TT01 stock plastic main drive shaft is too soft and can generate excessive noise under high speed. Replacement metal shaft can cut down the noise. However, the ball head (and/or the pin) on both ends can get loose and fall off. If this happens to the front then the front wheels will not spin properly. […]

Bushing is a type of bearing made up of a cylindrical piece of metal or plastic that is placed between two moving parts to reduce friction and wear. In an RC car, bushings are often used in place of more expensive ball bearings, particularly in entry-level or budget-friendly models. While bushings can be an effective […]

Running on a BL 280 class motor, this cart car is surprisingly fast. It runs just like a 1/12 pan car. Note that it does not have dampers. The arms are plastic which can flex to act as “suspension”. Toe in / toe out adjustments available front and rear: A small 280 brushless motor running […]

The answer is no. Very poor grip.

A typical brushed ESC would NOT need any special configuration in order to function. We recently came across a brushed ESC which requires adjustment of the transmitter TH position and still wouldn’t work. Its light keeps flashing, which feels like it can never detect and initialize the throttle position. Based on experience, this is entirely […]

A plane is subjected to many aerodynamic forces while flying through the air. It lifts up in the air due to the huge aerodynamic lift provided by its wings. In general, larger wing means more lift. However, that may also lead to more drag when wind goes in the wrong direction. . More info about […]

This type of glider focuses more on quick maneuvers. It has two coreless 720 motors running on 3.7V 300mah small battery. The connector is the standard small white connector:

A tachometer is a device for indicating the rotary speed of a rotating shaft. It can measure the working speed of a motor in revolutions per minute. The test button is for generating a laser beam to the reflective label on the rotating element. The reflective label must be secured on the wheel for proper […]

When the prop has the letter A on it, it spins to the left in order to push air to the back. Without the letter A, it is a B blade which needs to spin to the right to achieve the same. Most props support 0.8mm shaft. You need to know that for the coreless […]
