Description

Getting this rocket ready for the next Bunnell Launch at the new field. I hope sparkies are allowed because this rocket needs a skidmark to launch. Also having another rocket ready in case sparkies are NOT allowed !. Selected motor = J250 SK 2 grain !

Update 08/16/2019 - Made already the charges (4) for this rocket, will be flying with an 82 feet streamer to around 2000 feet!

Update 08/17/2019 - Loaded the rocket with the drogue charge in a dog-barf wrap all the way in the bottom of the booster close to the motor casing. Also dit made the Z-ties on the shock cords, both main and streamer. Did not load the chute or the streamer, will wait till the last minute if sparkies are allowed.

Update 09/10/2019 - Planning to launch this rocket this coming weekend... Weather forecast does not look good, some rain on Saturday. We'll see and wait, if not it will be Palm Bay next weekend.

Update 09/11/2019 - Checked the weather forecast - 80 % rain on Saturday, will wait till Friday to find out.

Update 09/13/2019 - Also there was a huge loop with a very very thighknot, I was able to get the knot out and gained like a foot long kevlar cord again.

Update 09/14/2019 - Launch cancelled due to stormy winds and rain in the forecast. There is indeed a storm coming in off-coast with heavy winds and some rain. Will fly this rocket at the next launch - September 28, 2019.

Update 09/21/2019 - Loaded the charges and the streamer and chute (main). Had to open up the shear pin holes in the nose cone section...Added a lot of dog barf. Ready for next weekend. Just have to load the motor when we have a go.

Update 09/24/2019 - Loaded the 2 grain Skidmark motor into the 3 grain casing with spacer.. Added 2 extra O-rings to front and back of motor and used grease to slide in casing. All set and taped off. For this flight I'm using a 65" Micheal West parachute with little spill hole.

Also Stratologgers tested out and ready for Launch.

Update 09/26/2019 - Off rail speed is a bit low 42 ft/sec, so I have a back up motor to go if weather conditions are to windy Blue streak J293 BS @ 46 ft/sec take off speed from rail.

Update 09/28/2019 - LAUNCH DAY - Started with dark cloud cover and drizzle all morning, off and on, but we decided to launch anyway, drizzle was very light and had some dry moments in between, actually stopped around 11 am... No issues with installing the sled and Iphone.. Used RTX and Dog tracker and had signal instantly. I used the J250 SK anyway despite the ow take off speed - 42 ft/sec... Rocket launched great off the pad, hardly any winds, streamer came out nicely and main deployed without any tangle, I guess I found that sweet spot to connect the streamer to the shock cord. Rocket landed in field nearby.

Have great video and date from the Iphone ! streamer performed great !

Hi Tim, Well on my first flights I had he streamer attached all the way at the end of the chock cord, actually where the chute is and close(r) to the AvBay. And yes It got tangled that way. Now I attache the streamer to the other end of the chock cord, where is leaves the booster, just a foot out there I made a loop to attach the quick-link/swivel of the streamer and since then I have good results.... When the main comes out they might get close at times.... I just love the visibility when it descents....

Freddy - what is the sweet spot for a streamer? How do you position it? I have one but not as long and it was a tangled mess the only time I used it!
