Sky Bench is proud to announce the availability of the famed Original Airtronics Olympic II sailplane kit, better know as the OLY II. We are now producing this great flying and super durable Lee Renaud design.

Dave Garwood's photo's for his OLY ll kit review published in Flying Models magazine December 2004 issue.

The OLY II has been the best beginners R/C Sailplane for years and has taught thousands of r/c sailplane enthusiasts how to fly successfully. The OLY II will stay up on the slightest of thermal activity and produce long flights for the beginner, but don't be fooled into thinking it is only for beginners. The OLY II is still winning contests, Tom Kellevang flew his OLY to first place in the 2000 AMA/LSF Nostalgia NATS and the wind was fierce all day.

The kit was originally designed to build fast and now Sky Bench has improved on that with laser cut wing ribs that are stacked, and ready for immediate use with out needing to be punched out like a die cut kit. The fin is now a one piece laser cut part that saves building time and more importantly makes a much stronger tail section to better withstand a flip over landing. Both the stab and rudder also have laser cut parts to save building time and create more accurate and stronger flying surfaces. The fuse top and bottom are now laser cut and this will also save building time.

The wing leading edges are pre shaped and require minimal sanding, spoilers are optional, but installation is shown on the construction plan. All hardware to complete the model is furnished except the adhesives and covering materials. The 5/16" steel wing rod that joins the two wing halves is a competition level wing joiner.

Separate plans are furnished for the wings and the construction manual is illustrated with lots of photos to make building a snap.


Ron's Oly II

This was my second build after the Gentle Lady. The OLY II had its test flight this weekend and did great. 16 minutes off the winch with very little lift. Looking forward to building the Big Bird.

Notice.......... January 2006

I have been continually striving to improve the OLY ll kit to improve the strength and the ease of assembly.

The kit now includes the Du Bro Laser push rod package and Du Bro metal clevises. This will improve the quality of the kit and make the building more enjoyable.

An electric motor mount former is also included in the kits. Use this to mount a Graupner Speed 600 motor for ease of launching. Other more powerful motors can be used.

Flight Battery and Servo Information:

I use a 4 cell, KR-1400-AE Ni-Cd Flight Battery pack from Batteries America, with a Hitec receiver protection rubber pad (1/8" thick) between the nose block and pack. This fits just right in my OLY ll. I have two quarters for added nose weight. I'm using the larger size Hitec HS 300 servos for rudder and elelvator.


Electric Motor mount former for Speed 600 (included in kit)
One part $1.85. Shipping is $1.25 for up to 4 parts or zero shipping cost if ordered with other items.

New OLY kits


OLY ll S ... a Very fast building kit!

Looks just like the original OLY ll, but the airfoil is changed to S 3014 for great penetration. The wing's leading edge is D-Tube balsa sheeted, top and bottom, for a more accurate airfoil shape and added strength. The OLY ll S will float very slowly without out dropping a wing tip prematurely, but with a couple clicks of down elevator will fly in 10 - 15 mph winds easily. Construction Plan shows flaps and/or spoilers, builders choice, kit is supplied with the spoilers and plywood horns. The OLY ll S wing will not fit on the regular OLY ll fuse. If your building a sailplane for the first time, the OLY ll wing is a bit easier to understand since it doesn't have the wing sheeting to install. Look at the instructions linked below and decide which kit you would like to start with. Both wings are two piece for easy transporting.

The OLY ll S or OLY ll will be a terrific choice for electric powered installation. Electric powered sailplanes is the most convenient way to learn how to fly RC sailplanes, the most convenient way to launch them and probably the fastest way to successful RC flying. The best way to really sharpen your flying skills is launching from a Hi Start or Winch. Both kits include a laser cut plywood motor mount for Speed 600 or 700 motors. Other motors will require adapting the motor mount. See Hobby Lobby for sourcing.

I guarantee you will be impressed with the performance level of my new OLY ll S design. ... Ray ...

OLY II S Instructions and Photos (9.7 MB PDF)

Ray's OLY ll S

The best reason to own both an OLY ll and an OLY ll S is the difference in flight characteristics and the similarity.

Especially if you are relatively new to building and flying RC Sailplanes.

