Balancing | Schwerpunkt
The balance point of the Mini Xcalibur is
115mm back from the leading edge at the
root of the wing panels with the undercarriage
extended and an empty tank.
Der Schwerpunkt der Mini Xcalibur sollte
bei 115mm liegen. Gemessen wird dieses
von der Nasenleiste (Flügelvorderkante) aus

leerem Tank.
Flying the Mini Xcalibur | Den Mini Xcalibur Fliegen
We recommend the use of a long runway for first flights, particularly if this is the first jet model
you have flown. The Mini Xcalibur a good sized model with a matching performance, so it can
cover a great deal of sky in flight - having a long runway and plenty of available air space makes
the early flights much safer and more enjoyable.
Do carry out thorough range checks before flying, both with the turbine shut down and running,
and check for any radio interference caused by the turbine, throughout the rpm range. Also check
all the controls, ensuring that they operate in the correct direction and with the correct movements,
and that there is no slop or lost motion in any of the linkages. Check that all clevises and ball joints
are secure. Any clevises being used must have keepers fitted for added security. Finally check the
retracts to make sure they are operating correctly.
Once happy, refill the fuel and once the turbine is running check that it will hold full power without
any air appearing in the fuel lines which could then result in a flameout on take-off. Taxi the model
out to the runway being used – although flap can be used for take off we suggest that this is not
done for first flights. If the nose wheel is correctly trimmed then no rudder application should be
required during the early stages of the take off run unless taking off cross wind, and once at flying
speed a small amount of up elevator is all that is required to allow the model to lift off, whereupon
we suggest that the landing gear can be retracted and the model allowed to climb to circuit height.
Once at a comfortable height power should be reduced, as the model will quickly build speed being
