Lumciavak

[SnoJetter]

Not sure if that's spelled right, but I'm wondering if anybody is familar with this maneuver. It has got to the most exciting maneuver I've ever seen a plane do, but you just don't see it very often from full scale or models - I suspect that's cuz it's so hard to do. Is it even possible to do it with an RC model? How is it accomplished (stick inputs)? Actually, I've never seen a modeler attempt it and only a couple of times with a full scale plane - and just on tv.
I saw a movie a while back called Cloud Dancer. I think David Caradine (Kung Fu guy) was the star. Anyway, he was an aerobatic pilot who flew competition and had dreamed up this new stunt he called the "Cartwheel." Well, it was a Lumciavak and the story was he wasn't in good physical condition to attempt the maneuver, but he needed one more competitve win before he could retire...well, you get the jist. I enjoyed the movie but haven't seen it for a while. Anyway, that's where I first saw the maneuver and since then I've wanted to see more of it. It's crazy to see a plane flip around in the air like that - AMAZING!!

It's very easy to do, but to make the flying either side of the maneuver look pretty is difficult.


The best aircraft to perform it with seem to be the CAP, Giles and Sukhoi ....... however, I've seen an R/C Messerschmitt 108 do it very nicely!!

To perform:

Fly a 45 degree upline, roll right to knife edge, hold a small amount of left rudder. When ready to lomcevak, add full left rudder, full down elevator, and full left aileron. When the model is in a good place to stop, probably nose down, unless you get really good, centre the sticks anr recover, remember that you are likely to lose a bit of height at first.

Generally, the higher the elevator rate, the better!


Full size aerobatic aircraft do it very well, they can control it to the point where they can lomcevak consecutively at the same altitude,and maintain sideward movement. Very clever maneuver!!

Hope this helps, it's only the knowledge I have, and I don't make myself out to be an expert, but the above way works well with my models.

Edge540,

Can I get your opinion about the Hotties that Watt-age have in the market right now.

The CAP 232.
Extra 330L (been out for a while).
Giles G-202.

What do you think of these three?

Thanks,
G.

[Edge540]

Well, I'd never heard of that company before!!

Their Giles looks the best of the three, followed by the CAP.

If I were going with one, I'd take the Giles. Just last night I was actually flying a 1/3 G-200 ..... they fly really nice, and they lomcevak fantastic!

I can't imagine you'd be disappointed!

***If I were going with one, I'd take the Giles**

thanks Edge,

My heart is set on that:)

***Just last night I was actually flying a 1/3 G-200 ..... they fly really nice***

Is that glow or elec?

***I can't imagine you'd be disappointed!***

I'm loving aerobatic planes right now;) :) :D :cool:


Yours,
G.

Hey Edge540, thanks for the info on the Lomcevak. I think that is the prettiest maneuver out there, but I'm a looooooong way off from even buying a plane that can pull it off. But it's nice to know that it can be done with a model. Thanks,

Kyle

2NG: The Giles i was flying was powered by a great big gasser!!! mind, it had electronic ignition!!


SnoJetter: I've spent a few long flights today experimenting with the lomcevak with my Edge.... here's what I've found.

To make it real pretty, fly the 45 upline at full throttle. roll right to knife edge, hold left rud. add left ail and down ele, release aileron and reduce rudder, wait for the tumbles to slow down, and it should turn into a waterfall, then control the vertical heading with the rudder, and once you';re flying to the stage that you can do a waterfall, you'll know what i mean!! Have a look in advanced aeros on my site at www.aeroforce.co.uk .... it's on there... somewhere!!


All for the future, I understand, but you'll get there if you put the effort in! That's how I do it, at least 60 minutes in the air per day is really perfect for progression.... although that's only 3 flights!!

I agree, it is very pretty. I wish I could've had one of them today on film, couldnt get it right every time, but one fo them, was absolutely textbook! And there was me thinking my Edge wouldn't lomcevak!!

