I have just had an Evo Kit Plus fitted my Phantom 3 professional, I have yet to test distance - but hope to later next month. It was fitted by Fredrick Gordis at MaxxUAV EU & UK. I was a little sceptical to have this major surgery on my controller but may I say he done a great painless job and no blood spilt. He is very professional in his approach and was very prompt at answering my questions. So any of you UK & EU pilots want to boost your UAV visit his website. He's brilliant surgeon on controllers.
