86. I
nstall, connect and adjust the engine’s throttle and choke
c
ontrol linkages.
87. Connect the rudder and elevator servos to your radio’s
receiver; attach an 18-inch servo extension to the radio
receiver’s aileron channel; route the servo extension up
through a cockpit, and connect the aileron extension to the
aileron’s Y-cable.
88. Make any necessary additional engine access, exhaust
and/or cooling openings in the cowl.
89. Install and attach your radio’s battery to the radio’s
ON/OFF switch.
90. Optional: Re-install and latch the radio compartment
covers in the floor of the cockpits; and install pilot figure(s).
91. Attach the muffler to the engine; secure the cowl to the
fuselage; and mount a 22 × 8 propeller [59:09].
Congratulations! Assembly is finished!
Setup and Adjustments:
1. The Jenny’s center of gravity (CG) must fall within +
1/2-inch of 5½-inches back from the leading edge of the upper
wing (i.e., Lift the airplane at the center of the upper wing’s spar and the fuselage should hang with the tail slightly
lower than the nose) [59:52]. If necessary, move the batteries or add weight to the nose or tail to ensure the CG is
correct.
2. Check the heat-shrink covering material’s joints and surfaces; if necessary, carefully use a dedicated covering-
material iron and heat gun to secure the edges and to tighten any loosened areas.
3. Check/adjust servo centering, direction and end-point adjustments. When you pull the right stick toward you, the
elevator should deflect upwards; push the right stick to the right and the right aileron should deflect upwards and the
left aileron should deflect downwards; push the left stick left and the rudder should deflect to the left as viewed
from the rear of the fuselage. Please review your radio’s instruction manual if you require assistance with any
radio-related servo-adjustment questions.
4. If you are using a Computer Radio: Set all linkages for max. possible deflections; then, soften the aileron’s and
elevator’s control throws by selecting 60% or more exponential (use 30% exponential for the rudder).
If you are using a Non-Computer Radio:
Low rates
High rates
Ailerons ........ +20 degrees ............. +35 degrees
Elevator ......... +25 degrees ............. +30 degrees
Rudder .......... +25 degrees ............. +30 degrees
5. Trim adjustments: The ailerons & rudder probably require no adjustments (they will remain centered, as
assembled); however, be prepared to set the elevator trim depending on how slow or fast you fly. (i.e., If you like to
fly at slow, scale-looking air speeds, your Jenny’s elevator will probably require a bit of up-trim.)
Preparation for Transport and Field Setup:
1. Disconnect the Y-cable from the left and right wing-panel’s servo extensions.
2. Lift the Jenny’s tail for access to the center bottom of the lower wing, and use the supplied Allen wrench to remove
the two(2) 50 cm (2-inch) hex-head bolts at the front and the two(2) 63 mm (2½-inch) hex-head bolts at the rear.
3. Return the Jenny to its wheels; carefully pull to separate the left- and right-side pairs of upper and lower wing panels.
4. To re-attach the wings, add dry lubricant (graphite or equivelant) to the joiner tubes, and reverse the above procedure.
