Dont use the grease, 3in1 oil or similar, not WD40, will be ok for the shafts, if oil dont work on the rudder then use the Graphite spray, but first try to find the cause of the binding, possibly, you have tightened the rudder horns to close to the rudder posts, just lift them a little to see if it loosens them
To be honest, I have never heard of the stuff, hence no comment!!! I will only advise if i have used the item or product. Do you think you will need that? Possibly WD40 would work just to dispel any moisture, If you spray sealed the circuit boards it might make it difficult to alter the wiring etc, only a thought as i said i have never used the product
Thanks for that. I have picked up one or two references elsewhere that coating all connections made in wiring and servo connections is a good precaution. Also coating exposed circuit boards would benefit them. It is extremely unlikely that I would ever wish to make alterations to such boards, so if it does no harm and may be of benefit then I will have a go.
You were right on the rudder links Mark. Better now that I have given them some 'slack' so will just use 3 in 1.
