i saw some test showing discharge curves of lipo versus nimh any one know where on is or if i have got my facts wrong?
The only on track advantage is the weight. Often times people who try the LiPo for the first time swear its "faster" or "punchier", and they attribute this to extra voltage. In reality, its much simpler than that...if the car is carrying less weight, it will take off faster.
So if they want to maintain "fairness" (if there is a such thing in R/C), then just have a weight limit. That way, the LiPo and NiMH runners will all have to weigh in at the same thing and all the advantage of lighter weight is removed.
If they still wont allow you to run it, ask them how "fair" it is that some guys have $80 packs with insane numbers while others can only affoard budget packs with crappy numbers. If they still have a problem with you running it, I say find somewhere else to race.
