[An online discussion from the IMAC email group]

All you 3D flyers, How is a blender done? How hard is it on your plane?

Its really simple actaually. You need "3D" elevator rates, ie 35 to 45 ish degrees. Go to hi rate elevator (and rudder if you use D/R). Get altitude. Throttle back to idle. Push to vertical downline. and push full left aileron so you are comming straight down rolling left. Then add full down and full right rudder, ie negative snap input. Thats about it. After the plane quickly flattens out add a little power, or at times the engine may try to quit.

You forgot one important thing.........use someone else's plane at first :-)

A couple of kind recommendation from somebody who suffered a loss of his Sukhoi on that subject :

  1. Take enough altitude before starting the dive
  2. Don't put full gas on the bottom of the dive to make the spin more violent.
  3. Don't try to wait for the freestyle music tempo to match the entry of your flat spin, time is running fast when you dive vertically !
  4. Don't keep your damn finger so long pushing the down elevator when you see the ground coming closer to your plane, it doesn't really help when you are stalled !

Oh well, so much for my first freestyle !!

Hi John, Contrary to what any body says it is very hard on your plane. I broke every robart hinge, 5, on my rudder doing it repeatedly one day. I pprobably did it at least 10 times, one guy even thought I had a variable pitch prop because of the wonderful sound it makes. At any rate, get some altitude, push straight down at idle and start rolling left, just when the roll rate is ballistic through in a negative snap input, ie left aileron, right rudder, and full down elevator. It will sudden;y transend into a flat spin and the sound off your plane will convince you of the forces exerted on your plane. Thats why Que Qiu does it after only a few rolls I'm sure.

Hope to see you soon.

Mike, I was at the field with Bubba Spivey (Lanier) the other day, and he pulled one of these out of his hat at FULL THROTTLE. I'm sure it's been done before but I've never seen it. I think this is the way he stress tests all his kits. It was enough to make me pucker! :)

Thanks to all that answered how to do a blender.

Apparently, the control inputs are not hard but the manuever is on your plane. I Did a few yesterday and they are pretty cool. Although I will not do them one after another every flight.

My extra did them beautifully as it can flat spin very well with 45 to 50 degrees elevator. I used the approach of feeding in a small amount of the controls a split second before giving all of the throw. Also the hint of a small amount of power is good because the trick wants to slow down the motor a touch and the power really gets the spin flat. If the trick is done close to you, you actually can hear the wind noise as the plane goes from vertical to horizontal and the wing going flat against forward motion acts like a huge air brake.

BTW, the trick is fun to watch but is in no way a scale like manuever.

Have fun blending your 3D soup.
