This video shows a symptom. Potential causes: 1, improper ESC high point setup 2, a weak motor 3, a weak battery   It turns out the battery is not properly charged. A charger problem!

On a small scale RC boat like this one, the electronics are usually sealed in a closed box without cooling. After every 5-minutes runtime you should stop the boat and open it up. The electronics would need a short break so it can cool down a bit. Without some fresh air the electronics will die […]

When your boat has a good motor and enough battery power and it is still struggling, chance is that the propeller is failing (or is loose).  

When you do rock crawling you want to use a locker front and rear, which locks both wheels together so they spin at the same time with the same torque. This is necessary when crawling over rocks! With diff, the wheels won’t spin when encountering big rocks.   Another thing – high torque requires high […]

What is going to happen if you “mis plug” the connectors into the channel slots? Based on my experience, this will do no harm to most AM radio receivers. However, if you mis-plug into some modern 2.4g receiver, there is a chance for you to fail the binding circuitry. Just to be safe, the ESC […]

This photo shows a vintage integrated unit TPM6R. It is pretty large. I don’t like it. The functions cannot be used separately, it is all or nothing …    

The answer is yes, as long as you get the connector right. Airsoft Lipo tends to be smaller, therefore they can get overheat easily. Use it with extreme care – make sure it is not getting too hot.

Horizontally mounted dampers are not too effective. Horizontally mounted dampers that are too stiff are useless at all. This Interceptor has all the dampers replaced with the Kyosho Optima oil dampers. Much better handling now. The key take away is that with horizontal mounting the dampers must be reasonably “soft”.  

This is about RC boat safety switch bypass modification. As you see from the photo below, the two tiny metal contact points when submerged in water will conduct electricity allowing the power system to activate. The bad thing about this is that it makes it difficult to do testing off water. To solve the problem, […]
