My fantom helix v1 finally came alive after moving the motor fan 22mm away from the motor. Guys use to pull me down the straight before moving the fan, now I am pulling them bad...Hopefully they don't accuse me of cheating....lol....Go fantom....The same thing happened to me back in the 17.5t racing days with my FR-1 v1 in my tc4... Please be advised, 10mm is not enough even if the fan apparently runs fine...20mm or more if you don't want to bog down your Fantom motor...
