Engine Adjustments
In some conditions due to high altitudes, extreme temperatures,
etc, it may be necessary to slightly adjust the idle and high-
speed needle valves. The high- and low-speed needles have
limiters that prevent over adjustment.
If your engine starts from the above procedure but won’t reliably
continue to run with the glow driver removed, follow the steps
below.
Low-Speed Needle Adjustment
Start the engine using the above procedure and leave the glow
driver attached. Allow the engine to idle for 30 seconds, then
pinch and hold the fuel line, cutting off the fuel flow.
Correct:
If the low-speed needle adjustment is correct, the
engine increase in rpm slightly (about 300 rpm) and then die.
Too Rich:
If the engine rpm increases a lot (500 rpm or
greater) the low-speed needle must be leaned or turned clock-
wise.
Too Lean:
If the engine doesn’t increase in rpm and simply
dies, the low-speed needle must be richened or turned counter
clockwise.
High-Speed Needle Adjustment
With the engine running from Step 1 above, advance the throttle
to full throttle while a helper securely holds your airplane.
Carefully pinch and hold the fuel line, cutting off the fuel flow.
Correct:
If the high-speed needle adjustment is correct, the
engine will increase rpm slightly (about 500 rpm) and then die.
Too Rich:
If the engine increases a lot (1,000 rpm or greater)
the high-speed needle is too rich and must be leaned or turned
clockwise.
Too Lean:
If the engine doesn’t increase rpm and simply dies,
the high-speed needle is too lean and must be richened or
turned counterclockwise.

Flying the Xtra Easy 2 Trainer
For first-time pilots, the thought of flying their Xtra Easy 2™
Trainer through loops, rolls, and perfect three-point landings
can be thrilling. Learning to fly, however, takes time, patience,
and most importantly, a good instructor. If you’re a first-time
pilot, don’t try to fly your model without an instructor. Seek an
experienced instructor. Your local hobby shop can put you in
touch with an instructor in your area who can fly and trim your
Xtra Easy Trainer, and then give you your first chance on the
“sticks” with very little risk of damage to the airplane. We can-
not over emphasize the importance of having a qualified
instructor to help you through your first flights.
The JR radio system has a built-in trainer system or “buddy
box” option. The transmitter can be used with any JR transmit-
ter and a trainer cord (JRPA130). Use of the “buddy box” for the
first few flights is highly recommended.
More experienced pilots will find the Xtra Easy 2 to be a confi-
dence-inspiring airplane. Its super stable, and slow flight char-
acteristics make pinpoint landings easy as pie. At full throttle,
the Xtra Easy 2 Trainer is more than capable of most sport aero-
batics maneuvers. The self-righting stability of the model also
makes it one of the easiest airplanes you’ll ever fly.
