Johns car analogy is correct, my dealer charges U$100 to look at the car. Even if you don't get it fixed you're still out the U$100. 
Are you telling us that you expect to pay for a quotation to provide you a service. Practice’s such as this is a blatant rip off of consumers, look for a new service provider, its no wonder business is in bad shape.
Having read hundreds of posts in this forum and the complaints about RC service providers, it’s a fairly clear choice to use Hitec equipment, suggesting that HiTec is charging their customers a premium to cover their excellent after sales service is utter crap, if they were doing this they would price themselves out of the market or the other manufacturer’s are also charging this premium and just not providing the service they have factored in, simply put a rip off and sub standard customer service.
