Feature request: detailed aileron, flaps and empennage

[tonghuix]

After the flight training, I relized that our exterial 3D model is not such accuracy as a real Cessna 172. So I take some photos.

Ailerons

Cessna 172's ailerons are differential-type but Frise-effect aileron, ref here, and also Chapter 6 in PHAK (Pilot's Handbook of Aeronautical Knowledge). It deflects 20 deg up, 15 deg down for compensating adverse yaw. And also the ailerons have Counterweight for balance inside the gap between aileron and wing (ref here and here). And I discoveried that when the aileron deflect up, the bottom of the aileron also has a little downward (about 1cm) than the wing bottom surface which could also produce some drug but less than typical Frise-type aileron (some discussion here).

Flaps

Flaps just needs more detailed for actuator and connection parts. C172's flaps are single-slotted-type flaps, so when it deployed a slot should appear.

Ref:

Empennage

First of all, the elevators and rudder have a horn balance part. The horn balance on elevators are more obviously. Ref here.

And also there should be some 'holes' for linkage between elevators and horizonal stablizer.

And could you please add a axis for elevators, and more texture detail for inner between rudder and elevator:

@tonghuix Nice detailed reference material, thanks for providing it. Now all we need is someone with the time and drive to implement all of it :smile:

I took a look at this and while I improved the flaps greatly with the work I did awhile back I see I made some mistakes. It looks as if there are only two actuator and connection parts per side VS the five I added. The slot that becomes visible when deployed wouldn't be hard to add but I would want to remove the extra actuators and limit it to only the two.

Hi @tonghuix, I just discoveed your Chapter 6 in PHAK (Pilot's Handbook of Aeronautical Knowledge) document. Very interesting, very well explained.

Thank you.
