Extra 300S 40 (oz12489)

About this Plan

Extra 300S 40. Radio control sport-scale model, for 40 power.

Discontinued kit from Great Planes.

Quote: "Congratulations and thank you for purchasing the Great Planes Extra 300. For the record, the model we have chosen to replicate is the Extra 300S.

The Extra is a rather 'square' airplane with well defined lines. Coincidentally, this makes it exceptionally easy to build and cover - especially for a semi-scale sport model. Framing the model is very straightforward as most of the structure features interlocking balsa and liteply. The Turtle deck sheeting may look a little intimidating but in actuality it is quite easy to apply if you follow the instructions and use the template provided to cut the sheeting.

Flying the Extra 300 is a thrilling experience - as it should be for such an aerobatic model! It doesn't take much elevator or aileron throw to put the Extra through its paces. Of course, the throws can be decreased to low rates (illustrated in the instructions) if you'd just like to take it easy and poke holes in the sky.

The Extra performs surprisingly well on a ball bearing schnurle ported .40 2-stroke but seasoned experts will surely want to get the most out of the Extra by strapping on a .46 2-stroke or a .70 4-stroke.

We hope you enjoy building and flying your Great Planes Extra 300S as much as we did the prototypes. Please inspect all parts carefully before starting to build..."
