I've had the same results with my 4.2 combo, exept I run it without the body (lighter) and without front wheels (doesnt flip over, less rolling resistance) and it also flys. I like the normal 4.2 king better than the pro, even tho I have a pro, because it seems to go faster and my perfection 3.5 motors endcap is exactly the same color (blue). Another thing I like about it is while using stock tires (all 4) and a 200mAH battery, when the battery started running down the wheels had enough dust on them and the motors was going only slightly slower it would do 3-4" drifts
overall it is great and anyone who doesn't have one has got to get one!!! I mean, a little over $4 for 2 motors
+S&H you cant get a 2.2 for that!
