A Message from the Prefect and President

To: All Certifying Fliers coming to LDRS 37

From: TCC Prefect Bruce Rohn and President James Dougherty


We are pleased to host you at our first ever LDRS event! We hope you enjoy your flight experiences during your time with us. To assist us in helping you complete your certification success, we have a few suggestions to pass onto you.

Documentation- All supporting documentation that you bring with you to the Launch will really help us. When you became Tripoli members, unless it was very recently, you should have received your Tripoli Membership Handbook. Inside the Handbook at the front will be your Tripoli Rocketry Association Member Certification Form. This will have your TRA Number, your name and address and it will have spaces for the Prefect to fill out when you successfully certify for all Levels 1 to 3, including when you pass your Level 2 written exam. This shows your past cert activity. Your current Tripoli Membership Card will have your current Certification Status, even if it is Level “0”. If you became a Tripoli Member recently, then a copy of an email showing membership payment to Tripoli will suffice (even is you have no Membership Number assigned). Please also bring any proof that you already passed your Level 2 exam, so we won’t have to make you take it again at our Launch before we let you attempt your Level 2 cert flight.

Certification Requirements – You will be expected to know what the certification requirements are when attending our Launches. You can find these requirements at the Tripoli rocketry Association Website, and our Tripoli Central California Website. In addition, our president James Dougherty will conduct Fliers Meetings at the beginning of the Launch. These meetings are mandatory. At these meetings we will review Safety Code Rules to follow and particular things to keep in mind regarding the property on which we Launch.

You can always come to the Prefect/Certification Tent to ask questions and get information about Certification.

A word about Recovery Systems used – Whatever approved recovery system you use for your certification flight, our policy is that the entire recovery system must work as designed. This means if electronics are to be used to deploy the parachute, then it must work as designed. If you are using Dual Deployment as the recovery system for you Certification Flight, then both the Drogue and the Main must deploy for successful certification. This is a safety issue! Rockets descending fast because the drogue failed to open, even if the main deployed, can be a danger to persons or property when striking the ground. Cert flights where one component of the recovery system failed to work, even if the rocket is recovered intact, will not be certified.

Presentation of your rocket– We want to inspect your rocket for your certification flight, both before your flight to ensure it can fly safely, and after the flight to ensure it did not sustain excessive damage that would make it unsafe to fly again. We make every attempt to watch the rocket all during its flight, in the case it cannot be recovered from loss, to ensure it stayed together and intact during its flight.

Thank you all for your great support and see you at LDRS!

Bruce Brohn, Prefect

James Dougherty, President

AMW/PROX – LDRS Special Events and new products!

LDRS Poker Contest

There are 5 participating vendors who have donated to this contest. With the purchase of an item from each of these vendors the first 50 fliers will receive a playing card. To prevent swapping of cards amongst fliers the cards will be dated and signed by the flier and vendor. Collect all 5 cards for that date from each of the 5 vendors. At the fliers meeting, the next morning, the flier with the highest poker hand will receive a prize from the pool of donations! In the event of a tie the fliers will draw a card from a deck and high card wins. Save your cards from the weekend and the person who has collected all days that can make the largest hand from his cards wins a special prize!!


We will be bringing along the newest member of the Zoo – “ The Scalded Tiger “

We will also have the New Baby Red Max, a cute 2.2” diameter fiberglass kit.

And for those who prefer “Cardboard Kits” we have brought out a 4in Red Max with 0.25 plywood fins.

Cannot make NSL? Then pick up your commemorative NSL Kit at LDRS for the special price of $39.95 WOW!!

Also be sure to stop by early and pickup your White Thunder and C-Star motors from CTI while they last. THEY’RE BACK!!

LDRS Registration/Event Badges

If you registered online before the cut-off period, you’ll get your own fully personalized badge generated from the Gecos information which was captured when you created your account on this website. We’ve made a few changes to the badges we’re using this year at LDRS37, we’ve selected Duracard as our vendor and decided to go with a standard 3×4 lanyard-punched badge. These will be a high-quality 10mil Teslin full-color print with 10mil lamination on both sides, printed double sided. We’ve also added a digital signature and a QR-Code which fully encodes a VCARD 4.0 contact – it includes your Name, Email address, TRA/NAR and Level and will allow you to input a phone number before adding as a contact to your Mobile phone. Please install QRReader (by TapMedia) to process the QR Codes (available for both Android and iPhone) – there are a number of apps you could also use but the above were tested at 10cm scan distance with both iPhone 6 and Google Pixel.

