RADIO CONTROLLED KOAXIAL HELICOPTER RTF - Tamiya

Equilibrating the modelThe helicopter must be correctly balanced. If there is anincorrect location of the centre of gravity, you lose the controlover the model!The location of the centre of gravity of the modelis preset. Corrections are only necessary if you arenot satisfied with the flight characteristics.The centre of gravity of the helicopter-model should lie exactlyin the rotation point of the rotor axis.Shift the airplane battery in order to determine the optimallocation of the centre of gravity.• Hang the helicopter on the upper rotor head, in theextension of the axis of rotation. The helicopter may not tipforwards or backwards, no matter in which position theprincipal rotor blades are located.• If the nose drops, then the model is top-heavy. Shift theairplane battery slightly backwards.• If the tail sinks, shift the airplane battery forward in order toadjust the centre of gravity.Secure the airplane battery when you have determined theoptimal location of the centre of gravity.Lateral equilibration• Support the helicopter at the end of the tail beam and fronton the longitudinal axis as far as possible. To do this, removethe cabin hood. The helicopter may not tip to one side, nomatter in which position the principal rotor blades arelocated.GBFastening the rotor bladesThe rotor blades must be able to align themselves 180° to eachother solely by the centrifugal force.• Therefore check the seating of the retaining screws (a) of therotor blades:The screws may only be tightened firmly enough that therotor blades still fold downwards when you tip the helicopterto the side.(b)(a)CARSON Helikopter EC-135 Rescue 50 050 703117
