$95 is pretty cheap insurance in my books one could damage their plane if the rubber bands pinged when landing I asked around and everybody said rubber bands were crap so when i was looking for some bush wheels and found the struts too my worry was over!

Will give these a try. Around the size of a manīs wrist. More flexible than O-rings, but less than normal rubber band.

For the record when using rubber bands, generally when 1 or 2 fail you'll notice the sag before complete failure, so no real concern for damage. It's just a hassle to have to replace so often.

How do the PR Bushwheel shock struts work? Is there a spring inside them or something else?

Has anyone programmed Futaba 8FG Super for the Super Cub? I would like to have two-stage flaps and elevator mixed to the flaps so that there is some down elevator on mid flaps and some more on full flaps.

I used the motor function to slow down flaps, and I have only managed to program down elevator on full flaps. None on mid flaps.

Might also consider programming in some aileron differential while you're at it.

Word of advice, the SC needs a healthy dose of down at both stages but especially full flap, to the point that dropping full flaps w/o elevator comp will result in a loop.

Not trying to scare you, just prepare you.

As for the Futaba radio, can't help you from recent memory but you might tinker with the offset on the mix that should slide the start point from mid switch to top of the switch but it's been a while

This is how my flap/elevator mix is done on my Futaba 8FG Super. Motor (virtual channel) is master to both flap and elevator as it is possible to slow down the servo movement that way.

Flap is connected to three-position switch and works as intended. The mid servo position is mid flap, the other "turned" servo position is up flap and the other "turned" position is full flaps respectively.

The elevator is a problem because the movement in the mix must be 0 to the other direction so that there is no up elevator. I just haven't found a way to adjust 5mm push on the elevator on mid flaps and 12mm on the landing flaps.

At the moment, as said, there is no push on mid flaps and some on full flaps.

Any help would be greatly appreciated.

I'm too tired from being out in the sun for 3 days to analyze why you're using the motor as the master but you need to change the offset

offst as its displayed there.

You want to offset the start point of the mix.

Hi

The motor is the master because that enables me to slow down the servos when flaps are deployed. The instruction I used is here:

http://www2.ripmax.net/Futaba_Inform...Servo_slow.pdf

I will try to alter the offset once I get back from summer cottage. Although I think I did try that already.

Asked for instructions from Futaba and got them!

I was told to get rid of the motor as master function as "mixing to the motor digital channel messes the elevator up too much."

Did that and made this mix as per instructions and at least on the "servo" screen it looks good. I just needed to replace the "OFF" on the second page with a "+" so both elevators work in the mix.

Upgraded my Cub with the custom shocks from PR Bush Wheels. They work a treat! Money well spent.

Also customer support was top notch.
