I used to race at MHOR, but I haven't been there in 5 years. What's it like these days? What's the most popular off-road class and is lipo allowed? I really liked the racers there, but the small track and poor customer service got a little old.
PS. I charge my expensive IB4200's twice per race day and they actually seem to have more punch after the second charge than they do after the first charge.
