Thank you for all of that info. That's a reason why I wanted to learn about using rudder, scale flight, altitude conservation and just to see how it works. I was also wondering about slips and stuff in sims so you clarified that for me.Many planes, especially beginner RC planes can be flown without using rudder. That said, understanding rudder and using it will make you a better pilot; opening up new options like flying knife edge; making flat turns in gliders to conserve altitude; flying scale aircraft, especially WW I and II vintage; side-slipping to lose altitude quickly for small landing areas; and landing in strong crosswinds.
About tip-stalls: most people use the term incorrectly. Most people use the term "tip-stall" to refer to an aircraft's tendency to drop a wingtip when it stalls. This is just a stall. Many aircraft will drop a wingtip when they stall. In a properly designed wing the root of the wing will stall first and the stalled portion moves out toward the wingtip as the plane slows. Usually the wing will stop generating enough lift to hold the aircraft up before the stall propagates all the way to the tip. If you can keep the wingtips generating lift even at high angles of attack the aircraft will stay controllable throughout the stall and recover relatively easily.
In contrast, a tip stall is when the wing tip stalls before the root of the wing, making for violent and unpredictable stall behavior. If your airplane is tip stalling, it is a flaw in the design. Many FT planes have under-cambered wingtips because under-cambered airfoils stall at a higher angle of attack than flat-bottomed airfoils; this keeps the wingtips generating lift and control even when the rest of the wing has stalled.
Flight simulators generally do a bad job of simulating stall behavior. Stalls are usually very docile in flight sims. Accelerated stalls, such as when you pull sharply out of a dive, are rarely simulated. Flight sims also do a bad job simulating side-slips and forward slips, but that's not what you were asking about.
Thank you for the video. Very helpful.To combat adverse yaw, no. Check out this video on it to better understand adverse yaw:
There are some situations in which you would use opposite rudder compared to the ailerons, but they are usually more special things like knife edge or slipping.
Thanks, I had always wondered about that. All of these aeronautical concepts that I had always heard mentioned but didn't understand. In the few days I've been practicing with rudder in my turns I've gotten pretty used to it.I always coordinate turns. It becomes instinctive.
Rudder is an invaluable control surface on any aircraft, from an Airbus A380, to a tiny 4 channel R/C plane. While most airliners can fly “feet flat on the floor” because flight computers coordinate turns for you - but on landing rudders are always used. Likewise, with any single engine propeller aircraft (any size) - P-factor in a climb induces “left turn” tendency requiring right rudder on every climb.
One more unrelated question. This might take a while to answer. You know how commercial pilots land main wheels first and then slowly put the nose down? I have been trying to practice landings like that but I find it very difficult and I need to set up a golden glide slope. Is it supposed to be that difficult? What's the best way to approach it. Again, its only for commercial pilots to make the flight smoother. I have no problem with my typical landing style where I cut the throttle and sort of hope for the best. I have learned to manage my throttle better in general which has helped my landings a lot. Back then I would just either go full throttle or cut it...
