Atlas/Uranus

[Hide]

Atlas/Uranus

This model is hovering by default and has a small electro magnet which can be used to deflect the main rotor to gain some forward boost. The protocol is mostly identical to the challenger protocol, only the last 5 bits differ, so one can use a challenger remote control to fly an atlas helicopter and vice versa (fire/pitch/light controls won’t work in this case).

See challenger.

Channel (2 Bits)

Unlike the challenger set, uranus helicopters are available with 3 different channels.

Channel Bits (Decimal)
A 00 (0)
B 01 (1)
C 10 (2)

Throttle (4 Bits)

See challenger.

Yaw trim (2 Bits)

See challenger.

Yaw control (3 Bits)

See challenger.

Pitch control (2 Bits)

Controls forward movement.

Function Bits (decimal)
hover 00 (0)
slow boost 01 (1)
fast boost 11 (3)
continuous boost 10 (2)

Separator (1 Bit)

Single 0-Bit.

Light (1 Bit)

When 1, a small blue LED in front of the helicopter becomes active.

Separator (1 Bit)

Single 0-Bit.

Checksum (2 Bits)

See challenger.

Stop bit (1 Bit)

Single 0-bit with same encoding as data bits.
