Steady Tigers!
1S systems do not put more stress on the motors than any other system. Whilst they have a higher current draw they have much lower revs. If you over-gear any motor on any system you will wreck it. On 2S, the motors rev higher putting higher mechanical strain on the parts. If you run 1S you put a higher electrical load on the motor. It's a trade of one set of strains on the motor for another. In both systems if you do not correctly gear a motor you will harm the rotor, but we have never, ever had a rotor explode on 1S whereas it has happened in 2S. I've never had a bearing replaced in a motor on 1S, but plenty were replaced at the Worlds on 2S. Different systems, different strains, different results, both able to toast a motor if incorrectly geared.
As for the cells you may think what you like but the facts are against you. Any 1S pack on the BRCA list will last you 200+ races or more even in a 12th Modified car before you could even call it tired. At club it will go even longer. Interestingly, the biggest growing electric classes in the last five years are the 1S classes - 12th, GT10, GT12 and F1 - in all corners of the world. If 1S was a cell-killer it would have got nowhere. You are entitled to your opinion, but for everyone else your summary does not reflect the facts.
Roger, I am sorry you find the Rules confusing. Here's it in a nutshell:
For National racing we run 13.5BL with 1S cells. For anyone organising meetings outside Nationals we have put in details of G2/4-cell and 21.5/2S to use.
The G2/4-cell needs no further clarification. For the 21.5/2S we gave guidance in two areas - a list of motors locked on timing so performance is closer, and using 'micro' 2S cells for which there is no BRCA list.
A car must be supplied as a rolling chassis, with wheels and tyres for £100. Whatever chassis comes with that car is what you use. If you want to modify the car and use a diff it races in GT12.1. If you just want to tune springs, dampers, etc. and run without a diff you can run on GT12.2.
Taking your point, I will make sure that such a summary is available on the BRCA website for 2013. I take issue with the 'mess' description as you are the only person to mention that since we started. I have had a lot of questions, but no one prepared to travel as far as you to avoid the class!! I'll try to make this a non-issue for you with the 2013 rules as I am mindful that you might be saying what others are only thinking!
To clear the rest up - we will have something on 2S classes more easily discoverable in the rules, and we will not be doing any more on bodies than presently in the Rules. Reverse can be discussed only if someone puts a proposal up for it, and the 2013/14 rules will be published next April after the EGM in early April.
If there's anything else, please come back an ask. It would be great if we could please all the people all the time, but we are realists! nonetheless, as I have said before, your feedback is appreciated and valuable. Please be part of any changes - things suggested on here will not make it into the Rules unless they are proposed at the EGM, discussed and voted on. Play your part to shape your class!
