Problems with the speedy? I had a silver can and tamiya speedy in my TA04 that would get VERY hot and when the brake was applied, wouldnt go again for about 10 seconds. Swapped out the motor and speedy and it has gone fine ever since. Try another speedy if you have one and see if its has the same symptoms. Even try another motor(even a silver can) with your rooster speedy and see if it has the same trouble.
