Gator RC Propeller & Back-Plate Drill Jig

The Gator RC Propeller & Back-Plate Drill Jig is a precision alignment tool designed to simplify and improve the accuracy of drilling RC airplane propellers and spinner backplates. Built from hardened steel, this jig helps ensure accurate and repeatable hole alignment for many popular RC gas engines including HP-50, DA50, DLE50, DLE55, JC51, DLE30, EME60, EME70, RCGF, and other compatible engine platforms.

Accurate drilling is critical for reducing vibration, improving spinner alignment, and ensuring smooth engine operation. This drill jig helps eliminate guesswork by providing a reliable guide for consistent drilling accuracy during propeller and spinner installation.

The knurled outer diameter provides improved grip and easier fixture removal during use.

Why Use a Propeller & Back-Plate Drill Jig?

Properly aligned spinner backplates and propeller mounting holes help reduce vibration and improve overall engine smoothness. A drill jig allows more accurate hole placement compared to freehand drilling, helping prevent wobble, imbalance, and uneven spinner rotation.

This is especially important on high-performance gas RC aircraft where vibration control and precise propeller alignment are critical.

Common Applications

  • Spinner backplate drilling
  • Propeller mounting alignment
  • Gas engine installations
  • Giant-scale RC airplanes
  • IMAC and aerobatic aircraft
  • Warbirds and scale airplanes
  • Workshop engine setup

Installation Tips

  • It is recommended to drill the propeller from the back face
  • Back the drill bit out several times during drilling to clear wood debris
  • Do not force the drill bit through the propeller
  • Place the supplied bolt into the first drilled hole to help maintain alignment while drilling remaining holes
  • Always orient the propeller horizontally with blade tips at the 9 o'clock and 3 o'clock position before drilling
  • Correct prop orientation may help reduce propeller and airframe damage during dead-stick landings
  • Use sharp drill bits for best accuracy
  • Double-check alignment before final drilling

Benefits of Using a Drill Jig

  • More accurate spinner alignment
  • Reduced propeller vibration
  • Cleaner and more professional installations
  • Improved drilling consistency
  • Helps prevent damaged backplates
  • Saves setup time during engine installation
