MD-500D Magnum PI Version 500 Size Helicopter Scale Conversion Kit from Roban - RBN-KF-H500DMG5

This is the 500 class conversion kit of the MD-500D helicopter, a light utility civilian and military helicopter developed in the 1970's and still going strong today.  This paint scheme is based on the Magnum PI version displayed prominently in the popular 1980's TV series.  Designed to take your Chaos 500 or Trex torque tube versions and transform it into a very scale RC version of the full scale helicopter.

There is no extra parts to purchase to get this beautiful scale fuselage in the air.  When you open the box, the fuselage is completely painted in standard automotive base coat and clear coat for a super gloss finish.  Included are fiberglass landing gear and aluminum skids, a magnetic cabin lock system for quick access, transparent front window, and side windows that open for heat dissipation. Also includes tail fin parts, mounting accessories and landing gear.

This fuselage can be completed in as little as 4-6 hrs and is intended for the intermediate to advanced builder.  No modifications needed when using stock mechanics and stock rotor head.


  • Fully painted fiberglass scale fuselage
  • Fiberglass landing gear and magnetic cabin lock system for quick and easy access
  • Extremely detailed surface and molded panel lines
  • Use of 500 standard equipment (6S Battery, 1400-1600kV motor), fly with your existing parts


  • Roban MD-500D Magnum PI Version 500 body kit
  • Scale fiberglass landing gear 


Important Information - Please Read

Roban Scale Helicopters are intended for modelers who have advanced level building skills. Both ARF and KIT product formats require you to install your own electronics (ESC, servos, motor, etc). KIT product formats also require you to install your own helicopter mechanics. Because helicopter mechanics can vary greatly in size and shape, you may be required to modify the fuselage slightly (including cutting, drilling, etc.) to achieve a perfect fit. Roban fuselages are all handmade from fiberglass and therefore may have slight variation in tolerances between body panels, doors, or windows. These variations do not affect flight performance and can be easily adjusted by an experienced builder with proper tools. These precautions are intended for novice builders; an experienced modeler should have no issue achieving perfect results with these premiere scale helicopters kits.

Build quality was not so much.... Wood platform was epoxied in crooked and the chassis sits at an angle. Looking from the front side looks crooked. Horizonal tail did not even come close to fitting and had to grind the vertical tail in order for it to fit in slot. Set screws holding skid was not pre tapped and didn't even do the job of tightening.
