i just took one of my Dslot cars apart and was wondering if the handling of the car would improve if i move the motor nearer to the rear axle?

i´ve built some chassis with nearly the same configurations and by now i tend to say that the handling would improve with the motor in the backmost position.

what do you think?

Overall, I would say yes Peter, BUT there are many factors to consider, Size of motor, smaller motor further back, a big motor like Artin, maybe not so much, because the pendulum effect will most likely be too great for the tires to overcome. Oh, and then there's the tires! Skinny tires will need some weight over them, but again it could get to be too much pretty fast; Wider tires with more contact could probably easily stand the additional weight. What about wheelbase? Long wheelbase car with extreme rearward mount might not be good either???

Hard to say with the D-slot, how much fore/aft adjustability do you have?

i think i can get the motor back 2 or 3mm, cutting the motor axle and cutting the pinion.
this would apply for the 917 and the 962 chassis (SS and L).
sheet styrene chassis with the original axle/tires, motor, pinion, crown, brass bearings made from brass tube 3/2.4mm.
i don´t want to cut the motor axle and the pinion if it´s worth nothing.

It sounds ok in theory Peter,but, as Mas says, there are so many factors to take into consideration that the only way to see if it works is to do it. Maybe after you've tried all the other 27 adjustments on the Dslot first!

left - this is the goal right - original DSlot

i want to get THIS!
this is not possible with the DSlot chassis and the DSlot body mounting. Also the motor is too high, cannot be changed. So i will build a chassis that will work for me.

just wanted opinions and experiences about the motor placement as i´m lacking there ...

Here is a Jouef chassis in a Kyosho 917
Quiet nice, except for the wheels but...
