I've tried it at 230 mph in a Harmon Rocket around an impromptu course in Arizona that we made up, but Reno is the real deal. All we (the guys and me) did was to fly in loose formation down low at, what to us, was high speed until we scared ourselves, quit, and left to eat lunch.
High speed to Steve Hinton or Steve Hinton Jr. is another thing entirely. Those guys are GOOD. I am not in their league, but am a safe Cessna / Piper pilot. It's a matter of both experience and the weight and power of the planes you have flown. I've flown 260 hp. These guys are flyng at 50 feet and horsing around 3,850 HP mounts that don't take it kindly when you screw up or get sloppy. The planes I flew were engineered to fly well and very mildly compared with 1,500+ HP WWII fighters that will roll on you if you aply too much power on a go-around.
I understand the correct procedure on a WWII fighter go-around is to appply as much right rudder as you can and adjust the throttle so you fly straight. If you apply more power than that, you will roll slowly into the ground and cannot recover without reducing the torque (power).
I had some torque with the modified Van's RV, but the torque on something like Voodoo or Strega must be amazing.
260 HP cannot overcome the ailerons or rudder on a Van's RV-type aircraft unless you are stalled or close to it, so it's a blast without the same level of risk ... at half the speed. I don't think the skill is linear, it follows a much higher slope than that. It's not unattainable, but does require training that most can't afford without Uncle Sam footing the bill. Some CAN afford it.
I wish I happened to be one of them, but am not and very probably never will be .. unless the lottery is kind to me. So far, it has been like a fickle girlfriend.
