I am in Sebring, about 3 hours from Daytona, and about 1 1/2 hours from the Orlando area. Boggy Creek is an awesome track in Orlando, but from what I hear they are have noise and code issues at the moment. I hope they get it all sorted out because that is just an awesome track! As far as Daytona area, I'm not to sure, the only time I go over there is for the 500, or the 400.
There are a few hobby shops in Orlando, but I guess the biggest would be Superior Hobbies on the east side of Orlando, probably about an hour drive from Daytona. They hold monster jams there as well as on road races. They also have monster jam rc truck races at Race Rock Cafe in Orlando. I will see if I can find the links for ya.
