Hey c1 racin; Thanks for the info.....but the New Upper-Deck is Item # 73109.
-The 1st Pro 4 Hara Edition came with the Upper-Deck you listed. --The 2nd Pro 4 Hara Edition came with a New Upper-Deck(73109).
-----I have a Pro 4 that I turned into a Hara Edition.....Ha Ha!. . . . .I just don`t have the extra Suspension/Pivot Blocks.


Hey pocketr2004; I don`t use HPI Springs on My Pro 4. I use Tamiya Springs. Tamiya Springs are better(to me). . . . .I`ve tried HPI Sprngs on My Pro 4 and the Tamiya Springs made it run better.

Take Care

HPI Out-Done themselves with the Pro 4. To me; it`s the best Shaft Drive set-up(It`s somewhat better than My TB Evo 5).

When you put on the Hop-Ups; it looks Nice.

Take Care

Default It aint over...

Oh yea, don't think for five seconds that it's over. As soon as it breaks and stays above 50 degrees, I am coming out with the Pro 4, Mamba 5700 on 11.1. Fort Bennet field, be easy! I am going to be shutting down 1/8 scales in 20 minute heats! While they are refueling, I am driving and lapping. Best believe! Belts? Those are for holding your pants up!

You want a final drive ratio of roughly 4.2-3.9

Depending on track size using 48p gears get a 65 and 72 spur and a selection of pinions 48p 35, 36, 37 tooth.

One of the above should suit most med to large outdoor tracks.
If your track is small try the 72 or a 75 pitch spur.
