Hammerhead goes wrong

[sneakyshot123]

Man i want to be a pilot when im older.

[fortyninepages]

Yaks are for milking.

[STRURM249]

I'm loving the contrailing prop at 0:27

[fortyninepages]

@STRURM249 why?

[GtaCd321]

Awesome, you could see the curve of Earth. !!!!!

[iionious]

@GtaCd321 that's cause hes using a wide angle lens...

[BarryAir]

this is hard to watch such sloppy flying

[westtexasduster]

Aileron does nothing at the top unless you've got full span ailerons. If the aileron has any authority, you're starting the hammerhead too early. It's performed moments before you reach the apex of the climb, by the time you've rotated 90 degrees you should be motionless and on your way into a dive. Use opposite rudder right before you hit the 180 degree mark to prevent inertia from going past 180 degrees. It's all in the timing and knowing when you'll top out on the vertical climb.

[RobertGary1]

Its hard to tell from the camera view but it appears that you aren't given enough opposite aileron to keep the plane from rolling coming through the hammerhead.

[glennjridge]

my God this makes me ill. I cant believe while I get butterflys at the slightest banking of a large commercial airplane when I'm on it, there are people essencially doing these kind of manuevers in essencially a small car up in the air. whoa...

[youdontknowxpand]

@glennjridge I wish I could do this... but there are no aerobatic instructors in my country...

[hensennejf]

Hello to all, The way the camera was positionned in the cockpit does not give a perfect view on what is good or bad... Hammerheads: it's full throttle, speed to initiate a loop, pull perfect vertical by checking your wings perpendicular to horizon, avoid any rotation by keeping the tips of your wings on a cloud or ground point, at +- 50 kts, kick in the rudder going WITH the prop. it seems here the right rudder. When kicking in, adjust "pitch" by pushing slightly the stick. L wing gives lift!

[hensennejf]

Even further more, to have the perfect vertical rotation around your yaw axes, it's quite nice to also put some opposite ailerons to counteract the roll, and there you will have your hammerhead. Start on a highway axis etc...

Next step for you... Flick rolls?

[NeverGiveUp8080]

try asking those 21 dislike people to give it a go...I bet they don't even know what an aircraft does...

[erniethefart]

wow why practice so many times? haha for my aero endorsement the instructor showed me everything once, and I did them 1 or 2 times, 3 at the most. And this was at a high standard flying school.

[LscKitzingen]

OK, these are bad hammerheads, more stalling than turning, but I cannot see a spin?

btw: spins are fun :-)

[drenajunkie]

Cool! have you nailed it yet?

[Laser200Z]

I'd say you were not vertical on the way up. It looks like you were on your back. That's why it doesn't rotate on axis at the top.

This is a good example of why you need to have spin recovery training before trying aeros.

[copperheadmarine]

What the hell was that? Are you getting too slow before kicking the ruddder? and what the hell is all that stick motion?

[Earssss]

i think u waited to long to hit full rudder

[hammerogod]

Hammerhead stalls are a real quick way to get into an inverted spin.

You have to remember that a Hammerhead is not a full stall.

A little bit of inattention mixed with slow responses and you have a perfect recipe for an inverted flat spin.

Several Pitt's & Eagle II pilots have found this out the hard way.

Having said that...Hammerheads are fun if you stay well ahead of the curve.

[MusicExXpertCo]

LIKE a G6 xD

[bucker26]

Hi, in Spain the stall turn is called "caida de ala" literaly fall of the wing. And I agree: it's a way to enter a spin (in Spain barrena) situation.

[c4nucksens8tion]

is that carb or fuel injected?

[maliknoman007]

where is wrong thing?

[JoshuaWGLloyd]

I stalled Upside-down in a Grob Tutor once and the engine shut-off, lool I was hanging out my seat and it was scary :P

[childsca]

I love how you can see the water vapor being pulled when it going slow.

[unapro3]

Make sure at the same time you "kick in" rudder, you give a quick spurt of full throttle, this gives a blast of prop wash over the rudder and helps spin her around at the top.

[dabb]

@unapro3

You are right, a russian instructor told me the same thing.

[thewhistler]

@dabb ahh that would explain it.

[aaron8862006]

@unapro3 - That has as much to do with the torque as the prop wash.

[unapro3]

@aaron8862006 I think you will find that tq effects the aircraft around it's longitudinal axis not the vertical axis which we are discussing here.

[aaron8862006]

@unapro3 - Precession, P-factor. Both affect the aircraft directly in the vertical axis. Spiraling slipstream also applies a portion of its force in the vertical axis. I used the word "torque" perhaps too liberally, but nobody refers to "left turning tendencies" in the aerobatic world.

[dutchvolvofan]

@unapro3 YOU ARE TOTALLY RIGHT !!!!!! nice to see another yak pilot !

[peytonxj529]

Looks to me like you are waiting too long. Lost too much airspeed.



[tailwheelflier]

while doing that in a cj-5, I accidentally did a tailslide/whipstall. Very violent, wake you up, for sure.

[b1cc2]

You're makign it too hard on yourself. Just fly the maneuver! Nice plane, and thanks for sharing the video!

[TheTodd2u]

Looks like you should have pushed a little more at the top. You were over vertical in the last shot.

[believeitornot28]

Theres nothing wrong with it its just ur piloting skills suck

[Pastushok24]

Yes, I`ve got such situations on this manouver this year, but now I do it and other vertical manouvers succesfully :) Month ago I took the first plase in Syberian championship in Tomsk :) Will download the short movie about it as soon as it will be created :)

[Airshowfan2]

LEFT PEDAL! Not right.

[gibbo1112]

@Airshowfan2 that is for american engined aircraft

[aaron8862006]

@Airshowfan2 - Really, Luke? ;)

[allegroracing]

I've been working on these in my CJ-6 and it looks like part of what's going wrong is you aren't using down elevator and opposite aileron at the top. While you're near the top, you should nearly have the stick cornered in the front left (for right hammerheads which are the only ones both our planes can do). You seem to only be feeding in opposite aileron. Check out Geza Szurovy's book, it's a great reference. Cool video though!

[blueflame53]

love your vids man.... +1 subscriber.

[alextankian]

How many Gs were you pulling in this manoeuvre?

[dabb]

@alextankian

I´m only pulling around 3 - 3.5 G´s in this manouver. This Yak52 is certified for +7/-5 G´s

[hjorleifur1961]

Hefurðu prófar klaufhammerhead? Þá ferðu beint upp og þrykkir svo á báða rudderpedlana samtímis.

[dabb]

@hjorleifur1961

þá er eins gott að halda fast í stýrið.

[dbowie2007]

wonderful video, keep posting

[avnavcgm]

Still looks like fun ;) Nice work!

[laleenmendis]

wow..dude that was great...

[pimpmytafel]

nice video, i always love your vids :) .... one question though, I'm not really familliar with aerobatic terms, what exactly is a hammerhead manouver?

[dabb]

@pimpmytafel

Hammerhead is also called a stall turn. You fly straight up vertically and the speed bleeds of fast. Once the speed is approaching zero you kick full rudder and turn the airplane 180 degrees around the axis and fly straight down. The first manouver in the video is a hammerhead. The rest is where it goes wrong and the airplane is entering a spin.

[pimpmytafel]

@dabb Oh, I see ... thank you for the info! It's great to see you're doing stuff like this, you're living the dream! I'd love to see more videos like this from you! Keep up the wonderful work you're doing :)

[WorthWatchingVv]

man it says 1 view. i am first.
