About this Plan

The Scorcher. RC gas model. 1/2A pylon racer. Holland Hornet power. Note this file contains the full size plan of the Scorcher (raster), and also vector tiles at 8" x 10.5".

Quote: "Been thinking about R/C pylon racing? If so our top small R/C man has come up with a real 1/A hot-rod. Reports filtering from West coast say it really moves.

Are you a good radio control model flier? Can you 'sense' what your model will do if it starts to 'go ape'? If not, then get a test pilot for your first flights with this new 1/2A pylon racing design. It's not for a beginner - in straightaway flight it has been officially clocked at 50.4 miles per hour, and that means it will be hitting around 65 mph in some diving maneuvers. Now, when you fly a 32inch model that fast, you know you'Ve got a real Scorcher on your hands!

Many of you regular readers of MAN, on looking over the photos and plans of the Scorcher, will observe a close resemblance to the .09 Gasser which was published in MAN in 1959: That's true; the Scorcher is a modification of the Gasser (oz2505) design, reduced for the smaller engine, but with certain appearance requirements intended to enhance the interest in the new proposed 1/2A pylon racing class.

Before we go into the construction and flying characteristics of the Scorcher, let's talk about 1/2A pylon racing for a minute. Do you recall the tremendous shot in the arms that free flight modeling got with the introduction of the 1/2A engine? Similarly, it is already evident that the new small transistorized radio receivers like the F&M Pioneer, Citizen-ship LT-3, C&S-501, and others, operating on 3 volts, open up a new market in radio control flying - one that will mushroom in volume..."

User comments

Almost 60 years ago I flew and enjoyed Ken Willard's "Gasser" design as a very hot rudder only model, powered (very adequately!) by a Cox .15 Special. When it came to looking for a model for a recent build off, my Outerzone search came up with the Gasser's little brother, the Scorcher, and I decided that an electric version of this would be fun. This version has a 120 watt outrunner and 3S lipo, is built exactly as per plan apart from the addition of a spruce spar in the 8% thick wing and a change to a bolt on wing, weighs just 16 ounces. Covering is document laminating film under heavyweight Modelspan tissue to produce a very stiff airframe [more pics 005, 006]. The model really lives up to its name and really "scorches" around, being as aerobatic as any rudder/elevator/throttle model can be expected to be.

Some pictures of my latest construction: Ken Willard's "Scorcher", ID:oz1184 [more pics 007-012]. Electric version powered by a TT OBL 2924/14 (1430 RPM/V), APC s 7 x 4 prop and 3S 2200mah lipo battery. The only modifications, on the original plan, has been the slight increase of the rudder and fin surface and the spruce spar. Covering with Ora-Cover. An excellent "Sunday Flyer"!!!! Saludos from Spain.

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.
