About this Plan

Airknocker - Aeronca C-3 - Single channel radio control semi-scale model for .09 power, with a wing area of 420 sq.in. The original was powered with a Fox 10 engine and 8x4 prop.

Quote: - "Scared off by the high powered multi-types? Here's the place to start... out in the pasture with the rest of us... Not a nervous bird, flies slow and easy, lets you get the feel of it, gain confidence..."

Update 09/12/2016: Replaced this plan with a clearer copy, also now scaled up to correct wingspan at 52in, thanks to pilgrim.

User comments

I must admit that when I first saw the Airknocker in the FM magazine back in the early sixties it wasn't love at first sight, in fact I thought "that's ugly". However, over the years it grew on me to the extent that I finally decided to build one in late 2014. Mine is electric powered of course and R/E/T controlled and it is a surprisingly "burly" aeroplane; it has a solid presence in the air, so stable and well behaved that it would make an excellent trainer and I now find the way it looks actually attractive in a chunky sort of way [see more pics 004-006]. The flying surfaces are very easy and straightforward to build, but the fuselage, with its unusual cross section requires more care, in fact mine was a bit of a nightmare! Whilst not one single part of it is anywhere close to an Aeronca C3, the overall "cartoon scale" effect is such that the origins of the design are immediately apparent. Specifications of my model are: Weight 25.5 ounces, wing loading 7.7 ounces/sq. ft. Motor BRC 120/140 watt outrunner. Prop APC 9"x 4.7" Slow Fly, Battery 2s 1300. Full throttle watts 80, maximum watts/pound 51.

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.
