flaps and analogues

air craft with hydraulically operated flaps (for example Yaks and Lavochkins)

Had hydraulic valves that the pilot operated to open, close and feather flow to raise or lower them.

The pilot could set them to any position between closed and fully extended.

Many controllers now have anologue dials, the X52 even has an analogue slider which would be ideal for simulating hydraulic flap control.

The further from centre you pull the anologue the faster the flap moves.

Non anologue players could still use the existing system as might those ac with step set electric flaps.

What about hand cranks?  At least some Me-109s had hand cranked flaps.

With the analog flap extender - what happens if you exceed the maximum speed for that amount of flaps?  Do they auto-retract or rip off?

Agree on the 109s hand-crank flaps - if they do some sort of analog fix that lets me put a bit of flaps out instead of the presets levels they have now, I'd use it.  Frankly, I'd like to be able to set my flaps and have them not retract automatically - let me rip it off if I go too fast, or give me some sound cue (like wing creaking) when I get close to the don't exceed speed.

Eagle I have the X52 slider banded now to  an on off hydraulic valve (no feathering)

There is a dead band in the centre and an outer bands each side.

The  outer band auto repeats the flap up or down command .

In the middle of a combat I can pull the slider back and flaps only come out when speed permits (but I do not have to touch it again as the auto flap speed thingy that HT put in regulates this for me)

If I go nose down and want the flaps in quicker then I throw the slider forward and they auto notch back up again.

This way I may be about to do some serious control surface balancing to hold my nose at low speed  (typically when bogie thinks he has roped me) I do not want to be trying to juggle flaps as well so with this slider set up I can "dial up" my flap need before hand and let HT's auto flap stuff do it for me. (as I slow so my flaps will deploy automatically)

Gamey? (pretty embarassing when you type something and read a row of W's on the radio line)

Well with an analogue flap extender all the analogue will do is set the rate of deployment like feathering a hydraulic valve.

HT's auto flap stuff will still sit over the top as it does now.  

Hydraulically I would look upon it (HT's auto flap stuff) as an over pressure relief valve. If the back pressure from the flaps on the hydraulics is too high then the relief valve dumps and the flaps will not open regardless of the valve position. Once the back pressure reduces the (and if the valve has been left open) flow will return to the cylinder and they will open until the back pressure increases to stop flow. If the back pressure increases even further (higher speed) then the valve dumps to the extent that the flaps are allowed to close.

How do you simulate a hand crank? well the hydraulic power plant has been replaced by the pilots muscles............... However the the mechanical advantage required to do this by hand would not allow the flaps to push the crank back round again so we have to think of HT's auto flap thingy as a spring loaded clutch.

Not a bad way to work it - I could probably set up something similiar by programming a button to continually send Q / W every few seconds when triggered.  

I'd still like to be able to have more flap control - it'd be nice to have one key to pop the flaps all the way down (hit the brakes), or be able to "crank the wheel" down one or two cranks and leave it there till I break something.  If unchecking autotrim left kept your flaps from autoretracting, that might work.  I want to be able to run it right to the edge, and RIP IT if necessary.   If I'm running with flaps out, either I want to slow down, or I want to turn and I'd rather take a chance on breaking the flaps then have them retract!

nice idea............... at 10 mph over the present retract setting initiate horrible noise...............at 10mph over that incurr flap damage......

Hmmmm how about the N1K2-Js...  N1K2-Js had automatic extending flaps (I'm not kidding, they had it really!).

Controlling flaps will be out of the question for N1K2-J.  It will be all automatic because N1K2-J has auto-extending flaps and this game has built-in auto-retracting flaps for all planes:p
