mid season review- after the 3rd race we will close any loop holes we missed. This is in an effort to keep the competition tight through as many different combination's as possible
Please remember the goal of this class is to bring into heads-up racing as many as possible people who have never heads-up raced, by keeping the class "entry level", inexpensive, competitive and fun
thanks marty chance
There are no scales at this track that's why there are no bolt on front end stuff k members etc. No way to make it fair for all makes.
Also the carb and nitrous jet size will make this a truly affordable class. would be kinda nice to race with a motor that does not cost the same price as a small house.
should be very interesting
