Before every Main we will perform tech inspections.  The cars are to be placed on the inspection table ready for inspection.  If anything is suspected to be out of spec the inspections can include tear down of the car as needed.  Once inspected the car is to be left on the table and will be put on the track by an official.

The following are the minimums that will be checked during tech inspections:

• Any class with board requirements will be inspected.
• Any fixed gear ratios will be verified (spur and pinion)
• KV testing will be done on all fixed KV motors
• Voltage on all Lipo to verify it’s at 8.4v or lower
• Batteries are correct type and mah (aaa)
• Proper Body type will be checked
• Weight will be checked for any minimum weight classes

Racer to Racer "Call out" option:

If at ANY point during seeding/qualifiers/mains it’s suspected that a car is out of spec, you may do a "Racer Call-Out". Request an inspection of a suspected car from an official and pay $10.  The racer suspected of being out of spec must present the car for a “call-out” inspection. Tear down of the car may be needed to verify any issues. (see definition of tear down)

• If the car is found out of spec, the part in question may be confiscated and the driver may be disqualified from that class or the entire race event depending on the severity of the problem.  Then, the $10 goes back to the person who did the call-out. 
• If they aren't any problem found the $10 is forfeited and is donated to the club/track/donation jar/etc. 

Tear down in the above scenarios, in order to inspect the board the car may be taken apart to the point the board can be lifted and have the fetts inspected.  The motor may be removed to be tested on a motor checker.  After a Tear Down it will be the cars owners responsibility to re-assemble the car.

• Truck:
  • Chassis must meet Spec Class rules.
  • Body must be a Golem or Marka lexan body, no hard body trucks.
• Trailer
  • Trailer must be a dual axle style Sleek RC trailer with 4 wheels/tires.
  • Weight in Trailers must be in the form of AAA batteries, no limit to how much weight but it must be in the weight trays built into the trailer.
  • Car being hauled must be a 98/102mm wheelbase and be a complete car with motor, electronics, hard body, wheels, tires, etc. everything except batteries.
