I don't fix the old ones. I sold them all. I do order a lot of parts for my rappy 70, but it tends to be more upgrades than anything. I was just going through some statements last night and didn't even realize I had ordered 3 times from heliproz last month, all upgrades, and always $150 to $200. Gotta watch that. Quit upgrading the darn thing, I could get a new one! Then I would just have to upgrade that one though.
