I have some problems with my Telemega V1.0 firmware 1.64, Regardless of the orientation Up, down or horizontal my Telemega boots always in the idle mode. Also if I reboot it over the radio. The next problem is, I can not communicate with it over usb, neither on Windows or on Linux. I have tried...

Together with the last tubes for my L3 project I ordered also a 38mm Min Tomach from Madcow Rocketry. Come already prepared for DD and you can get matching parachutes, nomex sheets an kevalar tethers. The bodytubes are thin fall fiberglass, while the couplers have regular thickness. I also...

I have the plan to be the first one to certify TRA L3 in Germany . We have several L3 flyers but afaik they all did their certification flights in Switzerland. Now that we have a TAP in Germany, it will be possible to certify here although we have some strickt bounding conditions. The most...

Did you ever had a casing which was too small? I have here a rouse-tech 38/720 casing which is to small for AT liners. The liner is ok it fits in all other 38er casings I have. I've tried to sand down the liner but the casing is really a lot too small. Finally I broke the phenolic liner. I...

So today is the 20. of may and I have still heard nothing from the old RW management. Paypal decided the case today in my favor, since there was no answer from RW to the claim and they were able to recover the funds from RW. Very sad that this had to end this way, since I have ordered almost...

I wanted an altimeter which is so cheap, that you can give it away to kids during launches. Model rocketry is quite uncommon in Germany, and where are happy about every kid that shows up at a launch. While we regularly give away model rocket motors, altimeters are normally too expensive. So...

You think the motor casing is the minimum diameter, every tried flying without it? This is a CTI K445, it even has the packaging as tube fins and flies on a D9-3.

Some of you might know the Estes CATO. It is a kit from estes which is designed to disintegrate during flight and come apart into 7 pieces, triggered by the ejection from a booster motor. I wanted one for some time but it is quite impossible to find one in Europe, so I designed one on my...

Hi, does anybody know an Altimeter with a variometer which is based on acceleration data, which can be used as a high speed falling detector after apogee? I would like to have something like this: If Apogee was deceted by acceleration based speed and after that speed gets lager than x or...

I launched a 2 stage rocket today D12-0 to E9-6 beautiful flight, staged perfectly. But when I recovered it I found that the entire engine mount tube in the booster had been completly incinerated. The gap was about 8 inches. Anybody know what may have caused this?

I made a 2 stage rocket, 24mm upper, 24mm booster with 2 parallel 18mm on the sides of the rocket. I want to make sure the burn time on the 18mm engines doesn't exceed the burn time of the 24mm booster engine. But my question is, does the upper stage light exactly at the burn time on the motor...

I launched my first D to E Powered 2 Stage rocket today and may have broken the 2000 ft. mark. ( I'm still running the calculations on the sim) sORRY ABUT THE BLURRS, I forgot to change the shutter. Beautiful Day, HAPPY EASTER

Im doing some studies on Max Lift off weight, In one method (with Rocksim) you need to input minimum velocity for stable flight and compare it to the speed at launch guide departure. So how do you determine the minimum vel. for stable flight.

SORRY ABOUT THE SPAM Does any one know how to find the ejection force values on standard BP estes engines. or if 24mm motors give a more forceful ejection than 18mm and so on. Im creating a recovery device that may require a very low blast or a way of de-pressurizing the sustainer. thanks.

Is there any way of finding out the force of the ejection in each engine.mabey in lbs. PSI or something ?:banghead:

Are all ejecton charges the same or is, say a d-12 stronger than a c-6. and so on

Does anyone know why there is such a big difference in the CP between these 2 methods ? and which one do you prefer and is one more reliable than the other ?:rolleyes:

I've been kicking this idea around for a while. Ever since I built the Estes Sizzler (with rear ejection) I thought I'd try something where the nosecone stays attached.I finally came up with something that I think will work. I built this Proto type. The one thing I'm worried about is, if she...

I tried making one but its only good for 1 size tube.Does anybody have design for one or know where I can buy one ? :)

I have a bunch of NC 56's.What am I going to do with them. Nobody seems to use these except Mfg.in the kits. does any one know where to get the tubes for these things.
