G2 Torque Rolls?
 

Can somebody explain to me how to do torque rolls in Realflight? I downloaded a recording of a torque roll, but cant figure out how to do it? Is there a way to show the movements of the transmiter while watching the recording?

Also, is this possible with a real airplane?


Thanks in advance:

Jeff

Download the 'Sudokoi' from the 'profile brotherhood' page.

This plane hovers easier than any I've seen.

Under Options>Micellaniuos>Time Multiplier reduce from 100 to about 50. Now you have time to learn the corrections needed to hover.

I figure about another couple hundred hours of practice and I'll be able to hover reliably!

Also, is this possible with a real airplane? I don't know....I doubt it.

Jeff, Go to this link and wait until it loads.
THen you will have your answer.
Remember to put the curser over the movie to start it.

idorace,

To answer your last question - YES. Charlie Hilliard first uncorked a Tork Roll in the 1972 World Aerobatic Championships and it won him the gold. A full scale TR is not the same as what we fly in RC. The full scale TR starts with a rolling vertical up-line that maintains the roll rate while airspeed is diminished. The plane will then stop on the vertical when thrust to weight is momentarily in balance and then gravity will win. The airplane starts to fall backward - like a tail slide - while continuing the roll in the same direction. The airplane slides back while rolling until the pilot stops the roll and recovers - nose down - back down the same vertical line.

Since RC airplanes can develop a 1 to 1 or greater thrust to weight ratio, we can "hang it on the prop" with proper inputs and throttle management. Fox35's recommendation for using a G2 TR recording and slowing it down is a good place to start. There are also several good articles on TR's, but here are a couple of quick tips;

1. Control surfaces on HIGH rate. This is required to get enough deflection on the pitch up - if you want to wall entry into TR. It also allows for the deflection required to keep the tail under the nose with zero airspeed and minimal air flowing over the control surfaces. You can actually fly a TR on LOW rates, but having the movement will help you if you need to bail out of the TR.

2. Little movements !!! I cannot stress this enough. If you ham fist the sticks, you will spend a lot of time chasing the airplane around the sky.

3. Throttle management. You are trying to get the plane to slide backward on the vertical line ever so slightly. You want to get the plane to slide back onto a little cushion of air and start to roll. Many of us let the plane fall back slightly and "blip" the throttle to keep the plane where we put it. The recording videos should help you understand this.

4. Keep the tail below the nose of the airplane. You have to be fairly comfortable with all attitudes of flight. The airplane is going to be rolling so know your RUDDER. Canopy up - or facing you - if the tail moves right, you would apply right rudder to move the tail back to the left. Canopy down - or away from you, and if the tail moves to your right, you need to apply LEFT rudder. If you have a working knowledge of topside rudder - as in a slow or point roll - you should be o.k. As a former Full Scale Advanced aerobatic competition pilot, I have always found it easy to think of myself in the cockpit. Contrary to popular belief, controls are NEVER reversed, they are always the same way relative to the pilot.

5. Rudder first, elevator second. Eventually this will happen at the same time, but for starters, correct YAW first then PITCH. This will help you reduce the number of times you FALL OUT of the TR. Some airplanes TR better when you set them up slightly to the canopy on the vertical line.

O.K. so these are not exactly QUICK tips, but they should keep you going in the right direction.

Good luck -

One more thing - You will notice that I never mentioned ailerons -
That's because you DON'T use them. Later on, you can use aileron to CONTROL the roll but not to create it. TORK or the proper spelling - TORQUE - is what its all about. The roll rate is controlled by good old RPM's. To much and the plane delivers more thrust than weight and the plane climbs. To little and you could be picking up sticks. Just right - Oh, the sweet spot.

I dont think anybody said this to you already idorac but a torque roll isnt something that you can just watch the stick movements on and go do it yourself. Torque rolling is all about the feel of the airplane and how to correct it. If you dont feel really comfy with flying then I wouldnt even try a torque roll b/c you are going to fail the first 500 times you try it. This isnt commenting on your piloting skills at all its just a fact of life.

1. You have to have the right plane with the right motor and the right servos help as well. I would suggest a UCD .46 with something like a .91 saito 4-stroke on the front of it.
2. Get to know your airplane very well and comfy with flying upside down, right side up, sideways (knife edge).
3. I have found the easiest way to explain the entrance to a torque roll to people is to point your aircraft straight up and let it climb.
4. Decrease the throttle to find a happy medium where the airplane is still pointed vert. but there is no forward or negative progression.
5. Use corrective stick movements to keep the airplane in this attitude. (This is the part that is a heck of a lot easier said than done). Once you are in this attitude for over 10 sec. then you have my OK to call it a hover :) Less than 10 sec. and you really never had any control over the airplane.
6. Once you really learn to hover you can find the sweet spot where the airplane TR's. It more than likely will torque roll on its own when you find this spot but you might have to start the TR with some left aileron then let the torque take it from there.

FOCUS FOCUS FOCUS and PRACTICE PRACTICE PRACTICE. I think it takes a min. of about $100 worth of glow fuel before you can actually do it half @$$ good.

Hi,

You may benefit by setting elevator and rudder to 45 percent.

Easy, keep the noise pointed up!:D

Saw Patty Wagstaff do one at the Dayton Airshow this past summer, darn near as good as Frank Knoll can with his 33% Carden , I was totally impressed !! Throttle management, elevator and rudder inputs are the key to hanging one. The easiest way is to enter it from level flight, point the nose up, back off the throttle and then use the elevator and rudder to keep it pointing up. Also use the throttle to keep airflow over the control surfaces. I found a CAP 232 3D plane on the realflight site that 3d's pretty well also the ltimate bipe there also.
