I help design & draw parts for cutting edge pylon racers as a 2nd/3rd job.. been out to see them a few times.
Very impressive stuff.
Very expensive hobby.
Reaching towards 350kph real speed, one wrong twitch of thumb and it's $1500 written off.
Upwards of 40g in the turns, something structural fails, $1500 written off.
Not perfect design, wing gets tip stall at full speed, $1500 written off.
Engine cuts out at wrong time for one of many reasons, $1500 written off.
You get the drift
