Howdy!

A few weeks back I picked up a second hand Traxxas Spartan and have been having a blast with it... until the XL540 locked up solid. So I did what anyone who likes speed does and upgraded. Dropped in the SeaKing 180 V3 and the 1600kv Leopard and after wiring it up took it to the water to find that it seemed awfully slow. Though understanding the 1600kv Leopard wasn't going to spin as fast as the 1800kv XL540, it seemed like something was hindering it from spinning at full RPM (<30mph on a pair of fully charged 8000mah 3S). Tried different 3S batteries, same issue. Tried a different TX/RX combo thinking it could have been the stock Traxxas units, no dice. Calibrated throttle input. Nope. I haven't found anything out about the SeaKing's programming that would limit the throttle input, so I am at a loss. Have a new CNC metal prop coming later this week and am hoping to be able to get the most out of the purchase!

Any help would be greatly appreciated.

Regards.
