Atlas/Uranus


=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).

==Header==
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.
