This a 115 kph Optica of 2.36m wingspan, weighing 8kg wet (7.5kg dry) and powered by a Griffin Turboprop driving the same 25cmx25cm 5-bladed fan as the thegibson's original Edgley Optica_EA.
This AV was inspired by helohero's Optica turbine_AV, and addresses most, if not all, of the shortcomings of both the original EA and helohero's AV.
At 115 kph max speed the model still flys in a scale-like, realistic,fashion. Landings are easier and the model is generally more pleasant to handle.
Negative 100% (-100%) exponentialhas been added to the throttle channel to give more precise control of the turboprop engine at lower power settings, and some washout has been addedto the outboard wing panels to alleviate the wicked tip stall that the model was prone to.
Wheel brakes can be applied by pushingon the stick, i.ie. giving 'down' elevator.
To take-off, set half-flap and run the engine up against the brakes until you get full power, then release the brakes and go!
To land, work through half-flap then set full-flaps, and reduce speed to about 60-65 kph.
Mike C has produced some marvelous colour schemes for this model; Optica G-BGMW_CS and the very colourful U S A 1_CS, both available on the Swaps.
Many thanks (yet once again) to the very talented Mr Gibson for his beutifully detailed Edgley Optica_EA, and to helohero for inspiring me to produce this AV.
