TOMAHAWK FUTURA<br />
T<br />
The Tomahawk supplied tailpipe is a 5070<br />
dual wa1l tube, which not only helps to keep<br />
weight down but also protects the tailplane<br />
assembly from convection heat. The forward<br />
section of the tailpipe is single wa11ed but<br />
sufficiently surrounded by enough air within<br />
the fuselage to keep the radiant heat from<br />
affecting the fuselage structure.<br />
Power<br />
The chosen engine for this project was the<br />
mighty Jets Munt 160K and, as such, the<br />
installation was as easy as it gets. Again, there<br />
is just so much room that you can mount your<br />
ancillary engine equipment anpvhere around<br />
the engine compartment and be fooled into<br />
thinking you have inadvertently left some<br />
components out, as once installed there is stil1<br />
enough room to mount another.<br />
The smoke system used came via an Orbit<br />
variable speed smoke pump which was fed<br />
from two smoke supply tanks mounted<br />
beneath the engine suPPort rails.<br />
The flying surfaces on the <strong>Futura</strong> are Kevlar<br />
embossed with live hinging except for the<br />
rudder, which uses a removable fu11-length<br />
hinge pin. Also another nice little time saver<br />
fiom Tomahawk is that all servo mounts came<br />
pre-sized and ready to accept standard sized<br />
SETVOS.<br />
With this build we decided on a different<br />
approach with regards to the power system.<br />
Most jets this size end up with reguiated<br />
power boards and multiple batteries, but we<br />
wanted to retain the multiple batteries for<br />
redundancy but did not want to use a regulated<br />
power board as the power demand from the<br />
servo and electronic set-up used is well within<br />
the rated capacity of Orbitrs Powerjack<br />
married to a single Futaba 6014 2,6 GHz<br />
receiver. Dual Duraiite A123 batteries supply<br />
unregulated power via two Fromeco Zodiak<br />
switches.<br />
For those that do not know anlthing about<br />
these Zodiak switches, I have to say they are a<br />
nice piece of kit and essential when using 4,123<br />
The orbit variable speed smoke pump works fine<br />
