Practice 4-point rolls until you're blue in the face. A single complete revolution first, then string two together, then continuous 4-point rolling, right to left pass in front of you, then left to right...

Eventually you'll find that the stick movements for 4-point rolls are starting to flow together into a continuous repeatable motion, and that's the start of your rolling circles. Rolling harriers are just a slightly harder variant.

Don't get discouraged either. It takes months of dedicated practice for most people - years in some cases if practicing often is not an option. I'd guess somewhere between 100 and 200 packs for that initial "hey, that was almost an ugly but sustained rolling circle, sorta, kinda, if you squint" feeling, and that much again for something resembling proficiency.

Low rates can help, especially on fast-rolling planes like this one, and especially when you're starting.

It's all about practice and effort invested. That's what makes 3D so rewarding

Kamikazi Pilot. What expo rates are you using with those rates?

I have been flying with all rates at 80% with 30% expo.

I used to use around 75% expo on everything. It will smooth things up. I now use around 50% expo on ele/rud and 25% or so on ail. I have dual rates, full on one switch and then reduced aileron for the lower rate (ele/rud stay 100%) - to learn rollers, I was visiting someone in hospital over an extendend period one time, and ended up with a lot of spare time. One day, I spent a whole day getting the rollers down on the sim and that did it.

Great video's Rick.

I found the hardest bit to getting rolling circles was the last quarter when it starts coming back at you. Like H2SO4 said getting the stick inputs and timing down for four point rolls then smoothing them out and linking them together together to get consecutive rolls in a straight line line is the first part. Then to bend it round the circuit you have to bring the timing forward for an outward rolling circle or delay it for an inward rolling circle. I did the same as Rick too with ailerons set on very low rates but rudder and elevator on high rates. I don't use it much now as it can stop the roll when you get very high alfa on rolling harriers but to start off with it was handy to just jam the aileron stick hard over and just concentrate on your rudder elevator inputs.

It takes very little input to do rolling circles with these planes.

On both the sim and model I have 60 on full and 20 on low rates. As the other guys already mentioned it takes quite a bit to get good at. I went the tougher route and started doing the harder stuff instead. What can I say, I like a challenge.

I started learning rolling circles by doing the only thing I knew how to keep it going. I started doing them using the rudder only, no elevator. That way I was only thinking about 1 input. They looked a little clunky obviously but you could call it a rolling circle. Then after I was comfortable with what my left thumb was doing I started adding the elevator where needed to smooth it out. May not work for all but that's how it learned it. I haven't mastered going both directions yet but getting there.

Ive been practising for 6 months and lots of stick time, I still havent got a clue.
Only 14 year olds can get it in a coupla months, us oldies dont have a chance of a quick learning curve, itll take years i reckon.

Had to replace the rudder servo. Very calm weather here today flew 8 batteries only bonked her twice.

Just got some blue thera band delivered for prop savers.

Boy this plane is fun to fly!

Hey Tbone I'm pretty sure most guys have 45 degrees of throw on the Yak. As to high and low rates depends on the flyer.
On mine I have it set at.
High 100%
Low
Ailerons 50%
Elevator and rudder at 75%
Expo
High +60
Low +25

Good luck on your build.

Just flew 4 batteries, great weather here. The more I fly the CY the more I love this plane!

On 3rd flight the thera band prop saver let go and the prop went sailing off into the blue!

Was able to land it with no problem and found the prop put it back on and finished the battery.

Charging some batteries for the SBach.
