Super Sicroly II (oz16157)
About this Plan
Super Sicroly II. Radio control pattern plane. Wingspan 63 in, for 60 engine.
Note the Super Sicroly II (oz9817) appeared in RCME, August 1974. This here is the later MK kit (distrubuted in Germany by Simprop).
Quote (google-translated): "CONSTRUCTION DESCRIPTION for the SIMPROP model SUPER SICROLY II.
In model aircraft, as everywhere, technical and sporting development is largely determined by international excellence. It is precisely in competitions between the world's best RC pilots that it becomes most apparent which remote controls, motors, and models perform best under the toughest conditions and make a decisive contribution to the participant's success.
SIMPROP-ELECTRONIC has long strived to include the best and most outstanding designs in its product range and now offers the currently most successful RC model, the Super Sicroly II, following the Blue Angel (oz5825) of Japanese aerobatic world champion Tsugutaka Yoshioka.
It is the model of world-class pilot Harm Prettner, and became known at the latest when the young Austrian pilot achieved first place in all rounds at the World Aerobatic Championships in Gorizia, taking the aircraft as the clear winner in the overall standings. Only in the then newly introduced final competition of the top five finishers was Hanno Prettner relegated to third place.
His most significant victory to date with this aircraft came in early December at the 'Tournament of Champions 1974' in Las Vegas USA, where he clearly outpaced the world's RC aerobatics elite. (Incidentally, this was a double success for SIMPROP-ELECTRONIC, as Wolfeing Matt took second place - also with the new SIMPROP alpha-CONTEST system.) The trade press wrote: 'Hanno Prettner flew his tried-and-tested SUPER SICROLY, with which he has so far remained undefeated in the new FAI program. The overall flight pattern in the individual maneuvers, especially in the rolls, is so balanced that it's hard to imagine a better-flying model.' (F. Fleischhacker in FMT 1/75)
The SUPER SIRCROLY therefore guarantees every competition pilot, and of course the average RC pilot, a certain technical advantage over their competitors, because it is specifically tuned to the new requirements of aerobatics. Of course, this model - like every aerobatic aircraft - is a series of compromises, but Hanno Prettner has proven in a series of victories that it is certainly one of the best designs currently available.
We congratulate you on choosing the SUPER SICROLY II and wish you much enjoyment with this model, the expected successes, and many happy landings. Your SIMPROP ELECTRONIC.
Preliminary Remarks: The model you are viewing is one of the world-renowned KATO construction kits. These products are characterized by high-quality wood, precisely prefabricated individual parts, and clear and well-detailed construction plans. You will particularly notice that almost all individual parts are punched or milled ready for installation, that holes are pre-drilled, and all recesses are already machined by the manufacturer – a service that is not included with all model kits. However, don't let this tempt you into hasty assembly.
Before beginning any planned work, read the relevant sections of the assembly instructions and locate the position of the individual parts in the top view, side view, and the ample cross-sectional drawings. In addition, each more difficult construction phase is further illustrated by an additional working diagram. Carry out all work on a sufficiently large, stable, and absolutely flat construction board, as your model will later be just as straight (or crooked) as your construction base.
For all bonding, unless otherwise recommended, use white wood glue, such as Ponal. Since it takes some time for the water it contains to evaporate, the bonded parts must be secured. You will need some screw clamps for this, or pins for lighter bonded parts. During the evaporation time, you can still check the positions of the parts to be glued.
Select only the required material for each construction phase from the car material package. This way, you won't lose any individual parts. The naming of the various components used by Kato is somewhat unusual, but you'll quickly get used to it.
Fuselage and Tail Unit: 1st Construction Stage: Line your building base with plastic sheeting and select the upper and lower halves for the rear fuselage end and the front section of the fuselage side from your material pack. These parts are cut from 5 mm balsa wood and are butt-glued together. You don't need to do this on the plan, as a seamless assembly ensures the side section is properly aligned. Next, glue the inner side reinforcement made of 3 mm plywood onto the balsa boards in the correct position. It overlaps the glued joints and must be aligned at its outer edges..."

This is torture, I'm half way through building a Curare from plans printed out from your site at the moment, and now this!!Just wondering if the Sicroly has the same wing as the Curare from a quick look at the plan

Hi Steve, Wow, you've done an excellent job here. Hats off to you. I'm amazed at how you digitally restored my 40 year old Super Sicroly II plan.
Greetings from Switzerland

Notes
* Credit field
The Credit field in the Outerzone database is designed to recognise and credit the hard work done in scanning and digitally cleaning these vintage and old timer model aircraft plans to get them into a usable format. Currently, it is also used to credit people simply for uploading the plan to a forum on the internet. Which is not quite the same thing. This will change soon. Probably.
Scaling
This model plan (like all plans on Outerzone) is supposedly scaled correctly and supposedly will print out nicely at the right size. But that doesn't always happen. If you are about to start building a model plane using this free plan, you are strongly advised to check the scaling very, very carefully before cutting any balsa wood.
