I throw in some random thoughts. Waynes advice is some of the best you will find, read it over a bunch of times!

Here we go...This is what is going through my mind...

If the airplane does not start turning to the left in a hover, you are not completely vertical.

If it starts spinning really really fast you are definitely vertical and probably falling backwards a little bit. Expect a qucik spin rate from that YS .63, it's got A LOT of torque! Using a 13x6 instead of that 14x4W will slow it down just a little.

Perfect vertical WILL be slightly on it's back.

Perfect vertical will still have the airplane slightly on it's back, even when it's back is towards you!

Don't over correct. Make quick, but smooth inputs.

Knowing how your airplane reacts to each and every one of your movements is more important than knowing which movement to use.

Ignore your ailerons! Forget about them. They don't exist. No more ailerons!!

The throttle is just as important as the other two controls, don't ignore it. Knowing where it should be for your airplane to hover is just as important as knowing what your airplane looks like in a perfect vertical position.

You WILL NEED to move the throttle stick. Some people like pumping or "punching" the throttle which will really get the airplane torque rolling. It also gives your control surfaces some more authority when you kick in the throttle. It makes it harder for learning.

Find out what throttle setting it will hover at. While hovering, stay within 2 clicks of that position. If you ever need more than that to pull it back up, it might be a better idea to fly out and try it again. This will be best for learning.

Up elevator and right rudder are the most common inputs. You will need to just barely touch the elevator stick to hold it vertical most of the time. Constant back pressure makes it sound like it needs a lot, but it needs VERY little.

Keep your rudder and elevator throws down so you don't overcorrect or get into some weird spins trying to recover.

Once you've found the perfect vertical position, let go of the sticks. If the airplane really pulls down or really pulls to a certain direction everytime, change your engine thrust to compensate. It makes a world of difference!

Move your CG back as far as you can, but just go about 1/4 of an inch at a time.

Wind makes it much harder! On a windy day the airplane will automatically try and pitch itself into the wind, which makes it really hard to torque roll. It takes bigger and quicker inputs to really hold it vertical in the wind, not as fun either. Once you get good, you might enjoy it though...

NEVER and I mean NEVER EVER look at the tail in a hover. NEVER! Do not look right at the nose either. Look RIGHT AT THE CANOPY or where the canopy would be. Right in front of the wing is what you should be watching. The canopy! This will REALLY HELP to prevent over correcting or chasing it around in a hover. Watch that canopy!!!!!

If the airplane's back is towards you, tap the rudder stick in the direction of the LOW WING.

When you fall out of a hover, let it pick up some airspeed before pulling out and be gentle! Don't yank it up if you've got the space to let it get up some speed.

That's all I can think of for now, aren't ya glad? :P
