i heard about the ipd from you tiny_dealy! i read your post in the dynamite rr and looked at the link, then searched for it. i then looked at the competition: es-01-heard it blew out with a 180 motor, novak spy-too expensive, gm line-too expensive, quantum line-too expensive. i thought the ipd was a good mix of performance and price and since i use speedos with forward only in my 1/10 touring cars, i wont miss reverse. note i say the others are too expensive because i dont want to blow like 60-120 dollars on a mini speedo. i can do that with touring cars
