BoneDoc's 3D Clinic #1: Upright AND INVERTED Harrier - NEW SECTION & VIDEO ADDED
I knew that there are plenty of people who would like to see instructional videos complete with stick movements. I've been contemplating the idea for a while now, and with the help of my lovely wife, Inn, I was able to pull this one off. I'm by no means the best 3D pilot out there, but I hope this can be a spring board for further discussion and will help lessen the learning curve for the newbies who are venturing into 3D.
Without further interruptions, let's dive into the first topic of this clinic: Upright Harrier. I believe that this is the fundamental skill in learning 3D, and it's one that teaches pilot how an aircraft behaves in post-stall attitude.
First, start learning upright harrier by learning how to do an elevator. Once that is mastered, then add more throttle until you're no longer sinking and are now in full-on upright harrier. Don't worry about "driving" the plane first, but learn how to correct for wind / wing rock. Once you're more comfortable with that, then work on trying to drive the plane around. In other words, make the plane go where you want it to go. Concurrently, you can also start learning how to bring the plane closer and lower. Finally, we'll end this clinic with harrier landings.
This is by no means all inclusive, but I hope it gets the ball rolling for you in your 3D Journey. Hopefully this will be the first of many.

A question arose about my radio setup, and here's what I use:
Ailerons 45 degrees with 45% Expo
Elevator 50 degrees with 60% Expo
Rudder 50 degrees with 70% Expo
Ailerons 25 degrees with 30% Expo (almost never used)
Elevator 25 degrees with 30% Expo
Rudder 50 degrees with 70% Expo
A recommendation made by 3DH on their aircrafts
Low/Precision Rates (in degrees and inches) and Corresponding Exponential
Aileron 15 degrees 30% Expo
Elevator 13 degrees 30% Expo
Rudder 45 degrees 75% Expo
High/3D Rates (in degrees and inches) and Corresponding Exponential
Aileron 28 degrees 75% Expo
Elevator 45 degrees 85% Expo
Rudder 45 degrees 75% Expo
I tend to use lower less expo than what the consensus. I compensate for that by making smaller movements. The only time I really use lo rate ailerons is if I'm trying to make precision rolling circles. Otherwise, the elevator is the only thing I switch back and forth.
There's no real "right" / "wrong" answer about this. With the aileron high rates on at all time, it allows me to make cleaner and faster snaps, which helps a lot when I'm doing my KE to KE snaps. The less expo on ailerons also allows me to make my corrections early when the plane rocks from the wind gusts. The down side is that if you're not used to it, you can potentially over corrects. I tried the same setup on Doc Austin's SR, and from the brief flights he's had on it, he liked it as well.

Excellent video Bonedoc - already itching to get out and give this one a go.
Really like the idea and the way you have presented the video.
The forums have been crying out for a resource like this - I've seen animations/simulations, but you can't beat the real thing.
Please keep it going!

What a great teaching video. This is just what I have needed. I am looking forward to future teaching videos.
I have already been out this morning with my D W Foamy 39" Yak and P A Addiction to practice the upright harrier.

Great! I'm glad that you guys have found it useful.
It's been a learning tool for myself as well. For one, I just learned, that the way I turn is slightly more aileron dependent than what I've heard others do. It looks that I just feed a touch of rudder, then use the aileron to bank the plane the way I want it to go.
Naturally, you'll need to hold a bit of right aileron to counter the torque of the propeller, so when I was turning left, I was using a small amount of left rudder, then periodically let go of the right aileron to get the plane to bank to the left a bit.
Others will just add more rudder until the plane starts banking. Just another way to "skin the cat."

There should be an explanation in the video. Sorry for the long download, but it helps keep the quality of the video high enough that people won't have to guess what I'm doing.
1) Get to a safe altitude
2) Yank back on the elevator
3) Feed a touch of throttle to pick up the nose a bit
4) Recover (usually downwind) by adding more throttle and easing up on the elevator
... That's it! .
Once you want to get fancier, you can start driving it around with your rudder and ailerons.

Good morning Josh and thanks for the video. Hoping that more are to come. Question for you? Is that a battery tray that you use? Any info on it? I've been considering one and need some tips, ideas, etc..

Wow..... Josh, that's a great way to teach! I now can begin to learn the skills you have perfected through the years.
Going to need a lot of practice and hopefully the ground does not "come up" and grab the plane.
Keep it coming as I am sure most of us 3D junkies are looking forward to more.
Thanks for your efforts....and I am sure your precious time.

Awesome Josh!! Thanks so much. This is like having a private instructor. And thanks to your wife for doing such a great job on the video.

Also as you guys are practicing these maneuvers, I'd appreciate feedback also. We're all learning together after all .
