Neale,
A lot of it comes down to two things. You have to have BRCA sanctioned motors and lipos to race at regionals, this has always been the case but from 2014 this rule is being enforced. There are a lot of people who have invested in non BRCA approved lipos and motors for example Hobbyking who are not interested in buying new electronics and are not bothered about scoring BRCA points.
With those two points in mind we are actually creating more racing as we are running the Clubmans series along side the BRCA events at Mendip so the non approved racers can still race and accrue points towards the Clubmans Championship. If we did not do this these non approved racers would not be able to race and therefore forcing a smaller turn out on race days which is no good for the membership or the club.
On regional days you have to make the choice but in the grand scale of things if you choose to race for BRCA points you would only be dropping two sets of points from the Clubmans Championship, you only need six to count.
As it happens at the first BRCA 4wd round at Mendip two weeks ago we had an extra heat of 4wd Clubmans due to the approved only equipment rule so better for those racers and the club turnout.
On a side note, in the past many racers have only raced for BRCA points at their own club. The points those one time racers achieved may have robbed someone who raced all the BRCA rounds of a valuable point that may have made them miss out on getting an F2, F3 etc so for the committed BRCA racers this is a better system for them to achieve better F grading.
Hope this clarifies things behind the general consensus of opinion.
