Rocketcar Day : Slow motion Launches
Rocketcar Day 11. Slow Motion Montage
Things to spot apart from how great slow motion is.
- pipe car: engine a bit low so it makes it rear up. Wheels a bit wobbly but good soft rubber helps it hang onto the road
- brain car : was going pretty well but i think too short. 6 wheels didn't seem to hurt it though, maybe helped it stay straigther for longer.
- pipe car 2 : this was basically the same car as the first one but was a bit lighter due to having a smaller driver. Same engine position, interesting how much more flippy it was
- spinning trebuchet of doom: obviously, don't do this. Amazing in slow motion though.
- london bus: engine too far above wheel base. Obviously the lid flying off into the crowd not a good vibe.
- recorder car: pretty good but too short. Maybe if it had a drogue, it wouldn't have been spun around before it got going.
- long black car : This in theory should have been good. It had the length, but i suspect the engine direction did not equal the wheel/chassis direction
I think the basics are still true. It's a balance of:
- car needs to be straight
- the engine / thrust vector needs to be in line with the wheel base
- the wheels should be oiled and soft to cope with the road bumps
- point your car straight to start with (watch out for the road camber)
- a drogue helps stopping the car spin before it gets momentum up

Launch Compile
Let's be honest. These cars are not in it to win it.They do add a lot of fun to the day however. Next year, we'll be racing these cars together to speed things up.
Multicar Plus M&M Explosion
Great collection of cars, the crowd gets targetted then a car full of m&m's explodes inches from the starting line, attracting hordes of children. Classic.
Thanks for the vids Ash aka Alex and Ian
