Humbled and Learning (Slowly)
Recently I bought a 1974 Helio Courier H295, which is a six place STOL
taildragger. Prior to last week I had never flown a tailwheel airplane. Wow, this it hard! The Helio is designed for one purpose: to take off and land very short. Everything is compromised to accomplish this. The main gear is at the firewall so that you can land with the brakes on hard and not nose over. The cg is much farther behind the mains than normal on a taildragger. Because it is a six place, the tail is waaaay back there and the wind has a lot of leverage to weathervane the airplane. It also has 295hp so the left turning tendancy under power is pretty strong. Today I was doing great with several good (though not great) landings and takeoffs where I was maintaining the centerline with a 7kt crosswind from the right. Then we did power-off approaches landing the opposite direction (crosswind from left). What a difference on takeoff! Even with full left rudder I took the airplane off-roading into the weeds! There is a huge difference between a left and right crosswind on takeoff. Then off to a small airpark where we landed on a grass runway and came to a stop in under 300'. The last landing was back at the airport and wasn't very good. The airplane has tremendous performance, but it is going to take quite a while before I can effectively use it.

Learning new skills, are you? :-) Was there anything in the way of a manual that came with your aircraft? What do you know of the history? Was it really built by Helio? Was it used in SE Asia? Did you use aileron into the wind on takeoff and landing? Are you trying to hold the centerline, or are you cheating into the wind on a diagonal to reduce the crosswind component? When you use the rudder pedals, are you sliding your feet with your heels on the floor or are your feet up off the floor on the rudder pedals? Have you looked at the airspeed indicator at touchdown? What is the indicated airspeed? Questions, questions, questions... |

Recently I bought a 1974 Helio Courier H295, which is a six place STOL
taildragger. Prior to last week I had never flown a tailwheel airplane. Wow, this it hard! Back in '75, I heard so much about how hard it is to converse from tricicle to tailwheel that I decided to do the remainder of my PPL training on tailwheel aircraft and "learn to land properly" from the first. It must be a lot harder if you have a lot of experience to unlearn. Congratulations on your purchase! The Helio Courier is a remarkable aircraft. You're right that it is a champion STOL machine and slow flyer; those huge double-slotted Fowler flaps bring it right down to twenty knots or so, and with a little wind you can easily fly backwards, so beware of making any rash downwind turns. I don't agree with you that everything is compromised to get the STOL performance. The Helio has a huge envelope and it flies well at any speed. It is sleek and glides very well. It's versatile. The big engine (the Helio that I flew had 260hp and was a 5-6 seater) has quite some torque and it's true that you almost need a ladder to climb into the front, and taxiing is a bit of a drag for a small person like me, and the coffee grinder takes a lot of turns before those flaps are where you want them (does yours have a different flap operating system?), but those are minor inconveniences IMO to get so much in return. You're going to love this plane! BTW, the one that I flew had a curious gadget called "crosswind landing gear", with which the wheels could be turned up to 20 degrees to either side off the centerline of the plane. It's simple in theory but it always scared me -- what if the mechanism fails on one of the wheels and you were stuck with converging or diverging wheels! -- but the owner liked it. Once I flew with him into Ostend (Belgium) and we were offered the use of the large empty platform instead of the runway because of the strong crosswind, and he replied "Negative, we have crosswind landing gear". I'm sure that they had never heard about it or didn't understand what he meant. He continued on final for the runway and landed. It's quite strange when you're in the plane and it starts rolling sideways, but to ATC it must have appeared like a crash. When the plane continued for the runway they had already dispatched the fire trucks and when we rolled out they were driving along with us and firemen were jumping out to grab a hold of the wings (which is rather difficult because they are high and the plane has no struts). It was like a scene out of a Keystone Cops movie. It took a while to convince them there was nothing wrong with the plane. I then discovered the big disadvantage of the crosswind landing system: once the aircraft's weight is on the wheels, they won't rotate back to the neutral position without the help of a lot of people to lift the plane. X-wind systems seems to be an anomaly; I've never seen any used before or since. It would make the Helio's extremely short landing roll even shorter, but it's so short already that you can land almost anywhere at a pinch -- a short taxiway intersection, for example. My friend said that he could land on a postage stamp and I believe he could manage very well with a garden. He used the plane for aerial photography and said it was ideal because it could fly slowly and had no struts to get in the way of a good picture. Helio Couriers are very rare in Europe and it was difficult for him to find spare parts. Perhaps parts and planes are more plentiful in the USA, but it's still an unusual aircraft. No matter what your mission is, you're sure to find that the Helio can do even more than you thought, and far from any reasons to buy it you'll have more reasons to keep it. Have fun!! Effie. |

Mike,
Take it from a fellow low time tailwheeler - you'll get it! Everyone seems to overcorrect with the rudder at first. I've never flown a Helio but I've read a fair amount about them and seen videos of their amazing performance. AOPA had an article about the Helios in the January 2001 issue. What a fantasic airplane. They even made a tricycle version. Good luck Dave 68 7ECA Mike Rapoport wrote: Recently I bought a 1974 Helio Courier H295, which is a six place STOL taildragger.

"john smith" wrote in message ... Was there anything in the way of a manual that came with your aircraft? The usual. What do you know of the history? Some probably no all. Was it really built by Helio? Yes Was it used in SE Asia? No Did you use aileron into the wind on takeoff and landing? I'm not certain. Are you trying to hold the centerline, or are you cheating into the wind on a diagonal to reduce the crosswind component? I have been trying to hold centerline. I realize that, by diagonalling, the cross wind component can be reduced, but I don't feel that I would be developing skills. When you use the rudder pedals, are you sliding your feet with your heels on the floor or are your feet up off the floor on the rudder pedals? Even with the rudder pedals in the furthest position (they are adjustable), I can barely bend my ankle enough to land without the brakes on so I have been using the balls of my feet on the lower part of the pedals. I am getting and using full rudder. Have you looked at the airspeed indicator at touchdown? What is the indicated airspeed? Actually I have been pretty busy at touchdown! I can tell you that it is a lot slower than the MU-2 at touchdown! Mike MU-2 Helio Courier |

You're going to love this plane! Fortunately mine has electric flaps and the control is located so you can bring the flaps up or down without taking your hand off the throttle. The pitch trim is electric too. Mike |
