Moved this to the proper place. Hopefully someone will be able to help you out.

Found the manual/parts explosions for it here, so when someone helps, they can check it out:

The only thing that comes to mind from me is that maybe your throttle/brake linkage is setup really off the mark causing the brakes to bind when you apply throttle. Did you buy this thing new or used? Did it work correctly at one point in time them this started happening? If so, did you work on anything on it then now it doesn't work?

Take the body off and post up a decent top chassis photo for us to look at if you can.

Kyosho has a very good owner's manual, at least my ST-RR does. It describes exactly how to put it together properly.

In the 4th pic down, you can clearly see the front brake pads are clamped down on the brake disc. Adjust the linkage to remedy this. If that is not the answer, loosen the 2 bolts going thru the brake pads until it frees up. Use 1/4 turns out on each bolt. Then check for proper operation. LMK

When you give it gas, does the circled rod slide through the slide in the circle or does the slide and arm move forward with the rod?

The rod should slide in the slide. If the arm moves a little bit, then that should be fine as long as it's loose and not applying pressure to the brake when your giving it some throttle.

Or, your front diff could be fried on you or the dog bones (axles) could have worn cuts in the cups causing them to bind up when force is applied. In this case, the force is forward accelleration.

You can see what I mean here from my savage:

Those gouges worn in the cup cause the ears on the axle to hang and bind. I really should replace them before they hang and snap my axle.

omg thank you I'm gonna try to see if the rod slide or not. But I don't understand what you mean when you are talking about the dog bone I k ow what the dog bone is but I don't know wats wrong with it. Thanks you are being extremely helpful to me.

hi umm I'm kinda a noob at rc but where is the brake pad linkage.

Sorry, the circled pic is one part of the linkage. Turn the black knobs out to release the brakes.
