Lead Weight For Lipo

Why do we need to change the weight limit? We could keep the one we have as it has been fine for the last 10+(?) years and we've had plenty of changes in equipment and materials (Nicad-NiMH, Brushed-Brushless, 40MHz-2.4GHz, Plastic-Carbon Fibre).

If A123 is the cell we should all be using, why aren't we? It's alright saying it's the future, but in a couple of years there will probably be a 'new' technology that we should wait for, but wait that will be superseded again so we should why for the 'newer' one, and hence we will always be on NiMH cells.

Lipo was the 'new' technology a couple of years ago for cars, it's now in mainstream-ish use and has got to a stage where it is safe (hard case) and the right size to drop in to 99% of cars.

At the minute Lipo is (over NiMH) everything you mention A123 is, so why not use that whilst we can, it's got to be better than NiMH. Then when A123 become an option for cars and people are using it we can look at changing the rules for that.

Or maybe we should wait for hydrogen power to come to our cars, as that is clearly the future.
