20 yearsBack in July of 1995, the efforts of Mike Osier, John Clarke, Jerry Beals, Bruce Dusenberry, and architects Bob Cousins and Kip Merker paid off when the City of Tucson awarded TIMPA the lease to the land we currently occupy. Through the tireless work of these gentlemen and the generosity of Sundt Construction, Calmat Asphalt, and a flying site improvement grant from the Academy of Model Aeronautics, TIMPA was able to create a world class R/C flying site out of a scrubby, old cotton farm. Twenty years later, TIMPA is still considered one of this country’s premier flying sites. Here’s to another 20 years!


NARAM 57 at TIMPA JULY 23-31

NARAM logoOn July 23rd the Southern Arizona Rocketry Association will kick off the 57th annual National Association of Rocketry Annual Meet at the Double Tree – Reid Park. NARAM 57 will consist of three different activities: 1) The competition model rocketry championship (nine different events selected); 2) Sport/High Power rocketry shoot (from 1/8A to a maximum of up to an “L” motor); 3) USA/FAI team flyoffs to select the individuals who will represent the US in world competition. The TIMPA field will be closed to R/C airplane and heli flying from Saturday, July 25, thru Friday, July 31. However, the field will be open to spectators, so if you would like to witness a national rocketry event first hand this will be your best opportunity!  Check out the NARAM 57 web site for more details.


Lithium Battery Safety

Lipo Fire 2Lithium battery safety is a subject that can never be stressed enough, even after all these years of battery progress and an impressive safety record within our hobby. Because you cannot see inside a LiPo there is no way to inspect for internal damage or defects that could eventually ruin your day. Always remember, unlike NiCad and NiMh batteries, LiPo batteries are more sensitive to overcharging. Also, overcharging one or more of the cells during the charging process is possible if you do not properly balance LiPo battery packs. Thankfully, all of today’s quality LiPo chargers are capable of balance charging.

The following are the AMA’s suggestions for safe LiPo battery practices:

  • Store and charge in a fireproof container; never in your model.
  • Charge in a protected area devoid of combustibles. Always stand watch over the charging process. Never leave the charging process unattended.
  • In the event of damage from crashes, etc, carefully remove battery to a safe place for at least a half hour to observe. Physically damaged cells could erupt into flame and after sufficient time, to ensure safety, should be discarded in accordance with the instructions which came with the batteries. Never attempt to charge a cell with physical damage, regardless of how slight.
  • Always use chargers designed for the specific purpose, preferably having a fixed setting for your particular pack. Many fires occur in using selectable/adjustable chargers improperly set. Never attempt to charge Lithium cells with a charger which is not specifically designed for charging Lithium cells. Never use chargers designed for only NiCad/NiMh batteries.
  • Use charging systems that monitor and control the charge state of each cell in the pack. Unbalanced cells can lead to disaster if it permits overcharge of a single cell in the pack. If the batteries show any sign of swelling, discontinue charging and remove them to a safe place outside as they could erupt into flames.
  • Most important: NEVER PLUG IN A BATTERY AND LEAVE IT TO CHARGE UNATTENDED OVERNIGHT. Serious fires have resulted from this practice.
  • Do not attempt to make your own battery packs from individual cells.

2015 AIAA Design Build Fly Contest Results

WinnersThe 2015 AIAA/Cessna Aircraft/Raytheon Missile Systems DBF competition flyoff was held at the TIMPA field the weekend of April 10-12. Sixty-five different teams representing 65 different universities attended the flyoff. In all, over 650 students and faculty were present.  Excellent weather allowed for non-stop flying the whole weekend. Of the 262 official flight attempts, 121 resulted in a successful score with 56 teams achieving a flight score – a new record!  Twenty-three teams successfully completed all three missions.  First place went to the University of Ljubljana from Slovenia, the first time a team from outside the US has won DBF. Second place went to University of CA Irvine and Third place went to Georgia Tech. The Best Paper Award for the highest report score went to Georgia Tech with a score of 98.50.

IMG_2008Another weekend of great weather makes for a spectacular Desert Heat rocket launch. While it got a bit warm during the afternoon, it cooled off nicely for the night launch. This is a spectacle that you have to see! The sights, sounds, and smells approach sensory overload. See the pics on the TIMPA Facebook page (follow the link above).
