Lanier R/C BF109 Building Instructions - Warbird Combat
Warbird Combat
Assembly instructions

Use the 15” 2-56 pushrod, golden
clevis and jam nut and attach to the
carb arm. Insert the other end
through the e-z connector on the
throttle servo and adjust linkage.
Trim the clear canopy to fit on the P-
51 and install using ZAP canopy
glue. The ZAP canopy glue is white
and dries clear and sticks very well
to the abs plastic or paint.
For Combat flying I don’t use a
switch, one more item to break. You
can use a dremel tool and cut a 1/2”
long slot 1/8” wide in the side of the
fuselage just above the forward
wing hold down dowel. The battery
lead and power lead from the receiv-
er can be routed out this slot and
plugged in when ready to fly. If you
wish you can install a switch in the
fuse side.
The CG should be on the main spars
at the side of the fuselage. Mark the
location on the top of the wing next
to the fuselage and invert the plane.
If you don’t have a balance stand,
place one finger on the marks on
each side and the plane should sit
level or slightly nose down. Add
weight if necessary to make it bal-
ance.
The control throws should be 1/2”
up and down on the elevator on low
rate and 3/4” on high rate. The
ailerons should be 3/8” low rate
and 5/8” high rate. The elevator
throw should be adjusted so that a
full up elevator loop does not cause
the plane to snap out. If the plane is
snapping out in loops or tight turns,
reduce the elevator throw.
Install the engine between the
beams and twist the motor to the
right. This will give a small amount
of right thrust which is all you
need(1 degree).The top part of the
nose ring will probably have to be
removed to not interfere with the
carb. Mark the location of the
mounting holes and drill the mounts.
Install 4-40 blind nuts and mount the
engine using 4-40x 1” bolts (bolts and
nuts not included).
