location to the cowl.
Make the cutout starting small and increas-

Use the same method to locate the needle
valve and glow plug access hole.
This completes the glow fuel conversions.
Balance the model in the same place as the
electric. We used the same spinner as the
electric version (Carl Goldberg 1-3/4”)
Props from 8-3 to 9-5 will work on the .15,
just make sure you motor will turn the prop
you choose at the proper RPM.
14. Up grade the servos from micro to mini. It
may be necessary to reinforce the mounts.
Important Information:
This is a 3D airplane and you must use throttle control to
avoid over speeding the plane and inducing flutter in the large
control surfaces.
