I have an unbuilt, new in box Aerotech cheetah kit. 40$ plus 14$ shipped in CONUS.

So I was flying an ATH45W in my 2 stager this weekend, and the motor didn't light (probably due to electrical error on my side), but I was trying to get some best practice ideas. Normally I use CTI motors in the upper stage due to the starter pellet. Wildman Tim suggested using an ematch for...

I did some sort of java update on my computer, and now OR won't work. I've tried several versions of java, and also the standalone OR program (with the built in JRE). Nothing seems to work- what should I check next? Thanks!

38/1200 case- This is the big 38 K motor case! Used only once. This is only the case- no snap rings, forward closure or nozzle included. 70$ + shipping. 29/240 case- this is a rarity! Full case with closure, nozzle, etc. looks like it’s never been used. Loki isn’t making 29mm reloads...

Anyone going? Forecast looks good so far. What flying? I have a few EX motors in the works

So- I'm looking to build a rocket to do one thing: 1. Break Mach 2 2. On a MD CF scratch built rocket 3. With an EX motor Ideally it would be a reusable airframe, but recovery would be enough. The main design is 54mm with carbon fiber body tube and fins (from SinfulDarkLord on this forum). AV...

Anyone going? I'll be there, flying some stuff.

Who will be there? I've got a few things to fly, although not sure of the full list yet. Preliminary forecast is showing decent weather, except for being cold. Any idea of the condition of the roads/runway there?

Who will be there? I'm hoping for less snow, and clear skies! What are you flyhing?

Who will be there? First launch of the year at Bong! Not sure what I'll be flying yet... probably just some smaller stuff.

I have a small cluster rocket (4x24 motor mounts) where I'd like to set up two of the motor mounts as an airstarted cluster. Size/weight is a concern, and a friend of mine offered me his perfectflite minitimer. However, I'm a little nervous about it's accelerometer failsafe. Thoughts on the...

After a not so good experience with CTI Blue streak, was just thinking which propellants people are using for upper stages? I'm thinking of ease of ignition, etc. FWIW- i'm looking at doing a long burn sustainer motor at MWP this weekend. Trying to decide between the AT H45W or the CTI I55...

Last Bong launch of the year! Who will be there? I should be trying the 2 stager again if the weather cooperates and I get it prepped in time (I'm out of town until Friday 9pm). I might also fly my wife's Fliskits paylord on 3xB6-4 motors in honor of the end of Fliskits. Maybe other stuff-...

Who will be there? I'm only able to make it on Sunday. Going to make another attempt with the 2 stager, plus fly my 4" Punisher on a K780.

What are people’s thoughts about these? I’m hearing about a lot of issues lately, although it could be a telephone game :)

Anyone going to be there? I'll be flying Wildman 4" Punisher- on a K something something.. depending on what Tim has in stock. 29mm MD rocket on G126WT. Assuming I can figure out a way to fit the tracker into it. Maybe the 2 stager, if I get off my lazy rear and finish it. I470WT staging to...

Looks like a great forecast! What is everyone flying? I'll have- madcow godevil 29md on G126WT Wildman Vindicator jr- alumaflame G120 EX motor Wildman 4" punisher- Alumaflame K960 (assuming I get everything built in time).

So- for those of you who have the new style tracker (circle/coin shaped, compared to the old box), have you had any problems keeping the antenna attached? I've had to replace antennas 4-5 times on the new ones, which causes all sorts of issues when they pull loose on a flight. What are you...

Kit was only opened to look at the inside.. Great starter if you want to get into 29mm mid power rockets! $30, plus 5$ shipping. I can deliver to QCRS or Bong as needed.