If your new to flying RC Sailplanes, start with the OLY ll. If you have flown other Sailplanes and are not intimidated building a D-Tube sheeted wing and built up trailing edge, then don't miss out on flying the OLY ll S.

Both will make fantastic Electric Powered RC Sailplanes.


Here are the set up specifications on my OLY ll S

Flying weight ... 49 oz
Wing Span ...102.5 "
Wing Area ... 908 sq in
Wing Loading ... 7.77 oz per sq ft
Balance Point ... 6 - 3/16" Forward of T. E.
( Wing's trailing edge )

Tow Hook located in laser cut whole in the Plywood Fuse bottom. Approximately an 1/8" behind the balance point.

Rudder throw ... 1-5/8" each way.
Stab max up ... 1/2".
Stab max down ... 3/8".

I build my Spoilers on all of my kits to open straight up, they are very effective that way and that explains why my kits are designed with shorter spoiler blades. The shorter the spoiler blade, the less disturbance to flight performance when they are closed.

OLY ll S ........... It is going to build fast!

Uncovered Oly II SX by Jon Lusk

OLY II SX BUILD

Long cold winter days puts you in the basement building next springs thermo ships. I purchased a Oly II SX from Sky Bench Models in Ind. This is a 100" thermo ship with wing rods not rubber bands to hold the wing on. You can install an elect motor with very little trouble.

I needed a project for the winter so I decided on the Oly II SX with electric power. I chose a Turnigy 2836/8 motor with a Turnigy Plush 30A ESC and some Turnigy Nano-tec 1300Ma 3 cell Li-Polys, a 10-6 and 11-6 folding prop and metal spinner. I hoped I would have enough power to get the 3lb a/c up and into the clouds.

I mounted the motor on a 4ft. piece of 4x4 pine and placed it on the floor, as it went by my nose I pulled the battery lose and managed keep from breaking the prop or the motor. Minor damage to my face and shirt. With the 10-6 prop it pulls 22 amps and 28amps with a 11-6. I guess if it will fly a 2x4x4' it should fly the Oly. The pix shows it ready for sanding, final assembly and covering.

Finished Oly II SX by Jon Lusk

Sorry to say but the Oly II SX-E is finished. I hoped to make the build last for a month and a half to get through the cold part of the winter. It was a fun and a easy build. Installing the electric motor was no problem, with the battery behind the motor, then servos then the ESC and the receiver under the wing rod tube. I installed flaps and cut them out of the trailing edge so they are flush with the bottom of the wing. I had to beef up the trailing edge and flaps with spruce and if I had do-over's I would use 1 1/2" trailing edge stock to make the wing a little more solid and could reflex the flaps for a little speed. The weather was up to 57 today (warm for Madison Wi.) and I had planed to do a test fly, BUT:

It rained all night and water got into the basement and I had to pull up the carpet and rent a dehumidifier. It's now dark, my back hurts and I think I will consume many adult beverages. Will let you know how it fly's this spring, we are having 6" of snow tomorrow and high of 6 degrees on Thursday.

OLY II SX
Kit Price ... $168.95

If you're new to building Woody kits and flying them, I suggest you start with the OLY ll, the #1 trainer kit for thousands of newbies. If you have had building experience, but not much flying experience, choose between the OLY ll and OLY ll S. The difference is in the wing airfoil, consequently, the wing construction. The S has a sheeted top and bottom area between the leading edge and a bit past the spar, plus a built up trailing edge. Both have the SAFETY feature of the wings held on with Rubber bands. This method of wing attachment adds durability to a sailplane while improving your landing skills.

If you are going to install an electric motor, consider the fuse difference between the SX and the original OLY ll fuse. The wings held on by rubber bands means the fuse section under the wing allows super easy access to the large motor/Rx battery. The motor controller allows the motor battery to also power the Receiver, eliminating the need for two flight batteries. The SX requires a battery hatch access in the top of the fuse, long enough to fit the battery system you choose or in the bottom of the fuse. The bottom access requires cutting a hatch in the plywood bottom. Builders choice.

