| I ran across a site that has all kinds of calculators relating to aviation. And many other uses. Just for instance click the link below and put in a temperature and speed and hit calculate. http://www.csgnetwork.com/machonecalc.html I also have obtained some tracking gear. This is stuff I used when hunting with hounds. I was able to track a ground running dog from Franklin to West Swanton @ 12 miles. Should be amazing in the air, I don't think we could out launch it. The transmitter was sealed in a collar. I dremeled it our last night. It is about the size of an andes thin mint and weighs 1/2 ounce. I am thinking it could also be up for use to club members. Or if they get their own transmitter could borrow the receiver. The transmitters run about 130 bucks. The receiver is about 600. Unfortunately we are still trying to remember where we put it. |

| Here is a link some friends sent me regarding high altitude ballons and data transmission. This was done in southern vermont to 107,000 feet. Very cool video footage. www.vermontscience.org/ |

| Uh, oh. Next launch is on the first weekend of deer season. I could still get the pads down and picked back up though I think. Will see what develops. | |

| Sunday, October 19, 10:00am to about 2:00pm will be the Champlain Region Model Rocket Club (CRMRC) launch in a field off Maquam Shore Road in St. Albans Bay, VT. The launch will be conducted in accordance with the National Association of Rocketry (NAR) safety rules, allowing flights up to 10,000 feet. Anyone is welcome to join us, either to watch or fly your own rockets. Club members have plans for several high power flights: a 60 pound rocket to 6000 feet, two different 15-20 pound rockets to 4000 feet and over a dozen 3-10 pound rockets to between 1000-3000 feet. While we get excited to watch these big projects fly, we get just as excited to watch Estes rockets fly too. Additionally, since it is October, you can expect to see some odd empty plastic beer bottles taking to the sky to celebrate Octoberfest (empty is the key word, as no alcohol is allowed on the field). For you rocket scientist nerds, here is something to ponder (the rest of you can read this paragraph if you want). How much energy is required to make a 60 pound rocket go to 6000 feet in 20 seconds, with the rocket standing still at the start, then 5 seconds of acceleration, and then 15 seconds of coasting back to a velocity of 0 due to gravity and air resistance? Think about how much power is released in that five seconds. What do you estimate the maximum speed to be? If I guess it to be 400MPH -- so the rocket goes from 0-400MPH in 5 seconds, and then 400-0 in 15 seconds. Imagine the G forces. For you non-rocket scientists, think about it this way -- stack 4 men's bowling balls on top of each other and then throw all four at once to a height of 6000 feet. Then get out of the way as they come down. The field can be reached from downtown St. Albans by going out Lake Street, past St. Albans Bay State Park onto Maquam Shore Road for about 1.2 miles beyond the traffic circle. Parking is on the right where the CRMRC sign will be. The farmer has given us permission to drive out on to the field and park so no one will need to walk too far between their car and the launch (of course, the closer you park the more you risk having a rocket land on your car). Please drive slowly on the field. The weather is predicted to be sunny with highs in the mid-50s and a light 6MPH wind. This should allow anyone who wants to fly high to do so. Fliers and spectators should dress for the weather and bring something to sit on. A limited amount of shade will be available. Expect to spend a couple of hours in a field so bring whatever you think you will need. The club has many model rocket kits and motors which will be available for purchase on the field at significant discount. If you buy a kit, it will include the a motor if you return to a CRMRC launch to fly it. Additionally, we have parachute protection which you can use for free. To top it off, we have hundreds of motors at either $1.00 or $1.25 each. If you have never seen a high power launch, this is a great chance to see several high power flights. All of the club members are enthusiastic. So if you have any questions or want to see what is involved to fly model, medium or high power rockets, do not hesitate to watch and ask questions. Any launch requires the weather to cooperate. Please check the CRMRC web site (www.crmrc.org) or call my house to get up to the minute status. If you have questions, feel free to contact me via email or phone. Otherwise, I hope to see all of you on Sunday. |

| Yee-ha. Maybe. I mean, I have some motor tests I need to do for a manufacturer, and those sort of take priority. I'll certainly be boosting Gas Guzzler on a 75% K525, and hope to loft the Doctor. Beyond that I'm pretty much wide open. Kevin |

| Hey Kevin, Wanna race my Talon with Bluemoon at the October launch. I think a K race would be fun, hybrid versus apcp. I promise to wait for your tanks to fill. We can race for pinks. Of course I may have to give Howie your motor if I don't get a case by then. LOL |

| Saturday, September 20, 10:00am to about 2:00pm will be the Champlain Region Model Rocket Club (CRMRC) launch in a field off Maquam Shore Road in St. Albans Bay, VT. Kids from 8 to 80 are welcome to watch or bring a rocket and join us in flying. The launch will be conducted in accordance with the National Association of Rocketry (NAR) safety rules, allowing flights up to 10,000 feet. Model rocket (1/8A-E motor), mid-power (F-G motor), and high power (H-M motor) rocket flights are planned. If you have never seen a high power launch, these is never a better time. The field can be reached from downtown St. Albans by going out Lake Street, past St. Albans Bay State Park onto Maquam Shore Road for about 1.2 miles beyond the traffic circle. Parking is on the right where the CRMRC sign will be. The farmer has given us permission to drive out on to the field and park so no one will need to walk too far between their car and the launch (of course, the closer you park the more you risk having a rocket land on your car). The weather is predicted to be warm and sunny with an 11 MPH wind, so plan accordingly (hat, sunglasses, sunscreen, drink). As of today, the grass is about six inches tall, so this is perfect for smaller rockets (soft enough to land on but not be lost in it). The launch is the middle of a field, so bring chairs to sit on and do not expect any facilities. A limited amount of shade will be available. The club has many model rocket kits and motors which will be available for purchase on the field at significant discount. If you buy a kit, it will include the a motor if you return to a CRMRC launch to fly it. Additionally, we have parachute protection which you can use for free. To top it off, we have hundreds of motors at either $1.00 or $1.25 each. If you have never seen a high power launch, this is a great chance to see several high power flights. All of the club members are enthusiastic. So if you have any questions or want to see what is involved to fly model, medium or high power rockets, do not hesitate to watch and ask questions. The field is relatively dry with occasional wet spots. The weather between now and the launch is predicted to be scattered thunderstorms. If the field gets drenched between now and the launch, then the launch will be scrubbed. Please check the CRMRC web site (www.crmrc.org) or call my house to get up to the minute status. The club is planning to set up 1/8, 3/16, 1/4 rods along with 3 foot, 6 foot and 8 foot standard rails. If you need something other than that to launch your rockets, please let me know. If you have questions, feel free to contact me via email or phone. Otherwise, I hope to see all of you on Saturday. |

| So the Talon is in the final stages of construction. Hardware odds and ends. Has had complete primer done now from top to bottom sanded down and done again. The question is to wrap or not to wrap. The shop said "hell lets wrap it if you don't like it we can squirt it." I said "whos gonna pay for that." Yet to be determined. Well I don't quite think it is sexy but it is looking good.  |
