Throttle Curve Setup
The engine's carburetor butterfl y valve provides
non-linear engine response to throttle changes
(greater power increase between low throttle to
50% than 50% to full throttle). We recommend
using the Throttle Curve feature on your transmitter
to provide a more linear response.
Using these Throttle Curve settings, shown
from a Spektrum
DX18 transmitter screen shot,
™
with a properly setup throttle linkage will provide
a very linear feel to the throttle.
Attaching the Fuel Lines
1. Ensure you have set up the throttle linkage
as described in the Connecting the Throttle
Linkage section. It is very important that the
low throttle and high throttle endpoint travel
of your servo be as close to even as possible
(i.e. Low throttle, trim closed -100%, high
throttle 100%). A variation of as much as
10% between these two values is tolerable.
2. Enter the numbers from the diagram into your
transmitter's Throttle Curve menu and activate
exponential (if applicable).
3. Once the engine is started and running
correctly, check the feel of the throttle
response. Adjust it to your liking through your
transmitter's programming screen.
1. Connect medium or large diameter fuel tubing
to the carburetor and the fuel tank supply line.
2. Connect medium or large diameter fuel
tubing to the fuel tank vent line. Run this fuel
line either around the back of the tank or
make a loop on top of the tank to create an
"anti-syphoning" loop. Take the other end of
the fuel line and route it outside the airplane
fuselage.
We recommend you use an external fuel fi tting
in order to fuel the airplane without needing to
remove any hatches or cowls.
