C.G. (Center of Gravity) explanation for new model boaters. The center of gravity is where the boat balances.

Center of Gravity is very important in having a great running model boat.
Unlike real boats, model boats spend most of their time flying across the water.

The rougher the water or the more power you have, the further forward the center of gravity needs to be. 
You want to keep the nose down in rougher water for better stability.
Have a look at the center of gravity suggestions in the instructions for your hull and remember 
you can always move the Center of Gravity forward with a weighted pool noodle
 but don't build too far forward because you can always add a weighted pool noodle to compensate for water conditions.
Its better to build your boat with a Center of Gravity slightly closer to the transom because with an ounce or two 
of weighted pool noodle you can achieve the perfect Center of Gravity for the water conditions.

If you are a sport boater, the best way to build your boat is with a "close to the transom" Center of Gravity
The reason is that in calm water with no pool noodle, a hull will run really loose which equals speed.
If the water conditions become rough, you add the pool noodle that is best for the water conditions.

Each one of my personal boats have three pool noodles, each with different calibrations (amounts of lead) 
I use none for glass calm water, 1 for slightly rough,1heavier for rough and 1 heavier still for super rough conditions.

Pool noodles should be marked and calibrated to move your Center of Gravity forward.

Measure and mark the starting Center of Gravity for calm water.
Measure from the transom forward. Mark both sides of the hull.

  1. Mount all the hardware to the transom of the boat. 

  2. Slide flex cable through the drive

  3. Attach prop (and all hardware)

  4. Place radio box in hull

  5. Put everything inside the radio box including batteries and lid

  6. Bolt engine to mount

  7. Attach header and tune pipe to engine

  8. Place engine inside the hull

Pick the boat up with your index fingers on the marks you made and the boat should balance.
If it does not balance, move the engine or radio box forward or backwards till it balances.

Mark the locations and mount engine and radio box
Finish assembling your boat ( water lines, fuel lines etc)

Build additional pool noodles for rougher water conditions, 
Remark sides of hull approx 1/2 inch to 2 inches forward of previous marks depending on length of hull
S
hort hulls will need less distance to increase the Center of Gravity for your first pool noodle

To determine how much lead to put in a pool noodle;
 tape a cup to the bow of the boat,
 add lead to cup until the boat balances using new marks

Use wheel weight lead hammered straight

 

Shave pool noodle to a point

 

Make a cut half way

 

Wrap clear hockey tape ( works the best) around the bottom half of the pool noodle and the lead (tape well to eliminate loosening of lead)

 

cover the noodle and lead with radio box tape

 

Using your radio box tape, make a wrap around the pool noodle, then with a permanent marker, write the center of gravity in inches on the tape,
 wrap again to cover marker and that pool noodle is finished

 

Repeat steps to achieve additional noodles using Center of Gravity marks on hull moved further forward
 and increased lead amount to balance boat for rougher water conditions

 

Cut a V in the end of the pool noodle so it anchors itself on the zip tie that holds your IV Gas tank in place.

 

Having pre-made noodles can change the attitude of your boat to compensate for changing water conditions in seconds

 

This applies for catamarans as well except you need two of each (one per side)
