RCCrawler Forums - U4RC....KCRC Addition

I have heard some chatter about what format/vehicle types/track make up/etc that we are planning to run. If unfamiler with RC Ultra4 style racing, I would encourage you to check out the U4RC facebook page and/or U4RC section here on RCC (watch the videos). Additionally check out some of the 1:1 videos from King of the Hammers (the inspiration essentially).

With the blessing of U4RC, we will be using thier rules as a guideline. And though I personally hope that the 2.2 Trophy (and soon to be 1.9 Trophy) become the big draw.....I am fully aware this will not be the case at first.

I foresee starting out with basically a 1.9 & 2.2 competitor class, and
expand from there as interest grows.

Below are the current (Revised Rules 03/26/2014) U4RC rules that were established for the 2014 season.

Heat format: We will take the top two from round 1. Round 2 we will take the top two. We will do a LCQ the top 2 to get into the final. This will work for 4- 20 cars. This could change if we don’t have enough cars for a class or too many.

TECH: Checking of the car can either been done at sign up, heat race, or after the main. Cars that don’t meet the class requirements will result in a DQ and no points will be rewarded. People the can tech a car are has followed a U4RC official.

TURN MARSHAL: Everyone is asked to turn marshal unless you physically cannot do it. Turn marshaling is physical work and is hard to walk on the track. If you cannot turn marshal let us know at sign up. We also need track Marshals to watch the track to catch people cutting the track. Please when you are turn marshaling don’t be on your phone, taking picture, smoking, and drinking. Put cars back on the track in the tended direction of travel meaning don’t put the car on the track backwards.
