With the Tekin, you can at least narrow the RPM start and finish to increase punch a bit.

Increasing the motor timing definitely helps with punch, but have to find the happy medium of ESC timing as well so I don't cook it.
Highest I've had the motor timing is the third notch but I'll try to go up to the 4th with a bit less on the ESC and see how it goes.

Ive tried everything on the RS and found where I want the motor. Smooth = not punchy. If you want the rip I suggest a different motor. But by all means the Sonic is just as competitive as anything else on the market

Modified motors seem to have their stators and rotors in diffrent physcal positions from their stock counterparts. Using these reedy sonic rotors as a clue it appears that the mod rotors have their magnets closer to the front of the motor...

Sonic Stock Rotor 12.5 x 25.0 (Part #956)


vs.

Sonic Modified Rotor 12.5 x 25.0 (Part #958)


... because that little brass collar is spacing the rotor away from the endbell/timing assembly. What I don't get is why?

Both rotors require the little brass spacer, somebody probably dropped the spacer on the stock rotor when doing the photos.

Just bought one of these in 21.5 for f1 racing. I am replacing a 21.5 Novak that I was borrowing. How will this motor compare to the Novak? Hoping for a little more rpm since the f1 doesn't need a ton or torque. Please be honest in your answers.

Any tips are always appreciated. Thanks.

Boost or blinky?

You are correct. My stock motor has the brass spacer.

Blinky. We can not use electronic boost but as much motor timing as we want. Currently running a Novak edge esc.

The Sonic is very good for F1

Check over at the UF1 page for setups.

F1 is alive and well in So. Cal!

I would start the motor timing at around 38-40, depending on gearing and size on track.

What are your speed control settings? Too much initial punch can cause a low speed hesitation.

Ran this motor for the first time yesterday. It has more punch and more top end over the Novak I was using. Ran my fastest lap by 0.3 last night. Great motor.

It does seem to run 20 degrees hotter than the Novak. I noticed my Novak motors cool down after they have been run for a while. Will the reedy cool down as it breaks in? It didn't overheat but it got up around 150 with one spot temping at 160. The Novak ran around 130 with a hot spot of 145.

Is there a particular technique for removing the bearing from the sensor unit?

I can make it move a bit, but as the access hole on the opposite side is very small I can't get anything into it to push the bearing out.

HEY GUYS

Does anybody know how many degrees of timing does the neutral mark on the reedy sonic have? I have the version without any numerical markings. Also how much timing is each marking?
