No tail rotor servo :o

After a small crash with my Honey Bee King 2 it took me about a year to get replacement parts. Now that I finally have it back together I got all excited only to have my tail rotor servo stop working. It worked just fine in the garage after fixing it but suddenly took a poop. A simple $10 replacement servo did not fix it. Unfortunetly I am new to the helicopter scene and know nothing about the electrical schematics of this thing. (i.e. the gyro). I do not know if my reciever is not working or if it might be the gyro considering my tail servo is linked with it. Any help is much appreciated.

p.s. I was able to do some low hovering after setting the tail rotor at a fixed position.

Hi spankyfrank05,

A servo tester would tell you in a jiffy, without one the easiest way to check a servo is to swap the rudder and any other servo plugs in the receiver and see where the problem goes to the tail servo or the one you swapped with.

It may also pay to try unplugging the Tail servo from the Gyro and plugging it directly into the rudder output on the Rx to see if the Gyro has a fault.

Also I have found the the DOA rate on cheap servos is high.

Hope this helps.

Sounds simple enough. I didn't even think that the newly bought "cheap-o" servo could be DOA. i'm guessing the gyro is ok considering I was still able to hover somewhat steadily without a tail servo. i'll give your suggestions a try.

Much appreciated!

Hi spankyfrank05,

Don't discount the Gyro too early, the Gyro works through the rudder servo if the servo is faulty you were getting no input from the gyro anyway.
