About this Plan

Yellow Jacket. RC sport model, for Astro 15 electric motor. Note Yellow Jacket and Mini Jacket (oz5859) are the same design at two different wingspans.

Quote: "Get into electric power with one of the Jackets. They are slow and majestic in the air, yet will loop, roll and spin.

The Yellow Jacket was originally designed for the Astro 10 Flight System. The first version of this design flew during the 1978 flying season. It was a tremendous success and inspired several members of my club, the Toledo Weak Signals, to try electric flight.

Equipped with the Astro 10 the Yellow Jacket is a sport trainer, its slow and majestic in the air and is very easy to control. It has no bad flying tendencies. Even the stalls are minor with no violent loss of altitude. The Jacket will fly off a paved flying surface. Because I fly from a grassy field I generally hand launch. The Yellow Jacket will climb lazily to an altitude of several hundred feet. If you are a sport flier, the Yellow Jacket will respond. A little bit of down trim to allow some speed to build up and the Yellow Jacket will loop, roll and spin. It's a fun airplane to fly!

In late 1978, the Astro 10 System was replaced by a more powerful Astro 15 Flight System. For those of you who haven't seen the Astro 10 or 15, both these motors use the same case. The difference between them lies in the internal winding of the motor. In addition, the Astro 10 uses a smaller battery pack than The Astro 15.

The first flight with the Astro 15 was astounding. The Yellow Jacket climbed like a homesick angel. This same model has been flown dozens of limes. It will do consecutive loops from level flight. Full right rudder and full up puts it into a snappy snap roll. If this command is held, the model goes into a beautiful spin. Wind penetration is excellent. And yet when you turn off the juice and ease in up elevator, the glide is flat and slow - almost that of a glider.

The Yellow Jacket with either the Astro 10 or Astro 15 is a fun to fly sport model. Best of all it can be flown at a local park or schoolyard since it makes no noise.

With the fuel shortages and the scarcity of flying sites in metropolitan areas, electric powered models offer the RC'er the ability to keep flying closer to home and yet keep the neighbors off your back.

Mini Jacket: For the 1979 flying season it was decided to reduce the Yellow Jacket in size so that the highly popular Astro 05 system could be utilized. The original Yellow Jacket was photo reduced to 88% of the original dimensions, The Mini Jacket is the result. This model is the most pleasant surprise of all. From the very first flight I knew that the Mini was one of those lucky combinations that results in superb flying performance..."

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.
