Guys Mark says it best when he calls local sponsorship target marketing. If you have a chassis sponsor, you run their cars and try to get others to run them too. Same with motors, esc's, batteries, etc. Part of the sponsored persons role is to promote that product. I have sponsors because I know how to market and can help get more product that I believe in out there. RCHR took on some Speedzone USA batteries after I talked to Mark for a while. Great batteries at an even better price allowing the shop to make some profit. That's the goal, get the name out there as much as possible. The shop sold through all but one battery, I did my job.
