    Sold Featherweight Tracker System

    How new is the ground station? (IE - does it have a serial output over the USB port or is it just for power delivery)

    NSL East Announced

    I'm surprised there hasn't been talk of hosting any of the major launches at URRG for a really long time. It's a great field to fly at, especially in the late summer.

    NSL East Announced

    East... Western Indiana, basically due south of Chicago... Yeah, I'll be sticking with Red Glare and URRF. If the waiver was higher than URRG already has, I'd think about it, but I can't justify driving 10+ hours basically due west for the same waiver altitudes we've already got on the actual...

    Yeah, I agree it's a bit of a niche problem, but my comment is just that I feel like it's a niche problem that doesn't need to exist. There are plenty of unused numbers around any of the designations, and I don't really get why there wouldn't be at least some effort put into avoiding collisions...

    yeah but you aren't going to confuse the H123 with the G123 - if I say I'm flying something on an Aerotech G75, you don't know if it's the sparky or the blackjack. Or, equivalently, if a TARC team sends a PO to their school's finance person for a dozen F67-6's, there's two very different motors...

    Yeah it's much less of a problem when it's a designation across multiple manufacturers - I'm mostly concerned with designations being doubled up within the same manufacturer. Heck, if you want to keep the F67C as the F67 for historical reasons, make the F67W an F68, which is currently unused...

    I may or may not have acquired a G75M from my school in similar circumstances...

    AeroTech Open Thread

    I've been a bit worried about the F67C, since it's named the same as the F67W - I've always found the dual-naming of motors to be easy grounds for confusion in communication, and with both of those F67's being potentially good TARC motors, I can easily see some school finance person unfamiliar...

    Can confirm that the K1103 is an awesome motor. Flew my first one at HNS last summer, and instantly fell in love. Prop X and NBT are easily my favorite propellants at this point, though I wish there were more options for both - 38/720 reloads???

    Yup! I'm gonna pretend that file totally wasn't on the last page or anything. Definitely not.

    Do you happen to have the length from the bottom of the aft closure to the top of the forward closure? Gotta make sure it'll fit in my Punisher 5 as I'm building it

    Sold Two LOC Precision Kits

    You might want to specify if it's a current-production EZI-65 with the included motor retention. I think they also finally upgraded it to 1010 rail buttons instead of the launch lugs.

    Sold Trailing Edge Technologies 'Estate' sale (DFW Area)

    Damn, I really wish I was in the financial situation to offer to take the whole lot for what it's worth. FYI, those prices on your spreadsheet (especially for the cases) are all a good bit below their current retail value, and even lower than the best loyalty program & holiday special prices...

    Sold Trailing Edge Technologies 'Estate' sale (DFW Area)

    First off, I'm so sorry for your loss, and I hope you and yours are handling everything ok. I think there is a decent chance that what you have there is the single largest collection of Dr. Rocket hardware anywhere at this point. That is a truly impressive inventory, and I'm sure it will all...

    I assume it's premature to ask about other loads for the case?

    (This is for the flanged retainer) The section that the thrust ring is retained by is 3.270" in diameter and 0.434" deep on mine, and the opening in the screw-on cap is 2.828" in diameter.
