You can go full throttle usually. Some tracks have a bar entering pit lane where if you went to fast you would clip your wing and crash. But on exit it's usually fair game to go full throttle and it's more track/ pit lane / pit guy dependent.

Great videos you have produced. If you have time, could you please make a tutorial for beginners about learning to make jumps. I think going around the track, brake into and accelerate out of corners beginners like I can learn without causing much damage to the vehicle. The jumps are a very different story. There’s just no tracks with short or medium jumps for beginners to learn. Tracks are built for racing so there’s no compromise. Even for a single (properly build for veterans), for beginners it is long. Sure I can apply enough throttle and speed to clear the jump, but most likely I will fail during landing, break lots of parts in the process. When you started your RC long ago, how and what did you to conquered the jumps? Was it simply just crash and learn? Thanks for producing all these very good videos about maintenance and track walk.

I don’t drive nitro but I appreciate this video because you didn’t ruin it with music so you can hear what the car is doing What does the nitro gun do It’s amazing the technology go pros have in them to be bounced like that and give you such a clear picture How many laps or time are these races Great driving
@RyanLutz
@RyanLutz 4 жыл бұрын
Thanks for the comment Steve. I tried music in one of my videos and it’s so divisive. So learned to just let the natural ambiance be. The fuel gun is quicker at refueling than the bottle and can be done cleaner. Basically stick the end in the tank and pull the trigger and fuel dumps into the tank and you can see the fuel level stop dropping when it is full. Yeah I am thoroughly impressed with the GoPro stability and durability. This was one rough track! Most our races are done by time. Qualifiers can be between 5-10min. The finals for Nitro can be 45min through and hour sometimes at the biggest events.
@nomusicrc
@nomusicrc 4 жыл бұрын
Ryan Lutz so it looked like the gun fit in your hand I thought it would have a tube going to the fuel but I guess that would slow you down so it must hold the same amount as the tank in the car I can’t imagine driving the same car for 45 minutes I’ve brought multiple cars and driven for hours but not the same one lol
