I have problems with my PV and send an email to HeliPal where I bought the PV. Actually I thought they was located in USA? But it came from Hong Kong - Asia To World Group Limited. Never mind, I got an answer from them today, and here is what they are writing: keep it as small and light as possible (just like a letter in an envelope) by cheapest airmail. ???? What? I have (with some extras) paid over $2000 and they want me to send it like that??? I will send it back in the original package (of course), but I'm wondering who should actually pay for the transport? I only had it for 10 days or so? ANd by cheapest airmail, that could take a long time. I'm sure it will be quite expensive but I will send it Airmail express.