A custom Tripoli Central California lanyard will also be included in your Registration package.

APE Mass Monkey Loft Contest at LDRS 37!

Attebery Performance Engineering is proud to bring the APE Mass Monkey Loft to LDRS 37!


That’s one giant leap for Monkeykind!

  • The APE Mass Monkey Loft is a drag-race style mass launch of monkeys flown in large diameter rockets, and it includes a spot-landing competition.
  • A banana landing target will be placed in the field, and the monkey that lands closest to the banana in each heat will win an Attebery Performance Engineering Head End Altimeter Bay for 7.5″ Nose Cones.
  • Monkeys must return safely to earth on a separate parachute from the rocket.
  • There will be two heats, one for H class motors, and one for I class motors. And there will two winners, one for each heat.
  • The APE Monkey Loft will be held on Friday, May 18, at 1pm.

Get Your Free Monkey!

Everyone who signs up for the APE Mass Monkey Loft on the sign-up sheet below will receive a free monkey at the APE vendor table at LDRS 37. (Limit 12)

For your planning purposes, these monkeys measure 18” from fingertip to toe and weigh 5.8 oz. Monkeys are known for flexibility, and these can easily be folded into a ball and wrapped in a fireproof chute protector to form a monkey burrito that is about 9” long and fits easily into a 7.5” airframe. You provide the parachute (18” – 24” recommended), chute protector (18” works well), chute release (if desired), large-diameter monkey-lofting rocket (7.5” diameter recommended), and H or I class motor.

H and I Motor Limit

To allow the mass launch to be conducted on the closest bank of high-power pads, the APE Mass Monkey Loft will be limited to H and I motors. There will be two heats, one for H motors, and one for I motors, and there will be a prize awarded for each heat.

Flying a large diameter rocket on H and I motors can result in some very low flights, which is exactly what monkeys prefer, and is what is recommended for the Mass Monkey Loft. Aim for flights between 600 and 1,000 feet for the best monkey viewing, simulate your ejection charge delay timing accordingly, and pick motors carefully to ensure adequate thrust and speed off the rail.

Some examples of high-thrust, and relatively low-impulse motors you might consider are CTI H295, H340, H399, I345, or AT H283, H550, I300, I357. These are just some of the examples that may provide safe, low flights, depending on the weight and size of your rocket, and there are other options as well. Choose wisely!

Note: Please know the exact total impulse of your motor at the time of the launch so that we can show that the total combined impulse of all the rockets in the Monkey Loft complies with the limits for a drag race complex launch.

Monkey Loft Sign Up

The Monkey loft is divided into two heats, one for H motors and one for I motors.

Note: Due to rules governing drag race complex launches, we may launch four full I motors simultaneously from the 300’ bank of high-power pads. And if the motors are smaller than full I motors, we may be able to launch more in one drag race, up to as many as seven I motors simultaneously, depending on the total combined impulse of all the motors. For this reason, we have four positions in the I motor heat designated as the first salvo, and four positions designated as the second salvo. Depending on the number of fliers and the motors selected we may be able to launch the I heat in one salvo, or we may need to break it into two salvos.

Sign up below. Pick up your free monkey at the APE vendor table at LDRS 37. And get ready for monkeys to fly out of your rocket!


[sign_up_sheet ID=’12’]


Monkey-Flying Tips

To give your monkey a fun free-fall and dramatic chute deployment, you may want to use a Chute Release:

To keep your monkey and his chute safe from ejection charges, you may want to use an additional large chute protector, separate from the one used to protect your rocket’s parachute:

The monkey wrapped in a chute protector fits easily into a 7.5” airframe, like those used in rockets such as the LOC Warlock or Doorknob. When the monkey’s chute protector is attached to the shock cord, it helps to pull the monkey out of the airframe when the rocket’s chute is deployed:

Good luck, monkeys!
