M.daSilvaI ran into a small problem: the Arduino module is too big, and I can't fit the SD card reader inside!
So back to the drawing board!
I chose a smaller Arduino Mini board stacked on top of the SD reader. I had to chop some plastic off the support I printed to allow the slot to be exposed. The programming header is also broken out, to allow future debugging/reprogramming, without having to take the whole thing out of the rocket.

Hi, question about the radio transmitter. How are you using this to locate the rocket?
Are you sure? yes | no
Hi!
I'm using the transmitter as a simple beacon: it transmits a continuous pulse, and with the help of a directional (yagi) antenna, I can direct myself towards the rocket. Here's an example of a use of that kind of tech:

I plan to add in the future a GPS receiver and use it to send RTTY data through the 433MHz TX, to get a direct readout of the position...

Build a bigger rocket :)

I'd like to keep it as light as possible, yet I want to stick the most powerful engine I can find (and afford!) in it! But I'm legally limited to 300m for now... :(

I follow the wanting to keep it small. I ended up finding a local club allowing higher launches via FAA permits, and to afford the bigger motors I built my own... Though probably didn't save money in the long run, almost 20 static tests and I have an effective motor design capable of hefting my rather large 6lb rocket skyward. I'm a fan of creating everything in a project, so everything including motor, rocket, nose cone, parachutes, and electronics are all custom in my project... Best of luck
