At IIC only ESC timing was limited. We were allowed to run any motor timing we needed to make the motor competitive.
Given the way the trend is going I think we will eventually see a fixed timing motor and rule. But until all the motors are timed the same it isn't something that should be enforced unless someone can figure out exactly what timing mark on each motor is the same.

I would think that no boost would be enough control to be fair for club racing.
All motors have different specs of physical timing.
No need to bring on unnecessary restrictions that bring about other inequities in pace.

) how do I convert that for lipo? Ideally I just want a single one that runs across like stick pack but will that be possible or will I need to stick to the saddle pack conif? Thanks.

Get the Speedzone 3.7v saddle pack. It will drop right in to the L3 and its an excellent battery. Placing a stick pack on one side and the electronics on the other works ok but you have to add way to much weight on the elctronics side to balance the car. I've used the Speedzone saddle pack in the OD12 and it fit perfectly with no modifications. Performance was better than with the battery hung on one side
If we could convince them to produce that pack with bullet connectors instead of Deans plugs it would be even better.

I thought it performed great. I came in 2nd in the D-main so while that isn't a ringing endorsement, driving wise I was very happy with handling of the car.
Yes, bullet connectors would be better, but I was really glad to have this kind of pack available.

Still wouldn't matter. How do you know 0 really is 0? Even if the manufacturer says it's 0 and the endbell is on the zero mark, that doesn't mean it really is 0. I know of no simple way to determine EXACTLY when the sensor trips at speed so there is no way to enforce this.

although the 'idea' of a stock class with fixed motor specs might seem nice, it would seem that timing is not entirely fixed by geometry, if one speedo ran a little more sensitve than another, it might 'sense' the rotor position earlier and get a little lead.
the way i understand brushless motors today, it makes the most sense to let every motor maker set its optimum fixed timing for its can, rotor, sensor set, and go. otherwise there will need to be a whole net set of motor spec's that demand the sensor trigger sensitivity be equal to a standard.

with the fixed ESCtiming class, what sort of motor timing and rollout did people end up with in the 17.5 1/12 class?

always the voice of reason, Dave.

Thanks for the advice.
I took out the motor restriction.
1/12 17.5 cirtix spec class is added, and made 17.5 open class.

It varied a lot depending on the motor. With my Duo 2 motor I ran it timed 1 tick from max geared at 54/72 with a 42mm tire. With the LRP I had the 2 hole timing geared at 62/72 I think it was. Might have been 64.

Anybody a LRP X12 13.5? Have you played around with the endbell timing? We're running out here with no boost (0 timing on the esc). Rollout is between 85-88mm between all drivers; just wanted a bit more infield grunt. I'm running a LRP SXX v.2 btw....
Thanks guys
