Gyro Mounting -

This model uses three gyro's, one for rudder, one for elevator and onefor aileron. Each has to be mounted in its correct orientation. I am using the well tried and tested Futaba GY401 gyro's with rudder in heading hold mode and the others in rate mode. I fabricated a mount for the aileron gyro and mounted the others directly -

Reciever is a 6 channel 2.4Ghz spread spectrum to give the best range and reliablilty, the diversity receiver was mounted on the side frame. The receiver is placed to give the shortest possible lengths for wiring -

Receiver power is from a 2S 7.2v LiPo battery and therefore a regulator is required, I used a new Fromeco Sahara regulator rated at 10A which is enough to drive all the on board electronics.

This model requires a good deal of electronics to control the motion of the rotors, this is done using a Helitronix mixer manufactured by RC2Rotors - http://www.rc2rotors.co.uk/ This takes the output from the receiver and applies the correct movement to each head, see the flight section for more details -

The motor speed controller was mounted as close to the motor as possible, this is a Castle Creations Pheonix 85HV unit -

With everything in place wiring was done as neatly as possible, I used a power bus to seperate out power from the receiver and mixer. I have a switch feeding power initally to the regulator but then a seperate connection using deans once the initial power is applied -
Flight power comes from a very large and powerful 10S 37V 5000Mah LiPo battery rated at 35C. The battery is placed strategically to balance out the weight of the motor at the rear of the chassis -
Throughout fitment of the electronics I was switching power on and checkig to see if everything was working as it should, with this phase complete it was time to move on to flight preparation and setup.
