I thought you were going to use an H268. Doesn’t it sim a little faster? The impulse is almost twice as high if you can fit it.If my little rocket passes an Estes motor checkout this week, and I get…   Read more»

8) I do stock the H238, and I have both sold and flown (last weekend was the last one) without any problems. I sent up my Bull Pup up in Utah with one. As you know, I plan on using…   Read more»

Tim, do you stock the H238 in a 29-180? And has anyone had trouble with it?I’d like to get some data at 100 G’s+ with my new 250G-capable Parrot, and I think my new rocket will be able to take…   Read more»

That K motor was EX and it had a very tiny “web”, meaning the core was just enormous. I think it was barely a K. Just seeing the case was wild. The rocket that it flew in was called “Shockwave”…

It seems that dividing records by impulse range is the only truly logical solution. John and I have had a fair amount of discussion about altitude records over the last few years and one piece of fallout from that has…   Read more»

didnt know they made Redlines for that case! isn’t it like 70 dollars a reload for that case? kinda crazy! all the clubs J motor alt records are on that case…. why isn’t there the 720 case records for J…   Read more»

My apologies if I overreacted – I’m just a sensitive guy 8)Stepping a wee bit off the track of this thread, has anyone ever flown the redline that goes in the 38/1080 case? That is the same case that the…   Read more»

And by the way, I also interpreted the “you” in “Do you really think that I dont know how…” as directed at Aerotech, rather than John. Aerotech….. not our boy Johnny!I have only seen it in the small 29mm motors…   Read more»

8) I think Doc was refering to Aero saying that it was user error. I just am not buying that at all. I have found that I see it in the H165/ 29-180 case most. Hey, anyone can have a…   Read more»

8) A quick look at my BATF paperwork shows I have sold 72 H165’s in 3 years. Most all flew fine. The ones that were a problem were around the same time period. Maybe a bad batch, we will never…   Read more»

I’ve flown many H165R’s without any issues. Gotta make sure the o-rings are in the right spot tho…

OK, I’ll report to sensitivity training in a bit 😐 the idea of cooling in minimum diameter rockets is pretty interesting… that is all I have flown redlines in.I’m curious if the K270 has had any issues? Very cool looking…   Read more»

I wonder what factors make the failures more or less likely to happen, and if there is anything we can do to reduce the chance of it happening.Some general questions:Does the liner burn through before the case fails, rather than…   Read more»

Heh – the “stupid nonsense” sentence made me laugh. I read that as an extension on Tim’s “my ass” comment – as in, the manufacturers are saying that the rupture is assembly error and that is just stupid non-sense.

Yikes, something is up there. I’ve never heard of a motor doing that? When you say “blows out the side of the motor” are you saying the motor case actually ruptured? or that gas escaped between the closure and the…   Read more»

8) I have seen 6 or 8 H165 smoke the case in the last 18 months. I do not fly that motor anymore. Aero poop pooped me when I asked about the H165, they said it was user error. (my…   Read more»

I have blown 3 29mm casings out all on redlines…. its kinda annoying when you make the motor correctly and then it blows out the side of the motor right near the aft closure 3 times and with 3 different…   Read more»

I think I have the H268R reload, and no casing….I have blown 3 29mm casings out all on redlines…. its kinda annoying when you make the motor correctly and then it blows out the side of the motor right near…   Read more»
