Top Flite TOPQ7903 - Manual

The following procedure covers the assembly and modifications
required for a flying model. No modification is required for static display
models.
❏
1. Trace or photocopy the Baffle Template from your plans onto a 10"
x 10" sheet of 1/8" lite-ply (not included). Cut around the circumference
and the engine opening with a scroll or coping saw.
❏
2. Trim the Radial to fit the lite-ply baffle with a hobby knife
or scissors.
❏
3. Cut away the prop shaft opening from the center of the Radial.
Smooth the edges with a round file or drum sander.
❏
4. Tape the Radial to the baffle, then test fit the assembly inside the
cowl. If necessary, sand the baffle and Radial for a good fit.
❏
5. (Flight Modification) Trim away one or more of the plastic cylinders
to allow air flow across the “real” engine head.
❏
6. Drill a 1/8" hole through each of the raised marks around the
perimeter of the crankcase and also through the bottom of each rocker
arm cover. Drill a 1/16" hole through the dimple near the top of each
cylinder.
❏
7. Use #240-grit sandpaper to lightly sand the full length of the 6
plastic tubes for better glue and paint adhesion. Cut 18 pieces 2-1/2"
long to use for the push rod tubes.
❏
8. Sand the 16" wire, then cut 1-3/4" long pieces to use for the
ignition leads. Make a 90° bend 3/8" from one end.
WARNING
Do not attempt to start your engine unless the Radial has been modified to permit cooling airflow to the engine!

The Top Flite ® Replica Radial Engine (hereafter referred to as
Radial) is patterned after the Pratt & Whitney radial engines that
powered numerous aircraft from the Golden Age of aviation.
Modeled to fit the Top Flite Giant F4U Corsair, this 1/5th scale
Radial will fit any cowls with a frontal opening of 8" to 9-1/4". Not
only does the Radial enhance scale appearance, but it also serves
as an air-flow baffle for more efficient engine cooling.
