Would are the advantages/disadvantages of using both the narrow and normal hex in the rear.

Not sure what others have experienced but I noticed a bit more rotation in turns with narrow rear hexes. Feels good on small/tight tracks.

From the Hudy Setup Guide:

Effects of Rear Track Width

Wider
• Increases rear grip at corner entry
• Increases high-speed on-throttle steering
• Use to avoid traction rolling

Narrower
• Increases grip at corner exit
• Increases high-speed understeer

Quick question. I am going to be replacing all of the ball ends and balls in MP9. My questions is, should I use the Hard Anodized 7075 balls or the Hard Aluminum Balls. I attached the part numbers to links below. Thanks

Hard Anodized 7075 Balls KYOIF464H - http://www.amainhobbies.com/product_...Flanged-Ball-2

or

Hard Aluminum Balls KYOIFW417

I'm thinking 7075 indicates which type of aluminum, I think that is a durable type. The other just says "hard" and might not be as durable.

There is actually no difference in the two part numbers' material or finishing, they're just two different parts entirely. If you want to replace all the balls on your MP9 with the hard anodized version, here's the list:

92653H - 5.8mm Sway Bar balls hard
IFW416 - 6.8mm Steering Link balls outer hard
IFW417 - 6.8mm Steering Link balls inner hard
IF462H - 5.8mm Servo link balls hard
IF463H - 7.8mm Rear Inner link balls hard
IF464H - 6.8mm Front upper arm balls hard
IF465H - 7.8mm Rear Outer link balls hard
W0201H - 5.8mm Lower sway bar link balls hard
W0204 - 6.8mm Lower Shock end balls hard

When Kyosho uses "Hard" in their product descriptions, they're referring to the Hard Anodizing performed to finish the part, not the actual hardness of the aluminum (anything that's anodized with the gold-ish color is hard anodized).

Notice any differences in the wear between the standard ones and the hard anodized ones?

I figured they would last longer, I just wondered how much longer.

I don't run the standard ones so I can't really comment, other than they're steel and these are aluminum, so the softer aluminum will tend to wear a bit faster but you're splitting hairs at that point. I'll take the weight savings all day long over the maybe 5 min more runtime the steel balls may give in the long run.

Hi Sean, whats the go with the hard rear arms? I noticed that not many top drivers are using them. Are they worth buying?
