• Why did my original rcsufer/RCLisa leak?
WHY DID MY RCLISA LEAK?: Most likely because you're not riding a RCSurfRider. If your Rcsurfboard is taking on water it's highly unlikely you purchased this from RCSurfRider.com. You got water inside the hull of your board because there wasn't a good seal around the drive shaft guide tube, outside and inside. Prop shaft guide tubes need to be sealed at both ends.

TO FIX LEAK: Try drilling a small hole inside the compartment, behind the receiver. Drill the hole to the size of your surfer's antenna straw, then use the antenna straw to suck the water out. When all water is removed and DRY, sand the tiny hole you made, then patch with foam, and then use epoxy or CA+glue. The prop shaft guide tubes need to be sealed at both ends. Remove old epoxy (at the prop end) and sand the area. Add CA then epoxy to seal both ends of the prop shaft guide tube. Use 5 min or 15 min epoxy and zap CA+glue.

•Batteries

Approximate run-times may vary depending on size of surf.
Q. How much run-time should I get out of the stock 1400 battery?
A. 8-10 minutes run-time

Q. How much run-time should I get with a 2400 NI-Cd battery?
A. 12-15 minutes run-time (more power)

Q. How much run-time should I get out of the 3300 NIMH battery?
A. 20-25 minutes run-time and killer power

Q. How long does it take to charge a battery on the stock AC wall charger?
A. 6 hours

Q. How long does it take to charge a battery on the upgraded AC/DC peak charger?
A. It depends! At 4.0 charging amps - 40 min. At 4.5 charging amps - 35 min. At 5.0 charging amps - 30 min.

Q. What's the difference between NI-Cd and NIMH batteries?
A. NIMH CELLS although similar in appearance to a sub "C" NI-Cd, has a different internal chemistry and requires different charging methods. These cells may be charged on a standard NI-Cd charger but some precautions must be taken.
These cells come partially charged so care must be taken when assembling and handling them. These cells must be stored in a semi discharged state to preserve the performance of the battery pack. Since the NIMH cells have no discharge memory, there is no need to deep discharge them by shorting out the cells. This will hurt the cells. We recommend using a discharger, which will discharge all cells down between heats. Remove pack when lights go out and recharge for the next heat. Do not dead short cells after charging or store with a resister across the pack. They do not need this and it will hurt the battery pack. It's necessary when storing the packs for more than a day or two they must be stored with some voltage in them (30% to 40% charge). Storing Nimh packs in a fully discharged state will deteriorate the performance over time. New cells cycle once before running and they may be used up to three cycles a day but require at least two to three hours between cycles.

•Charging information

The secret to charging NIMH cells is to keep them cool and nit let them overheat when charging. HEAT is the enemy of NIMH cells so they need to be charged on high quality chargers that let you adjust the peak detection point,(Negative Delta peak) like the Novack Millennium. Negative Delta Peak is the amount of time the charger keeps charging after the cell peaks. On most chargers this is set high for NICD's and must be REDUCED! Ni cd cells like to be over charged to reach full peak, NIMH do not! They heat up very quickly as they peak and putting them into this " Over charged" state will cause them to vent. To PREVENT this Sanyo recommends charging at the following parameters.
SINGLE CELL or 6/7 Cell Pack
To maximize the life of your cells charge at 3 amps with negative delta peak detection set at a level below 10 millivolts. (.005 to.009 volts) per cell.
If your charger has no way for lowering the peak detection setting, we recommend charging at 2 amps and keeping a close watch on the temperature. Remember these cells will get hot when they peak.
