This video shows some comparison between different configurations. 1, What we have here is a red plastic boat with a brushed 380 motor and a 2s pack. The green fiber boat is 3s powered 540 brushless. 2, Now the green fiber boat is running against a smaller boat with a brushed 21 T 540 class […]

This example shows a RC catamaran.   When for whatever reason the hull is broken, you may try to fix it by using a combination of glue. First you can use the so called A B glue, which requires that you mix two different glue together and have them applied quickly on the cracks. They […]

Modern entry level RC sailplanes use a very simple architecture – there are no moving parts other than the two propellers. For starters there are less moving parts and therefore less complexity. Not bad for beginners. But definitely not the right kind for experts. The battery is 3.7V, either 300mah or 550mah. The plug is […]

There is one small but long screw that holds the propeller. Remove it, then ply out the pinion and put […]

When a RC plane crashes, chance is that the plane head suffers the most. For entry level RC plane you can use glue to attach it back, but for it to be properly secured you should use some tooth picks as the bones. Glue alone is never strong enough. And make sure you let the […]
