How do you guys tend to launch your phantoms? I've read and heard that it's best not to launch off the ground because prop wash can cause dirt to get into the motors and such. For that reason, I've been launching off a cooler that I carry around with me: However, as you can imagine, it's a pretty cumbersome thing to carry around. When I go backpacking in Canada this summer I am looking for a more portable solution. I've thought about hand launching, but would prefer not to, if possible.
