Take-Off; Slow Flight - BVM Bandit arf Assembly And Operation Instructions Manual

The Jet Take-Off
When the propulsion force is applied at the rear of a vehicle, it is destabilizing. The slower
the forward speed, and the higher the thrust-to-weight ratio, the more problematic this effect
is. A high powered model jet during the early stages of taking off is exemplary of this
phenomenon.
A narrow, paved runway that has obstructions on the sides requires the best techniques.
The first flights should be made in light wind conditions and preferably little or no crosswind.
With good piloting techniques, most jets will handle a 10-15mph crosswind, but save that for
later.
Set the wing flaps to the take-off position and taxi into the take-off position on the centerline
and nose into the wind. Apply about 1/2 up elevator, release the brakes and slowly advance
the throttle to about the 1/2 position. Direction control is primary, first with nose gear steering,
and then as the speed increases, the primary control is with the rudder. Once the rudder
authority is dominate and the model is headed straight down the runway, advance the throttle
to full power. The model will lift off when it has sufficient airspeed.
Retract the gear and climb to a safe altitude and then retract the flaps.
For the first flight, keep the airspeed at a medium level and concentrate on trimming the
model and deciding whether or not the center of gravity is optimum.
The published C.G.'s for BVMJets is on the conservative side - a place to start. You may
want to ease it back on subsequent flights.

TAKE-OFF

The first flights should be made in light wind conditions and preferably little to no crosswind. With
good piloting technique, the Bandit ARF will handle 10-15 mph crosswind, but save that for later.
Set the flaps at the take-off position. (Input 2 clicks of up trim for the first take-off). Hold full up
elevator for the take-off roll until rudder authority is established. The Bandit ARF is a bit nose heavy with
fuel on take-off, so expect about a 200 ft roll and a fair amount of up elevator (3/4") to rotate.
After unstuck, retract the gear and climb to a safe altitude, retract the flaps and reduce power to
cruise speed of about 100 mph.

SLOW FLIGHT

Most of the first flight should be utilized to get familiar with the slow speed flight characteristics.
Select the flaps to the take-off position; there should be no pitch change. Extend the gear and select
full landing flaps; adjust the power to maintain level flight and a speed of about 70-80 mph.
Climb to a safe altitude and slow the model to the edge of a stall to know where that edge is. A good
landing speed will be 10-15 mph above stall. Fly race track patterns at that speed and about 200 ft
altitude to become familiar with the power setting required to maintain level flight.
