Yea not easy to keep straight gotta stay focused!
Range is no really an issue, I am running the car in the first vid from at least 500ft away passing myself then about 100ft to stop after with a futaba FASST 2.4ghz radio.
When it does go out of range (rarely) or the battery goes low on the car the reciever hits the brakes for me.
That's awesome. I played with short course trucks a little bit. They where fun. I can imagine what it's like trying to control those at that kind of speed.
It would look pretty bad I may be able to recover a wheel and the wing lol.
I walk down the whole thing to clean up random rocks before I run It's a 3 mile long fresh paved greenway for bikers/walkers/runners.
I wait till it's clear do my walk and make a few runs, I probably use around 200ft of clear space before and after where I am standing.
I gotta fix my helicopter. I'm into the flying machines. Bad thing there is, you tend to jack shit up more often. I had a Corsair I used to fly that was clocked at 145mph. Then I did a high speed pass at about 80' into a 90° straight up climb. There must of been a crack in the wing spar I hadn't seen on inspection cause that thing just exploded in mid-air about 100' off the ground. I never even found the motor. Just some pieces with servo rods hanging out. LOL!
