Keep looking at 4S 5000mah 50C battery but have a feeling this is overkill.

Help much appreicated

Future shock would way closer to 2 Kilos.

Is this the model?
Designed by Bill Evans, Future shock is the latest in the Simitar Series of tailless aircraft. It has a balsa-and-ply fuselage and a foam wing, and the plans show two versions- electric powered and glow-powered. Patterns for the foam wing's root and tip
Additional Information: are also included, and foam wings are available from Soaring Research. WS: 56.5 in.; L: 32 in.; power: .25 motor or .40 glow engine.
If so 3 or 4 S lipos at about 3000mah should be enough. (Assuming that the motor you selected is really appropriate!)
