It would make an ideal trainer, for use in calm to > light wind conditions. > The static thrust (3769g) to weight (6330g) ratio is 0.6:1, which will result > in short take-off runs, and no difficulty taking off from grass surfaces > (assuming sufficiently large wheels). > At the best lift-to-drag ratio airspeed, the excess-thrust (2356g) to weight > (6330g) ratio is 0.37:1, which will give strong climbs and rapid > acceleration. This model will most likely readily loop from level flight, and > have sufficient in-flight thrust for many aerobatic maneuvers. > > General Notes: > > This analysis is based on calculations that take motor heating effects into > account. > These calculations are based on mathematical models that may not account for > all limitations of the components used.
