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 a clean low drag airframe, generally around half power is ample to maintain a
comfortable cruise speed.
Fine trimming can now be carried out, and once the model is correctly trimmed we suggest that a
few handling manoeuvres are performed at a safe height, for example turns in both directions, slow
flight, a clean stall, etc, etc. When happy with the handling of the model it is recommended that the
model be slowed down, the undercarriage lowered and flap applied into landing configuration and
a simulated landing approach is flown at a safe height, so that descent rates and flight attitudes at
various throttle setting can be observed. With this completed the model can be flown through basic
and advanced aerobatics until it is time to land.
The Xcalibur+ is a fairly simple model to
land, a normal approach should be flown
to stabilise the model and slow it enough
to lower the undercarriage, once aligned
with the runway the flap can be lowered in
stages until full flap is applied – note that
more power will be required due to the
increased drag of the flap. You will find that
the Xcalibur+ is very stable in the landing
configuration and it should be relatively
simple to position the model for an accurate
touchdown, the stability once on the ground
being excellent due to the wide track of the
main wheels. If new to turbines then it is
wise to fly a few landing approaches at a
safe height to become used to the relatively
slow acceleration of turbines and the descent
