    Ho,
    Yes you are right , 2W is difficult to find in nice package. Did you test the power out put to dummy load?
    Nice airframe , please tell us more about it. Thanks

    Hi Ho,
    The price of each AC4790 is 77.5 US$ , so how is it higher? Are you talking about SDK development kit? SDK kit from digikey is 199$ US now , it was 225$ when I bought it last year :((

    I have used CL4790 & AC4790, too. The price higher then this one.

    The real price should be request to it's company. In current product, it is hard to find the small Trx with 2W emission power. I had tested the Trx in 30km with 57600bps(5.76k byte/s) via this vehicle.

    ok Ho, thanks , But 150$ price will defeat it, currently two other very good products are in range of 69 - 89$ each. The programming interface are also easier than your model. We need consistent data speeds >=19K.
    Yes looks like Pen style WiFi booster , so should be 30-50 gm I guess.

    One Trx is below US$100 in Taiwan that I bought. I think maybe below US$150 for the foreign customer.
    You can mail to the company to require the quotation of prices.
    I don;t sure the weight, it's very light can be put on the "EASY STAR".
