    An Introduction - The-Rocket-Store.com

    I would recommend registering with google and other search pages. I tried finding the web page typing the website into the google search, and nothing of the sort comes up. Had to type the physical address in the top. This isn’t an issue for those who have found this post, but will be for...

    if you do get a quote, see if they do bulk discounts? Maybe we can get a small group buy going for those who are interested.

    What Do You Think About 3D Printing

    With how small the rocketry hobby is, it’s pretty safe to say that the only real room left for innovation is with 3d printing and electronic software/hardware. It’s also safe to say that if we alienate what the new rocketeer’s enjoy, just because it isn’t the way you are familiar with, is a fast...

    What do you MPR and HPR people think of Thrust vector control

    I don’t have an engineering analysis examples, I’m just a diy builder/racer. But betaflight is the top open source firmware in the industry, and Joshua bardwell has a ton of videos explaining features and how too’s on betaflight. You could search YouTube for Joshua bardwell tpa or something...

    I would assume t4 is good stuff.

    I personally have only used the tip of the syringe, but I don’t see why a blade wouldn’t be good, just be careful not to cut through the epoxy coating on the board. If you have many small traces in a row, you can just take the blade and wipe it right down the pads, and because the paste’s flux...

    What do you MPR and HPR people think of Thrust vector control

    I read apost from AT on Facebook talking about the challenges of these long burn motors. he was discussing something about the burn temps being outside of certification requirements. And I believe he was saying that he was going to propose the change with the gov body who sets the standards, as...

    What do you MPR and HPR people think of Thrust vector control

    Tpa is throttle position attenuation. It reduces the pid profile(gains) based on throttle position. Most fpv race drone flight controllers set the tpa break point at about 75% throttle and reduce up to 15% on a default tune. It’s a very good way to get rid of high speed oscillations.

    you really just need a small smudge of paste. If you think about what they’re doing when using a screen to apply the paste, it’s basically just wiping the paste a little thicker then the thickness of paper over the pad. Make sure the paste has warmed to room temp for 3-4 hours before working...

    What do you MPR and HPR people think of Thrust vector control

    the reason the rocket wobbles as speed picks up is because the eagle tree guardian is a very primitive flight controller...gains are set at a single point for the entire flight, and she obviously had to find a middle ground where it would still correct at low speed, but not wiggle terribly on...

    Sold MARSA 4 50g Flight Computer-Price Reduction

    Just a heads up to help you sell it faster...the brand new price is 190$

    because the circuit board hasa coating between the pads, you can literally draw athin line right down the pads for a micro processor. And when heating with the air gun, the solder will naturally move from the space between the actual copper pads, and collect only on the pads. The mask method...

    For those interested in why 60/40 solder should be obsolete in the marketplace. Here’s a copy and pasted explanation 60/40 solder is made of 60% tin and 40% lead. It has a melting point of around 190°C, depending on the exact composition. Iron tip temperatures of at least 300°C are...

    you can find bulk repackaged versions of kester ep256 solder paste for 15-25$ On eBay and its what I would pick up. But anything from one of the main players is good...kester/sra/mg chem etc...look for solder paste that uses no clean flux, and I would recommend a paste that uses 63/37 tin/lead...

    that’s the one I purchased...granted Iv only used it a few times, but it works as it should...I’m sure none of these cheap options are production worthy, but for someone putting together a few eggfinders per year, I’m sure they’ll last you a decade+...I bought a similarly cheap soldering station...

    If anyone wants a nice budget system, here’s one with the hot air gun and temp controlled iron solder iron. https://www.ebay.com/itm/750W-Soldering-Rework-Station-SMD-Iron-Desoldering-Hot-Air-Gun-Tool-3-Nozzles/174271166320?hash=item28935ef770:g:gcoAAOSw1bFer99t And if you prefer digital...

    Yea it’s pretty amazing, I can’t believe it took me this long to buy a hot air rework station, a lot of drone flight controllers went in the bin that could have had a voltage reg replaced in a few minutes. I’d even venture to say that anyone who got a cheap reflow station and a 5$ practice board...

    Also, sra and kester are my two fav solder brands...although my iron melts sra 63/37 solder faster then the kester of the same diameter that I have, so I prefer it over the kester.

    You can pick up an 858d hot air rework station for 35-45$ on eBay or amazon...I just got through a practice board using the one I just purchased, and I can’t believe I haven’t owned one of these yet...makes soldering surface mount components mindless...tip: use way less solder paste then you...

    Multiple Choice Dual Deployment

    I don’t think there would be much issue doing this with the proper altimiter...you’ll obviously need something with 3+ channels, like a raven4, eggtimer proton, Marsa 33L etc...the biggest problem will be having 2 main chutes in 2 payload sections, and having a drogue chute...the most simple way...
