared low, and only run it late afternoons when its cool outside, and still in less than 8 min the motor is above 180 degrees. It makes my lipos really hot too. The sxx also gets pretty hot too. I ordered the rs pro to replace the lrp. We'll see how it goes.

Does anyone know the stock rotor dimensions on the 17.5T? Looking to buy optional rotors to go with my 17.5 but not sure what's the original dimensions.

Thanks.

12.5 mm high torque I think x 25mm

I see. Bcos there seems to be quite a number of rotors available but it is not stated which of those are standard items in the stock and mo motors.

As far as I can see there are:

12.3 x 24.2 (7.25)
12.3 x 25 (7.25)
12.5 x 25 (7.25)
12.2 x 25 (5.0)
12.5 x 25 (5.0)

Also, what does the 7.25 and 5.0 refer to? You mentioned that the stock rotor in a stock class motor may be a 12.5 x 25. However there is a 5.0 and a 7.25 version of that rotor. So which is the exact one found in an off-the-shelf Sonic?

Thanks.

Ran my 17.5 Sonic in "race conditions" yesterday and wow what a great motor. The smoothness on and off throttle is amazing as there is no jittery/jolty/disconnect (read as: no "spool and launch" action) at any point in the powerband making for very smooth speed transitions.

Ran 4.0 fdr +timing on the 4th notch and it was coming off the track in the ~150F range... There was plenty of smooth low end and as far as I could tell plenty of top end as well alongside the other cars on the track.

THe bottom two are mod rotors and the 7.25 and 5.0 represent magnet thickness

No the 7.25 and 5.0 is the diameter of the shaft where the magnet mounts.
Spec rules call for the mounting shaft to be no smaller than 7.25mm this limits how much magnet strength the motor can have.

Is there any chance that Reedy will be able to supply the Stator's separately, like Novak, so we can rebuld motors that have been overheated?

Thanks

This is a possibility. We have had only limited requests for this so far but if there is enough interest we will offer them.

sensor end is 3x7x3 and shaft end is .1875 x .5000x .1960

We are gong to post bearing and other replacement part info on our website this week.
