Can anyone out there do a knife edge spin with a Magic 3d?

i have been able to master hovering, flat spins, blenders, etc.., but i have never even come close to doing a knife edge spin. It is not the CG, thats so far back (5 1/4") the plane won't even fly straight, like flying a yo yo.

Thanks

Too much alieron will kill a KE spin. Try low rates on the aileron and high rate on rudder and elevator.

Don't you need aileron to hold position?

Yes but it is possible to have too much in some designs and that will throw the spin out of whack. For example my Midwest and H9 Extras will KES with full aileron (high rates) and remain stable, but I flew a CA 34% Extra and a Fiberclassics 35% Extra that would come out of it if you give full aileron. Different techniques for different planes I guess, and my example is roughly the same design too.

OK, Thanks, I am learning some of the more difficult maneuvers. Spins and circles are not easy for me.

KE spins are tough with some planes, the UCD makes them really easy, some of the smaller fun flys are tougher.

First, mixing down aileron with down elevator or just using flaps makes it much easier.


Up high, do a half a stall turn and when the plane is horizontal release the rudder and throw in full down. From there it gets tougher, you need to fly the ailerons to keep the wing vertical and feed in rudder and throttle to slow the descent and increase the rate of spin.

Too much rudder too soon and it pops out of KE, same for throttle. The hardest part is flying the ailerons to keep the wing vertical.

That's just one way but it works with practice.

Lets see if i got it,
My understanding of a knife edge spin is that i pull into a vertical let it stall and just before the plane reaches the KE position i give full throttle, left rudder, down elevater, and some but not all left aileron.

I'll try the lower rate of aileron today and see what happens.

BTY is the low rate of aileron also better for inverted flat spins? i can do the inverted spin but it is not really flat like the upright i can do. i can get it flat coming out of a blender, but i am still inconsistant.

Thanks

Thanks Geoharry,
I think am getting a feel for the timing now. i am thinking now that i would have to cross the rudder from the opposite direction of the stall turn to keep the plane horizontal. Also the aileron input is not the simple hold and forget that i read at another site.

I really don't have a good grasp of this manuever like i did with the others.

Can this be done using G2?

Yes, though the aerodynamics aren't quite the same. I can do them with the CPLR Cap and Quique Extra. Doesn't look quite like the real thing but you'll get the idea of what happens.

My H9 Sukhoi does them better on 3D rates than on normal rates for aileron. Then, reverse the rudder only when getting low for an inverted flat spin

You dont need full throttle, but some will spool it up faster on mine

Have fun!

Ive just started flying 3d with a 60 Razzel. Cant get the darn thing to hover but learned to do some decent KE spins today. the aileron was definetly the key to keeping knife edge going. Didn't discover that on purpose but keep noting how the nose would change attitude by moving the aileron back and forth while trying to do consecutive waterfalls. just kinda fell into the knife edge Too much aileron would definetly cause it to fall out of knife edge once it started.

Some planes you can get to KE spin by throwing the sticks a certain way, some planes will do it if you throw the sticks another way.

I like to get a feel for what the plane needs to do then have a plan and practice it. Get the plane on its side stalled, yes you are correct the rudder gets reversed but not too much too soon. Then throw in the down elevator with flaps to get it rotating. Fly the ailerons to keep the wing vertical. Slowly feed in the throttle to increase the rate of spin and rudder to keep it horizontal. You have the idea.

The Magic is tough to really to fly into a KE spin, it's small. Just takes more practice than the larger planes like the UCD.

It takes practice but that's the fun part
