My variation on the Lomcevak is going right to left in a 45 degree upline roll to knifedge then peg throttle rudder stick to the upper right corner at the same time full left aileron and down elevator. The Lomcevak is a very impressive.

There are many variations of the lomcevak, even how to spell it and pronounce it. In my book, what you describe above is a left outside snap roll.

Yes i thought when i first looked at the manouvere that its basically a negative left snap roll as the inputs are very similar, but its really not. The key difference is that you are using full down on the elevator and entry airspeed is critical tso that there is enough momentum to get the tail to rotate in front of the nose through the line of flight. Clearly if this happens it is NOT a snap roll. In a snap roll generally you are using only a hint of elevator , neg or pos, and only using it at entry into the manouvere then releasing as soon as rotation starts. As Mike points out early in teh tutorial the snap is not as many have been taught a simple sticks in teh corners manouvere there is a lot more to it than that and using full deflections on all surfaces usually produces a rather ugly, over deep and difficult to control snap.

This'll also happen if lateral balance has been acheived by adding tip weight. Goosing the throttle will cause the plane to try to yaw laterally towards the weighted wingtip because the mass is farther from the thrust line that the mass it was fitted to counteract. The only real solution there is to scrath build, weigh all the materials, install all the heavy stuff along the centerline (side to side, up and down) THEN the prop wash swirl will be the only thing to contend with

i found to get into a low hover is to come down the runway like you going to land, slow and low, not much throttle at all, a few feet high at most, then when in front of me or just past me(where i perfer), i give elevator and goose the throttle, like a wall but in slow motion, and the throttle burst almost pivots the plane to upright with gaining altittude, a few times and you will see it works very well imo

Easiest way to enter a low hover is from a simple harrier.

Ya, I hear ya,

We just lost our oldest member a few months ago. CB was 83yrs young, and flew right up until his passing. Granted, he could only fly about 150yds, then handed the TX over to someone as he could not see the plane anymore. But, that 150yds kept him coming out around once a week, it was a pleasure to meet him. His AMA # was 4 digits !!!!! Greg

Hey Rod Bender , I was wondering if your from the Cameron Park Ace Hardware ? Ive shopped there a couple times for plane stuff .
I was reading about your friend CB that passed and your statement about the old being intimidated .

I was unable to fly at my club (SAM's) cause a pylon race was going on so I went to the Mather club . I met an older gent named , Rodger Grotheer . He must be somewhere between 70-80 years old . I found out he has a new sponsership with Airtronics while talkin to him . He was flying a Kadet Senior with his own designed "Barn Door Ailerons" . He was flying low and slow doing aerobatics that made my jaw drop . Found out later he was sponsered before for pylon racing . There are some old guys still out there that us young guns have nothing on . By the way , he did show me his AMA # and it was 4 digits too . Probly has an 8 digit SS # too .

If your from Sac area what club you fly at . Eldorado flyers?

Im learning 3D, well hover, then 3D on a ParkZone Typhoon 2 3D. Is that a good plane to learn these maneuvers?

The bigger the plane the better to hover. I have a typhoon and never fly it
