Anthony or Andy,
Maybe you should post this question in the Giant scale forum. Even though I may tr 60 and 120 size stuff down the runway, my Gonads want to go hide as if I've just been in freezing water, if I'm faced with a 100" ish plane of that cost etc.
$2500 seems a good price, I would think $3000 would be minimum for a 1/3 ARF, engine(80-100cc single) and digital servos(8-10), but maybe pilots of these larger planes need to build up trust in the product, by doing some of the final building/assembly them selves.
