Super Scout XL...dead rudder servo

[Masterguns]

Hello, people. I'm a man with many inquiries on my new journey with FT planes...
I'm almost complete building my Scout XL. I killed the rudder servo with too much torque I believe. I'm using four Surpass Hobby 17g. I've have good success with them & their motors before. Would it make a difference if I use one of my surplus FMS 17gr servos in the stash? Would it affect the Aura5 Lite controller with two different servos running on the same electronics? I had used the standard fare FT landing gear wire that I routed though a tail wheel bracket that I 3D printed that's very similar to the one's FT sells for their XLs. Lined the aft wire portion to be square with the coffee straw in the rudder itself & used a Dubro 1.5" light (the foam ones) wheel.

Perhaps I stripped the servo because the glue reinforcement applied after the bevel cut still made it too stiff & the servo just torqued itself to death? I think I will cut the rudder off & reattach with hinge tape or some of my plastic pin hinges. I think either of those two would help swing the control surface easier in my particular case. I've got Corona 22gr coming from HK which are known for better torque value & are still very light on the wallet. I've fashioned a new wire set up with some stronger pushrod wire that's more flexible & I'm using a salvaged 1/4" foam wheel. What do you say? Thanks.

Best regards,
Masterguns

No, a different servo will not effect the Aura, provided the servo is installed in exactly the same orientation.
There are 4 different orientations to install a servo, two of them are have one servo direction & two of them are a reversed servo direction.
If the new (or old) servo is installed in a different orientation, you may need to reverse it in the Aura.
When using any type of stability never reverse a servo in the Tx.

...Perhaps I stripped the servo because the glue reinforcement applied after the bevel cut still made it too stiff...

Very likely the case. When using a glue joint you must scrape it a thin as possible to prevent binding.

... I will cut the rudder off & reattach with hinge tape ...

This is what I use, but is is not necessary to cut it off. Just take an old clothing iron, reheat the hot glue & spread it out. A tiny amount of glue will be enough. You are looking for a control surface that just flops around when its free. Next apply tape (or paper) over the glue hinge & hit it again with the iron to reactivate the glue. I've never had this hinge fail.

..I've fashioned a new wire set up with some stronger pushrod wire that's more flexible...

I use the wire from marking flags, the kind used to mark utility lines. You can get 100 of them from a big box store like Lowes for less than $15.

Mostly the signal wires ( brown, orange, white or yellow) are just THAT, signal: high frequency low current. Red and black typically can run a couple amps (hot enough to fry the wires) cook stuff and start a fire in the lipo pack.
Most servos are universal, thatis if the connector fits, wire colors are in the right place, it should work
If you have a blue store for parts, they have a display of precision wire/ metal products somewhere. I found the odder wires they carry aren't precision so when you hog out the servo arm to fit, the next time it will either be too small or really floppy. Most Ace hardware stores have tubes of music wire somewhere, but the fabric or craft stores carry it also. SOMETIMES shopping with the wife pays off.
