There's an Estes nose cone reference guide over on Ye Olde Rocket Shoppe. It lists all the cones and what kits they were on. BMS should have them, as well as be able to upscale them for you for a dec...

Ah yes, the Bi-dent. Planning a clone or an upscale? Ken

Perhaps he was meaning it was heavy relative to the SU K250? That is probably very true. I've been eyeing the motors in that range K250,270,350 for my Competitor 3 L2 flight. Gotta build the thing f...

Now that Aerotech has the 97% K1050W in the new 2800 case, flood them with demand for a long-burn in the same case! I nudged Gary with the idea of reintroducing full long-burn 24mm motors over on TRF...

Welcome! About the only thing I'd add, would be to back up the cut to prevent tearing through the inside of the tube. Keep a stock of dowels and tubing couplers and just slide one in to support the t...

Not laughing! Interesting solution. Why not just use a high current timer (PerfectFlite)? If you've got the batteries, it will handle around 30A. Small and relatively cheap as well. Ken

Sink a threaded standoff (with epoxy) into the tailcone, adjacent to the motor tube. Then just use a screw & washer to retain. When it's not on, no ugliness to take away from a nice rocket, just...

If you go with the Performance Rocketry part, get it through Wildman or Liberty Launch Systems, rather than Curtis himself. Much quicker and more reliable. Just another thought, if you're even thinki...

It's small and cheap for HPR (justification for the wife) It won't take up much room. It won't take too long to build. Go on, buy it! You know you want to. Just wait for the altitude junkies to chime...

I have one of each but I'm afraid of having to clean that long freakin casing... 🙄 Bottle brush, followed by bottle brush with wet wipe over the end. Piece of cake! Now fly the silly things! Ken

Give me DIP switches or jumper blocks any day! Ken

Joe, is it 2 or 3 that you have? Loaning would be great, as I don't (or at least I didn't think I would) have much use for a 38mm G in normal usage. I'll get with you if I need a test fit, and defini...

After spending a couple hours of prep time for what ended up being a relatively boring flight with minor landing damage, I find myself thinking of new things... Original Excess in Moderation:-6 24mm a...

Ron's Quark has been great on the I300T. That would be my recommendation for the drag motor. Or H999? I like 'em. Ken

Ain't hi-res digital photography great for failure analysis?! Looks like you need bigger shear pins into a longer coupler??? That or a one-piece sustainer with all-out-the-top dual deployment (tether...
