8) Just a thought....K270/2560 case, $140.00 😀

If that's an offer I'll take one. I need that case anyway. Are you serious or am I missing something?

8) I have both the Load and case. The 'Just a thought' was for the min.dia. bird part. It just seems to me that if a person wanted to try for personal best, say 20,00 ft. This might be a great way to start down that road. For me, I am using a Firstorm 54 and the K270 with one of the trackers that are around. For not too much money, should get 3+ miles. Maybe 20K by Oktoberfest? The point being, with so many motor to choose from, the sharing of trackers, light strong airframes that are out there, it is a good time to go "high'. 8)

😳 The K270 which fits the 54/2560 case is 140.00. The case is extra 😳

I've got the case I can loan if interested. Heck of a good deal in my eyes. And a transmitter to boot, if you're in for the walk.

I'm almost afraid to ask, but how much does a K250 cost? I've still got quite a few rockets to build and fly before then, but someday I might like to go for the K record.

Adrian, the current K250 is a shadow of it's former self. The vintage K250s were a 100% K, the new ones are ~81%. Last I saw they were ~$275 + s/h + hazmat. In other words, an M from Tim is cheaper 😯

The Loki K350 is very (very!) long, and the hardware is quite heavy... large graphite nozzle, big honkin' forward closure. I'm going to fly one later this year, but I don't think it is the answer.

The market needs a full, long-burning K... Cesaroni worked on one for a long time, but it never made it to production.

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 was little response. Maybe more nudging by actual record holders? 😉

Regarding the long burn K. I have, at various times, begged / groveled / pleaded / whined / and even asked nice 😀 I've spoken directly with the manufacturers. Everyone says it is a "nice market", they'd be a "premium load" (translated: EXPENSIVE). There seems to be interest, but nothing ever emerges.

For my part, I'd love a full, long-burn J, K, and/or an L. The aforementioned Loki K350 comes closest, but it has some challenges as noted above.

Actually you would be surprised how light the hardware is on the K350. It is only a 54mm load and hardware. Ive flown 98 % of my flights with snapring hardware and in comparison it isn't as heavy as one thinks. Even though it has a heavier graphite nozzle vs say the AT phenolic... it has an advantage there that I believe offsets the weight disadvantage. The thrust and power is carried for a longer better duration due to no to little erosion factors like the phenolic nozzles from AT have that erode at a very high rate. The closure on an AT vs a loki/AMW/snapring hardware isnt much heavier. Have weighed several in comparison and they are pretty close. Even more so if they have a well in them for a delay or smoke. Just my experience and opinion anyhow but take it for whats its worth..

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.

Indeed, the K350 is heavier relative to the Aerotech K250. The Loki load is also a good deal longer, coming in at nearly 29". Rockets that I built for the L330 are too short for the Loki K350, and due to design issues, I have some real challenges there. All I can do is hang the motor out the aft end - which is exactly what I plan to do. It seems like a cheesy way to go, though 😳

The good news on the K350 is that you have a much better anchor point up top, and you get rid of the medusa nozzle. I am not a fan of medusas (that would be kindling for another thread). The K350 is a fine load, and I look forward to flying it. I just don't think it is "the" load for a K altitude attempt.. and sadly, I don't see anything else that even comes close. The new K250 is 2x the cost and ~450NS less total impulse.

Hey! BDCR flew a number of times that way. It was designed for the AT M1315 but someone got it in there mind that I should fly the M2200 and M2500 from AMW. Since motor retention was from the forward end, I just added a 9 inch piece of tubing. I guess it did look kind of strange but it flew fine.

Doug, that is good to know - It looks OK in Rocksim, I'll check the CG/CP on game day.

Wayne Mrazek - Hybrid Pioneer and all around AWESOME guy flew "Quadrophenia" - a 4xM cluster - with all of them hanging out.

I am assuming most have heard of Wayne's untimely passing a few weeks ago? Wayne was a great man in and out of rocketry and he will be missed. Sometime around the campfire I'll tell a cool story about him. Awesome guy.

Always good to check the CP/CG with a mod like that. Mine was not minimum diameter and had over sized fins. I would like to hear the story about Wayne. John, are you going to be in CO for NCR's launch next month? I am going to make every effort to be there.
