STEP UP SAILPLANES FOR SPORT OR CONTEST FLYING
Many new sailplane/glider pilots start with 2 meter foam or wood R/E gliders. If you are one of these and have found you love thermal soaring, and who wouldn't, you may be wondering what your next step up plane might be. This is written for you.
I am going to bring a few to your attention. These will traverse a wind range of wing spans, materials, control surface choices as well as kits and ARFs and a big spread on prices. There are no RTF planes in this discussion. I only include planes that can be purchased new.
You can always look at used planes, but since their quality and availability are not reliable, that is not the subject of this discussion. There are always deals available on used planes, if you can find one. Just make sure you know what you are buying.
I group the planes according to common contest wing span sizes.
Up to 2.0 M Up to 2.5 M/100" - also called standard class Any size, but typically over 2.5M, is the unlimited class.
I have the various materials and control surfaces mixed together but I do mention what they are. I set a price limit of $500 for the 2M planes. Larger planes are capped at $850 in this arbitrarily "midrange" class of planes. This is the cost for the kit or ARF alone. This does not include electronics or accessories. However there are planes on the list for under $200, so there is something for everyone.
Note: Prices are for reference only as they can change at any time.
If you have the budget, the leading contest planes, like the Sharon, the Pikes, the Supra, the Icon, and others, typically run over $1000 and some can run 0ver $2000. They are not mentioned here.
If you have recommendations for planes that are available NEW, please feel free to post your recommendation, a link to the source of the plane, and why you recommend it.
Naturally what represents a step-up plane for you depends on what you are flying now. So I am going to assume you have a 2M Easy Glider, Spirit, Gentle Lady, Vista or some other 2 or 3 channel glider that is normally recommended for beginners.

OTHER POINTS OF CONSIDERATION
Bigger Flies Better
There is a saying in the sailplane field that bigger planes fly better. New pilots are usually started on 2M planes because they are typically lower in cost, easier to handle on the ground and less intimidating than larger planes. Also they are easy to transport. And, there are even some RTF or receiver ready 2M planes making it easier for the new flyer to get started.
And let's not forget that they are fun to fly!
However, like a small boat vs. a large boat, the larger planes tend to fly better across a wider range of conditions. In addition, if you plan to range out from the field in search of lift, or to continue to work the lift you have, a larger plane is easier to see farther away. So, there can be many good reasons to consider larger wing span planes.
On the other hand, you have to store and transport your plane. Will the wings fit in you car? Do you plan to travel by plane with this model? How will you transport it?
My largest winged sailplane has a wing span of 3.4 meters and a 2 piece wing. So each wing half is about 5.5 feet long. They "just fit" in my car with the back seat knocked down and the wings going from the back of my trunk to the back of the passenger seat.
However I have a second 3.4M plane that has a 3 piece wing. This is much easier to store and transport. So take wing design into consideration.
A 2M plane can call for a one piece wing that will be about 6.5 feet long. Others are based on two piece wings. Again, take this into consideration for storage and transport.
Sport or Contest?
If you are flying strictly for the joy of soaring, then make your choice for your next plane according to your desires. However if you have gotten a taste of contest flying and you love it, this will influence your next choice.
TD contests are usually broken down into 2 M, Standard Class which is up to 100 inches or about 2.5 meters. Then there is unlimited which includes all wing spans,but mostly involves planes with 3M wing spans and above. Note that most unlimited contests don't mind if you enter a smaller plane. I have flown a 2M Spirit in an unlimited contest. I didn't win, but it was fun just the same.
Control Surfaces
Then there are the control surface competition classes. Typically there is RES and all other. RES contests are restricted to planes with rudder and elevator controls with spoilers optional. Some RES classes may allow flaps, but check first. Usually, if a contest is not specifically RES, then you can fly whatever controls you like.
Some people mistakenly think of RES sailplanes as beginner planes. And, while it is true that they are typically lower cost and easier to fly, there are high end competition RES planes that stand up very well against the high end full house competition planes. The flying style is different but you can launch 'em high, stay up a long time and land with a fair degree of precision. So don't assume that RES planes are not competitive with full house planes. The pilot is the difference.
Radio Considertion
One advantage of RES is that you can use a simpler radio system as only three channels are needed. A standard 3 channel radio can fly the plane. However you will still be better served with at least an entry level computer radio that has elevator compensation for the spoiler. It may be listed as flap to elevator compensation in the manual but it can be used with the spoiler.
Planes with ailerons or ailerons and flaps will require at least a 4 channel standard radio and typically you will want a 6+ channel midrange or 8 channel advanced computer radio to take advantage of the plane's ability to change the shape of the wing by moving the flaps and ailerons to new positions during flight. If you go R/E/A or R/E/A/F, at some point you will want to consider investment in this kind of radio system.
Construction
There is construction to consider for contest flying. Are you going to fly in woody, nostalgia or perhaps builders class contests? Each of these have guidelines as to materials, perhaps the date of the design of the plane and there may be a requirement that you build it yourself from a kit or from plans. Know your guidelines before you buy your next contest plane.
The message is, if you are flying for your own enjoyment, then fly what you wish. If you plan to fly competition, whether serious or just for the fun of it, like me, know what is permitted so you don't find out your beautiful new sailplane is not permitted in the contest you plan to fly.
Over time you may accumulate several planes so that you can fly in a variety of events. Or you may choose planes according to weather conditions. Whatever the case, they do tend to find their way into your hanger over time.
KITS vs. ARFs
The concept of kit and ARF apply to these planes and the amount of work can vary greatly. Most wood kits require you to build the wing and fuselage and cover it. Most composite "kits" have fully built wings and fuselages. You may have to install or buy pushrods, control horns and other small parts to complete the kit. Some come with extensive instructions and some come with almost none.
Wood or composite ARFs usually come almost fully assembled requiring very little work other than installing the electronics. You might have to mount the tail or glue in a supplied push rod but an ARF should come with everything you need.
So contact the supplier, or read the specs or the build manual carefully so you will know what work has to be done and if you have to budget for other parts that may not be included in the package. If you are comparing prices, you need to take this into account.
Other Considerations.
Most of my flying is sport flying. I just love sailplanes. Getting up in a big thermal and staying there for an hour is wonderful. I fly many different planes for sport and I enjoy them all.
I also fly in contests both at my club and in a competition league. It is a lot of fun and a great learning experience. www.flyesl.org
You don't need the World Beater 2000 super plane for sport flying. And you don't need a super plane to enter a contest either. But if you have the budget, go for it! |
