Today was the 1st time I had a REAL chance to test the drift gyro that I placed on my 3.3 4Tec. WOW!!! What a huge difference it made in controlling this little beastie. The sensitivity was set to nearly minimum. For the 1st time I can go full throttle and control it. No more swapping ends because of poor traction. I can also go into a turn much faster and get on it coming out without swapping ends. If you have even considered one, do it. I had tried all of the "miracle" tire combos and nothing. BUT the gyro is the real deal!
