A rotor button and cap may hit together due to several reasons, including improper installation or alignment of the distributor components. Worn or damaged components, such as a faulty rotor, cap, or ignition timing misalignment, can also lead to contact. Additionally, excessive play in the distributor shaft or incorrect rotor height can cause interference. Regular inspection and maintenance can help prevent these issues.
Broken rotor button.
The torque from the main rotor would cause it to spin uncontrollably.
proly needs a tune up most likely plugs wires distrubutor cap and rotor button
To counteract the force of torque created by the main rotor. If not for that tail rotor, the torque would cause the helicopter to spin continuously around.
Bad coil Bad rotor
Yes, they could.
Typically, when setting the timing initially, you would want the rotor to point to the #1 wire on the cap.
Warped rotor(s).
Check the coil and replace if bad. Should fix the problem.
Assuming you mean distributor cap and rotor, yes, if you mixed up the firing order.
Bad coil, rotor, distributor cap?
I would try distibutor cap and rotor.
