**Club Trailer**

We now officially have a club trailer and 24 pads. The ground support and safety equipment are expanding.  This would not have happened without the help and support from fellow club members. Blue Mountain Rocketeers from Dayton Washington which has been a great local support to their community for 26 has ended and with the great upkeep of their launch gear and the club, the trailer was purchased by our club. We hope to continue with thei tradtion to "Pay it forward" and mentor others in the safe hobby with mentoring.

  My Background

What is Thrust to weight ratio?

To safely launch a rocket the thrust to weight ratio should be at least 5 to 1

For example, if a rocket weighs 0.4 kg, and the motor has a thrust of 15 Newtons, is this safe?

Answer: The weight of the rocket is 0.4 x 9.8 = 3.9 N. Thrust is 15 N. The thrust to weight ratio is thus 15:3.9, or 3.8:1. This is less than 5:1 so the launch would be unsafe.
