Will do. Thanks for the input. I guess I should listen to the guy with an Iris for an avatar.Personally, I'm not a huge fan of having the main and drogue flapping around together on descent, so not sure how well that works out. Could be fine, but also the possibility of entanglement.
Otherwise, I think you could cut back on the tape a little, it is a fairly light rocket. I've used size 8 rubber bands (the little ones) to hold the cord together but release easily.
I used more tape than I would for flight just to keep it together while i messed with it. The streamer is 4”x15’ bright orange polyester.Was going to chime in on the tape... I typically have used painters tape instead of masking tape. At least my understanding is tape keeps chords orderly for deployment, and supposedly help reduce "snap".
How long if streamer are you using and what width?
Maiden flight is April 17th. The on-site vendor has an I280 literally with my name on it. The problem right now is dry season. The drought index has to cross a certain threshold before we can use sparky motors. Hoping for rain between now and then.Looking good! I flew a i280 last weekend in my goblin, sweet motor and good choice!

Question about that motor: I didn't select it just because it's cool, but because I want this rocket to get moving quickly off the pad to overcome it's slight over-stability and the I280 thrust profile looks ideal for this. But I've watched several vids of this motor in use and it seems in almost every one the rockets "whip" off the pad or weathercock severely. Is there a correlation between the two? I can't see how the motor would cause that, yet it was a common theme in the vids.
That motor stays above 300 n/sec almost it's entire burn. That should get my 5 pound rocket out of town pretty fast, shouldn't it? How did your Goblin fly?
Fun Fact: The I280 spikes to 78 lbs. thrust at ignition and levels off at 68 lbs. until a rapid taper-off.
Loc always sends a smaller parachute. I always have to buy a bigger one. Im starting to wonder if they do that purposely.Watch landing descent rate. With those big fins right at the back they are vulnerable. My Loc IRIS 2.25" maiden flight came down on the farm road for our launch site. Cracked a fin. Now fixed, but I increased parachute size from the LOC supplied one quite a bit.
