There are holes with blind nuts for
the supplied engine mount, but
since I was using the G-20, I used
its back plate as a template to drill
the new mounting holes and
installed 8-32 blind nuts.
Using two 1.4" wood blocks as
stand-offs, the engine was bolted
to the firewall and the throttle
pushrod was added. Note: Due to
the RF output of a gasoline engine,
I could not use the supplied metal

Zenoah G-20 Spotlight
Zenoah G-20EI
Zenoah 20cc Electronic Ignition Gas Engine
Zenoah's groundbreaking G20Ei isn't just Zenoah's first engine
with electronic ignition, it's the first gas engine from any
manufacturer that can fit .60-size planes that, until now, were
limited to glow or electric power choices. Its dimensions are
especially well suited for round cowl models like Hangar 9's
popular Corsair 60 and P-47D 60 ARFs. It has plenty of power
for many .90 to 1.20-size sport applications as well. Much of this
incredible versatility can be attributed to its lightweight
magnesium-aluminum alloy crankcase that gives it an
impressive thrust to weight ratio compared to most gas engines.
