with that together the last step was gluing in the vent band and the extension leaving me with what should be a finished rocket! Well not quite. I still need the electronics from egg timer which are caught up in some shipping issues, vent holes and shear pins but she seems ready for paint at least
Just don't lawn dart.
hopefully it never comes to that but it is one of the names I'm thinking of for this rocket. that or greened out lol
I can't tell; did you rough up the sides of the fins first? I always rough up the area from the root to past where it comes out of the body tube. Phenolic has a smooth surface and epoxy needs some roughness to "stick" to.
yes I did i used like 150 grit and ran it along the root at the body and fin.
theres only one slight issue… it barely fits. I have wildly overestimated the space you have in a three inch body tube and wow it is biting me in the rear. I’ve managed to get the main into the payload bay basically exactly with almost no space and I have left 6 inches for the drogue and drogue shock which is very long. I guess this is what ground testing is for. I’ll see if I can get everything packed and also feel confident in deployment. I can downsize the drogue which might help some but comes with it’s own trade offs.
i may try that
I would like about 8-10' of 1/8" kevlar would work very well.
(The actual way to fix this problem would be a shorter delay or adding something like a jolly logic chute release but those take like time and planning. Wrapping the shroud lines around the parachute is just the poor man’s chute release lol)Flew it on my second l2 attemp of what might be my last flight before college starts and unfortunately a late deploy and I guess a too well packed parachute meant the seem on the phenolic failed resulting in my second l2 fail of the day
I don’t have any pictures but the plan for fixing it is som ca and then a wrap of fiberglass and we try again.
Remind me to pack my parachute slightly worse next time lmao
