Maddox Dairy Farms - Helm, CA


Here's one you shouldn't miss!

LDRS is the premier annual rocketry event for the Tripoli Rocketry Association (TRA). For 2018, LDRS 37 will be hosted by Tripoli Central California (TCC) at the Maddox Dairy Farms in Central California.

The Maddox Dairy Farm launch site provides over 20 square miles of flat, open, agricultural land for recovery. The Central California weather is (almost always!) good for flying. Our waiver is 17,000 feet MSL (16,800 feet AGL). We can fly individual motors up to a maximum impulse of M and complex rockets with a combined total impulse of up to N. And TCC offers some of the best high-power launch equipment anywhere, including an away cell capable of launching rockets in excess of 250 pounds!

Excellent rocketry vendors will be on site. We have arranged for a first-rate restaurant to host the TRA Banquet on Friday, May 18. And you won’t want to miss the night launch and live band on Saturday, May 19 as well as other special events throughout the week. Come join us for 5 days of launches from May 16 through May 20!

There is a night launch scheduled for Saturday night, a Nike Drag race and other special events like the LDRS Banquet a Harris Ranch. There will be onsite food and rocketry vendors. Free Camping on site with hotels available in the area and a nearby corner store at the Helm crossroad.

We'll continue to post updates to this event as we get them, but you shoul check out the official website at https://ldrs37.org for all the details. This is the earliest I think I've ever seen an LDRS and the temerature and weather should be great!  If you haven't attended an LDRS, you should definitely consider attending this one.
