West,
I think the sidewinder motor orientation is the best on NSR cars; inline is also not bad, just not as smooth as the sidewinder. We have had no luck with the anglewinder setup, the long can motors produce too much torque, even after replacing the chassis and motor-pod with their hardest options, the car still hops when being accelerated.
One think that we noticed on our wood track was that the air-ride hubs will increase the chance of a car to hop; replacing those hubs with regulars (solid center rib) would decrease hopping greatly.
Now, I would assume a problem with the tires if your car is tail happy but since you mentioned the air-ride hubs, those could be the problem – I have not had any luck with that type of hub. Also, assuming F22 are the best tires for your track, NSR super grips should be the best alternative – between NSR and MJK.
I hope this helps, keep us posted.
