I fall in line that the way controls work in mode 2 is for the primary roll control to be on the right stick. With a 4-channel plane that's aileron. With a 3-channel plane that's rudder. But roll control is roll control and the plane absolutely does not care from which control surface it comes. To prove it, an experiment is in order. Take a Super Cub, modified with ailerons. Hook it up three channel, aileron, elevator throttle and fly it around. Land and hook her up rudder (right stick), elevator throttle. It will fly so close to identical in both configurations you'll be horrified. Primary roll control on the right stick. It's the right way to go. Yes, assignment of sticks is arbitrary. But let's get real here. |

Sometimes I don't even give them any instructions beyond "This is throttle up, and pull back here to take off". Then I leave the room and go make lunch. By the time the soup is done I can hear less and less crashing coming from the computer's speakers. I come in now and then to encourage them. One of the best things to do with a beginner is to put them right in the cockpit with "cockpit view", especially if they are having a hard time. It is easier to fly from the cockpit, and it is the simplest way to give the student an idea of how the control sticks move the plane (bank and pull back slightly). When they get good at that, I switch them to 3rd person perspective and they get the hang of flying quicker. Only after I see some basic ability (usually an hour or two), do I then take them to the flying field and hook them up to the box to fly a real rc plane. By the time they are in the air with a real plane they can do fairly well. I might rescue them 10-15 times during their first flight, which is about average depending on their ability (and IQ, I think).

I would not be surprised at all at the results of the experiment above. The two riggings would have nearly identical behaviours. When I first voiced my opinion on this matter, I said: Quote:
When you fly a helicopter, the primary direction control (heading control) is your rudder, or tail rotor. It is essential to learn how to turn a heli with rudder in order to advance to more difficult concepts, like cyclic control (aka elevator or aileron). That is why beginner helicopters have only rudder control, no real cyclic (although they imitate some cyclic by using a horizontal tail rotor, which causes the heli to pitch forward or backward, which in turn causes it to move fore or aft). For helicopters, a rudder deflection results in a pure spin about the z-axis, and only that, whereas an aileron deflection results in a pure roll about the y-axis. So, if a person transitioning from 3-ch to 4-ch (with the tail rotor control suddenly swapped) attempts to spin to the left, he finds himself immediately ROLLING to the left instead! Case in point, and MY EXPERIMENT (which I already did, btw): I can do some pretty good aerobatics with my Blade 450 X flybarless heli, after a year or so of flying helis. However, the other day one of my nephews asked me to fix their 3-channel coaxial toy heli. I fixed it with a new battery and tried to fly it, and ended up crashing it all over the place at first! Why? Because the stupid tail rotor didn't yaw the helicopter, and the cyclic controls spun it around instead of banking! It was like riding a bike backwards all of a sudden! I almost broke the left stick trying to put some tail rotor control in! So, I will agree that learning 3-ch plane flying is fine if the rudder control is on the right. ![]() For helicopters, however, I stand my ground! All 3-ch helicopters should have rudder on the left!

Glassdogangle I just asked to verify that in the end your students do get the instruction that they need. The "yes" was good enough, but your explanation was great, and I like the other things that you do as well (simulator and soup, etc.) For the record we don't ground handle IN the pits either, but outside the fence is rolling territory.
I have to say that the forum is making a much bigger deal out of the 3 ch. situation than even remotely necessary. If I had a student that took as long to "get it" as some people are spending describing the impending doom, then I would highly encourage them to work harder at other aspects of the hobby. Spectating maybe? It is just very difficult to believe that a person could overcome the other obstacles to becoming a pilot, orientation, wind, approaches, etc. but then struggle with this little detail to the point of failure. I have said it before and I will repeat it now, 3 ch. helis are a completely different situation! I can only imagine that the manufacturers of those don't want their toys to look too "cheap" by only having one stick. Maybe? |

All right! We're all on the same page.
Now, thanks and a tip of the hat to Bert Lahr All together now! ![]() Quote:

For helicopters, I agree, rudder should be on the left stick always... but for planes it really depends on what kind of plane it is. |

Ha ha ha, it's all good. And to think I got on here originally to tell everyone (brag to everyone) that the new photo field "Douglas Lake" in RealFlight 6 is actually a spot on the Willamette River in Albany Oregon, where I live! It is located just north of the Bryant's Park softball fields!
When I first saw the photo field in RealFlight 6, I immediately thought it was Bryant's Park, but then my reason overruled my intuition (of course it's not Bryant's Park, when was the last time anyone ever took notice of little old Albany, OR?) Another thing that threw me is that RF 6 has a fake 3D model of a dock right on the edge of the river, but in real life there is no dock. Well, I flew my heli there for the first time ever yesterday. Then, later that night when I fired up RF 6, I just happened to load "Douglas Lake" at random, and then it hit me! I was like, Oh my gawd, I just flew there right at that spot! I did a quick google search on "douglas lake bryant park willamette river" and other such terms, but i found nothing. Since I have never seen anyone fly out of this spot before (it is DEFINITELY not a well know area for flying), I guess I felt kinda special knowing that the guys at RealFlight would take special interest in this little spot on the river, and make it a background for one of their photo fields! It really is a fun place to fly in real life...

As I mentioned a lot earlier in this 'thread', (more like a ball of tangled wool
), when I learned to fly RC it was rudder only, there were no computers for a flight sim, no buddy box. Yet strangely many many of us old foggies learned to fly model planes.Going by the advancements in technology, beginner should by now be able to fly a model in about 5 minutes. ![]() I wonder why they can't

One word elfight, FEAR. So many newbs are terrified that they are gonna crash, it causes them to..............crash. My cousin is a perfect example. A friend built him a GWS Slow Stick and he spen around $200.00 for the whole RTF package. He has flown it once with the builder. The builder took the plane off the ground, got about 2 mistakes high, handed the TX to my cousing who, after about a minute, promptly handed the TX back to the builder. He's basically scared to fly the plane.

But we weren't afraid of our planes because they already demonstrated they could fly themselves. We hand launched our planes and trimmed them to death until we were satisfied. We had lots of experience with power so we knew what to expect there. Heck powered free flight planes were old hat. Here we were with a plane that if the radio failed the worst that could happen was a landing somewhere we didn't really want, perhaps an uncomfortable distance away. We figured our fuel load accordingly. Then we launched, diddled with the rudder when necessary and were amazed that finally we could guide our plane to land generally where we wanted to land instead of having to chase the thing. What if people today were to start with one of the old free flight airplanes with a 3 or 4 channel radio? It would be a no-brainer if....... because shortcuts make the job harder. Trim and setup are major parts of what gets accepted as flying skill. Without free flight experience, modelers today learn by trial and terror. |
