"Deer John", egh? Did she leave you over your rocket obsession? If so, I'm sure it was totally worth it. That's a good looking launch vehicle.

Deere John

At one time, I had all John Deere equipment and just thought it would be great to have a rocket with the same color scheme.

If you notice the printing on the rocket says nothing Flies like a Deere....

Had the hat before the rocket...

This was allot of fun but expensive... cost around $750 a launch...

$750 a launch? My wife would leave me to...

I don't like to think about how much it costs to fly my little 29mm motors.

I only launched this 3 times, back when I had money....LOL

Now this Rocket is hanging up in a hobby store in North Carolina...

I wish RCG had classified for Rocket Stuff. I have a ton of stuff to sell.

You can always post ot in rocketryforum.com, they have a for sale page, rcgroups does as well, but you'll probably get more interest on the rocketry forum.

FAI Competition Rocket

Here's a photo of a model for FAI S3 competition (Parachute Duration). This was a test flight flown with an Estes A3-4T this summer. The parachute is 44 inches in diameter. Weight of the model is 9 grams.

With a 44" parachute at that weight, I always wondered if those duration rockets ever catch thermals and float back up.

Thermals

Stick,
That is the name of the game! Model rocket duration competitions are won by those who can "pick air" and launch when a thermal is coming by. In competition this year I had a flight of over 21 minutes. That flight the model went up several times in thermal lift before finally landing.

That looks like an interesting competition class. At least the flight is not over in a flash.

@ Richard; No that is empty weight. The 'chute is made from 0.31 mil plastic sold widely in the US as drop-cloth material. I don't know the weight of the chute, but I'd guess it adds 3 to 5 grams.

@ Trisquire; FAI competition events are all multi-round. For Parachute Duration, with "A" motors (2.5N/s), the flights have a 5 minute max. For Helicopter and Streamer Duration, they have a 3 minute max for the 2.5 Newton / Second class. I cannot remember the max for Boost-glider, but I think it might be 5 minutes as well. In all the events, 3 rounds have to be flown using 2 models, so you really have to have a team help you get them back!

The World Championships start 1 September 2012 in Slovakia. I can't wait!

Thats what I suspected well that or mylar. The red and the black look like markers but what did you use for the white? [The drop cloth plastic around here is all clear] 16 shroud lines cool!

Wish you luck and good thermals.

Correct, the red and black are super-wide markers. The plastic is HDPE and comes with a matte finish, not the glossy finish usual with LDPE plastics. I use talc (baby powder) to keep the parachute from sticking when packed in the model. The talc makes the black appear a bit grey, and the clear matte plastic appears a bright white in sun-light.

Cheers,
Terrill
