My experience with DP started out very good, well enough to get me to place an order the next day for the 1/4 scale cub. I spoke w/Dave personally on the phone and he was great to deal with. The kit arrived, less my instrument panel (back ordered) and a broken landing gear part. I called and spoke w/ Sandy at DP. It took a few minutes to convince her to send me a replacement part w/o first getting the broken one back, but she did agree. After a couple of weeks passed and no part, I called her again and inquired about the broken part and the back ordered instrument panel. She said the instrument panel was in and back orders would be filled but they were really busy getting ready for a show. What about your existing customers coming first? I guess they wanted to service future customers before taking care of paying customers. Anyway this conversation was right after Christmas and still no replacement part or instrument panel. So much for service after the sale. Hate to have to make a post about this, but enough is enough, I should not have to call ever day to get what I paid for. Dave gets a 10, Sandy a 1, average is a 5 if I'm in a generous mood.
