New Flaperon Mixer system

4 posts in this topic

I'm wondering if I should be wearing my flame proof clothing for this but what the hey. 

I designed a new flaperon mixer system that I'm about to start fabricating.  75% of it is copied from the later model Kitfoxes,  main differences being that the assembly is mounted to the tubes that divide the cockpit area from the tail cone and instead of having a single axel that has the control arms for both flaperons, Ive split that into right and left sides(red and green in the pic).

Reasons for doing this are:

1. Wanted differential in ailerons

2. Free up area behind seat for some baggage

3. No need to add additional structure to support mixer

4. No need to re route rudder cables

5. Loved the challenge of designing it.

Cons:

1. More complex mechanically(but not more than the old system).

2. Need to disconnect pushrods top fold wings. 

In the pic the purple portion is the flap mechanism and works just like the kitfox system. The blue portion reverses the direction so so the green and red move differentially. 

If it's not clear I'll show pics when it's built

Well done!  I kept it simple in my conversion and just copied the Model 4 mixer.  Meant that I had to modify my fuselage to attach it.

Yeah I traded a little complexity in the mixer for simplified mounting and not having to reroute the rudder cables,  i also don't have to cut the control horns off the flaperons themselves. 

Just alittle detail design left to do and order material. There's a lot of  parts that'll be laser cut and parts of the assembly are almost self jigging.
