15 years ago a mugen supersport or a kyosho turboburns would set you back about $1200.00 us, the first futaba's pistol grip fm-pcm were about $800.00 us.
I am a Kyosho suporter, buil a Kyosho kit and then build any other kit and you will understand the cost. I did not rim one single pice of plastic on my tki or se it all fits and moves freely with no binding.
