Honestly I would go plastic at first because if you ruin a spur gear chances are your motor moved thus causing the spur gear to get chewed. The way to check your spur gear mesh is to use a pice of notebook paper folded into two and use that as a spacer between the clutchbell and the spur gear. Then you would tighten your engine bolts down in a cross pattern. Then remove one at a time and apply loctite. YouTube is your friend for a better explanation. Some will argue that a steel spur gear eliminates the weak point in a tranny but I've never had a problem. If you do get a steel spur gear you're going to need a hardened steel clutchbell to go with it.

id go with the Robinson racing spur gear (hardened steel) just make sure you have a good mesh as stated above.

So i fitted my new spur gear took it out tonight to see if was ok have a problem if i hold truck in the air it throtles fine but 2nd gear dont seem like its kicking in when the cars on the floor it moves very slowley but engine is revvin up and not moving asiff something is slipping? A guy in the model shop told me to be carefull of a washer when changing i dident see one i was taking apart very carefuly but once i finished clearing up the work space i see a washer but wernt sure were it came from? Help please

I just inspected the spur gear I've noticed with the wheels on the floor if i turn the spur gear obv it turns but were the wheels are on the floor if i turn it with force it still turns like slips? Is that the problem? The washer i found had a hex in the middle can this be from the spur? I can tighten the nut on the spur but the spring is fully closed and have a lot of thread on the end and lookong at others they dont ill try upload some pics

As you can see in the bottom engine plate thats the washer i was on about

Think you found your problem buddy. Yes the hex bushing goes in the spur gear.

Sorted now guys i looked at my old spur gear and the was a gold washer type thing in it haha its fine now! The video on hpi dosent show u taking this out or its me just being blind thanks

I think the factory recommended setting for the spur gear nut is to tighten it down until the spur gear spring is completely compressed and then back it off a half a turn.
