I actually don't think it is an disadvantage to have a 3-gear transmission.
I "mirrored" the tranny just to be able to run sensored motors.
Compared to many other mid-conversion I have seen, my car have both the motor and battery pack about a full cm closer to the rear axle. The chassis is on the other hand 1 cm longer in between the suspension mounts compared to a stock rb5. But with the flipped rear wishbones and shimming of the rear hubs the total wheel base is now just about 2~3mm longer than stock. The wheight distrubution is almoast the same as the stock rb5 so the only "change" really is the change to a lower yaw and pitch-Inertia.
And there is also no extra wheigts added to this car whatsoever.
Since last uppdate two more indoor races hav been attended.
Both ended upp at 2:nd place.
Wich happens to be my best 2wd result ever.
