Ours was 40cm. We only use 45 cm for 9+ meter distances to minimize our HS+TS. At the recent tournament, the required distance was 5.5m. Our TS+HS was 146.5.

How slow is your car going because our ramp is 50cm tall and it goes between 3-4 mphjoeyjoejoe wrote:Ours was 40cm. We only use 45 cm for 9+ meter distances to minimize our HS+TS. At the recent tournament, the required distance was 5.5m. Our TS+HS was 146.5.

Miles per hour?? Ok, let me get out my calculator to convert from meters per second......
Yes, at 45cm we are getting in that range. At 50cm we got around 4 to 4.5 mph.

Isn't it against national rules to ask for advice from other Sci-Oly Groups.iwonder wrote:The annoying part about the ramp is the release mechanism... Our first two ES's had different interpretations of the rules... Just out of curiosity, what's everyone else been doing for a release mechanism? We just mounted an exacto knife to the ramp and tie the vehicle up with a string

Umm, that's from a long time ago... And that's the entire point of this site, asking for help and helping others.

Umm if it is against the rules to discuss ideas on a site then shouldn't it be against the rules to discuss rules with each other. Doesn't seem logicalIRONBAT wrote:Isn't it against national rules to ask for advice from other Sci-Oly Groups.iwonder wrote:The annoying part about the ramp is the release mechanism...

Where are you getting this idea of "rules" prohibiting discussing ideas or (the real) rules?????
