About this Plan

Ollie. Free flight gas model. Wasp 049 engine shown. From plan #951.

Quote: "The aim with 0llie was to get a model that was different from the square wing and tail designs, and square bodies of nowadays, and to have it fly with superior qualities. Two models were made, Bill Mickelsen's and the author's. These racked up 2 firsts, 1 second, 1 third, and a national record for the author in only four contests!

Fuselage is built upon a 1/2 in sq keel; formers of one side are added while on the board. Unit is removed, formers on other side are added. A 1/16 sq stringer is added to each side from front to rear, then the other stringers are added from #4 to rear along with the pylon. From #1 to #4 is planked with medium hard sheet; bend to approximate shape before adding. The rest is planked with medium 1/32 sheet between stringers forming an octagon. Cover entire fuselage with Jap tissue.

Thanks to Bill Mickelsen's unique construction idea, we have a light warp free and warp resistant wing. Cut trailing edge, pin to plan. Lay down leading edge, add ribs. Put required dihedral in, let it dry thoroughly. Cut the soft sheet leading edge (top and bottom) planking and put it on. Don't muff the next step: Put 1/32 hard sheet (grain vertical) in between the ribs from top planking to bottom planking and glue well. While glue is wet, pin section to flat board to assure no warps. The stabilizer is made in the same way.

When a smooth glide is obtained, adjust the model for 100 ft right circle, then for a fast corkscrew right climb - about 3/32 of an an inch left thrust is added for this."

In the absence of the building instructions that accompanied the original plan in Air Trails the plan as presented can (and has in one instance to my knowledge where a builder omitted the sheeting from former 4 rearward leaving an open framework covered by tissue which is not in line with most Nostalgia Rules) mislead builders. The building instructions state and I quote....From former 1 to 4 is planked with with medium hard 1/32 sheet.....The rest is planked with medium 1/32 sheet between stringers forming an octagon...... end quote. Thus the fuselage is fully sheeted. I think this should be noted on the plan to help avoid illegal models being presented but disallowed for Nostalgia events. Just for info, over the last five years my 5in span Ollie with Taipan 2.5 diesel for Nostalgia limited to Burford 2.5 diesels has been very competitive winning many comps including an Astralian title. I have also recently completed a 68in span one with K&B 40 for normal Nostalgia events which

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.
