ohhhh... mine did that pretty much out of the box!!! at the time i took it back to modelzone and the guy fixed it. that was my first rc so i did tinker with the servo.
get a spare 1 coz i think the gears are chewed!
for the saddle, you can reconvert it to saddle config but you will need to move the esc around.
Personally i would not use saddle pack since they seem a bit more expensive.
