Default My 2 cents...

Most of my dragster experience, ok, all of my dragster experience is in a FED. However, a hardtail RED may react in a similar fasion. My FED would "chirp" as you decribed if the balance of ballast, tire pressure and power was off; even a little. Personally I wouldn't add ballast for a 3" wheelstand. Try a 10 footer......anyway, if I tried to get my FED to "deadhook" it would chirp. Adding a little front ballast or a little more tire pressure would usually cure it. What happens is the front pops up too quickly for the momentum to carry it, so it drops hard and causes the chassis to ocillate or bounce causing the chirp and a loss of ET as well. If you get the correct balance, the front will rise and fall smoothly. In my FED, any attempt to keep the front end on the ground (too much ballast) would cause it to spin but not chirp.
