About this Plan
SPINsation. Profile tailess sport model for radio control. Forward-swept wing. MVVS .40 engine shown.
Quote: "Congratulations on your purchase of the Morris Hobbies SPINsation! The name pretty much says it all on this unique design. We wanted an airplane that would pretty much be a show stopper every time it flew, and we succeeded! This design lends itself to having the sticks thrown into the corners at any attitude and speed, and the results are always exciting. To recover, just let go of the sticks and it instantly recovers. See Tips From the Knife Ace at the end of this manual for tips on how to perform a Lomcevac, a Pinwheel, a Pinwheel Spin, a Climbing Flat Spin and the indescribable 'Falling Leaf'.
Warning. Do not let the versatility of this design mislead you into using more power or speed than you should. The same precautions apply as do those on the 'wing on a stick' designs. Specifically; Use low pitch (4in) props to keep speed reasonable, and never use full power in a dive. Fatal flutter is a real possibility in a model, like this, that is designed to be very light and maneuverable.
This is not to discourage you from using a strong engine. Excess power is a lot of fun. We highly recommend either the powerful MVVS .40 engine with the tuned silencer, or the IRVINE 46 (along with the MVVS Tuned Silencer), either of which will pull a four pound SPINsation vertically out of sight. But we want you to remember to USE THE THROTTLE, and save full power for vertical climbs, lomcevaks, flat spins, etc.
Construction Notes.The entire SPiNsation is built by pinning it to the plans over a flat surface (the plans should be covered with wax paper). Thin and medium C/A may be used for all construction.
TIP: When securing end-grain balsa to other balsa, the C/A works much better if the open grain is misted slightly with a water bottle prior to applying the glue.
1. Assemble and secure the six die cut pieces constituting the 3/8 Balsa Filler.
2. Pin the Balsa Filler in Place on the plans.
3. Cut, sand as necessary, and pin in place each of the 3/8 x 3/8 Sticks (to form the basic outline of the fuselage and fin).
4. Trim and secure each of the 1/8 x 3/8 sticks and the 3/8 x 3/8 Hardwood Gear Strap Retainers.
5. Remove all pins and block sand entire fuse to remove any high spots..."

User commentsA very fun plane to fly. I need to build another....sold mine decades ago. If you build one, it flys fairly easy, and lands reasonably slow. However, when recovering from a manouver, and decending, allow it to settle before pulling up elevator, it doesnt panic recover well at all. Just give yourself some time to get used to the flight characteristics.

* 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.
