Hi! I'm new to the diecast racing community and I've been starting to build some tracks of my own recently for YouTube. I have found a couple issues along the way. It all comes back to the starting gate in the end. I see 3D uses a small actuator to set off the starting gate.
Does anyone know where I can get one like his? I looked on Amazon but I don't want to buy the wrong thing since I don't know much about electronics.
I'm also wondering about a track timing system, that'd make things a lot easier for me.
Here's a video if anyone wants to look and give opinions on what I could improve. (The background is boring white because I have to film in my family's garage and the track gets built, recorded on and taken down in about a day.)
