Im trying to learn this.
Any helpfull hints.

I've been practicing these for a while now and this is what worked for me.

First I did regular slow rolls (while maintaining altitude) so I got both thumbs working together (ie rudder + elevator).

Then I entered a harrier and applyed some aileron and added enough rudder and elevator input to keep the nose up. You will need much greater rudder and elevator input here then for normal rolls.

Do the guys at TOC use elevator?
I thought it was just rudder?

i use quite a lot of rudder and a little bit of elevator.
I found that if you want to get the rolling motion just right, you have to use mostly rudder, and then feed in a bit of elevator.
Before when i was just slamming in elevator and rudder, they just looked like nose high rolls, but they didn't look nice, and were harder to control.

Probably the type of plane you fly has some effect as well. I just fly a Laser 3D and I find that I need both inputs.

practicing holding a plane steady by not loosing height in every position while a plane is rolling. whatever it takes to keep a plane off the ground while inverted i.e. a small amount of elevator depending on how you have your bird balanced. what position it takes for your plane to hold this/that side of knife edge i.e. left or right rudder. the hardest thing will be for you fingers to keep up with the correct inputs, the timing will come with practice. it takes more rudder than elevator again depending on how you have your planes balanced, I have most of my birds balance for hands off or very very close to hands off inverted so very little pushing or pulling is needed on the elevator. The more side areas you have on a bird the more forgiving it will be on the knife edge side of the roller.

yes that probably explains it because ive got a small fuselage with very rear c of g. That would explain why i don't use much elevator. Has anyone been able to do a slow rolling harrier? I have tried and failed!Luke

I use every thing. With most planes I use more rudder then elevator. Lucsa Do you have G2 sim? I can send ya a video.
Happy Rolling all, Pat

I use both, more rudder mostly. I have heard of guys that just use rudder and then put in elevator it turn, but i think its harder it keep in a "harrier roll"

Yes I do have the G2. Thanks for all the help. Im kinda getting it, but it don,t look to pretty.

Any one have a video of someone doing any type of harrier i would love to see it thanks.

I will watch the TOC 2002 finals video when it gets here, Sean McMurtry does some real nice, low, in close rolling harriers into the stiff breeze. Hopefully the quality is good enough to see the control surface movements.

From what I saw on the internet, it looked like rudder only, but we will see.

Hi JoshH33
If you want videos of 3D Harriers and other 3D aerobatics heres a good sight. http://www.3dbatix.com
If you mean Realflight G2 video recordings, I could send you one.
Just let me know if you do.
Happy flying everyone:-)

THANKs for link ide like to c a g2 vid please lol

Do you guys use mixes (i.e. elevator to rudder to correct for coupling) while doing harriers?

On the simulator I can do these in my sleep. The real thing is much harder. I'm interested to see the above comments about not using too much elevator. I think that might be my problem (or one of my problems at least). I start out okay but end up in a "pop-up" where the plane's almost verticle.

I'd guess that the mixing will keep things smooth as my plane tends to pitch to the belly a little with the rudder.


Thanks........Mark

If you wanna know anything about a rolling harrier, ask Joey Hamilton.

I think I've seen him poking around RCU before.

Hi OnTheEdge

The pop-up sound like your using too much elevator and maybe too little rudder. Play with your timing then see what happens.
As for your pitch coupling with rudder, I ask of your; are you unintentionally pulsing your throttle when you move the rudder stick? That would indicate there is too much down thrust. Also makes me wonder what you are flying? few scale aerobats have pitch coupling with the rudder because engineers like myself design this out of these type of aircraft. Roll coupling is harder to get rid if without damaging other aerobatic qualities I.E. Roll coupling with the rudder is much more common. And as for Mixing, I don't use it but if your coupling is in fact aerodynamic you could mix it out or you the pilot could compensate for it.

I hope I could help you a little, Happy Flying

Thanks Pat!

Next time at the field, I will definately give the "Less elevator, more rudder" at try. After reading this thread including your advise, I'm thinking this will help a great deal.

I'm flying a 33% Aeroworks Edge. It has a little bit of coupling to the belly but no roll coupling what so ever. I'll fly a straight and level/cut throttle test to see if there is too much down thrust.

Thanks again...........Mark
