For many the turbine powered jet needs a deep pocket and also the experience of many hours of RC flying. Although airframes have come down somewhat in price and vary between traditional balsa - ply construction and the more popular composite construction, the latter strong but light. We will talk about foam later.
A few of our members have turbine powered jets and attract a lot of attention when they are present up at Cashmoor. The smell of kerosene and the whine of a turbine is something to enjoy.
Turbine power requires a lot of avionics on board to enable the model to fly. Safety devices to cut off the highly imflammable fuel or a onboard fire. Pumps and regulators all add to the expense and that is not including the fuel which is burnt at an alarming rate. A gallon doesn't last long but that 8 - 10 minute flight is something to behold and enjoy. An adrenalin rush to appreciate!
