Bristol F2B Fighter ARF 15
The engine installation is related to the type of
engine that you have chosen. We like to show
how we installed the OS 1.20 engine and
including a "scale" type functional manifold.
To ensure an unrestricted air inflow we removed
three panels of the screen above the propeller
shaft.
We also installed deflection ducts made of 0,5
mm alu sheet to force the air close to the
cylindre.
To prevent the air from stalling, we opened two
1" holes in the fire wall into the open cockpit.
This with the additional outlet created by the
functional manifold gave a satisfactory air flow.
We also installed a remote connector for the
glow-plug as well as an on-board glow battery
that is engaged at idle.
The tank has been installed diagonally in the
engine com-partment to allow the use of a
standard available typ.
For this aircraft there are some additional items
available separately (allow for 3 months delivery):
ACC-401, Cockpit interior kit, consisting of in-
strument panel with all instruments, valves and
switches installed, pilots seat (vicker chair),

diam alternately.
