At 1.7m wingspan this is one BIG foamie. Bigger is better and this Grand Tundra flies much like it's original 1.3m version from 2 years ago but in a BIGGER much more stable way. Same big Bush wheels, same big barn door flaps...but there are some awesome new enhancements. 6 part light system is one nice addition as are the turbulators on top of the wing to reduce the stall speed.
