Kathy's Clown (oz11238)
About this Plan
Kathy's Clown. Radio control Quickie 500 racer.
Quote: "Even if you don't get to race it, this simple to build 'Quickie 500' design by Cliff Stone will give hours of aerobatic fun. Kathy's Clown, by Cliff Stone.
Back to the future: Quickie racing is here at last, first conceived in the USA about 20 years ago! Glenn Spickler designed a model he called Quickie 500 (oz6868), bolted a K&B 40 FS on the front and surprised everyone at the flying field. That was the birth of what we now know as Quickie 500 racing. Dimensions have not changed since those first days, all are geared to standard 3 and 4 inch wood sizes. The wing can use 48 in wood as a one-piece structure, the original Spickler design was a built-up wing, hence, the 47.5 in constant cord thickness rule, plus tip. That first model set the standard; it was quick to build with 500 sq in of wing - hence the name which has stuck.
It strikes me that Quickie has a stability not seen in the other racing classes. Model dimensions and general layout have not changed in 20 years, a credit to the original concept. 'Kathy's Clown' has been designed to meet the rules and concepts governing Quickie 500 racing in the UK although, as with those early designs, she is not tied only to racing, fun flying has been considered as a practical option.
So, to the glue and string! To build KC requires the minimum of experience, time and cash but, as with any model, accuracy and weight are important. There is little that could not be found in the average aileron trainer. A weekend in the workshop, building with superglue, epoxy and aliphatic resin, will see the basic model complete. Attention to details takes a little longer. However, a further week of evenings will see Kathy's Clown in her element.
Having been around R/C models for 25 years, my stock of spare bits and pieces is vast but it was decided that everything must be currently available from your local model shop. So a visit to Steve Blake's Models in Luton was arranged. An hour or so later we emerged with every thing required for the basic machine. Be assured, there is nothing specialist required.
The wing is foam and I obtained mine for the prototype from Barrie Lever Models. Lever wings are more expensive than most but, because of the cutting system used, an accurate wing can be assured, and they come complete with a carbon trailing edge. Until you have worked with this type of wing, it cannot be appreciated just how good they are, saving time as well as giving peace of mind.
The wing is quite conventional, but do not be tempted to cut corners - those wing braces are functional. Use 24 hour epoxy resin to glue them in..."

* 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.
