Samba RES Evo 2m

The Samba RES Evo the most sophisticated version of the well liked Samba RES F3-RES high-start launched glider. Like the previous model it is beautifully cut from the best quality balsa and ply, however this version can be built to a weight of approx 420 g, giving a very low wing loading an even better duration and light lift capabilities.

The fuselage uses a nicely shaped balsa pod with a carbon tube boom to minimise weight and wetted area. The wing has a partially sheeted Dbox wing as the best compromise between low weight and torsional strength. The small Dbox cut outs are designed to avoid any airfoil discontinuities and so retain laminar flow and minimise drag. The wing also utilises a carbon spar to achieve such a light weight.

The Samba RES Evo comes with all hardware and a superb full size plan and build manual (in German). An excellent English build manual can also be downloaded from here.

Due to the clear photos and well thought out design the model can be easily assembled by any modeller with a little experience. The holes in the Dbox centre panel shown in some of the photos are of a development model and have been removed from the production version to improve strength and rigidity.
