adjusted to suit your nosegear unit and wheel size. If necessary, adjust the nose gear leg
length to have a little positive incidence when the plane is on a level surface, and we suggest
about +1.5° to 2.5° degrees at the wing roots.
Steering uses a pair of pull-pull wires to the servo which is mounted in the milled plywood R/C
install plate, as shown. Depending on the type of steering system used, you will probably find
that you need to install the retract towards the back of the ‘U’ shape, so that the steering arms
do not touch the plywood bulkhead. You can use 2 small rubber bands on hooks to hold the
loose steering cables out of the way of the leg when it is in the ‘up’ position.
Experience shows that a trailing link type of nosegear leg/oleo gives the best ground handling
and steering with the Rookie, and our new Behotec units come complete with a simple leg of
this style, as shown below.
C-ARF/Behotec Landing Gear tips:
All the 3 wheels are double-ballraced and these are a tight fit on the ground steel shafts. Press
them in carefully, using a little grease, making sure you don’t push the bearing out of the other
side of the wheel.
Note the orientation of main wheels and
brakes - the wheel has the raised central part
on the
outside
of the wheel, not the brake
side! Do NOT forget the small aluminium
tube spacers between the brake hub and the
wheel (see photo), or the first time you use
the brakes on landing the wheels will lock-
up. (don’t ask how we know!)
Replacement tyres will be available for this
gear, and are very easy to fit.
There are 2 short aluminium tubes supplied to
centre the nosewheel on the brass axle -
make sure to fit them the right way round for
perfect centering. (see photo right)
The nosegear unit should be installed about
7 - 8mm from the back of the plywood
mount. The steering arms are fitted in the
lower holes on the oleo leg, and the 2 set
screws in the upper threaded holes. Don’t
forget to grind small ‘flat’s’ on the steel pin
and secure the set-screws with a little thread-
locker.
The steel pins that are fitted in the retract
blocks to connect the oleo legs are secured
with a single 6mm wheel collet on top. Make
sure that the steel pin does not project thru’
the collet more than 1mm, or it will hit the
inside of the retract unit when operated.
