I've ordered from them before and haven't had any credit card problems. I had a couple of fail safes and some screws for my Fantom engine on order with them for quite some time. The fail safes never did come in, so I had them cancel my back order for the fail safes and asked them to just send me the screws. I still haven't received them. I've emailed them a couple times to find out why they haven't sent the screws, but I haven't heard from them. Their customer service could be a little better (they're certainly no Tower Hobbies, but then again who is), but I think it's safe to give them your cc number.
