The way I do it is to get some height, point it straight to the ground with about 1/2 throttle. After it picks up a good bit of speed, start into a aileron roll. After at least 1 or 2 rolls, jam the sticks into the top, inside corners.(full throttle, full right rudder, full down elevator, full left aileron.) The more surface deflection, the better but I recommend no more than 45 deg. in high rate for most planes. A big ole honkin' engine helps a bunch too. I have found that some planes wont blender at all, like my GP .40 size extra. I suppose not enough control surface area. The more speed you have when you enter the spin, the wilder the spin. It's sometimes followed by a flat spin and a tumble. It puts a lot of stress on the air frame, most of the stress will be right behind the wing. I have heard of more than one breaking in that spot, so I added some extra light ply gussets in my fuse. It's really just a timing move, that is very easy to do. It's sorta like doing a snap roll while diving straight to the ground. I have a H9 1/4 scale Cap that will do it very well also. Give it a try, and make sure you have plenty of surface throw. Have fun.
P.S. I'm not one of those "expert" 3-D guys but I can hammer out blenders all day long. It's only slightly harder to do than a snap roll, but is the most heart stopping maneuver you will ever see!

Here's my DP .40-sized ARF, powered by a YS .63.

green river rc - thanks for the blender description! I've tried them, but they never seemed to wind up that well. Now I know why. (I dive and pull the throttle back to just above idle before rolling and snapping the plane.)
Half-throttle snaps while exiting a turn with this bird are neck-breakers - a properly-executed blender should be stunning. I just hope the tail remains attached!

Here's a pic of my Direct Connection Ultimate.I don't put pilots in my planes,so a guy in our club made this and sent it to me.

Heres My 3D machine... absolutely fantastic plane. I landed it INVERTED! the other day after an extended hover and it overheated. Very minor damage. Repaired and re covered in 2 days, cant even tell it happened. Still flies and looks exactly the same as it did.

By the way. Knife Edge loops require a LOT of power and finesse. You have to have plenty of rudder authority too. I have stripped elevator servos doing knife edge loops. That takes a lot of force. They just take practice and on an ultimate you have to have your mixes for coupling and roll coupling right. PLay with your mixes until it tracks straight as an arrow and doesnt try to roll out or pull to the wheels or canopy. Once you can do stright knife edge with nothing but rudder input, KE loops will be a snap. Just remember that you MUST get out of the power as you come over the top and give it full rudder and get back in the power on the backside at the 9/3 oclock position. Get into the power too early and you will rip the plane apart.
Blenders.
HIGH rates. 60 degrees down elevator, maximum rudder and aileron throw.
1. Get the plane up high and back down to about 1/4 throttle and push it into a vertical dive and throttle up to about 1/2 throttle with full left aileron
2. Make about 3-5 rotations ( get it rolling fast straight down) and simultaneously give full left aileron,full down elevator, full right rudder and full throttle. The plane is going to wind up like crazy and end up in an inverted flat spin.
3. As soon as its spinning upside down, back off to about 1/2 throttle (or whatever it takes the nose up in an inverted FLAT spin) and let the ailerons come back to center. Continue to hold full down elevator and full right rudder.
Let it inverted flat spin as long as you dare. I will typically exit by backing off to 1/4 throttle, let the controls come to center, give a little left rudder to stop the spin and fly out inverted or start an inverted rolling harrier or something.
Another exit is to stay high enough to just put it back into a vertical dive into the wind and fly out upright.
Note** Be careful.. Biplanes can be really tricky to get out of an inverted flat spin. Be sure to practice up high so that you have time to work your way out of trouble. If it gets stuck in a spin normally rolling out with opposite(left) rudder will get you out of it.
