Loc Goblin Thread

On board video from above 4" LOC Goblin maiden flight. Camera is original Mobius in an Additive Aerospace shroud at zero degrees.

Awesome! I was saying out loud "drift past the tree line" and as it did it was all good.

Flew the LOC 4" Goblin on an H238T with 6 second delay today and got L1 cert.
Forgot to take photos or flight video but have video from on board.

Was pretty windy so it drifted a ways from the 956 feet apogee. Luckily I put an Eggfinder GPS on the shock cord and has able to walk right to it. I did need to get within 15 feet to see it in the high grass.

Jolly Logic Chute release would have minimized wind drift. Nice flight.

Congratulations on the Level 1 certification. I use JLCR set to 400'. Never difts off that way...

400 ft ! That makes for some tense landings till the ‘chute opens up.

I did plan on the drift and we setup at a location in the field to drift over the open fields and not over the thick tree lines and cow pasture. A chute release at 400' would have drifted a bit more than half what it did.
Also with GPS Eggfinder on board I knew I could track it and find it.
With the winds I consider this a near perfect flight. If the wind was a different direction I would not have flown and waited until our next launch for the cert flight.

I do fly DD rockets at that field with the main set to 200'.

I know a lot of people use and like the JLCR but I have seen quite a few failure include L1 cert attempts. Since I've never used one I was not going to do so first time on a cert flight.

Now planning on L2... I am thinking on making an AVBay and extended BT on the Goblin. Then run full redunent Dual Deploy with a J450. This can not be done at our club's field so maybe next year at Red Glare. In the mean time I do want to get down to MDRA and fly some of my larger DD rockets on H and I motors.

I do admit that I blatantly stole the idea from jd2cylman's "mistake", but I kinda took it up a notch. She will have her first flight July 4th weekend. "Midnight Goblin" a LOC 4" kit with carbon fibered body tubes and CF tip to tip.

Midnight Goblin looks great.
With CF'ed BT and fins what motors are you planning on, K2050?

 

[RocketmanAleks]

I was gonna say "Put a K2050 in it!" but it looks like I wasn't quick enough to be the first.

So I FG’d my body tube, attached the fins and then FG’d tip to tip and (4oz with West Systems) and I’m going to have a TON of sanding to do. Can you give the Readers Digest version of what you did ?

Adding my 4” Goblin to the mix. First flight was yesterday at the NOTRA launch in North East Ohio. Still honing my iMovie skills.

My daughter was key in the construction. Even though only 10, she loves to assemble kits and help assemble the motors.

Stand byyyyyyyyyyyyyyyyyyyy...............more info on the "What did you do rocket wise today" thread and my intro.....gona be moving it over here now, weather is still "ugh" but finding work arounds and it's coming along.

Goblin.

Nuff. Sed.

Make a loop of lock-wire to go around both Z-clip screws on ACR, insert fin can til FCR hits 30 min. epoxy pull back a smidge to squeege the goo on the aft side a tick then sneak a finger in the BT to pop the Apogee aft rail button T-nut through with a smidge of 30 min. on it then shove the can home, grab a dowel and build up fillet on FCR from above, spin by hand for 30 mins w/ heat on it, let it cure for a couple days in the curing tent (cold here) with a small fan forced space heater, (I converted my dinette into this tent here at the little camper in the boonies, meals on the sofa for a while...but hey, it's a Goblin, it's worth it). Then...

Next up- Aeropack 54-38 retainers. Not using the 38/29 stuff that came with the kit, which actually works perfectly and is a VERY nice inclusion to the kit IMO. Props to LOC for that.
