I saw a massive bit of bulding steel, it was steel wires crisscrossing to make squares about 15 cm across. Forgetting the wheels on my ansmann virus are about 4cm wide i gunned it towards this `ramp`. my tires went straight through the wire squares adn the frnt of my car hit the wire. there was a few tense moments until i found out nothing had broken!!
Another time i ws with my mate in a skate park with my 1 18 SCT. I had fitted a 3c lipo to it and managed to under estimate how powerfull it was. I went straight for the biggest ramp (about 2.5m high) and my car went straight up, cleared the railings (1.5m further) and managed to go 2 metres higher straight up!! it came down upside down, and also managed to survive, although the servo and battery leads had been pulled out!
