I was taught to bring the nose up to about 15 degrees then full aft elevator and full rudder. Is the difference because of airframe (I was using I Cessna 152 Aerobat) or personal preference?
It is a certified airplane making adjustments to the shape of the spades illegal. FAA FAR 23 certification requirements specify positive yaw roll coupling and Extra had to shape the spades this way to receive certification.
It isn't a problem for inside snaps because a little aileron into the snap helps with rotation rate. Outside snaps are very difficult in the Extra 300 because you have to "fight" the spades. I believe that Extra improved this on the 300L model with flat spades.
How does pitching back down help? Wouldn't that unstall you? I've done snap rolls in a Super Decathlon, and the way I was taught was to keep the stick straight back until about 3/4 of the way around, then recover. Very different airplane, of course.
Keeping the nose down during the snap roll increases the rotation rate dramatically. It is very similar to a figure skater pulling their arms while in a spin ... as they bring their arms in the rotation rate increases. (conservation of angular momentum)
The rotation rate itself keeps the inside wing stalled due to roll induced angle of attack. The descending wing is moving downward so fast that it actually stalls itself.
@jjohnston94 I certainly agree.....maybe we do snaprolls different here in Kansas....we do what I call a "horizontal spin"....and that's exactly what a "snaproll" should be......fully stalled with horizontal travel until recovery.....I think Leo would agree !!
Awesome Video, I have only flown a .6 or so in an Extra300L, on the Monday after 07 Red Bull Air race down here in Perth, did one snap roll but as PAX, I flew many other moves on the stick tho, I love aeros, have only just started doing them in a C152, you can check them out if you like at my Channel...still refining the recovery :)
it would be nice to have a cockpit gorpo, showing from overhead the stick, throttle and pedals!
Do you apply forward stick after the wing stalls, during or before ?
With forward stick, isn't an outside snaproll ?
Thanks

Why do the angled aileron spades require rudder and aileron coupling?
Also, what's the difference between an inside and outside snap-roll?

damn nice!

it would be nice if there is a chase plane to get the outside view

Are you the pilot in the video? Nice work

during a negative snap roll do you use opposite rudder to ailerone imputes or the same direction or it dosnt matter just currious thanks.

so is that rotation purely off of applying the right rudder, or is right stick used also?

I try to minimize the aileron, but you can see from the video that about half aileron deflection was used.
The ailerons on the extra tend to deflect automatically when you apply rudder. This "coupling "is caused by the angled spades.

Would adjusting the spades help or do you prefer it this way?

The extra 300s is an amazing aeroplane! It snaps so fast!
