How do you do a "Lovecemak"
I know I spelt it wrong, but if there was one thing that got me interested in aerobatics, it was watching a full scale pilot execute one of these maneuvers...the PA announcer at the airshow said that the name was a Czech word describing the after-effects of some regionally produced brandy. I was amazed, and know that I have an aerobatic R/C plane I'd like to know how to do it!

How do you do a "Lovecemak"
Here's one way I do a tumble: On the 45 up line, I start a positive snap roll to the left. After 3/4 or so of the rotation, I cross the elevator to full down and watch the plane tumble. Models have a tough time doing a true Lomcevak because they don't have enough gyroscopic forces from their prop to start yawing the plane as it tumbles.

Along the lines with what FlyFalcon touched on, a Lomcevak requires gyroscopic precession provided by prop mass. Because of scale factors, models, especially smaller ones, have a hard time mustering enough gyroscopic forces to perform a true Lomcevak.
However, models can tumble and produce a similar looking maneuver.
My favorite tumble entry is very similar to Flyfalcons. 45 Degree upline, roll to knife edge, cross controlled outside snap opposite to previous 1/4 roll. (When I say cross control I mean like left rud, left ail and down elev, i.e., wrong side rudder or aileron.) Basically the same as flyfalcons but I roll to KE as opposed to 3/4 snap to KE. I seem get less roll in the tumble and more end over end business this way. I have also entered via flyfalcons description and that entry also works well. Great fun!
Cheers.

So that's:-
Full right aileron + full right rudder + full up elevator
and when the plane has completed about half a snap, you keep aileron and rudder where they are, and give full down elevator?
