I had one, liked it, still sold it. Receiver is very large, if you try to use a spektrum one you'll need to rebind a lot. But there are no product updates anymore. They focus on the military product, wich is noble but not for our needs...Service is still up, can't say anything negative about that. But after 2 years of racing I changed to a Kopropo Helios, I like to change radio's before they give any kind of trouble or glitches.
