I need to reduce the size of my build pile and have two kits for sale:

Wildman Jumbo Jart. 8" diameter, dual deploy, 98mm MMT. $500; this is less than the Wildman club price!

Wildman 5" Jart. 54mm MMT. Easily changed to 75mm id you want to be a true Wild Man! $175.

I can and will deliver these to the TMO site and can deliver within a 50 mile radius of Dayton Ohio. Cash and PayPal "Friends & Family" only. No checks, trades, first born, etc.  ;D

Tripoli Mid-Ohio #31 got a break in the weather and we were able to hold our inaugural launch of the 2017/2018 season. The temps were cold starting out and the winds were brisk, but that did not stop the faithful from coming out and burning some AP at the “Standing Oaks Farm” launch complex under cloudless blue skies. We had eight fliers with a total of fifteen flight between them.

Prolific flier of the day goes to Seth Coop from Athens. He had a total of four flights:

•   MAC performance Scorpion – Loki I405
•   Polecat Goblin – AT J275
•   Nike Smoke – AT J350
•   Madcow Stinger –  AT K695

Tim Mauk had two great flights:

•   Estes Leviathan – AT G53-7
•   LOC/Precision Stovi – AT G74-6

Andrew Kleinhenz from Bowling Green had two nominal flights:

•   Madcow Frenzy – AT I200-7
•   Super 200 scratch-built – H180

Jim Rosmarin from Dublin flew his quarter-scale PML Patriot on an AT I200.

Andrew Bissonnette from Cincinnati abused his Estes Partizon on an AT G75 Metalstorm. After repairing the rocket due to a fouled chute and a very hard landing, he came back and absolutely spanked the somewhat shorter Partizon on a CTI G106 Skidmark. He and brother Patrick had a very long walk to recover the bird. Andrew also had a scratch-built flying saucer that did not launch due to a burnt igniter.

We can always count on Doug Peterson to represent the TRA Research community when he shows up. Doug launched his scratch-built upscale Estes Corkscrew apply named “Clifton Junior” on an I130 Pitch Black motor for a wonderful spinning flight. He came back and flew his scratch-built Aerobee named “Kenny” on a J360 Wayside White for a great flight and a long recovery walk.

Congratulations go out to Adam Grubb from Columbus for re-entering the HPR community with a successful flight of his scratch-built “Déjà Vu” on an AT H180. Adam and his dad Joe (Assistant Prefect & fellow TAP Member) are very involved in the RC airplane hobby. We are looking forward to Adam advancing in HPR and possibly bringing a rocket glider to our field when we get a calm day.

Congratulations also go out to James Dai, John Titus, Nic Flesher, and the rest of The Ohio Sate University “Buckeye Space Launch Initiative” for a successful launch & recovery of their two-stage project. Their rocket named “2 Pac” boosted on an AT J350, staging to an AT H153. The recovery team had a very long walk to recover the sustainer! According to advisor Todd Knight, this is the ‘proof of principle’ project for an upcoming 100K flight.

Kelvin & Mel McMillan brought the Magnum Rockets “Big Purple” to the field in order to have a couple of folks to assess the extent of repairs required to make this classic flyable. This rocket was formally owned by Ross Dunton and is an impressive 11.5” in diameter, 15 feet long, and weights around 100 pounds fully loaded! Look for this beast to make an appearance at the 2018 Phil Prior Memorial Launch. Ross did the design; the late Kevin Goraj built & painted the project; and the late Dr. Phil Prior handled the electronics & recovery.

That’s all folks! Thanks to everyone who showed up to fly and help with range set up & tear down. SYATNL…….

The launch on Saturday is a "GO". Setup around 9 AM and the range will be open from 10 AM to 4 PM. It will be cold so dress appropriately.

From Scott at Loki Research:

It’s time for me to order more 76mm tubing again and make more hardware. I’ve had a few requests in previous months about making a long 76mm case so I considered doing a small run of ~57” long cases. These can be used for very high performance reloads, or as mandrels for making your own custom made composite airframes, or for both. They will be type 3 hardcoat plated the same as all of the latest Loki hardware has been.

This is quite possibly your only chance to get tubing in a 75/76mm motor case of this high of quality, at this long of a length with the straightest tubing you can have made in this size. Tubing specifications are called out by ID and wall so the OD is only a reference which is 2.985”. The ID tolerance is +/-.007” IR and the wall is +/-.006” IR. IR stands for individual reading. This means that for every inspection reading location, it has to be within those tolerances. Most tubing tolerances are twice this amount, and they are for the average tolerance of all location readings, not individual readings. After measuring the OD on the entire length of a few current 76/8000 cases on hand, I found a maximum OD variance of only +/-.0025”. That is outstanding!

I would like to get a minimum of about 10 cases or so to make them as cost effective as possible, otherwise the anodizing cost would be relatively high for only doing a few. If I get less than 10 orders, I’ll see if I can still make it work.

Pricing will be set at $355 for the hardcoat finished case only with a low profile thrust ring.
Complete hardware with the addition of snap rings, nozzle washer, bulkhead and nozzle will be priced at $485.

These prices are very reasonable in my opinion if you compare them to the gold type 2 anodized 75/10000 (55.7”) Kosdon hardware pricing from 2000. At only a 10% increase for either the case with no thrust ring or for the complete hardware, that’s not bad at all for 17 years of inflation! Compare this with other current brands and it is still an excellent value.

Please note that graphite nozzles will not be warrantied for any reason. They are normally only good for one use in cases this long anyway. Also, I would highly recommended that nothing less than Loki Research X grade liner sets be used with this hardware. If you want a set of liners and casting tubes for your hardware, I will include plenty enough of X grade liner and casting tube material for you to cast a motor for only $50. Using standard 76mm Loki internal components you will have at most 52.125” of propellant length using a standard Loki graphite nozzle.

If you would like to purchase one of the above, please send me an email with everything you would like by Dec. 18th.
In the subject line you must put 76/13000 Purchase or it may be missed if it gets filtered into junk mail. Send it to scott (AT) Loki Research –DOT- com… without all the extra stuff. Please post this to your local EX boards/forums as well. All purchase requests need to be received no later than Monday December 18th. I’m sorry for the short notice as well but better late than never. You will be charged 50% upon order acceptance once I have enough orders and 50% plus shipping at the time of delivery. Delivery is estimated to be by the end of March.

For those wondering if I will be making reloads for these, for now the answer is no, so don't purchase one for that reason. However I would make myself a case or two so I have something to do testing with if time permits.

PS. please no PMs about this here but feel free to email this to your friend and re-post it on any local message boards.

Disclaimer- if you purchase one in order to make your own reload, buyer assumes all risks. I assume you should know what you are doing.

The BoD has met and we are scrubbing the 12/09 launch and rescheduling it for 12/16. I know that this is in conflict with the fine group at WSR, but all of us will have to deal with it. Merlin Missiles will not be at this launch, so if you need anything, contact Lee and I will see that it gets to the field.Here's hoping for good weather.....

It is with a heavy heart and a soggy attitude that I must announce that the Tripoli Mid Ohio launch scheduled for this week end has been scrubbed. Rain on Saturday and high winds on Sunday do not offer us positive conditions. Hopefully we will get a break soon. The next launch is December 9, 2017.
