Default 17.5

Perhaps this has been previously covered, however I ran 17.5 in TC on asphelt today, with stock settings, as comes in the speedie initailly and had serious cogging issues using a Hacker motor.

My rollout was 56mm and once the car was moving the thing was quick, but off the starting line I was run down by the complete grid, before the car would start to work.

Not sure if this is a common problem with this combination. The speedie is a PRO GT version 2.

Thank you,

regards,

Calvin.

I had the same problem with a losi motor(which is believed to be the same a a hacker). It ran fine with a SP motor, so it seems to be the motor not speedo. I have since moved the rotor closer to the sensors and it now seems ok.

Pardon my ignorance, but how do you move the rotor closer to the sensors. Is this done by adding/subtracting shims???

Thank you,

Usually thats what you do. But the Hacker/losi rotors don't use them so I put the rotor in my lathe and turned down the shoulder it bit then added shims on the other end. Before I did this there was around a 1.5mm gap between the sensors and rotor. It was ok like that with my LRP but not the GT2.0. I'll be back racing at windsor soon and can help you out if you want.

Just got myself a v2 5.5t motor to sit next to my 4.5, and as i have compared sp motors with other it seems that the sp motors produce more rpm`s than the others? (looking at numbers, have not tried them on the track just yet)

and gearing, how much can i gear the 5.5 before it gets too high? (large outdoor track, with lipo)

cant wait to try them out on the track!

Sp 5.5 at default timing on a large track i would start at around a 7.8 and watch the temps.

Does the 2.0 have "Turbo" timing?

I dont believe it has turbo timing or at least i dont see it in the menu...but it keeps up with any other ESC out there. I have personally raced with exact setups as other racers with the exception being the ESC ... and it keeps up.

It might also be an idea to throw some different software at it and see if that helps. I have tried quite a few versions and there is a big difference in the "feel" and a smaller difference in performance between all of them. If the software fixes the problem then you won't need to mod the next motor you buy.

As a note I suggest trying either the SP motor or the duo. They seem to be getting results.

At this last weekends nationals.
A buddy drove my 17.5 TOP Racing Scythe with a LPF 2.0 and SP 17.5 and he was flying. he qualified 4th in the a-mains and finished in 3rd.
We kept gearing up and found the 58mm roll out to be the sweet spot for us.
Updated the software to the suggest version Shawn gave 205C

razzor or Troy,

Where can I get a copy of the 205C software? Thinking about, it is most probably a better idea to get another motor. I will see if I can get a SP 17.5.

Thank you.

Calvin.
