Hysteria 600. Free flight power competition model.
Quote: "A really good contest gas model should win or place second at least 50% of the time. To do this, it must be more than consistent - it must also be hotter than its competition. Consistency and high performance are elusive qualities in the same airplane. When you get both, however, you are tough to beat. The Hysteria 600 is a blown-up version of my 1968 1/2A Hysteria, which has racked up an 88% average of first or second places this year. The 1/2A version suffers in class A competition against larger ship-engine combinations however, so it makes sense to take advantage of the rules with a true Class A ship.
The '600' has been impressive in two contests to date, and should be a great ship for the 1969 contest season, which for me, will be about twelve contests. It is tough enough not to require a mid-season overhaul (and re-trim), and so far it has only dropped one max in twelve competition flights (that one was a 5-second motor run - I goofed), so it is hot enough. I haven't made any major trim changes in it since the third test flight. In other words, it also seems reliable and simple to handle.
600 square inches of wing may sound like a lot for a .15 engine, but observe the ultra-low aspect ratio, which is a way of cutting climb drag down, yet does not appreciably hurt the glide with so light a wing loading. The ship now weighs 18.75 ounces after two months of existence.
I've finally gone to boxier fuselage construction to add strength, reduce warping, and save weight. It really is worth the few extra minutes of build-ing time. Nothing is new in wing and stab construction - I have tried other methods recently, but always conclude 'bird-cage' is best for light gas models.
I'm also convinced the K&B .15 is the best class A fuel engine around - it will hold a setting beautifully and it is a true screamer. For B, I have used a Fox .201 (with no changes in model trim needed), but I'm still looking for a light, hotter B engine - perhaps a Super Tigre 23. I realize Starduster 600's fly well with .29's, but the Hysteria would probably suffer from the ultra low decalage this would necessitate. The best route is a .15, .19, .201 or .23 combination with the bigger engines using the lightest possible case castings. On the subject of power, I have now fitted a tuned pipe to the K&B .15 but haven't had a chance to test fly it. I question the necessity of tuned pipes on unlimited ships..."

Did we get something wrong with this plan? That happens sometimes. Help us make a correction
* 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.
