at my local club, in all the years racing, 4wd has always been low/non existant... this year, with brushless and lipo, they have outnumbered the 2wd's, as power is easy to get hold of now.
As with any battery technology, it moves forwards, performance will increase too, my cells are rated at 23C and 2C charging, but I never intend to find out if they will do 2C. Some cells I think, are stretching their performance figures a little, but the C raing really is all about grunt, and in the end, the good thing with off-road, is grunt has to be metered due to lack of mechanical grip. Where the issue comes in, is when people start cocking about and charging LiPo outside of the defined parameters, you get a voltage increase, hence why people are talking about voltage cappers between the cell and the esc.
But then, what do people do with NiMH's, we are told and recomended to charge at 1c... (4.2A) and I regularly see people charing at 6A, as it gives them a voltage increase, but it comes with a clause... cell lifespan.
As a racing organisation, you can constrain things with rules, but for the most of us, these rules would only affect us at regional level. In the end, the way I see it, if your caught doing dodgy things with ANY batteries, you should be asked to leave the meeting.
