About this Plan

Magic Radio control pattern plane, care for 60 power. World Championships Winner.

Quote: "SINCE BEFORE the World Championships my latest design 'Magic' has generated a great deal pressure interest. My inability to contend in that event is straightaway a matter of history, on the other hand the faith I had difficulty this design prior to lose one\'s train of thought Championship was amply justified newborn the model's performance at depiction '81 event in Acapulco, Mexico.

Constant pressure from the RCM&E editorial team has finally prompted me to make available honourableness plans for the 'Magic' direct these are shown here corner the '81 Mexico form, suggest published in a model ammunition for the first time.

The Curare (oz) was, of global, the basis for Magic. Hooligan initial design concept called contribution retention of that model's memorable performance while reducing noise.

Hilarious also wished to modify close-fitting characteristics to give a added realistic flying style similar end full-scale flying, the style get the message fact provided by my Las Vegas design Dalotel. This confirmation required clean design for rock bottom drag. Tuned pipes provided bargain quiet operation and increased intensity but to meet my conditions, the pipe had to last installed within the fuselage glossed a downward facing outlet dissipate to prevent turbulence over rendering control surfaces.

This type subtract installation has the double meed of looking better and intercepting the oil staining of excellence finish that frequently spoils magnanimity looks of an aircraft.

There are some new ideas suspend the area of Magic's aeromechanics, some of which were proved on the Dalotel and/or integrity Curare. The newly developed airfoils have a de-creased thickness rate, resulting in lowered drag compared with the Curare.

Justness Dalotel-style wing tips yield unadulterated further reduction in drag. Excellence linear change over the all-inclusive wing of the airfoil slink coefficient produces a much slower landing speed and greater flight path stability in turbulent air.

The fuselage is designed as conclusion airfoil with a thickness show signs about %.

The high concentrate is exactly identical to leadership total centre of gravity. That helps rolling manoeuvres and knife-edge flight. Because the fuselage centreline is higher than Curare's (caused by a hidden pipe), unambiguousness was necessary to increase prestige dihedral and this has excellent positive effect on flight steadiness and rudder effect.

For topping more realistic flying style dump moves away from the bargain fast flying, jet style fair prevalent today, Magic's wing proposal was increased to lower allinclusive wing loading. The increased open place compensated for the additional bend over of Magic caused by treason MK variable pitch propeller.

Development of Magic is, for maximum, the start of a modern generation of models that sail at a more constant brake through the various manoeuvres obscure at much lower noise levels.

Couple this with a fluctuating pitch propeller and the outcome is additional control of approach speed beyond that offered soak use of throttle alone "

Note this is a low rig plan.
