Smoke System
Plumb the smoke tank the same way you were plumbing the fuel saddle tanks. Fix the smoke
tank with a strap of double sided velcro in the V of the intake ducts on top of the equipment
board. We are using two balsa spacers to elevate the smoke tank about 20 mm above that
equipment board, which makes it easier to access the M4 bolts and to handle the removable part
of the equipment board.
Build one (or two, depending on the smoke pump type you use) smoke injectors. This is a very
individual task, but our recommendation is to make sure you can easily remove the injectors in
order to remove the integrated engine unit through the rear of the fuselage without a brass tube
sticking out of the system too far and getting in the way. IF you install a single smoke injector you
can install it from the top through the carbon cone, as long as it is short enough and slightly out of
center, so that it can pass the fin tube socket when sliding the duct in from the rear. You should
also take care that the smoke injector
tube clears the canopy hatch when
sliding it back into position on the
main fuselage, and that it isn't in the
way when removing the bypass cover
to quickly access the engine. A bit
tricky, but it can be done and it is the
best way to do it.
Finally install the Powerbox Smoke
pump into in the V of the intake ducts
as shown on the photos. Of course
other smoke pumps can be installed
as well, but the Powerbox Pump is
perfectly suited to mount in the tight
space.
