BoneDoc's 3D Clinic #3: All About the Knife Edge


Hey Gang,

Thanks to all who've posted their feedback as well as encouragements on the last two clinics.

BoneDoc's 3D Clinic #1: Harriers, Upright and Inverted

BoneDoc's 3D Clinic #2: KE Spins & Blenders


On to the next clinic topic: "All About the Knife Edge"

The Knife Edge is definitely one of my favorite maneuvers. It's usually one of my fall back maneuver when I don't want to just fly straight and level across the sky.

To start, just set yourself in the proper mindset for proper rudder input.

Think: "OPPOSITE RUDDER"

That's how you get yourself thinking the proper rudder input when entering KE from an upright flight. Once you're there, it's all about maintaining KE, which is easier if your model has little pitch and roll coupling to start with.

Neil also added a good tip on getting the correct rudder heading.

Thanks again for doing these videos, Josh. They are great!

Another tip is to MAINTAIN SPEED. This will make the rudder more effective, and lessen the rudder input (which will lessen the coupling on most models).

I also CHEAT INVERTED (See Video #3a). That will help you bail out properly. By cheating slightly inverted, when you're in trouble, just push the stick (down), and that will move the model AWAY from YOU and the GROUND.

Finally, PRESENT THE TOP OF THE MODEL TO THE PEANUT GALLERY. That's good etiquette, and it looks better to boot .

On the 2nd Video, I also discuss more advanced Knife Edge flight, such as entry, KE snaps, KE figure 8's, KE loop, as well as previewing the upcoming clinics.

Hope you enjoy them. Please post feedback for improvements as well.

Yours Truly,

Josh "BoneDoc" Young

Special Thanks to:

Great video - Again! Another appreciated - perhaps intentional, perhaps not, feature is that we're basically watching unedited runs - i.e. if you blow a KE loop - we see it. Thanks for showing us the reality.

Don't want the thread to turn into a debate on this but I'm still liking the overlay best.

Now I've gotta get back from vacation to crack off the rust!

Awesome, Awesome, Awesome. , Thanks to you and your wife for doing these. I really need to get someone to shoot video of my flying so you guys can evaluate it and tell me what I am doing right and wrong. I have been practicing the knife edge loops, They frighten me

Thanks guys,

Scott... they STILL frighten me, especially on post call days when I'm sleepy and not on my game .

I'd say that once you can do the last 1/4 from the hammer head, start with a long downline, and curve it into a KE.

Very good tip! I started using the opposite mind set, then said "come on, just put yourself in the pilots seat and get orientated!" that has been hard as well. The rudder to the nose is PERFECT! can't wait to try.

Downloading now. Looking forward to this one!

Thanks!

Funny what bothers us, The knife edge loop for me ( with a well trimed plane) is simple

I do the knife edge snaps but the one and a half snap to the other side is beyond me, jjust starting to work with the half roll on the knife edge eights.

The one that really puts the pucker in it for me is a rolling loop, that last full roll at 3 oclock just tightens things up.

Still need more practice with the left thumb, rolling harrior's with out enough rudder input.

I like the looks of the "Slick", great tumbler, and looks to be an honest flyer. Not all models will do what it does.
