Everyone: Based on a few flights in the last two months that had some unusual flight profiles and the fact that I have had request for three more Cert Level 1 attempts I thought this would be a good time to remind everyone of our field restrictions, rocket liability and the Waiver Form we have on-site for all High-Power fliers to sign. As Jim Conn, former prefect of Tripoli, SC, notably said a few years ago: "You are always one flight away from losing your field". Hopefully, we will never experience this nor should any rocket club. So, I challenge each and everyone flying to consider the worst case scenario if your rocket was to suffer a catastrophic failure.
Well, if you live anywhere in the vicinity of Charlotte you had one heck of a thunderstorm last night and we're expecting high winds all day today as this system moves through the area, so NO LAUNCH ON SUNDAY! We are looking to have a make-up day (or 2) NEXT weekend depending on the barley crop height, TBD mid-week by Rocket Ralph and Kip.
Everyone: The waiver is set for 9:00am till 7:00pm Since the winds will be out of the S-SE 5-15, I would set the flight line just past the ditch in the middle of the field. That allows us to see the whole North field for recovery. Brent Johnson from Hobbytown will be there around 10:00AM , SAVE HIM A SPOT UP NEAR THE FLIGHT LINE. Anybody with Walkie Talkies please bring to help in rocket recovery. I have mine. The Auto Fair is at the Lowes Motor Speedway all weekend, folks coming from the I-85 Hwy 29 be ware of extra congestion in the area. You may want to get onto Hwy 49 to I-485 or Hwy 601. I will be out there now by 11:30 as Amanda's game has been moved up. I will take the Batteries, T-shirts and Walkie-Talkies to Roy's in the morning. Thanks, Ralph "RocketRalph" Roberts
Dispatch from Ralph "el Presidente" Roberts, high-flyin' propellent-burnin' man: Yeah, I was the only ROCC member down there Saturday. I gotta rag all of the gang. I had to go down and "Represent", an boy did I, 4 flights totaling over 12,100 feet in altitude. The Flights: The 5.5" Patriot on a DPS 3 Grain 63mm Super Blu Motor - K740+ (Originally calculated to a K993) - 3496' Fear Factor on a DPS 4 Grain 38mm SRB Motor - I440 - 2450+' Sugar Cherry on a DPS 6 Grain 38mm Armageddon Red - J650 - 4604' Fear Factor on a DPS 6 Grain 38mm Yellow Jacket Motor (w/ SRB bumper grain to boost KN) - I200 - 1618' See videos and some pictures courtesy of Tom Binford at the ICBM website: All perfect boost and perfect deployments, they were "OFF THE HOOK!!!!!!!!". And you all rag me about not flying much, at least in O'burg I can play cause I don't have to deal with all the club BS. Sincerely, Ralph "DPS mix propellant rules, Sugar propellants drool!" Roberts Note: I'll come down from my soap box and pull in my chest........ Thanks Ralph !!!!
Everyone: We are going with a Saturday, 14 Apr, one day launch. With the approaching strong Cold Front and rain holding off until late in the day on Saturday, we are going to attempt to fly one day this coming weekend. There will be no camping and with Sunday's wind forecast being too strong, we will scrub Sunday's launch. There was some interest to move the start time up on Saturday, so Roy, Paul, and Wayne can arrive early for setup, say 9:30 am. If the others can join, please advise. Again, I will not make it out until 1:30-2:00 pm. We will not have the NAR contest as winds are forecast to be 5-15 miles per hour and restricted to only one day. Too strong for a productive contest. (you can test fly your rockets for performance though) Depending on the circumstances and availability we will reschedule the contest to next weekend, April 21st and 22nd. However, based on crop height, that may still be moved again. We will discuss Saturday and consult Kip for next weekend. Everything else is pretty much as in the original announcement. (Except most things!-doc r) The ROCC Rocket Raffle will be held at about mid-day on Saturday. Good luck everyone. Thanks, ROCC Prez. PS Mark, Terry the Wildman orders did not ship, hopefully they will be here next week. Feel free to call and discuss. Sorry he was waiting on Aerotech on a motor I ordered.
Everyone: As you all know we moved the launch weekend up one week to beat the crops, flying the 2nd weekend instead of the 3rd. The following below was the announcement I planned at the start of the week, however, as the weekend is approaching the weather forecast is going downhill fast. As of tonight the forecast is Rain and Storms Saturday, Rain and Clearing and Strong Winds Sunday. As it stands tonight and after speaking to Kip and several of the guys. Here is the plan: We will make a GO-NO GO decision Thursday night, rolling the launch to next weekend 21 - 22 April, if we scrub. Now, Kip says we should come out to the field say around next Wednesday next week to check the status of the Barley. The cold snap has kept it from growing much this week, however, it may still be to high to fly, especially small rockets without streamers. As far as vendors for next weekend, I know Ken is going to the Red Glare launch in Maryland, Giant Leap may also have another commitment, and as far as Brent I have not check with him yet. We will just have to see. Again, we have our backs against the wall, weather and crop status. We will have to take the worst of the two evils. Please check email and the website the next couple of days to see what we do. Sorry for the doom and gloom, but we have to go with our best scenario. Thanks, Ralph Roberts ROCC PreZ and Tripoli Prefect. Original launch announcement:
I've gotten a number of E-requests for reminders of 'What's the contest categories again?" From what was in last months launch announcement, we advertised three categories. 1= "D" engine "Streamer Duration". 2= "C" engine "Egg loft Duration" (with a chute) 3= "A" engine "Supra roc Duration" (also with a chute) I got some additional information about the "A" engine "Supperoc" rocket contest category from our NAR contest source, Bob. As follows. For a Supperoc; It needs to be 40" to 60" long, the longer it is, up to 60", the more points you get. You can use any size body tubes you want, naturally the thinner it is the lighter it can be. And, the bigger the tube, the bigger the chute you can pack into it. Check the ROCC web site, WWW.rocketrycarolina.org, for posted plans of a standard Supperoc. You can fly any "A" motor on the NAR Approved motor list. I myself would be quite interested to see someone fly using the Estes A8 or the Quest A6 (both 18mm), to see if that would be an effective strategy. The Egg loft and streamer duration is pretty straightforward. The article on the streamer duration helped out a lot. I'm working on the "D" streamer rocket myself. See everyone on the flight deck. Roy ROCC Sec. & with Regards, Bob Bernatchez
ROCC is flying D Streamer Duration in the contest next month, and I've been asked to provide some tips for winning the event. As a rule of thumb, for any duration event, you want to build the lightest, minimum diameter bird you can, and then put the largest possible recovery device in the rocket. Most often, these goals will conflict, so it will be up to you to make design choices that will gain you optimal performance.
