  • The back end comes around ...

    Coming out of turns the back end wants to keep coming around, leading to spin-outs. Remedies?
    Some background: Scaley Javelin body atop a Shapeways 3D frame, Slot-It SW pod, Piranha motor, 15mm x 8mm wheels (as per the rules and all that will fit, anyways). No magnet. Got some weight up towards the nose, some weight in the middle.
    Thanks.

        Try loosening the body screws and/or the motor pod screws. You want the body to create some roll in the turns so the outside tire can hook up more rather than slide. You can also try raising the weight and put it on the underside of the interior tray which will also help it to roll more in the corners. If the weight is too low, then the rear end will tend to slide. It's a fine line between a rear end that slides and one that rolls out of the slot.

        Of course, it's really important to have tires that really hook up in the rear.

            Are you accelerating too much before your car is completely out of the turn? Before giving it the gas make sure you’re rear end is straight and not still on the turn.

                  You probably won't get better tyres than that other than foams with goop!

                    There is really not enough here to make recommendations other than the practices noted by the linked article and some other small items.

                    One thing that can make a difference on what needs to be addressed. Is this problem occurring when you are slowing to enter a turn? Or is it happening when you get on the throttle to exit the turn?

                    You have to pay close attention to this at times, because you will start to lose the car at the start (entry) and then just make it worse by adding throttle....But the tuning strategies for fixing either of those two scenarios is going to be very different.

                      About Kevan's advice... I throw people out if there is a hint of goop, glue, mucilage or anything else like it. Every one I know has the same policy, so ask ahead if the owner will allow the nasty crap in his building.
