I'm having problems (clutch, transmission, or shaft??) with my Redcat DPX 200. When I put it in gear and release the clutch, it will not move. Its like the clutch is not releasing. I can feel it go into gear. It does this in all forward gears and in reverse. At first I thought it may be the clutch but now I'm wondering if its not more serious.

Can anyone tell me what may be going on? Thanks!
