Performance Tuning
Keep in mind, as you tune your GP-1 Ultra Mini Hydroplane for
top speed and handling that this boat IS SMALL AND FAST!
Because of its size it only needs very small adjustments to
change the way it performs.
STEERING DEFLECTION
Your GP-1 Ultra Mini Hydroplane has VERY aggressive steering.
It’s important to keep this in mind as you tune your boat. The
rudder only needs a small amount of defl ection to turn well.
Setting the rate knob to high (Clockwise) can upset the handling.
Ultimately, it needs to be tuned to your race course or liking.
SHARPENING
It’s best to sharpen the turn fi n to a razor-sharp edge. This will
eliminate drag and reduce lift. Remember as a rule of thumb,
if it touches the water, it needs to be sharp or have sharp
edges. GRIMRACER SAYS! Sharpen the outer edge of the
turn fi n toward the inside of the boat. This is a great way to
help control prop torque.
STRUT
The strut can be
tweaked
to change the ride of the boat but
only experienced modelers should attempt this. If you are going
to
tweak
the strut remove the prop shaft and prop. Loosen the
strut bolt. Move or adjust the strut, taking care not to lose the
alignment of the driveshaft to the motor coupler. If needed,
you might have to re-bend this area to regain alignment.

GP-1 ULTRA MINI HYDROPLANE RACING RULES
Boats must remain stock. Only hardware adjustments are
allowed. Sharpening and scuffi ng are legal, but changing
a prop is not. You are also allowed to paint or add decals if
you choose.
A heat race is 6 laps and typically consists of up to 6 boats
per heat. You can run as many heats per event as you like,
but 3 to 5 is typical.
To start a race, set a timer to 30 seconds. Launch the boats
and make one full clockwise lap. At the end of the lap, you
need to be on the right side of the start line and going full
speed. Being over the start line at the end of the 30 seconds
puts you in last place. Be careful not to “jump the start.”
Cutting inside a buoy AT ANY TIME will incur a 50 point
penalty per buoy.
Points structure goes like this.
1
st
place (per heat) 400 pts
2
nd

3
rd
place 225 pts
4
th

5

6

In fi ve rounds you have the potential to acquire up to 2,000 pts.
Good luck and good racing. Remember to
