Hey guys, (SOS) So recently our team had started up a TARC club out of thin air and have only been designing our rocket for two weeks. Qualification flights are also in two weeks... and we're on a crunch. So far with the zero experience that we have we dove headfirst into a bunch of tutorials on...

Our TARC team recently finished qual flights and are pretty confident that we will make the cut for nationals. We want to start test flying soon. Unfortunately, we ran out of motors and were going to place an order for the E28-7T motors on Apogee, where we usually shop. Unfortunately, Apogee is...

CMASS will be holding the first of three scheduled ARC launches at the School Street Field in Acton on 09 March. The intention of these events is to give local ARC teams the opportunity to make practice and qualifying launches with the required NAR oversight for the qualifying flights. If your...

Hi all, For the past 3 years I’ve been doing TARC with my high school and this is the only year where I’ve experienced this problem. Seems like my rocket has a slight corkscrew or wobble a little after it leaves the pad, only launched it 3 times as this was our first TARC launch of the year but...

CMASS has scheduled a series of four TARC-only launches at the School Street Field in Acton, MA, for any teams that need the space to practice or witnesses for qualifying attempts. The dates are: 18 February 04 &18 March 01 April These are not open club launches but any club members (especially...

Hello, I am new to designing model rockets and while designing one for a TARC challenge, my rocket weathercocks a large amount even though I have a low margin (0.6) and the wind speed in RockSim 10 is only slightly breezy (8-14 mph). The launch guide length that I am using is 8 feet and I am...

Hello everyone! I am part of a TARC team located in Edgewater, Maryland. In one of our test flights, the nose cone became detached from the rocket along with the altimeter, and we lost the altimeter. The final qualification flights are due on April 4th, and we are unsure if we can get an...

Hello everyone! I am new to this forum, so please excuse any ignorance. Our TARC team launched recently with an Ecnojet F20-7W, and we made it to 927 feet at apogee. The flight was an overall success. However, there was concerning stability issues off the launch rod (96 inches). The Rocket...

It’s January and Winter Follies time is upon us. I hope everyone had a good and safe holiday season. Sunday will be a little warmer but Saturday will have sunshine and that should feel pretty good. The Follies are a bit less formal than our regular launches so you won't need to fill out flight...

I designed a rocket and put it into Rocksim, I'm using the F35W-5 motor for this rocket. It is 31.5in with a 3 in diameter and weighs 665g fully loaded with the motor and the payload. When I let Rocksim calculate the Cd it simulates the rocket going 887.25ft. However, when I actually launched...

New build underway

Hi everyone, I'm leading a TARC team for the first time this year and I had a few questions. 1. We are using OpenRocket to model the rocket and everything looks fine but the flight time looks a little unrealistic. We are using two body tubes and the weight of the rocket is around 300g right...

We are a first year TARC team and we are running extremely late on the timing front. It turns out that our faculty adviser had not purchased the correct altimeter and therefore we cannot qualify. Does anyone happen to have a PerfectFlite Altimeter (Pnut, APRA or Firefly) that is somewhat near...

The Central Massachusetts Spacemodeling Society will be hosting three special launches to give TARC teams a chance to do practice or qualifying flights or to hone their skills ahead of the deadline for submitting your scores. The dates are: 23 February 23 March and 06 April. The launches will...

Hi Rocketry Forum, In April I will be competing in TARC, and for those that don't know, this year the goal of the competition is to launch three eggs as close to 856 ft as possible and then recover the eggs with a total flight time of 43-46 seconds. You can find the full rules here. Although I...
