Operating Instructions - SOLO PRO 290 RTF 2.4 GHz No. NE2516
Check the correct position of the swashplate before the first flight. The swashplate must be exactly horizontal when viewed from the side
and front of the model. Position the helicopter on a totally flat surface. Now move the throttle stick to the lowest throttle position, and switch
the transmitter on. Check that the pitch-axis, roll and tail rotor trim are all in the neutral positions. Now connect the flight battery.
Remove the canopy and check the swashplate alignment. If it is not horizontal, you must correct it manually. Remove the battery and
turn the transmitter off. Disconnect the appropriate ball-link. You can adjust the pushrod length by turning the ball-link clockwise or anti-
clockwise. Re-connect the ball-link. Repeat this step until the swashplate is correctly positioned on the model.
Fine trimming is carried out at the transmitter during test-flying.
Check the main rotor blade attachment. The blades must be able to swivel smoothly, without jamming. They should not be too loose,
otherwise vibration may occur.
Blade tracking adjustment:
When the model is first flown, the blade tracking must be adjusted: slowly open the throttle and check the blade tracking with the system
running. If you detect a difference in blade height (tracking) at hover speed, then you need either to increase the pitch angle of the lower
blade, or reduce the pitch angle of the higher blade.
