If your Feilun FT010 is no longer zipping across the water like it used to, don’t write it off just yet. With a bit of maintenance – usually just a battery replacement – you can easily bring this little speedboat back to life.
Signs your FT010 needs attention
If you regularly run into issues such as:
- Sudden cut-offs during use
- Reduced run-time
- A noticeable drop in top speed
- The battery or motor feeling unusually hot
- An inability to charge fully
These problems usually point to an ageing LiPo battery, poor electrical connections, water ingress, or a damaged propeller. Any of these could be the root cause behind your FT010 losing its speed.
How to replace the battery
The FT010 uses a 14.8V (4S) LiPo battery pack. Replacing it is dead simple:
- Switch off all power and dry the outside of the hull thoroughly.
- Open the battery hatch.
- Carefully disconnect the old battery pack. Take note of the connector orientation and any hook-and-loop straps securing it.
- Inspect the battery compartment for dampness or corrosion. If necessary, clean the contacts with isopropyl alcohol and let all parts dry completely.
- Insert a fresh, fully charged battery. Secure it firmly to stop it shifting around at high speeds.
- Reconnect the battery, close the hatch firmly to maintain the seal, and double-check that it is locked in place.
- Follow your usual binding or powering-up routine, and test the boat in a safe area.
Beyond the battery: Other tweaks
If your FT010 still isn’t performing at its best after fitting a new battery, check the following:
- Clean the battery contacts – Every couple of months, wipe down the metal contacts on both the battery and the ESC with a cloth dabbed in alcohol. This ensures efficient power delivery.
- Inspect the drive shaft – The original “dog-bone” coupling design is known to have its flaws. If you notice vibration or wobbling at lower speeds, the drive shaft may need greasing or replacing.
- Check the propeller – A damaged or bent propeller will drag down your speed. Make sure the propeller is clean and free of nicks.
- Upgrade to a brushless motor – Mind you, this is a much bigger project. The conversion isn’t cheap, but the performance boost is massive. If you are handy with a soldering iron, it is definitely worth considering.
Summary
The Feilun FT010 is a brilliant little entry-level speedboat that punches well above its weight – provided it is running properly. If its performance isn’t what it used to be, don’t rush to scrap it. Fit a fresh battery pack and take it out for another spin. Want a bit more of a challenge? Give the brushless motor conversion a go.
