Effective December 31, 2018, I will be stepping down as Prefect for Tripoli Mid-Ohio. Elections were held at our December 8 launch and Todd Knight was elected prefect. The remaining board/staff will remain unchanged. In order to ensure a smooth transition, I will stay on staff as the President of TMO.


I was the second prefect for TMO after Ross Dunton sold Magnum Rockets; besides Ross and me, the only other prefects have been Mark Mazzon and Kreig Williams. Both of these fine men are no longer active in the hobby.


Since I came into the hobby in the mid-1990s, Tripoli Mid-Ohio has seen a lot of changes, not all of them for the good:


• Ross Dunton moved his shop from outside of Mechanicsburg to downtown Mechanicsburg
• Ross Dunton sold Magnum Rockets.
• We have lost fields.
• We have found fields.
• We have lost fields; again.
• We have lost members due to death, lack of interest, club politics, and differences between members.
• We have gone through more launch systems than I care to think about. The Wilson F/X wireless has found a home with us.
• We have partnered with Tripoli Gerlach to provide the Wilson F/X wireless system for all the BALLS launches.
• We support local schools, colleges and universities.
• We have members that are deeply involve with The Ohio State University’s “Buckeye Space Launch Initiative” and it shows with their successes at Spaceport.
• We are still launching rockets.


We are still here. While I wish I could take credit for the fact that we just won’t go away, the reality is that the members have always stepped up to help out in many ways. Just a few examples are:


When the launch system we had prior to the Wilson F/X was on its last legs, a handful of members donated the funds to purchase the Wilson system. When we decided to go wireless, a handful of members literally dug into their pockets and threw cash at the problem.


We have members that update the launch gear and keep it operating smoothly, in many making improvements for reliability and safety out of their own pockets.


We are slowly but surely updating our infrastructure with new pads and other essentials.


Our two land owners, Chuck Wildman and Marty Spears believe in what we do and support us enthusiastically. We in turn do everything we can to ensure that the relationship remains positive.


Tripoli Mid-Ohio will never be a huge club with dozens of members and I am okay with that. We are and remain a tight-knit little band of crazy amateur rocket scientists. W are in this to be safe, have fun, and promote the hobby.


Todd Knight will be a damn fine prefect. He loves the hobby and the folks that participate in it. As an engineer, business owner, and mentor for the fine students at Ohio State, he brings that certain level of dedication to the role. Please join me in welcoming Todd as prefect.


SYATNL!

Thanks to Bob Mcaninch for the video of Super Batray launch! :-)


Sorry for the lack of videos, but since my hands were so cold, I wasn't able to take a lot of videos that turned out to be somewhat steady.


Also, I would like to thank everyone for helping me prep and fly the Super Batray! I very much appreciate it! I plan to come back in the spring and fly it again, this time dual deploy!




Thanks,

What a great day for a rocket launch! Cold? Yes, it was, but the skies were clear, and the wind were light. If you missed launching with on December 8, you missed one of the BEST launch days we have had in a long time. We witnessed everything from C6-5 to the mighty Aerotech M1315W; and Research motors in colors of red, white, and blue.


Seth Cooper from Athens came to fly rockets and fly rockets he did! Set was accompanied by his brother Matt, and we are hoping that the HPR bug bites Matt. Seth’s flights:


•   Mad Cow “Stinger” on a 75mm AT K780R
•   LOC “Mega Mag” on a 54mm CTI J449 Blue
•   Mad Cow 5.5” “Pike” on a 75mm AT M1315W
•   4” “Nike Smoke” on a 38mm AT  I600R
•   Mad Cow “Seawolf” on a 38mm AT I300T


Seth also used his drone to pin point the location of his “Stinger” after it landed to determine whether or not he needed to cross over the creak that borders the south end of our field. What a great use of technology!


Andrew Kleinhenz made the trip from Bowling Green to put his fleet airborne:


•   Mad Cow “Big Fizz”, the Estes upscaled Alpha on an AR H180W
•   4” “Aries” on a 38mm AT 38mm I211W
•   3” “Orion” on a 38mm I200W


Andrew has become a master at using the Jolly Logic Chute release and never fails to provide coaching on it s use to flyers at the field.


Jim Rosmarin brought daughter Lucy along as flight support for his two flights:


•   LOC “Big Nuke 3E” on a 54mm AT J800T
•   Scratch-built 4” “Tie Die Confetti” on a 38mm AT J350W


Both flights were excellent with nominal recoveries.


Bert Garrison had three great flights for the day:




•   4” Public Enemy “Ultra Fat Boy” on a Loki I-110-9 for a slow and majestic flight to 1398 feet AGL. The ejection event sent the airframe through the center of the chute and the rocket fell back to earth and stuck the nose cone. The only damage sustained was to the telemetry mount in the nose, which was quickly repaired with some 5 minute epoxy.
•   4” Public Enemy “Ultra Fat Boy” for a TRA L2 certification flight on a 38mm Loki J712 Loki Blue for a screaming and successful L2 flight to 5080 feet AGL. 
•   Public Enemy “Performer” on a 38mm AT I200W.


