STAGE 2 REPORT
Short overview of GT rules and additional information.
The last version of the Gt rules can be found on the IFMAR website. See:
https://www.ifmar.org/wpcontent/uploads/2018/10/IFMAR%20GT%20class%20rules%20final%202018%20V1_1%20GBS%20corre
ction.pdf
Those rules are based on various discussions during 2017 and 2018. This class was meant tobe slightly different than the already 40 years existing 1/8th Proto cars. A car made with off-roadparts and drive shafts, low maintenance and rubber tires to get only small tire wear. Also thebody on the car should be something that can be recognized. Silhouette profile with the original
car must be visible. Originally the plan was to specify motor-specs with maximum timing andheight of the exhaust port, however this is difficult to check for technical inspection without
dismantling the motor etc, so we decided to use heath length and no refuelling as a way to limit
the engine specs and a maximum carburettor diameter of 7mm, in combination with 16% ofnitro. Also the first refuelling in a final is only possible after 7 minutes.
However this first GT event is now to be scheduled in January 2020 and due to the fact thateach bloc has used different interpretations (especially when it comes to length of heat,refuelling allowed and nitro percentage) of some technical rules we decided after someconsultation with countries/blocs and the organizer to make some small changes and additions.
Heat length will be 6 minutes, no refuelling allowed. For all finals first refuelling after 6 minutes
and second refuelling after 12 minutes. So watch out with heavily modified engines.
Bodies to be used, only those on the list with approved bodies, see: https://www.ifmar.org/wpcontent/uploads/2019/09/IFMAR2019bodylist%20GT8_V0.pdf
Same applies for mufflers and INS boxes.

Furthermore some additional information regarding the foam bumper in front. The foam bumper
minimum measurement is 20 x 200 (height x width) mm and the foam must be able to absorb
over an area of 20mm minimum, so do not lock the foam up between 2 plastic parts causing noimpact area.

Minimum weight 3500 gram, ready to run, no fuel inside
No Centax clutch, Clutch must use radial centrifugal shoes only in conjunction with Standard
parallel sided cylindrical clutch bell.
