5. RUDDER The rudder can be tuned in a variety of ways The most important aspect is how sharp it is or you make it Using a flat file Sharpen the leading edge of the rudder finishing with 400 grit then 600 grit wet dry sandpaper You can also gain some performance if you remove the lift the rudder makes off the bottom of the blade You can either round or sharpen the bottom of the blade as either method works Another important aspect is the angle front to back of the rudder blade Tilting the rudder back and forth also changes the way the boat operates Tilting the rudder under the boat tightens the ride while tilting it back loosens it CG Adjusting the CG or center of gravity of the boat has a lot to do with how tight the boat rides as well as the how the boat flies as it enters and exits the water Moving the battery packs forward or rearward is the best way to adjust the CG SCUFFING Scuffing is a tuning trick boat racers use to increase the speed of their boat Scuffing involves dulling the area s of the boat that touch the water as the boat is running We like to use a red scratch pad like the ones you find in the paint section of your local home supply store Scuff the bottom of the boat to the point the shine is removed from the paint While this tuning trick is mostly geared towards the hard core boat racer sport runners can benefit from this as well IMPORTANT Scuffing will remove the attractive Shine from the bottom of your h

9. batteries Having said this As a rule of thumb we have found it best in very high current draw applications like an RC boat not to use more than 70 of the rated capacity of the battery pack per run We have also found that when in doubt and using the recommended propellers you can expect to use about 1000mAh give or take per minute of operation Using this you can better judge your runs knowing you re taking the very best care of your battery pack investment A GrimRacer Says It is best to test this by Gai am making a timed 2 minute run then charging the batteries back up and noting the amount of mAh the pack allowed back in Do this each and every time you make a prop change or any other significant change to your setup Then adjust your driving time so you don t go over the 0 usage mark Also keep in mind that car packs hard case could be used But if you get them wet they can store water causing the internal metal parts of the pack to corrode in turn causing short pack life We highly recommend the use a dedicated marine LiPo packs OPTIONAL PARTS L GPMQ4480 Hook and Loop If you purchase extra battery packs you are going to need to purchase extra hook and loop as well L AQUB9725 42X55 2 Bladed Prop This prop has great acceleration as well as top speed L AQUB9514 Grimracer Pro Radio Box Tape L AQUB9500 Grimracer Speed Grease You are going to need to re grease the drive cable after each day of running
