Not every flight goes to plan, and today that's how it went. 7.5 out of 9 were successful. The half a point was for a cluster rocket that didn't fully light off the rail (3 out of 4), but was still recovered.
Three pics. The smashed one is the newest version of a BT60 Goblin. Again the chute release pin didn't let go despite several successful tests with the small chute bundle. It made it to 2878' on an Aerotech F67C motor.
The black sleek one is an upscale Estes Ninja, 2.5" diameter. Flew on an Aerotech F40W. Perfect flight to 1500'.
The skyracha rocket, a 4" upscale Big Daddy, flew great on a H130W to 1354'
Here's the second version of the BT60 29mm motored Goblin, ready to fly this weekend. Shakedown will be on a F67W. Loaded with tracker, chute release and Eggtimer Apogee. Fingers crossed all goes well, then we shoot for 4k feet with a G80 at LDRS.
Paint is Krylon gloss rich plum with Testors Purple Fog color shift over it.

Kid and I raced #WORS #MTB today. Much fun was had. He did well. Me, fitness is lacking....but it was a great time! #BikeTooter
All these statements check out.
BT60 Goblin didn't completely survive a failed chute release from 1342' (not enough tension on the band to pop the release pin free). Pointed out a flaw in my fin print/design. Printing new fins and can now. I tried to epoxy it; just not going to be good enough.
@Ve3ldj Ha!
Hope you figure it out. If I were encountering the same situation, I'd just give up and throw new pads and a rotor on it...or at least new pads and hose the rotor with brake cleaner 😃
Wasn't planning on swapping out a broken sewage/waste pump this afternoon, but sometimes that happens.
I had went downstairs to get my fish filleting board and heard something running that shouldn't have been. Motor on the pump was spinning constantly. Figuring it was just a bad float switch, got the pipes undone and cover off the crock to discover it was full of water. Oh, goody, not the float.
The impeller on the pump decided it wanted to be in several pieces; making it hard to actually move any water.
Luckily, the previous owner of our place left an old pump here and years ago I tested it and it worked fine. So, it's in there now and all is well; but going to get a new one ASAP.
@Ve3ldj Hydraulic? Lever spongy or have a really solid stop? If spongy, then a bleed would probably help.
LDRS G80 altitude contest rocket is ready. I won't win, but am going to go for personal records. BT60 upscale Goblin, printed fin can and nosecone (my own designs). Fits an Eggtimer Apogee, Jolly Logic Chute Release and Marco Polo tracker. #rocketry #modelrockets

Cat for scale.
@bryanhansel November's not too far away. Why go through the effort? :)
@Miq I'll print another set to keep as spares should they give up on a ride. We'll see how they do. Always fun to try stuff out and see what happens.
@Miq This first attempt is just PLA.
