    All thread size

    I’ve always used 1/4 20 all thread, but I’ve flown mostly MD or near-MD, lightweight rockets. I’m now working on an Ultimate Wildman, a 6” diameter rocket that will weigh just under 50 lbs. 16” long AV bay. Curious what thickness of all thread people are using in AV bays for larger rockets.

    Funny page-reading error.

    It’s correct when you look at the PDF itself, e.g. the degree symbol does not show as an extra zero

    L265 assembly tips

    First CTI reload for me. Any tips from those who have flown an L265 before greatly appreciated. One thing I have noticed: When I test fit the reload in the 6XL case, I can only get the tailcone retainer on 2 and 3/4 of a turn with considerable effort. It goes on 2 1/2 turns OK, then another...

    attaching eyebolt to AT single-use motor

    I'm pretty sure there was a thread about this at one point, but I can't seem to find it now. I want to attach an eyebolt to an Aerotech L1000 to be used as a recovery attachment point I have flown the rocket it will be used in a number of times with reloadable AT motors, and use a tapped...

    Where to post flight videos

    Is this the appropriate forum to post YouTube links to flight videos? The photo and video forum looks to be more about galleries of specific rocket models. Or maybe in the high power forum if it's a hpr flight?

    Using motor to place Aeropack MD retainer

    My exact question is hard to put in the title. I've seen a lot of threads on the MD retainer in general but nothing about this: The instructions that come with the Aeropack 54mm minimum diameter retainer say you should put the motor together with everything except the propellant -including the...

    adding switch band to Tomach 54mm

    I'm building a fiberglass Madcow Tomach 54mm. My intention is to get a rocket with an onboard video camera, with the camera lens pointing down, as high as possible. I was planning to have a Mobius in the AV bay and use a lens cable to place just the lens on the outside of the switch band...

    mobius lens thru switchband, pointed down

    Has anyone mounted a Mobius (or similar camera) lens thru the switchband of their AV bay, and also managed to get the lens pointed downward? I'm trying to do that on a 54mm rocket with a 1" wide switchband.

    Black Aero case momentary switch

    Can anyone who has purchased one of the Black Aero Eggfinder LCD rx cases tell me where on the board the momentary switch that comes with the case connects to? I emailed the fellow who makes them but I think he's on vacation.

    forward motor closure as recovery attachment point

    I'm building my first DD rocket, a Madcow Tomach 2.6" FG with a 54mm motor mount. The instructions state that the forward motor closure eyebolt is to be used as the recovery attachment point. In searching threads about this I have seen some postings that say using the forward closure for...

    Cesaroni motor retention

    I've been flying 38mm Aerotech disposable motors to date. They have a thrust ring, and I've been using an Aero Pack threaded retainer. I'm now building a 54mm rocket and want to use Cesaroni reloadable motors. I'm trying to figure out how to retain the motor. Not a minimum diameter rocket, so...

    External camera shroud on Mach + rcoket

    I've been using a Landru-made external camera shroud on a small rocket (Madcow Twitch) and have flown it on a J270 with no issues. I am now moving up to 54mm motor rocket with a 2.6" body tube, and will be flying K and L motors. Has anyone flown that type of a rocket with an external camera...

    Fitting GPS/RDF antenna in rocket

    I'm about to start building a 2.6" fiberglass Madcow Tomach and it will be my first rocket with electronics. In addition to dual deploy, I want to include some type of tracking. The altimeter bay in this rocket is 6" long, and all commercially available GPS and RDF devices I've looked at...

    5th Grade class project in Santa Clara County, CA

    Hi all, My son's 5th grade teacher became very interested in his rocketry and asked if he could do a class presentation on it. This led to me talking to her about a class project she did when she was about his age that involved the whole class each building and flying their own model rocket...

    rail button placement and fixation

    Thanks to everyone here for all the help so far in building my first HPR rocket. For rail button attachment, the kit directions (Madcow Twitch) say to install one button 1 1/2" from the aft end , and the other one at the CP, making sure it's behind the forward centering ring. That would put...
