Heng Long Tanks Frequently Asked Questions

How long should I charge the battery for?

Before you can run your Heng Long Tank, you need to first fully charge the 7.2V rechargeable battery with the basic charger. Both are included with the tank. The charger is 400mA. Therefore for a 1700mAh battery, charge it for 4 hours 15 minutes (1700/400) for a full charge. For a 2000mAh, charge it for 5 hours.

With the Ni-Cd battery, it is best to run it down until it is exhausted before recharging again. Use a discharger if you have one to discharge the battery before recharging. This is to avoid the 'memory effect' where left over charge accumulates to degrade the battery's ability to hold its charge and therefore reduce its lifespan. This does not apply to the Ni-Mh battery, you can top up the charge whenever you like with minimal affect on battery life.

My smoke generator is not working properly. What should I do?

The smoke unit should already be primed at the factory so you should see smoke coming out of the exhaust after a while once the heating filament has got working. If no smoke comes out after a while, add a few drops of smoke oil into each nozzle. Wait for the heating element to work. You should be able to see the smoke pumping away after a while. You can switch off the smoke generating unit if you wish. The switch is underneath the tank.

It is important that you don't keep adding smoke oil into the smoke unit if it doesn't work quickly enough and end up flooding the heating chamber. Once it is flooded, it would take the small heating element a long time to dry it out sufficiently to create smoke again.
