When I did the vinyl wrap around mine (4″), it was a bear. Make sure the section of tube is very smooth and regular. Any little waves or even smooth bumps will throw a stretch into the vinyl and give…   Read more»

no one in this world has as much fun as bush pilots and float plane pilots, no one!ArtOh, I don’t know. My brother flew F-16s in the A.F., instructed in them, and flew in Iraq. Gotta be some serious adrenaline.Now…   Read more»

Or, take it one step further and have records for acceleration. Assuming you squeeze an accelerometer into a mosquito-esque rocket, then the LPR birds are in the running.But then there’s recovery… Ken

Whoops, wrong bird.

Clone it!But good luck finding an adequate substitute for the 1500hp Merlin!Ken

Go through Wildman or Liberty Launch Systems to get PR parts. They have much more pull with Curtis than an individual buyer.Ken

Fliskits has a full line of parts for micromax, as well as bulk motor deals.I think the 3 motor cluster mount that fits in a BT-20 is too cool!Ken….THinking of a micro-downscale of the Hot Pink Suppository of Discomfort

I’m guessing that Warren’s right. With the cost of metals skyrocketing with everything else, it wouldn’t take someone very long with a sawzall to fill their pickup.Ken

Mike,For local LPR needs, you should check out the field in Longmont, by the Sandstone Ranch ballfields complex. Let me know and I can send you a liability waiver form to keep the property owner happy. Lots of space, and…   Read more»

I’ve had some custom work done by them and they are very easy and quick to deal with. Reasonable prices and very good quality wood and tubes.Ken

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…   Read more»

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 first, tho.Ken

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, but there…   Read more»

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 tube while…   Read more»

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 one small hole…   Read more»

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 thinking of TRA altitude records, it needs to be a…   Read more»

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 in. I haven’t even…   Read more»

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
