Ok so I got a traxxas nitro sport. And just bought a trx 3.3 racing engine for it. Now the problem is that the throttle for the .15 and the throttle for the trx 3.3 are different and I would need to convert the throttle control over to the spring one. But I don't know the circumference or measurement of the ball at the tip of the new throttle. Can anyone help me whose used or has this same engine.
