(For future reference, this question better belongs in the other thread
, this forum is for sharing questions to study for the test). The event is no longer about speed, with a minimum time of 5 seconds, which considering the times less than a second with similar masses last year, even with much less propulsion, should still be very attainable with a decent propeller and motor. The main challenge now is to reliably slow the vehicle down to even slower times. However, if you are unable to make you car run in 5 seconds with the additional mass, it might not be worth the risk.
