Guests On
2010 EMRR Challenge
Contests:   All   Previous   Next

Essence's Model Rocketry Reviews' Challenge is now in its sixth year! Last year's set a new tone and level of competition and we heard many positive comments on the challenge. Most have a common theme: that the challenge has encouraged them to attempt and learn different aspects of rocketry. The back half of 2009 has been a crazy time for EMRR. It left me (personally) feeling like the only way to keep up is if there were two of me... so now, 2010's challenge will help you appreciate that!

Drag Race
Wildman Rocketry Drag Race!

The purpose of our challenge has always been to give our guests some milestones throughout the year while supporting EMRR. This year we will continue with our enhanced "milestones" portion of the contest.

We believe that this challenge will not only help the participants to have fun in our hobby, but will also provide them with some learning experiences. We also believe that by sharing those experiences through the pages of EMRR, that others will benefit as well.

Junior Bonus: If you are 15 or younger, you will receive twice the entries for the drawing level that you achieve. In other words, if you make Silver, you will get two Silver entries for the drawing at the end of the year.

The challenge runs from 1/15/10 - 1/9/11 with the drawing to take place in February of 2011.

  • If we are already on the Announcement eList, do we need to re-register?
    • No. Just let me know what your e-mail address is and be sure to respond to the eList announcements with specific instructions to the EMRR Challenge entrants.
  • If I have a rocket that I built and flew last year but never reviewed, is it still eligible or does it have to be built and flown this year?
    • EMRR can not confirm when people build the rocket. We can only tell when things are submitted to EMRR. The spirit of the competition was that all activities of the challenge would be in 2010.
  • If a challenge has a low point -or- a higher point score, can I submit for the lower point and then go for the higher one later in the year??
    • Yes. Now you are seeing some of the strategy! (note: it is either low pts or high pts, not additive)
  • I was also wondering what happens if you purchase a rocket to review that is on the hit list but after you get started someone else posts a review before you do? Will it still count?
    • Yes
  • Why haven't you updated my score with the Review (or other input) I just submitted?
    • Updates to scores will occur when I post the submissions to the site and I can link to them. But, please, reminders are not frowned upon if after a site update you don't see your score updated!
  • You say "Review" in places and "article" in others. Is there a difference between a review and an article? If so, which submission form should be used for an article?
    • Reviews are something with EMRR ratings (Kits, Plans and sometimes OOP); Articles are everything else without EMRR ratings (MODS, Scratch, and sometimes OOP). In essence, they're the same thing.
  • Do I have to participate in the EMRR Challenge to participate in the "Design this Spaceship" contest?
    • No, but why not?
  • Is a purchase of Rocket Design or Simulation software required?
    • No. My experience is with RockSIM and SpaceCAD, both have a free, fully-functional trial period. There are other software packages available as well (mostly simulation only). Also, note that SpaceCAD has offered a 15% discount to EMRR Guests. Contact EMRR to get the discount code.
  • Does the twice the thrust have to be just twice, could it be at least twice the thrust allowing 3 or more motors?
    • No, twice mean two motors?