The OLY ll SX has a narrower fuse than the OLY ll and OLY ll S. ( The SX electric motor mount former dimensions are 1-3/8" wide, 1-5/8" tall ). This means less drag and coupled with eliminating the rubber band posts protruding from the fuse sides provides a better performance factor.

Please note: Sailplane Performance starts and ends with pilot skill, in the middle is sailplane performance potential. Beginner pilots need pilot skills first, sailplane performance second. However ... Many, Many contests have been won by the OLY ll.

The OLY ll S and SX can be agressively Zoomed launched from an electric powered winch. They can fly very well in windy conditions due to the airfoil, allowing you to fly more often and more competitively.

The OLY ll S Kit Series are starting a new chapter to continue the legacy of OLY 11.

Flaps will provide the best landing control for accuracy and safety. They can be coupled to the stab in your Tx to provide a slow and controlled landing. They can also be utilized during launch and flying, but there is a learning curve and most pilots over use the flaps.

Tips on adding carbon to the wing spars.


Bill Eckles's Oly III

Hi Ray,

I just composed a long letter, the gist of which was to order a new Oly III. My first one bit the dust today from some sort of launching mishap...I tried to use both hands and managed to get something spoiled in the radio antenna in the process. Earlier in the day she'd specked out, actually faded out in some relatively low marine layer left over from the morning, and it was the "one last flight" that did it. I have truly enjoyed this plane and used her to capture my first trophy, first place in "Sportsman" at Torrey Pines Gulls! The dark blue and flaming orange colors light up the southern California skies, but today she spiraled into the ground in a shallow brush pile under a huge Sycamore that took care of the wings. You should know, the design and build was very strong as she really ripped through some upper branches before meeting her demise.

I am eager to get going on a replacement. Yes, I'll try to learn from this, but really am not skilled enough to rebuild the whole thing...fuse broke in two in front of the wing on impact, the empennage broke, though not badly, in front of the stab. and the wings tore out both joiner boxes. My nose canopy and "lid" are the only entire pieces left!

Don and his Oly III

Hi Ray,

Here's a photo of my newly finished Olympic III, I'm very proud of the way it turned out. I must say that I was a bit intimidated beings this was my first build but when I got the kit, I knew I could do it. All the components were cut to perfection and fit like a glove and was very easy to visualize with the detail in the drawing. This has been one of the best experiences in my life thanks to you and the guys on RCG.

Best Regards,
Don

Thank you Ray for providing such an outstanding kit. Wood selection is superb, fit of all parts is amazing. Plans and instructions are accurate and thorough. I have never had more fun building a sailplane in my life! Everyone that has seen the kit was equally impressed and I count some top-notch builders in that group. I can't wait to build some of your other offerings. So many fine choices, so little time.

Frank and Larry with their elect oly IIIs

Ray,

Just had to let you know how much we love this plane! Larry and I put the Olys up on Sunday and this plane just floats forever! We have Ammo 28-45-2100 brushless motors with 4.3-1 planetaries with 16-10 folders on them. Only took about a 20 sec. climb to get to 500ft. and mother nature provided the rest of the lift. After a 30 min. and 45 min. flight we decided that this is the best glider we have ever built/flown. We only used the power on initial climbout, the rest of the flight was thermal/slope off the top of hill at our field here in southeast Ohio. You will probably get another order for a kit from some of the onlookers that watched in ahhhhhh as these birds flew. Thank you for a great plane.

Ned's new Oly IIs

Hi Ray -

I just want to share with you that I had the maiden flight of a Sky Bench Oly III yesterday evening. First was a hand toss and she flew straight as an arrow and without needing any trim adjustments. Next we hooked her onto a high start and away she went. She rotated perfectly upon release and climbed straight and true. Once aloft there was no need for trim adjustment either for directional or vertical stabilization. My buddy at the field was equally amazed by the flight characteristics of the O3. He flies a Paragon which in his words is a flying brick when compared to the O3. I want to thank you for building such a wonderful product. I believe that with time the O3 will help me to progress quickly up the LSF ladder of skills. I am a new pilot and my first plane was a Sig Riser which was a great plane to learn with. With the O3 I am convinced that my skill level will accelerate in it's development.

Kindest regards,

Ned Burdick
