Last year i was running the Tekin with a Speed passion 13.6 motor in our stock 1/12th class and i never had the right feeling from the car it was either all on or all off , i wasn't happy ,

During the summer i decided to try the Tekin out in my 0 timing touring car and + on -'ed it OOPS

so i now am using the Speed pasion GT2.0 , it has a built in booster and allthough it is a bit big and heavy it is really progressive and i am not a great driver but i am only 4/10ths off the lap record at my track

another plus point is i can program without the laptop (but it is always at the track)