We do not see that many Loki motors and we are hoping se see many more, as Scott Kormeier makes some awesome propellant.
Doug Peterson made the hour-long trek down from Plain City, only to return home to retrieve additional trackers when the one he brought went into unhappy mode. Doug had two great flights:


•   3” Wildman “Punisher” on a 54mm Research K477 Wayside White producing 1525 ns of smoke and fun. Rocket turned in a spectacular flight to 8895 feet AGL and was recovered a few hundred feet off the flight line. So much for needing that tracker.
•   3” scratch-built “Aerobee Hi” named Kenny II. Doug killed Kenny a few launches ago. Kenny II went to over 4000 feet on a 38mm Research J605producing 828 ns. Kenny broke a fin on landing but otherwise survived.


Martin Quanci from Chillicothe launched his highly modified LOC “EZI-65” on a 38mm AT J340 Metalstorm for a nice flight and recovery. A HUGE Thank You to Martin and the WV SOAR for loaning us their wireless PA system. I think we will be purchasing one of these next year. It is great to see NAR and TRA clubs playing nice.


Welcome Gerald Powell from Hillsboro! Gerald flew his Estes “Max Trax” on a C6-5 for the sole LPR flight of the day. I think he likes us, as he hung out through the end of eh launch and helped with tear down.  Please come back and fly with us when we resume operations in March and let us know how we can help you move up the cert ladder.


Bob McAninch, TMO’s IT guru and secretary/treasurer launched his “URSA Major” for the one-millionth time for a nice flight & nominal recovery on a Research J426 Wimpy red. Okay, maybe that is a bit of an exaggeration, but he has flogged this rocket many, many time. We are looking for something new and exciting from Bob in the spring.


David Sears from Kent showed up late but eager to fly. David launched his 4” Wildman “Darkstar” on a 54mm Gary Dickinson L1144 Mad River Blue Research motor to 8800 feet and change AGL. Recover was a short walk from the flight line.


Lat flight of the day was by Gary Dickinson and Andrew Bissonnette launching Andrew’s Mad Cow “Super Bat Ray” on a 38mm AT I284W. Andrew was experiencing issues with everything from a liner that did not want to go into the motor case to issues with shear pins. The Tripoli Mid-Ohio faithful jumped right in to help Andrew get his rocket ready. The motor refused to light multiple times, but finally sprang to life with a pair of dipped e-matches and the rocket zoomed skyward for an excellent way to end the 2017/2017 launch season.


We are done launching until March 2019 unless we get some really nice weather. Until then, ger busy building those rockets and we will See You At The Next Launch!

We are "GO" for launch this Saturday 12-08-2018. I am not sure what our cloud deck will be so we will address this the day of the launch. It is going to be cold, so dress accordingly. This will be our final launch of 2018 and we will be back on the field in early March, weather permitting. If we get "reasonable" weather in January & February will will schedule something.



Lee Berry & Merlin Missiles will not be attending this launch, as he is out of town on business.



For 2019, it looks like we will not have Lee at any of our launches, as he will be supporting WSR. As in the past, if you need something, please let Lee know and we will be sure it is available for you at the launch.

Ordered quart each of 'Glass Bubbles' and 'Phenolic microballons' from US Composites.  Smallest size they had.   One of those should do the trick.

Bondo is a polyester base rather than epoxy. I've had problems with it flaking off. I use glass microballoons in epoxy, easier to sand. My brother uses fumed silica (cab-o-sil) harder to sand. +1 for us composites! They have good prices and package smaller amounts for those of us who are'nt building entire sailboats.

Anyone have recommendations for filler to use when filling 6oz fiberglass weave?

I tried a two part bondo filler several years back, and remember sanding more/harder than i anticipated.  Might have been good amount of fumes as well, which i would like to avoid.

Leaning towards glass or phenolic balloons from us composites, but i have not tried any epoxy fillers yet.  Already have 635 epoxy resin/hardener.

My personal guideline is based more on airframe diameter & motor size, and not rocket weight. A 4 inch diameter rocket with an M class motor is about my limit for 1010 rails. As previously mentioned, the new back-to-back rail mounting will not automatically send to the away cell.

I have been using 1010 buttons on a 10 1/2 lb rocket for quite a while with no issues. The way the rails are set up back to back now, going to 1515 buttons doesn’t mean a walk to the far pads, so either should be ok. I don’t know if theres a rule of thumb for going from 1010 to 1515 buttons, but I’m sure one of our more experienced flyers would know.

Does the TMO/members have any preferences for when to start using 1515 rail buttons?  Working on a 10 lb rocket.  Currently assuming 1010 buttons will be fine.
