Here is an update on what I'm currently thinking of putting into production at some point over the next year or two.
It is a Pattern/3D Hybrid that is designed to use the AXI 4130/20 motor for peak performance.
It has an approx. wingspan 0f 80" and should weight around 5 pounds, which includes retracts.
One design feature to note is the use of double hinged flaperons, that more accurately change wing camber, for greater control surface torque and efficiency. The inboard part of the aileron is also enlarged to take advantage of prop-blast when hovering, etc.
Here is what MotoCalc has to say about its predicted performance using 20 Sanyo RC2000 cells:
Aerodynamic Notes:
With a wing loading of 17.2oz/sq.ft, a model of this size will have trainer-like flying characteristics. It would make an ideal trainer, for use in calm to light wind conditions.
The static thrust (105.1oz) to weight (80.8oz) ratio is 1.3:1, which will result in extremely short take-off runs, no difficulty taking off from grass surfaces (assuming sufficiently large wheels), and vertical climb-outs. This model will probably be able to perform a hover or torque roll.
At the best lift-to-drag ratio airspeed, the excess-thrust (58.8oz) to weight (80.8oz) ratio is 0.73:1, which will give very steep climbs and incredible acceleration. This model can easily do consecutive loops, and has sufficient in-flight thrust for any aerobatic maneuver.
