ARTF Servo help

[Jannie]

I've just done my maiden flight with the Heron Glider. Almost lost the plane due to the aileron servo going berserk. I have read the comments about this issue on forums but how do I remove the servo as it is apparently glued into position? Cannot remove the thing without damaging the wing. Any advice?

The servo problems are usually as a result of a voltage or signal degradation with the long leads. Check that all the plugs & sockets are really clean & making good contacts, with a good voltage available to the receiver.

 

Then if you still need to replace just run a modelling knife blade around the edges, minding the lead, & lever out with a wide thin flat blade, like a table knife. The ARTF's come out quite easily, however if it has been constructed from the kit & cyano'd in then it may be a struggle & impossible to extract without some damage. Fit the new servo with UHU Pro.

 

....and welcome to the forum!

Maiden a NIB HK glider with digital aileron servos recently and during bench setting up one would intermittently miss center so replaced both as one was faulty despite checking everything out.. 

 

Bit of a pain in the wallet, but I suppose you get what you pay for?

I have seen this with 'some' ( say no more ) popular radios, it worked with my Futaba and a servo tester but not on the club members  **** radio.
