Scuba Tank
RC turbine jets is not for the weak hearted or weak pocket booked. This stuff is expensive, there is no doubt about that. In addition, it's still RC airplanes. Anyone who has been in this hobby for a while knows how quickly stuff happens, and if an airplane is loss. $7K plus gone just like that - snap, one minute here, next minute gone. We know it's not "if you crash", it's just a matter of "when you crash". It happens to all of us at one point in time or another (sometime sooner rather than later).
If one stretched to your budgets endpoints to fly a RC turbine jet, and complaining about every dollar you spend, then this is probably not the part of the hobby for you. The best thing to do is to find a part of this hobby or another hobby that is more affordable for your budget.
How can one even enjoy this hobby constantly complaining, and whining about its cost all the time. OK, so your not rich, we ain't holding that against you guys. We don't want to hear you belly aching all the time. It's not about money, spend what you can afford, and if you can't afford it - you can't afford it, but stop the whining !
I'm not not whining because I can't afford the $25 million dollars it cost to hitch a ride on a Russian spaceship up to the international space station for a weeks vacation. I would love to do that, but it isn't going to happen.
