Traxxas 3.3 question

[estep64]

Iam looking at the 3.3 engine and Iam just wondering what is the difference between the multi shaft w/ recoil and ISP shaft?

 

[Snook Man]

Multi shaft uses a threaded insert in the end of the crank for different applications.
W/recoil means the crank shaft has the pin for a starter shaft to use a pull, ez or roto start instead of a starter box.

The IPS crank is the standard crankshaft with threads for the clutch nut and it is grooved on the end for an e-clip to secure the clutchbell.
The IPS comes with or without the starter shaft pin, if you intend to use a starter system other than a starter box, you need the shaft with the recoil pin.

Yea I've got the ez start

So with a nitro sport I need the ISP shaft w/ recoil ?
