Even with this much timing and perfect gearing for my track the motor only hits about 120 deg...but I heard that the newer Sonic motors cannot go as far as the older ones.
There was a batch of motors that the timing has a limited adjustment just like what you are describing. We have since asked for that change to be undone.

If you need to get more timing you will have to take apart the sensor assembly and then you will have to file the legs on the sensor so that it can spin more. It's difficult to explain with out pictures, once you take it apart you might understand what I mean.

If you still have problem PM me and I will try to help.

Sean - Thanks...it's pretty obvious once I took mine apart.

For those that either don't have a "limited" motor, or who have modded theirs, where are you setting timing for 17.5 blinky sedan? At the middle of the screw, or on the far side...of even more??

Thanks, Denney

denney,

i'm centered on the screw at a 3.84 rollout w/fan (90x40 track) = 160*F (max).

my brain wants me to waste a bunch of time testing other scenarios, but after racing it this way with fairtrace and haynes at the classic and not feeling like i was giving up an ounce (not including my transmitter inputs), it seems illogical to think there's a whole lot left in the tank. just has a great balance of torque and pull set this way, and on a club level last week, it made everyone else's rip look straight amateur. in fact, i let someone wheel my rig at the end of the day, and on monday, they ordered themselves a new motor.

now, i simply have to figure out how to boost it with the castle esc ...

Anyone try the other rotors. I see on reedy's web site they list 3 rotors:

12.3x24 part number 954, stock replacement
12.3x25 part number 955
12.5x25 part number 956

Hi Guys...

Does anybody have any experience on a 17.5T Reedy with stock rotor with a blinky? Is 4.11 final drive a good way to start the motor at?

I'd start with the 3.84 mentioned in post #63. I run 3.7 but on a larger track (with Solaris tires).

Hi Guys..

My version of the reedy sonic is not at all labelled like yours?? Is this a new model that you have? I only purchased my motor 2 weeks ago...

Rick

I used a ratio of 4.00 on a blinky.... with timing to the end at the positive side... and the car was slow and only had about 110F after the run... It had 2 fans blowing on it tough... The track is not too big with only a 40 feet straight.

The car was not at all punchy... It lacked the want to get up and go effect.

Anybody has any idea how many degrees is a notch on the un labelled can?

40ft? (i'll remember this the next time i feel the need to complain about only having 90 ...)

regarding your settings, i would say that you went too conservatively on either, or both, the timing and the gearing. inch them up until you're temping 150*F or so after a run. my opinion is that the timing will make a bigger impact.

as a rule of thumb, i've never been happy with a program that comes off the track at 110*

With a whopping 40Ft of straight, I'd say that he is overgeard, no rpm means no heat sometimes.
The fact that he's lacking punch as well kind of points that out.

But I'm no Sedan guy so what do I know

I tried the motor for the last couple of race days and I like it. Very smooth power and the motor runs really cool.

I am running the following with good success:

Reedy Sonic 17.5
Full timing (to the screw)
FDR 3.92
Tekin 212 Blinky mode
Good fan behind motor

Temps are around 140 after 5 minutes

Good power; just as fast if not faster then the Revtech...
