Overall everything (except the Rebars) work well together. But I still had a big issue controlling my altitude while in the air. There is a section in the middle of the track that consist of a triple with the first jump being very steep. When hit at speed you can easily clear the triple. The problem is with the SC10 4x4 it would get the front a little high and then catch some air and do the parachute thing and no amount of brake would bring it down. The results were a tail landing or worst. I tried everything I could think of, slipper tightened, slipper loose, lower gearing, higher gearing, drag brake, tighten belt, loosen belt, adjusting braking power, etc. and nothing worked. On the bench when I gave it throttle and then brake I could feel the truck nose down, but on the track in the air it had no effect. I was really disappointed because everywhere else the truck ran great, but the altitude control was a deal breaker. To make things worst I had my Durango and Losi SCTE and they both responded to brake very well and easily leveled out in the air. The Losi in fact, was so strong I could almost do a front flip when I hit the brakes in the air. I was ready to give up when the Norcal guys showed up and they all had SC10 4x4's so I wanted to see if there trucks also had the same problem. Sure enough they also had altitude control issues when trying to clear the big triple, so it must be something to do with the design. One of them mentioned the truck almost feels like a 2wd truck in the air, and I got to thinking maybe because of the belt, decoupled slipper, etc. the handling was way different than any other truck regarding altitude adjustment. I noticed the trucks altitude was fine over the smaller jumps and I only had an issue with the big jump. With that in mind I started testing on the triple, normally I would power up to within a foot of the lip and then let off so the truck would fly level, with the sc10 4x4 this would cause the nose to rise, so I tried cutting throttle a little sooner and yes the truck now flew level. So it seems the SC10 4x4 is more sensitive to throttle (much like a 2wd) and once I figured this out I could nail the jump perfectly. The problem is this required cutting throttle sooner than I would on my other trucks which could be a disadvantage. It also required perfect timing and you had to have your approach just about dead on. With the other trucks I could get a little sloppy and use more throttle to clear the jump then use the brakes to control the altitude. With the AE if you messed up your approach you could not use extra throttle to help clear the triple (it would get nose high) and I had to slow down and double it.
