    Which styles would be good for rx, and which for tx, if I were to pick one to build for low range stunt flying?
    Get me a Crocodile sandwich. And make it snappy.

    I have some advice to give after building 910mhz windmill and fan from this method

    -leave the center conductor 1/4" too long while assembling, then trim it before soldering to coax. It's easy to cut shorter but to replace it with a longer one, the top of the antenna has to be taken apart...

    -when soldering the elements to the coax shield, cut a small hole in a piece of paper and tape the elements down with the contacts all together and protruding through the hole. Just like when the elements were placed for soldering to the center conductor. This will keep them all together and spaced nicely for an easy join... the alternative is to have six hands to hold everything, plus one for the soldering iron and one for the solder.

    -it's quite difficult to make the last bend, due to the angle. I made a jig, but it's a kludge. My advice is to make a good jig.

    With my handmade 910mhz windmill/fan (that do not look like the pictures, I am bad at this) I flew 1.6km distance today before my (2.4ghz) radio flipped the script. The video was great. Now to find some elevation. This was near LÚvis, it is very flat.

    Ah yes, one more thing. I was at the opposite end of a field and the video cut suddenly. I lifted the goggles to check the antenna (maybe it blew over?) and a spider was making her nest on the antenna, and shorting it. Lesson learned: hot glue the base of the antenna, it will prevent shorting due to spiders.

    1280, maybe 1240 too unless the 1280 will work on 1240
