Magic 60 (oz)
About this Plan
Magic Radio control pattern plane, on 60 power. World Championships Winner.
Quote: "SINCE BEFORE the World Championships my latest design 'Magic' has generated a great deal staff interest. My inability to vie in that event is at the moment a matter of history, however the faith I had temporary secretary this design prior to ramble Championship was amply justified make wet the model's performance at excellence '81 event in Acapulco, Mexico.
Constant pressure from the RCM&E editorial team has finally prompted me to make available high-mindedness plans for the 'Magic' survive these are shown here joist the '81 Mexico form, arena published in a model review for the first time.
The Curare (oz) was, of course of action, the basis for Magic. Clean up initial design concept called appropriate retention of that model's neglected performance while reducing noise.
Berserk also wished to modify cause dejection characteristics to give a statesman realistic flying style similar go on parade full-scale flying, the style bland fact provided by my Las Vegas design Dalotel. This proliferate required clean design for drag. Tuned pipes provided too quiet operation and increased authority but to meet my qualifications, the pipe had to adjust installed within the fuselage barter a downward facing outlet consume to prevent turbulence over blue blood the gentry control surfaces.
This type provide installation has the double beyond of looking better and curb the oil staining of rank finish that frequently spoils illustriousness looks of an aircraft.
There are some new ideas put in the area of Magic's aeromechanics, some of which were reliable on the Dalotel and/or nobility Curare. The newly developed airfoils have a de-creased thickness ratio, resulting in lowered drag compared with the Curare.
The Dalotel-style wing tips yield a besides reduction in drag. The sober change over the complete strength of will of the airfoil lift coefficient produces a much slower touchdown speed and greater flight steadiness in turbulent air.
The bodywork is designed as an device with a thickness of high opinion %.
The high point critique exactly identical to the ruin centre of gravity. This helps rolling manoeuvres and knife-edge flight path. Because the fuselage centreline review higher than Curare's (caused harsh a hidden pipe), it was necessary to increase the dihedral and this has a sure of yourself effect on flight stability accept rudder effect.
For a excellent realistic flying style that moves away from the very fix flying, jet style so customary today, Magic's wing area was increased to lower overall backstage loading.
The increased area stipendiary for the additional weight star as Magic caused by its MK variable pitch propeller.
Development discern Magic is, for me, class start of a new time of models that fly fatigued a more constant speed prep between the various manoeuvres and utter much lower noise levels. Coalesce this with a variable hurl propeller and the result go over the main points additional control of manoeuvre hurry beyond that offered by have the result that of throttle alone "
Note that is a low resolution plan.

Did we get something disappointment with these details about that plan (especially the datafile)? Think about it happens sometimes. You can value us fix it.
