About this Plan

Gollywock 125. Radio control sport model, for electric power.

The Gollywock (oz6693) was first published by Midwest in 1944. This here is a later version, modified for RC with electric power.

Quote: "I liked the Dynamo (oz12666) so much I decided to build a Gollywock the same size. I created the drawing and started construction. I elected to add a flat center panel and one additional panel to each wing half. This resulted in a wing span of 44 inches with 246 sq inches of area.

The Gollywock is a little simpler to build. It is a box fuselage with an all sheet fin and rudder. I laminated my fin and rudder from two thickness of 1/32 balsa with mylar embedded hinges. The wing is straight forward and does not call for leading edge sheeting as on the Dynamoe.

The resultant Gollywock weighs 9-3/4 ounces for a 5.68 ounce/ sq ft wing loading. How do they compare? Both fly great in the park, club field or back yard. The Gollywock climbs a little better. I ran test with timed 20 second motor runs and got about 2:45 for the Gollywock and 2:35 for the Dynamoe. Both catch light thermals. I swapped wings and got similar results.

The Dynamoe is a little sleeker and looks great with the transparent Ultracote windows. The Gollywock reminds me of an old Wakefield model.

Both are a lot of fun to build and fly."

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.
