Just purchased the new F18 70mm fan

Watching a video one of the people at nitro said he had modified to add workable rudders.

Is there anywhere where I can look to see how it is done?

Thanks

Because of the dual fins, I'd imagine the easiest thing to do is to put a servo on TOP of the plane to drive both rudders.
That servo faces UP with the control horn on top. You then use a straight two arm servo arm...

Pushrods can then be connected to your newly cut out and hinged rudders on both inner sides of the rudders.

The biggest difficulty is making a cutout for the servo, and routing the wires.

You can hinge the rudder with CA hinges, using foam safe CA, white glue or epoxy.

If you are using CA you should use the thicker stuff and do one side of the hinge at a time.

IMHO epoxy or white glue is easier though allow at least a day or more for the latter to dry.


Bare in mind doing this will really screw up the C.G. so mark it before you begin then rebalance the plane to the same spot when you are done.

Thanks for that info. Will probably do that even thought lot of people who have rudder on say the F-16 say its useless

Thanks for the help and info

Yeah. I really found no reason to do it.

Even in a cross wind the plane floats in so well that you can typically bring it in at an angle to the runway, then let it drop and land in the width of the runway.

You can also turn it in just before landing to align as well.

I haven't bothered with the rudders as I don't miss them.
