Make the plane point toward the sky without moving. Then all you have to do is hold it there..... :)

Good luck!!

Maybe tie you plane to a helicopter....

100$ worth of fuel

Get a straight upline, reduce throttle until stopped, apply throttle to maintain altitude and try to balace the plane like you would a baseball bat on your hand.

Do u want to hover or torque roll?

In either case, make sure your radio is set on high rates if you have dual rates (except ailerons for a torque roll - some guys use aileron to assist in a constant roll rate, but this is not an actual torque roll).

Mount enough power on the firewall to swing a large-diameter prop giving the most thrust. Also set the CG a little aft of the recommended.

Pull the aircraft to the vertical while slowing it down. Practice vertical lines until you have them clean. If you are not using gyros or mixing on a computer radio, make sure you add in some rudder on the initial pull because the aircraft nose will tend to walk on the pull.

Let the aircraft slow until it falls back slightly - this is the "zone". The aircraft has to be in a complete vertical with the tail under the nose.

At this point, torque will take over and start to roll the aircraft in a R/C modeler "torque roll". The full scale Torque Roll is a rolling vertical with a controlled, maintained roll-rate as the aircraft moves back down (backward) on the vertical line. For our purpose, ailerons will do you no good. Control the vertical with elevator and rudder. Keep the tail under the nose. This requires small movements of each surface, but you will need high rates in case the tail wanders a lot. To get used to the control inputs, move one input at a time (rudder, elevator). The torquing is accomplished by the engine torque and the rate can be controlled by altitude (power). If the aircraft is rolling slow, reduce throttle and let it settle through the prop-wash a little more. To slow things down, add power and climb slightly.

To hover, entry is the same but rudder and elevator movements are more exaggerated to suspend the roll. As I stated earlier, ailerons are pretty ineffective at this point because of the low or non-existant forward speed. However, you can burp the throttle to achieve some aileron effectiveness in both maneuvers.

And as jnjacksn said:

RUDDER!
 
Lots and lots of RUDDER.

If you can't fly with Rudder you'll never get it.
Get that left stick wiggling!

oh ya...
And lots of practice!!

High Flights.

Lots of control throw and lots of gas.

Did any1 say PRACTICE PRACTICE PRACTICE (: Realflight G2 also helps

Shortman if you learned with a hundred bucks of fuel you are good or you know where to get fuel for about 4 bucks a gallon

Hover
 
Kule mentions some good tips. I'd like to add to that.

For hovers, I lean the nose of the plane in to the wind about 5 degrees. This helps stop the natural TR. I have found that on most planes (fun fly types are the exception) that there isn't enough aileron to stop the TR unless the wing is flying a little.

For TR, one tip I'd like to add is that you can greatly increase the authority of a control surface (elev/rud) by giving a blip of power. Most of the time this is not needed, but if you encounter a gust of wind that blows the tail out, adding a blip of power will help increase control.

One word of caution... If you slide backwards into your propwash (you will typically hear a buzzing sound) you will need a lot of power to stop the fall. After adding power, when the prop finally catches again and stops the fall a lot of torque is transfered into the plane. This will give you one heck of a fast TR. This has happened to me a few times on my 35%. It will go from a 2 second TR to a 2 per second TR real fast. First time that happened to me low to the ground I needed to check my shorts.

Well I think that just about covers it. :^)

Thanks for the info on the realfast tr. I was wondering why it did it.also if you add power to fast it will do the same thing.
