FJ,
I can only comment based on my own experiences with jack Devine and from what I have heard from others. He's not a bad guy to talk to but he is dishonest as the day is long and has about 1 dozen modelers still waiting for kits they pre-paid for. I was warned about him but did not heed the advice from others who he had screwed. I'm still waiting for a JD kit that I pre paid for over 8 years ago that he never delivered. Others will tell you the same so I'd steer clear from this guy if I were you. There are other R2 kits on the market that fly much better than his does anyway.. Just my 2 cents.. paul
