Description

AHTech Industries presents the Basic Quadcopter. A light training craft designed to train students in the handling of reaction-wheel-less multicopters. But its remarkable precise controls and high lifting capacity makes it also usable for all your Kerbin based construction projects.

Built in the VAB in KSP version 1.7.3.

Note:: An updated version of this craft is available as the Basig Quadcopter ng.

Design Notes

The collective blade pitch of the lifting rotors is set by small rotation servos between the engines and the blades. The control surface pitch of the four main surfaces is used for pitch and roll (or pitch and yaw when looking up) control. Two smaller auxiliary rotors give yaw (or roll when looking up) control.

Due to limitations of third party control module the Squad Automated Systems (SAS) will not generate yaw (or roll when looking up) control inputs. (See also: here .)

Usage notes

It is strongly recommended to to open and pin the control interface of one of the rotor engines and of the one of the collective pitch servos before flight. Lift control is usually done by keeping the RPM constant and adjusting the collective pitch of the rotors.

Switching SAS on and setting it to surface / radial-out will prompt SAS to keep the controlling probe core pointed up and thus keep the craft stable. Tilting the hinge connecting the probe core to the body of the craft in this configuration will induce a constant transverse motion. Alternatively the hinge can be set to its neutral position and small pitch or yaw commands can be used for fine control of the craft.

The collective pitch on the four lifting rotors is controlled with the up / down translation controls (I / K)
The rotor power (torque limit) is controlled with the forward / backward translation controls (H / N)
The tilt of the translation helper hinge is controlled with the left / right translation controls (J / L)


AHTech Industries recommends to perform a quick test of the controls and their aerodynamic effects before taking off. AHTech Industries is not liable for loss-of-control situations if standard procedure is not followed.
