RPM vs. GPM

**IRunMERV** · 10-30-2011 10:54 PM

Which knuckles are better? RPM Knuckles or GPM Knucles? Which last longer and dont cause other parts to break?

**Petertje60** · 10-30-2011 10:57 PM

I'd go for GPM. Friend of mine just ordered them too because his RPMs drive him crazy (pillow balls keep popping out).

i had rpm, pillow balls popped out after a couple of weeks of hard bashing. rpm says to place them in boiling water to have 'em return to their original shape. i upgraded to gpm and they've been spot on ever since. no issues what so ever.
they are a forum favourite for a reason

GPM Knuckles + 2

Not sure if they are. You dont have to boil the GPM ones. Pro of the RPMs is that they are cheaper. Maybe not in the end if you add in the energy costs for boiling (just kidding on that one).

I meant the gpm as a forum fave

I have the RPM knuckles and the pillow balls have popped out several times from hard bashing

thats it, though i would remove that link, traxxas doesn't like it

**Radiner140** · 10-31-2011 09:00 PM

My Rpm knuckles never popped out before and I had them for a couple of months bashing or not, they work great for me but can't say a thing about Gpm

**Sir.Yilufa** · 11-01-2011 06:27 AM

I love the GPM CVDs.
They seems so solid and sturdy.
Anyone knows where can I get them?

**Jimmie Neutron** · 11-01-2011 10:56 AM

You can get them from Toyz, but; I recommend Traxxas "X" shafts... they are more expensive, but they are the only ones that hold up beyond a few packs. (unless these are something new and improved... got a part number?)

They look kinda heavy dont they? Wonder if anyone has tried em out

I haven't, but I know a few people have and no-one has been impressed. They look good but break quickly.

**turok** · 11-01-2011 02:01 PM

are the Fastrax the same as the GPM

**Jimmie Neutron** · 11-01-2011 04:08 PM

Part number??
Picture??

I hate to sound like a broken record, but without something to guide me; I haven't a clue what you are looking at.

**jimbo74** · 11-01-2011 06:49 PM

Fastrax looks a lot like GPM.
