About this Plan

Aussie Challenger. RC pattern plane for .60 power.

Quote: "Smooth and sleek, the Aussie Challenger makes a welcome addition to the ASP range of acrobatic aircraft. A classy 66in span performer from down under by John Edmunds and Graeme Smith.

The Aussie Challenger design utilizes a fully symmetrical foam core wing design with balsa leading and trailing edges for strength and durability. Wing construction.

1. Setting up. Select two pieces of foam 32 in long x 2 in deep. Select each wing root end and measure 11 in and mark. Select each wing tip end and measure 6-1/4 in as measured from the straight trailing edge. Connect the two points with a straight line and remove excess foam which will give you a tapered leading edge. Draw an accurate centre line around the foam wing blank. Please note that accuracy at this stage is critical.

To check the centre line at each end make up two sighting templates of 16 x 2 in balsa, fix to each end of the wing blank on the centre lines and visually sight along the wing, ensuring that the two templates are aligned with each other. This will ensure that your wing halves have no twists or warps built in. You are now ready to fix the wing section cutting templates to the wing root ends and wing tip ends.

2. Wing section templates. Make up wing section cutting templates out of thin aluminium sheet, as this is easy to work with. Draw a centre line on the templates and drill two sighting holes as shown on the plan. Attach templates to their respective root and tip ends ensuring that the centre lines accurately align through the sighting holes. You are now ready to cut your foam wing blanks to the correct wing section.

3. Cutting the wing section. Pick out your favourite foam cutter and get your wife, girlfriend or flying buddy to help you through this next section. Place the foam wing blanks on a flat table or building board and place some weights on top to ensure that the wing blank doesn't move..."

Hi Steve, Minor scaling error noted on pdf? Wing span on plan is 64". Should be 66" exact, I think? That would match the original Challenger in 1984. Regards,

Fair point. There is indeed a mismatch, am not sure if this is just how it was printed and published. Can anyone confirm?

Hi Steve, Mary, Many thanks for continuing to run the site! Attached are a couple of shots [main pic, 005, 006] of my build of Aussie Challenger oz10185. Built using the downloaded plan of course :) Beautiful flying model. Mine uses an OS 61 SF for power and standard size servos all round. Regards,

* 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.
