I was using motor eject. My delay drilling tool only allows me to use an 8s or 10s delay. According to OpenRocket, 8.57s is optimal. I used 8s on my previous flight and the chute came out a bit early, causing some tangling of the chute: I thought this time I'd try the longer delay. According...

I'm not sure if this is the right sub-forum to share videos of launches but here's my recent LOC IV launch: . Went to 505m (1,657ft). Unfortunately the Jolly Logic Chute Release setup didn't work out. Somehow the chute came out immediately upon ejection. Maybe the ejection was energetic enough...

I also used the Mobius Mini with the Additive Aerospace shroud. Very happy with the video quality (60 fps!)

Mine has a couple of rocket launches: https://www.youtube.com/user/johtib

Mustang67 kindly asked Madcow to get back to me, which they said they would the next day. However I've still to hear anything from them after over a month of trying to reach them. This is especially frustrating since I need replacement pieces to continue my build since a) their instructions for...

I noticed that the switch band (which goes on the outside of the ebay) isn't cut 100% straight. When I put it against the body tube and rotate it I can see that there's a gap between the two pieces in some sections. How can I fix a cut in a fiberglass tube to be at 90°? Ideas I've had: Wrap a...

Same here. I've been trying to get in contact with Madcow for about a month, both via email and their website messaging system for logged in users.

The (pilot) holes for the rods came predrilled from Madcow.

I'm building a 2.6" Madcow DX3 and space is at a premium. It's also my first dual deployment setup with an ebay. I've included two pictures of how I plan to add the ejection charge canisters and terminal blocks, while leaving space for rods, nuts, washers, eyebolt, and two holes for wires. Does...

I checked Apogee, Sierrafox, and a handful of other website that Google turned up. Everyone is out-of-stock of these closures. I find that quite surprising as I guess they would see quite some use. Anyone know of an online retailer that has these closures in stock?

I'm building a Madcow DX3 2.6" with dual deploy. Space is really at a premium when trying to fit two ejection charge canisters, the eyebolt, the nuts for the sled rods, and two power connections on top of a 2.6" bulk head. I need some thin ejection charge canisters (length shouldn't be a...

There's a local dealer in Switzerland (Spacetec) but I don't know if he can ship motors. Sent from my Pixel using Rocketry Forum mobile app

Just to bring this thread to a close. Deb reached out to me and my L1 card arrived in the mail yesterday. :) Sent from my Pixel using Rocketry Forum mobile app

Thanks! If there's time it'd be great if Tripoli looked into that contact form or just put an email address on the website so we can avoid the form (and any related problems).

I'm sure there are good reasons. Thanks for helping out. I'll sort this out with Deb over email.

Could you share the email address? I only found the website contact form. Sent from my Pixel using Rocketry Forum mobile app

I sent my L1 paperwork to Tripoli about 6 weeks ago and I still haven't seen my status update on their website nor have I received a new membership card via mail. I've also tried to contact them via their website contact form twice without any reply. Is this normal?

Thanks for all the replies. I've skimmed all the linked threads. Very informational. A perhaps silly question: for switches (e.g. screw switches, push switches) that require that you reach into the airframe through a hole in the switchband, how do you make sure the whole is aligned with the switch?

I'm building my rocket with an ebay and was looking through options for turning the electronics on and off. All options seem a bit annoying to build or use. Options I've seen are: Cables twisted on the outside of the rockets. I guess this works but I'd like something more solid. Switch on the...

Does anyone have RockSim/OpenRocket files for this rocket? Neither Madcow or RocketReviews.com have any.
