Bradz, There is alot of science that goes into how a prop works and what to change to increase speed/acceleration (Hole Shot)/lift. There are several parameters that can be changed to affect the boat performance. Pitch, Prop diameter, cup and the number of blades can all be changed to modify the way that the motor's power is translated into the boat's propulsion. Even the material that the prop is made of can make a difference due to blade flex.

Check out this thread for a recent discussion on prop specs: boat-tuning

i looked in there and saw pitch tabs as well but the thundercat don't have them does any one have a thundercat if so are they useing a 2 or 3 fin prop?

Bratz, buy some carbon props by Graupner and find out what suits your boat best. If it has enough runtime and speed buy a metal prop and have it balanced.
