Free plans for Extra 300S 60

Extra 300S 60. Radio control sport-scale model, for 60 power.

The Extra is a rather 'square shaped' 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 lite-ply. 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 300S 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. When you have a feel for your Extra 300S, the throws can be increased to high rates to really showcase the aerobatic potential. The Extra performs surprisingly well on a ball bearinged, Schnuerle ported .61, and even better with a .91 4-stroke, but seasoned experts will surely want to get the most out of the Extra by strapping on a .91 2-stroke or a 1.20 4-stroke.
