P-51 Washout

Dear Mave,
The outer portion on both wings are slightly higher, not much through about 4-5 mm..

The theory:
At low speed and high angle of attack, the inner wing will stall first. While the outer portion, with the aileron higher has yet to stall..

During this time, the inner wing would have lost some lift force, and the plane would nose down resulting in a stall that is easy to recover provided there is some height available. All these happens while the outer wing have yet to stall, hence no spinning out of control..



After you have done the cutting and re-attachment, set both aileron in neutral positions. The outer portion should be flush with the wing-tip when viewed from behind, while the inner portion should be slightly lower than the wing root at the fuselage.

You may need to re-trim the plane to give 1-2 up elevator. Climb to a high altitude and slow the plane down and kick in full up elevator to see the nose-down instead of tip-stall... it does wonders to a pilot confidence to know your plane will behave in a predictable manner.


Cheers,
Leon

Stunts

P&P,
Yeah man, it was fun though...

You not too bad yourself wat.. missing twin rudder on your electrajet after that ultra-low-inverted stunt...

My point is.. when a pilot is really confident in a plane he/she will forget about safety when pushing the envelope. Let's keep our planes healthy and long-life...until we start to accmulate too many NIB kits...

Cheers,
Leon
