Mine too was doing this, But strangely enough mine started acting up when I stiffend the springs. It would wheelie very hard, and it seems like when I'd briefly let off the throttle to get the front end down it would momentarily lockup. I went back to softer springs and behold, it stopped doing this. Very weird indeed. I'm sure this is only a sympton of the real problem, but sure did stop. I too run a spektrum system.
