I'd say that beast is worth somewhere on the order of $15-20K. The engines alone run $5-8K. Add in all the rest of it, and yeh, minimum $15 grand.
Those engines are microprocessor controlled turbines turning at around 20,000 rpm
. Not very large either, the ones I saw at a hobbyshow a few years ago were about 8 inches in diameter and about a foot long. Very precision machined bits n pieces. Very expensive to watch go plop in the mud. I got out of RC after busting a $120 .61 piston engine
and mashing the reciever on my radio
. Imagine that beast augering in at warp 6. It'd leave a nice dent. Theres a vid out there of a B-52 that did the same. Instead of two turbines, this one had 8 if memory serves.
