I have an FW05S with 2 speed transmission. Everything works great but occasionally as im accellerating out of corners something slips and the car revs right out and it loses all its drive power, this only lasts a few seconds before it seems to catch again and i can keep driving.
I know it sounds like the gear mesh between the engine and transmission is stuffed for sure, but i know for sure that isnt the problem.
Anyone else experienced this before or anyone with any suggestions please let me know as its starting to really annoy me. Ive taken it apart a few times and cant see anything obvious.
Any help is much appreciated,