Thanks for intrigueing me to try it, all awesome stuff :)

[2NG]

Get into Eflight, EDGE540, we need your skill and knowledge in flying in here...... I will be dissapointed if you don't, at least get one electric plane:mad:

[SnoJetter]

Edge, I'm slowly workin' my way in the aerobatics direction - did my first loop last evening...sorta. Didn't quite have enough speed to complete the loop and it really just stalled at about 60 degree angle on it's back - gravity did it's part in completing the loop for me. I tried one more time, even less speed this time and almost ended up doing a hammerhead by accident! :D I'd LOVE to see a picture or three of you doing a Lomcevak on your website. Let me know when you post 'em.

Kyle

[Edge540]

I do have electric, I have a Multiplex twinstar!! not very good, but got two consecutive rolls out of it last night!!

Sno: With your loops to get more speed, get height, full throttle, push the nose down a bit, and smoothly pull up Important thing is keep the wings level and not to do it too tight. What model are you flying??

I'll have a look at a video I have of me flying here..... I'll try to find out how to change it from DVD format to one that you could watch!!, if not, I'll take pics from it. That's if there's one on it!! Sure there is, but it's not very graceful, as it was filmed in the early days I was doing the 3Dish aerobatics. Now with my Edge or that Giles, so to speak, the larger models, I can do them with a really slow and graceful tumble, however, it was much easier with the CAP and Giles, the Edge is all about timing.

[Edge540]

here's hoping that this works!! Sorry about the poor quality, they're of my Kyosho CAP 232, and they are screenshots from my club video. The first is hopefully a knife edge, followed by part of the lomcevak (i'll try to get a video, I cannot possibly demonstrate it in pics) ... and the third is me and a clubmate flying a formation display.

[Edge540]

heres the lomcevak. as i said earlier this model performs them less gracefully, hence the blurred pic!

[Edge540]

and the formation

[2NG]

Edge,

That looks sweet:)

A year late but maybe you will still benefit.
I have had good luck getting planes to "LOM" ass over tea cup by doing the following....
Establish a 45 degree upline at 75% power. Begin rolls to the left. After say 2 and 3/4 rolls, reduce aileron input to about 20 to 50% add rudder (20 to 100%) and stab full DOWN ELEVATOR. May need to increase power as well... this is a GYROSCOPIC manuever. Be sure to use a heavy plastic prop rather then a light wood prop. I have never had 2 planes that would lom the same way. Others liked to enter it from a 45 climbing snap... gotta just try stuff...

Maybe try to download this one. Full scale Extra 300, attempting some interesting maneuvers(and sorry for my english:).Go to:

and click on-----> film (8,4 MB divX4)

[Somethin_Extra]

Little known fact:

The "lomcevak" is Czekoslovakian for "headache".

Very appropriate!!!

I never could figure out the Chech language.

[tigil]

I try to make locevak w Real Flight W extra 300 may be am not make it in a good way


I put the plane up 45 d and swing it on knife edge w just old a bit the ruder and after to make the figure I put to full the ruder and full down elevator at the same time

the figure i make not look so good
if someone have video of that I think its a best way to learn this fugure

[tigil]

I downloaded the USUL video Pretty good !! am not shure but I think the lomcevak is in this video at the half of it

[LEMMEDRIVEIT!!]

Hey guys,

Well, I was so confused about what a lomecevak was (sp whatever) lol i found a video of a real plane doing it online, with cameras on the plane. Check it out, its pretty cool, worth the video.

Just go to the bottom and you'll find a few differen't formats.

Later

[Giles-G202]

I just ordered a Giles G-202 Arf. I'm putting my Saito 180 in it. Glad to hear it's a good flyer. Thanks for all the info...

[xtraflyr]

Ive also found out that a heavier plane will do it more gracefully also. My old school Midwest Cap 232 does it awesome.It's a heavy pig of a plane but does the snap stuff beautifully.. The lighter 3d planes kinda flitter through the manuever...

cya,
