"Congratulations to Daniel Peirce for Certifying Level 1"

Daniel successfully launched his Mad Cow Honest John rocket on an H128-10W with great results:

  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.

Here are the Gorge Rocket Club Launch Dates for early 2017.
Bring your rocket and your own engines.
There are two per month, one at Wyeast (which is a larger field and can accommodate larger engines and rocket), and Westside, please note location carefully .For WyEast Middle school, we will be in the school track behind the school (on west side). For westside, we will be somewhere in the field based on wind direction. Just follow the rocket blasts! We are in the process of assessing a new area in Parkdale that may be for feasible for launching the bigger class motors.  "IF" that does happen, then the dates and locations may change.

If you know you are coming, it helps to RSVP via email so in case there is a last minute change due to weather or launch site change beyond our control, we can let you know. Otherwise most launches are scheduled to go regardless of all but impossible launch weather. If it is windy, we suggest using smaller engines (A) and cutting a hole in the shoot or using streamer recovery.

Rocket Builds: We would like to schedule another build of a different type of rocket - slightly more challenging than the last. Because these kits can be more expensive, it would help to get a head count of those who would be interested in doing this. The day would most likely be a Saturday in February. We can instead do a contest  on individual builds, if you prefer, like building a creative rocket or other as long as it is safe to fly. Please respond to this email with your preferences and we will try to make them happen over time.

Fees: If you came to a rocket building class or launch in 2016 and paid the rocket club fee, these launches are free to you. If you would like to join, you can come to the shop or launch and fill out a waiver and it is $15 per family or $10 per person for the whole season (bring cash or check or if you need to pay by credit card please go through HR Community Ed because 100% of the fees go to them to pay for launch site). A parent or guardian is expected to be present for children, these are not supervised launches.  https://hoodriver.cr3.rschooltoday.com/public/costoption/class_id/3557/public/1/sp/
