Glow Engine Conversion
You may wish to convert the Laser to a glow engine. We recommend no larger than a .015 which will
give very good performance. You will need to install a thicker firewall, up-grade the servos from micro to mini,
and reinforce the motor box. None of the material need for the conversion is included in the kit.
1. You will need a motor mount and mounting
bolts for the your motor.
2. Mount you motor to the mounts and meas-
ure from the surface of the table to the front
of the thrust washer (surface the prop will
mount on).
3. Measure from firewall to the front of the
cowl.This should be approximately 2-1/4”.
Using your measurement from the motor,
adjust the length of the motor box. Our
motor measured 3” from table to prop hub
so we cut 5/8” off the motor box length (1/8”
clearance from front of cowl).
Cut the motor box off to the proper length
cutting a 2 degree angle for right
thrust.(approximately 1/16” shorter on the
right side).
4. Epoxy the 1/4” firewall in place between the
original motor box sides and bottom.
The cross braces on the top of the motor
box can be removed.
5. Sheet the bottom and both sides of the
motor box with 1/16” plywood.
