MXS-R

3D printed version of Nigel Lamb´s MXS-R.
This is a versatile model that can be used like as sports, race  or aerobatic plane, compatible with PLA/PETG or LW-PLA, by choosing one or the other material the flight characteristic will be different. In the case you choose LW-PLA the airframe will be more optimized (read more), you will get the same wing loading, therefore the same agility and in general the flight characteristic of an equivalent model made with balsa wood or foam, but of course for a much lower price! If you chose PLA/PETG, you will enjoy a great racer, the extra inertia will give more stability at higher speeds. You don´t know which material to choose? Just print both because the cost is ridiculous!
