About this Plan

Spinifex 100 - Radio control thermal soarer.

Quote: - "Spinifex 100 designed by John O'Sullivan of Nova Scotia, is a Standard class thermal soarer using the Eppler 193 airfoil. Performance is excellent and will handle ballast well, so load it up for slope flying.
The Spinifex 100 is a standard class thermal soarer using rudder and elevator control. Optional spoiler installation is also shown on the plan. The word Spinifex comes from a needle-like grass which grows in clumps in the Australian semi-desert areas (good thermal country). Generally, I use a fiberglass fuselage on this design but reverted to a ply fuselage of the same profile for this version as it is easier to present in plan form. There is no difference in performance between the two versions, and weight and strength are similar. Several variations of this model have been built by a number of modelers throughout Atlantic Canada, and they are to be thanked for their constructive comments. The wing section is the well-tested Eppler 193 which has slight undercamber and adequate thickness to produce a strong wing. Fully sheeted leading edge, webbed spruce spars, and capstripped ribs make for a light rigid wing structure..."

"Hey Steve! Hey Mary! %^) Hope this finds you both well. Been diggin' the old RES/REF classics as of late (they convert to ALES so nicely!) and upon searching for this plan at Outerzone I noticed, to my surprise, it wasn't there! This is the larger 100in version (also Eppler 193) of John O'Sullivan's Minifex 2M (oz5951) another great performer. Blue Skies! Mike"

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.
