1.2. Warning
Consider the basic differences between gas turbines and piston engines.
Turbines will deliver power only at high rotation speeds. Then there will be
a lot of power (see diagram).
Higher loads occur when driving an R/C aircraft model with a turbine
compared to equally powerful drives like propellers or impellers.
This is a result of considerably higher air speeds caused by jet propulsion.
Maximum speeds under jet propulsion can exceed 200 mph, depending on
the model. We would like to remind you that the AMA has issued strict
rules regarding maximum speed for operating turbine powered RC
models. Please refer to the AMA regulations from the link posted above.
Servos should be carefully chosen, at least 1.5 times as strong as for
comparable models with conventional engines. Ultimate Jets supplies a
set of tools to compute servo torque requirements and choose the proper
servo for the task. Please refer to our technical publications.
During installation, seal the intake and nozzle, as well as kerosene joints
to keep dust and debris out of the engine.
Really make sure to:
first inform, then buy
have the fitting size model for your turbine
select servos that are powerful enough
construct servo wiring and rudder joints very carefully and
reinforced
seal the turbine during the installation process
