Sorts out that AOA at the wing ends ahead of the ailerons being set lower than the tip for a delay of post stall wing drop...... however .... no matter how you delay the stall with your style of flying..... when you do..... the wing will fall away fast on this ship....... it is not a docile trainer with all the safeguards.......,.... it is a machine meant to be "Mean"

Reflex aileron only applies to high speed drag,not to tip stall. Check attached pic of split? flaps on a Me 109. Dual purpose. 1. Airbrake 2. Inboard spoiler inducing root stall enabling aileron control at low speed. German enginering circa 1936.
inducing might be wrong word.

Very True ! ...... in every aspect .

That is why I was "careful" to mention in my semantics of description, that it affected the AOA of the Wing Profile ahead of the Ailerons and not the Wing Tips as associated with the "Tip Stall" terminology always used here.

Reflex still applies though, for inducing the "Washout" principle without twisting or warping the wings and the overall effect does play down the early stalling of the outer section of the wing , and would also tame the wing tip stall when it happens , as the the aerofoil just inboard and next to the Tip ahead of the ailerons is not at its same high AOA as the Tip, and still flying so to speak , supporting that stalled Tip !

Reviewing that interesting pic of the Bf109 above, the inboard Root Spoiler modification to work with its mated Split Flap would act more as a Dive Air Brake or "Crow" like sailplanes incorporate.

And talking about Reflex again...... I have that dialed in on the FMS 1400mm 109 too .....

Hmmmm!

Look at the attitude of the 109 HJ ! He is in a climbout with his wheels retracting. He has a fair wack of left stick in as indicated by the right aileron. (Perspective makes it look like a outer flap). Now I got myself thinking again. I saw a 109 a 100 years ago and read the explanation of what was the purpose, but cant remember.
MK 24 on the doorstep next week. 65hrs on the sim flying Airfield Corsair and then changed mind to Spit. Closest thing on my sim is 39 inch Great Planes electric Spit. You werent kidding about the smaller planes going out of sight quick. I had my nose on my 40" monitor.
Cheers!

Huh? the right aileron is not deflected in that picture! The inbd and outdb flap are deflected down and the aux upper surface flap is deflected up to improve cooling to the radiator.

Thanks HJ!

Tom put me in right direction. 109 radiators are sunk into wing for streamline.
Run hot quick on ground. Upper flap opens to get heat out. There is boundry layer slot between upper flap and wing so no flow separation.
4 checks at HK so MK 24 on the way for next Friday. Appreciate all the hi res pics of your install. Will copy except maybe for custom length wiring on everything and some bushpilot 2.5 mains and 1 inch rear and the doors clip.
Cheers Oz!!
PS: Dont suppose you tried it on skies Eh??

Now that's a thought off the flat hard smooth beaches in Broome ...... but you're sure to snap the stock prop in any nose over with the extra ski drag.

Enjoy your build IGU1 !
