I don't race at OC/RC so excuse me for butting in but I just have to reply to what Oldschool is saying.
I have been in a club racing some sort of spec for the last 10+ years and have been through all of these arguments.
The first problem is that racers that can't win regular classes come to spec classes thinking that will help them and it is just not the case. The best drivers still come out on top.
The other problem comes with limiting the cost. It does help cost when there are very few hop-ups or changes legal to make but when it comes to electric RC racing there are always guys that will figure out how to get more power out of any motor or battery.
Most spec classes we ran have used the trinity spec motor and spec battery.
In time guys have figured out how to get 20%+ more power out of the motor with spec brushes and they figured out that discharging about 20% out of the battery and imidiatly repeaking at 8-10amps makes the batteries come alive.
Hard to stop someone from doing either but it forces others to to compete and you are replacing batts everyother week.
Lipo's have helped that a lot as there is not much past warming them up to help voltage. There is a variance between packs but many clubs have settled on the orion 3200mah as a spec pack.
Now oldschool has posted many times how allowing lipos is starting down some slippery slope were we all end up with $1000 slashes but that is up to the local club or track to enforce rules and keep that from happening. All race classes have rules, spec is no different just tighter. He also talkes about making a racer spend $129 on a lipo. I for one have found some cheaper packs.
You can get 2 of these shpped for less than $83.
Now directly at Oldschool, you are never going to make freinds or get anyone to see your side, When all you do is rant and insult everyone for not being as smart and cool as you. You say you have had a slash for months and done tons of changes and hop-ups but you don't talk about what changes worked and what didn't you just put down others ideas.
