1/2A SST (oz5780)
About this Plan
1/2A SST. Super Sport Trainer. RC pylon racer. 33in span, 242 sq in area, for .049 to .051 power and 2 channels. Foam core wing. Model # pl-654. Designed by Vince Micchia. From RCM 8-76.
Quote: "The design goal for the 1/2A SST was to obtain the flight performance in a small, economical aircraft that is usually found only in the larger, more powerful RC ships. Dozens of flights have proven that this little bird does just that.
There is an impressive speed differential between powered flight and glide. Several design factors contribute to this. These are the clean lines, an efficient wing with ample area, overall light flying weight. Notably absent is the drag producing landing gear
Another feature is the use of ailerons rather than rudder in a two channel ship. Besides smoother turns, ailerons allow a greater variety of maneouvers. Whether you want an aileron trainer or a super sport fun ship, you should give the SST a try!
Now for building this bird, we have placed the instructions, supplemented with illuistrations, on the plans so there is no need to duplicate them in the text. The only thing we should mention concerns the wing. You can make templates for the airfoil and cut your own foam cores or you can buy a Sure Flite #2016 constant chord wing kit for $7.95.
We hope you enjoy the 1/2A SST as much as we have."
Quote: "The 1/2A SST was published two months before the Hornet (oz5419) - it had a thicker foam wing that was partially sheeted and also used capstrips. This allowed the foam core to be covered with the plastic films without the pebble effect. The Hornet's smaller fuselage cross section and thinner wing gave it a speed advantage."
Note first published in RCM, as shown here, the 1/2A SST design was also later kitted by Hobby Shack see 1/2A SST (oz10442) for more details, and a slightly clearer plan to read.

Supplementary file notes
Did we get something wrong with these details about this plan (especially the datafile)?
That happens sometimes. You can help us fix it.

User commentsHello! I would like to submit some photos of my finished 1/2A SST, oz5780 [more pics 004-011]. I fly it with a Cox .49 Black Widow at 15% nitro and a 5.5x3 prop. It's a blast! Really funny to fly it. When the engine quits, it shows a really safe gliding performance. If the construction is on the stockier side as mine came out, you will have a nearly indestructible plane that also flies very well. Greetings from Benavidez, Argentina!

Good afternoon. Attached to this email the picture of the 1/2A SST I made with increased wingspan at 115cm [pic 012]. Powered by 2212 2200kv with 7.5x4 folding prop, 30A esc, 2200mAh 3s Lipo, 3 9g servos. Very fun to fly and cheap/easy to build. Thanks again for the work you do of sharing plans! Best regards,

Good afternoon. Attached to this email the picture of my second built 1/2A SST plan oz5780 [main pic]. Thank you for your work and your website! Happy flights and nice landings,

* 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.
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.
