The Revolver .61 ARF is designed to be fl own with a .61 –75
two-stroke glow engine, .81– .91 four-stroke glow engine, or
a RimFire .80 (50-55-500) Outrunner Brushless motor. If

1. Using four 8-32 x 1" [25.4mm] SHCS, four #8
fl at washers, four #8 lock washers, and thread locking
compound, attach the engine mount side-mounted to the
fi rewall so that the engine head will be on the right side.
Leave the screws slightly loose. Test fi t your engine between
the mount halves. Slide the mount halves against the sides
of the engine and fi nish tightening the mount screws.

2. Position the front of the engine drive washer 5-11/16"
[145mm] from the front of the engine mounting box. Mark
the location of the engine mount holes onto the mount rails
using a Dead Center Hole Locator (GPMR8130). Remove
the engine from the mount and drill a 9/64" [3.6mm] or #29
hole through each of the marks you made in the landing
gear rails. Use an 8-32 tap to create threads in the four
mounting holes. Attach the engine to the mount using four
8-32 x 3/4" [19.1mm] SHCS, four #8 fl at washers, and four
#8 lock washers.

3. If you installed a two-stroke engine, attach a Pitts-
style in-cowl muffl er. The stock muffl er could also be used,
but excessive cutting of the cowl would be necessary. We
suggest using a Pitts-style muffl er.
