Component Installation Notes – All versions
Do NOT try to run the engine on its own. There is no need nor do we recommend attempting to run the
engine outside of the airframe by way of functional test. With care, the turboprop can be run on a sturdy
test stand with suitable propeller but there is no safe way to do so with the helicopter unit, and there is no
need. The engine has already completed a programme of test cycles at the factory in controlled
conditions. As this is not easy to do safely for your sake and can damage the engine unit by overheating
or overstress we strongly recommend you don´t.
1)
You should have a clear idea how to arrange all the components needed to run the engine inside
the model. The main issues are fuel tank (locate centre of tank to CofG), bubble trap position (if used),
locating the fuel pump in close proximity to the source of the fuel (bubble trap or tank) and adjusting the
receiver and ECU batteries to achieve optimum location for balancing the model.
2)
The 3-wire heavy connecting cable from the engine to the Hub should be carefully routed away
from the engine intake so there is no possibility of the wire being accidentally ingested if the FOD screen
should be displaced for any reason. This is 250mm (10”) on the Heli and 500mm (20”) on the Turboprop.
Please do not modify it if not quite right, ask for a longer or shorter one if required. Avoid placing the
cable close to the engine rpm sensor which is located at approximately 4 O´clock when viewed at the
intake of the engine with the cable entry plug at 12 O´clock. A cable too close can cause some rpm
interference at start-up. The same goes for any servo wires or servos passing near.
3)
The 4mm fuel feed pipe should be routed similarly clear of the intake. Try to have at least
200mm/8” of fuel feed pipe to the engine. Note the connector is indicated with an “F”.
4)
The metal lubrication feedpipe to the gearbox, exits the engine via the connector marked “L”.
Be sure NOT to accidentally connect the fuel feed to this if removed.
5)
The other end of the engine cable should plug into the
small Hub connector unit sited at a convenient (cool) location
for access. You can use the regular small Hub (Hub Lite) or the
Compact Hub with the screen built on, both have same
function. This is also the location to connect the ECU battery.
6)
If you plan to use a telemetry adapter it should plug into
the outlet marked “Data Port” on either Hub unit. Mount it somewhere away from heat, and visible if
desired. If also using the colour display you can connect both using a Y lead.
