The new UPDATED ERC 4-Bolt Drill Jig - New from East R/C!
This premium quality propeller Drill Jig is CNC machined for accuracy and will
withstand years of punishment. Specifically used for drilling propellers that use a 4-bolt or 2-Bolt pattern.
This is an exact match for engines like the DA-50 and DL-50 prop bolt patterns. The center peg is 10mm for snug
fitment while drilling and features a center hole that is tapped at 1/4-20 for added convenience. Can be used with
a hand drill or drill press.
The outer 5mm bolt hole pattern works for: 3W-50 (4-bolt), 3W-60 (4-bolt), TR-50HP, DA-50, DA-50R, DL-50, DL-55, DLE-55, EVO-54, Aerovate-50, OS GT-55, HP-50, XYZ-52, MT70, DM55, JC60, DLA-56.
Additionally, two more 4mm bolt hole patterns were added to accomodate the MLD-35, DLE-30, MT-35, and PTE36R!
*Note* Be sure to use your prop washer to line up, and make sure you select the right pattern before drilling. It's best to mark with a sharpie after you figure out which bolt pattern is yours.
