Alright, let me start by saying that my first upgrade to my hammer was switching from 6 to 7 cell batteries which made quite a difference on WOT. Id say a solid 3 mph gain.

I just ordered Miss Bud props 1/12 from HobbyFever.com
Let me start by saying these guys are awesome! I ordered 3 props and within 3 days i got my order. They only had 1 in stock, and wrote a note on the reciete they they will ship out as soon as they come in!
Over all analysis of the props are that the miss bud prop is much larger in dia compared to the stock hammer prop. I cannot test it yet because my ESC fried and a new one is on the way.

My mods that are in the Mail: Multiplex 600 motor. Proboat esc.
Doing some research, whith these mod, i should see approx a 25% increase WOT.

For the record: This is my first boat actually modding! Should be fun! Ill post back when i get the whole package on.
