ELF –Assembly Guide © Vladimir’s Models & HyperFlight 2
ELF - a low weight mosquito class 1m span discus launched glider.
The ELF allows the pilot to soar in small places as never before.
ELF’s high tech construction makes the model stronger and lighter.
High prefabrication allows the model to be assembled in one evening.
The ELF gives a lot of fun in a small package!
Ready to fly weight of
only grams!
(Dependent upon R/C, battery and construction.)
HyperFlight Notes
If you don’t want to use the SmartLipo shown in this
manual we have sourced some alternative batteries.
Don’t worry about a switch, just plug in the battery
when flying.
If using 2.4GHz RC use the HyperLipo 2S 175 mAh
LiPo battery and SD100 servos. No voltage regulator
is required because all modern receivers and these
servos can work fine on this voltage (8.4V). This will
give over 2.5hrs RC duration on one charge.
If using 35MHz RC use the Losi 150 NiMH battery,
and any suitable servos, though we would highly
recommend the SD100 - the only servo with the good
centring required by this high performance model. This
will give about 2hrs duration.

Cut and sand the throwing blade so it is
comfortable for you.
1 2
Identify the tip that takes the blade –the
left wingtip if you are right handed, or vice
versa. Fill the wing tip slot with thick CA.
Quickly slide in the throwing blade and fill
any gaps with more thick CA.
3 4
Fill in the slot on the other wing with thick
CA. Optionally add a little weight to
balance. Or fit the other blade so everyone
can enjoy flying your Elf!

1
Mark 50mm from the bottom of the rudder.
Cut a groove for the horn. If using Nuke 3
servos drill horn nearer hinge to inc throw.
2
Fit the rudder horn in place and glue. Then
glue the rudder into the slot in the boom.
3
Cut a groove in the center of the stabilizer
just behind the spar. Do not cut into the
carbon!
4
Remove the V-mount top from the base.
Glue the top to the stabilizer. Do not refit the
wire axle. This photo is wrong! The V mount
top should be the other way round
front

Check the stab can move to max angle
without fouling.

Fit long guides inside the pod and shim
them with scrap balsa or foam.
Attach the pushrod to the rudder horn.
Disregard the photo, use a wire-in-tube
pushrod fitting for the rudder.
7 8
Attach the stab pushrod. The pushrod
outer guides will keep it in place.

Remove the servo mounting lugs and wrap
the servos with masking tape. Optionally
wrap them with Kevlar thread to increase
case rigidity.
Do this with all connectors.
Note the polarity!
3 4
Now thread the wires through all the holes
in the pylon. Put the plugs back. Ensure
the polarity is as on fig 3! Check servos
before gluing in place.
Remove the wires from the plug by gently
teasing each leg and pulling out the wire.

Place RC as above. Centre the output arms & glue servos in place. Trim the pushrods to length, thread on 2cm
heat shrink tubing. Test fit and then CA the Z bend wires to the pushrods. Slip on the heatshrink tubing and
heat to secure joint.Add more CA. Remove servo arms and thread onto Z bends. Tape the battery in place.
Make holes for the receiver antennas

If using a SmartLipo cut a hole in the
sheath for the on/off switch, otherwise
remove the sheath to connect the battery

Program the transmitter
Set the centre of gravity initially to 74mm -
75mm from the front edge of the wing at the
root. Add lead weight as required. Advanced
fliers move the CG back after the test flights if
this suits your flying style.
Program as much rudder throw as possible, at
least 20mm each side.
Set horizontal stabiliser (tail plane) to be
parallel to the boom. Program 9mm of up
elevator (measured at the root trailing edge),
and 9mm of down elevator. Optionally set up a
rate switch to reduce throws for launch.
Start with gentle side arm launches. When trimmed
try 360º launches. Let the model balance itself in the
wind, and make a 360º turn, releasing into the wind.
Do not cantilever the wingtip to hold it against the
wind –this will crack the tip.
Fly safely, do not launch near others.
