K21s are great for air experience and early handling as they are safe and easy to fly. Added bonus is they look modern and don't turn off the punter. The K13s are slightly harder to fly and spin. As such they are better for training pilots to solo level. We also own a Duo which is a delight to fly and excellent for XC and competition training. It is not as robust as the 21, much slippier with weaker brakes so harder to land, and the view from the back is not as good. If we were buying another trainer it would probably be a K21. |

I trained in the 2-33 as a teenager and now fly an ASH-26E, after three seasons, haven't crashed it.It seems to me that every aircraft flies differently a good pilot will be able to deal with these differences. My parents didn't have much money. Working at McDonald's during high school, the 2-33 was affordable. The Nimbus 3 is not a great handling aircraft but you don't hear people calling for them to be melted down. Many of us that have good jobs have forgotten what it was like to struggle to pay rent and put food on the table. I've been spending a lot of money on L13 parts to restore a glider to teach some kids in our neighborhood to soar. Sadly, that project has come to an end. Their parents are low paid federal workers and the blanik would have been an affordable trainer for their kids. Jim D |

Our club does a high volume of training and we see the same thing in
terms of Schweizer trained pilots. There is typically a steep remedial training curve to build the finesse required to fly something as docile a Grob 103. Our instructors immediately recognize the Schweitzer induced habits that have to be unlearned. When this discussion occurs the cost issue always comes up. But really, what similar sport do you know that trains with antique equipment. Golf, skiing, boating, and even regular attendance at sports events are not inexpensive… and neither is soaring. If people/ clubs really want to fly in decent equipment they become creative and find a way. My guess is that the perceived low cost of operating Schewizer equipment probably results in more people leaving the sport than the assumed high cost of operating good equipment.

he was trained in. You must be great to have around the campfire with the stories you tell... |

I will say that visiting with Bill is one of the highlights come convention time. There is no shortage of great story tellers in this sport. |

His problem was not "training in a 2-33", it was poor, improper training, or bad habit after training!!!! This "jam the skid into the ground" deal with the 2-33 is an IMPROPER LANDING TECHNIQUE......should not be taught, should not be tolerated........ A 2-33 should be landed just like any other "nose dragger glider" (G-103 II or ASK 21 etc) Landing a 2-33, on touch down, the nose should be slightly high, the tailwheel low, almost toughing the ground, and the touch down on the main wheel..........the ground roll should be with the nose up, skid off the ground, rolling on the main wheel, using wheel brake if required, until the glider is so slow that the nose comes down by itself.......stick should be way back at this point.......glider should be nearly stopped before the skid touches the ground. I see many pilots do what I call "landing in a pile".....they touch down, and immediately let the stick go forward........jamming the nose wheel (or skid) onto the ground..........some even push the stick forward!!! WRONG, WRONG, WRONG!!!!!!............ With a nose dragger glider, the nose wheel is NOT a "landing gear", it is merely for ground handling and slow taxi....SAME for the skid on a nose dragger glider.........it is not a "landing" skid, it is just to support the glider when stationary or during the very beginning of the take off roll, and the very end of the landing roll. Same for the nose wheel on a tri gear airplane........... Bad habits come easily.......in our repair shop, we have had a rash of airplane repairs where the tricycle gear airplane was landed nose wheel first.......(or bounced into a nose first landing) resulting in flatened front wheel, bent landing gear, bent firewall, and sometimes prop strike and engine rebuild.........I see "wheel barrow " landings at our field all the time......BAD TECHNIQUE!!!!! Airplanes, gliders, nose dragger, tri gear, tail dragger, all should be landed nose up, tail down. Landing loads taken by the main gear, and pitch control maintained throughout the ground roll....... So don't blame the 2-33...... Cookie |

wrote: A 2-33 should be landed just like any other "nose dragger glider" (G-103 II or ASK 21 etc) Really? The correct landing procedure for a 2-33 (and Blanik) is a recipe for high energy landings in K-21s or G-103s (or worse case, a high sink rate bounced landing leading to the infamous "galloping Grob"!). I hope you have a long runway and a big budget for brake pads! Some older gliders (and not all nose draggers) require a flown on landing - tail low, but on the main wheel - due to the tail wheel not being stressed for landing forces. Examples are the 2-33 and Blanik (note, one is a nose dragger, one a tail dragger). This is similar in concept to a wheel landing in a taildragger airplane - or a somewhat flat normal landing in a tricycle-geared airplane. The trick is that once you have established the pitch attitude for touchdown, you can't continue to increase the angle of attack to slow down or you will touch the weak tail wheel/skid too early, so some judgement and skill is required. The later generation of trainers, whether nose draggers (k-21, g-103) or tail draggers (DG-500/1000, Duo) are designed to land main and tail at the same time - minimum energy landings - the equivalent of a 3- point landing in a taildragger airplane. This is also the way almost all current single seat gliders are designed to be landed, for obvious reasons - gliders are now heavier and land faster, and need to be landed at the slowest possible speed in an off-field landing. That is one of the reasons the 2-33 is a poor trainer for today's glider pilots (assuming they intend to move on to something more interesting than a 1-26). If all training is done in a 2-33 (or Blanik, to be fair), then a careful checkout in a modern glider is essential to properly prepare the transitioning pilot for the landing characteristics of most modern gliders. Just to keep this discussion interesting, we can now argue whether a low energy tailwheel-first landing is OK or bad for a modern glider (assuming a reasonable sink rate at touchdown)... Kirk |

Cookie On one of my wife's 2-33 instruction flights: The instructor wanted to land and stop quickly so he would not have to push the glider too far back to the takeoff point. He jammed the skid onto the paved runway at touchdown. The friction heated the metal skid to incandescence and caught the wooden skid underneath on fire! |

I notice that 3 or 4 of the USA World Team members trained in Schweizers. A large fraction of 2-33's already have patches on their wings due to metal fatigue cracks. I've found cracks on several the AI missed. Look at the skins on top of the wing ahead of the spar. If there are skin cracks, there's a good chance of other cracks where they can't be seen. There will be an AD - probably sooner than later. As to why there are no SB's - ask Schweizer. |
