Super 90 (oz4655)
About this Plan
Super 90. Enlarged 150% version of the classic KK Super 60 (oz552) design. This is a modern redrawn plan in PDFvector format.
Quote: "Change made to frame is that I've used two dowels on the front of the leading edge. The tailplane is now held with a dowel at the leading edge and an M6 bolt about two thirds chord. I am also thinking about making a semi symmetrical tailplane section by adding 1/4" sq. ribs top and bottom and sanding to shape. Covering, I'm tempted to go traditional and use nylon and dope (rip stop nylon from kite makers) but then I thinking nylon for the fuselage and Solartex for the flying surfaces - time will tell on that one. I've got an ASP 108 on board which I reckon will spend most of its time at tick over, I would like a 90 4 stroke but haven't got one however we will see what she flies like ...I will make amendments to the drawings after I've completed mine but if someone wants to build one they can from the pdf files."
Note this is a large plan, with 2 x sheets of 9ft by 3ft.

Photos of the Super 90...[see more pics] I've got as far as flying her and she is really smooth and stable. Even simple aerobatics are possible. I eventually secured the outer wing panels with M5 nylon bolts tapped into the lower spars and locating into a 5.5mm dia. hole in the outside end of the 1/2" ply dihedral braces, no elastic bands and what seems like a good system; well its not given me any problems. With the 108 she is a little overpowered but thank heavens for the throttle, an 8 oz tank on fast tick over is good for 10 to 15 minutes. A heavier engine would be really good, a converted 20 cc petrol strimmer motor would put weight where it wants to be. There is a 2 lbs of lead in the nose due to the low weight of the engine; I'm not sure how much this would be reduced with a 90 4-stroke.

* 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.
