I have both : DigiQ (got for 60$ with Special Controler) & iRacer (got for 15$)
iRacer has 1.2V bat vs 2.4V DigiQ
iRacer is 1mm shorter then DigiQ
iRacer is slower then a 2.2 Bit ... DigiQ is faster then 3.8 Bit.
iRacer range is shorter then DigiQ ... and has also little bit more delay ... already DigiQ has delay from controler to car.
iRacer is a crap ! DigiQ is insane fast but crap ... get a Bit ... if you mind about money take a LXX for 10$ !
Best car: Bit-Booster or find this car:
