Some assembly required being the ultimate understatement, I finally have my 3 lane, 42' BestTrack assembled.

I have the K3 Micro Wizard timer. However, my track came with three sets of sensor holes... progressively sized from small (shortest distance down the track) to large (furthest distance down the track). Which do I use. I can't locate anything in the instructions that specifies or indicates a difference. Currently I'm using the large (furthest) hole.

Which brings up my real concern:

Last year we ran our council races on a 4 lane 42' best track. Basically (to the eye) the same track. Our car ran in the low 3.1s -

On my new track, that same car is running up in the low 3.3s... and my new cars are in the mid-high 3.1s. Needless to say, this isn't the benchmark (or results) I was hoping for.

I understand all tracks will be different... and I'm fairly sure last year's track didn't have the update.. which I understand will produce slower times.

Help? /images/boards/smilies/smile.gif

do you know what the angle of the hill is? it should be 27.1 degrees. the way you have the start switch set up will also affect the times.
