Hammerhead goes wrong

Me and a trainer doing aerobatics in a Yak 52 in Iceland in May 2011. We did about 30 hammerheads. I am trying to get a grip on this manouver on the Yak52 so I took a trainer with me. This is were it got wrong. The airplane was entering a spin at the top but we did the evasive manouver. Just to mention, I am spin trained on the Yak 52 by russian instructor Gennady Elfimov. The teacher in this flight was Magnus Norðdahl highly experienced in Yaks.

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.

@unapro3

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

[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

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

@hjorleifur1961

þá er eins gott að halda fast í stýrið.

Man i want to be a pilot when im older.

@STRURM249 why?

[fortyninepages]

Yaks are for milking.

[STRURM249]

I'm loving the contrailing prop at 0:27

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

[GtaCd321]

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

[BarryAir]

this is hard to watch such sloppy flying

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

[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...

[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?

[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!

[NeverGiveUp8080]

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

[dutchvolvofan]

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

[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.
