Thank you
With a spool you loose steering so zero or 2 degree hubs are needed. Also a shortened the camber links in front.

JAZ406 !!!!! Thank you very much!!!!! That is exactly what I need to know.
I have never used a spool and I run on a small track so I would like to avowed braking my car to much learning how to drive with the spool. It didn't go well trying the oneway for a couple weeks but I learned a lot and had fun doing it.
Thanks

Never cared much for a spool on carpet, I would rather run a diff/diff on a pro4 for the carpet, I had a carpet track and I ran a pro4 for almost a year (it was fast) I had problems with durability using a spool..ring gear broke..a lot, and no i did not hit things....I practiced a lot..probably 15 hours a week at the minimum. I was using a BMI 3mm chassis and top deck..you can make a Pro4 really turn in and really stay locked in..For Carpet I was running the Pro line Nemesis body (on rubber tires) best body I tried for a small track..(track was 80 x 45). Most of the set up stuff depends on how you like your car to drive/feel..not every driver likes their cars the same..start with a base set up and go from their..

Default SPOOL VS ONE WAY

I like the one way for carpet, We have a 75 x 45 track and the one way is the best in my opinion. I used a spool and the main drive gears broke and the pins
wore the spool down too fast. If you can make the one way work you'll be money ahead.

On page 30 in your pro4 instruction manual it tells you what you will get with more or less caster. I think you should get some extra 4deg blocks, you will brake more.

I seem to be braking HPI ball studs, is anybody using titanium and are they and stronger ????
Thanks again Guys for the help.

Less cater (i.e. 2 or zero degrees) gives you more steering at the start of the corner but less stability and cornering out of the corner on throttle and straight line stability is less.

Are they still making and supporting the pro4? I have been out of the scene for awhile, but I've always been an HPI fan.

You can still get everything you need for the Pro4 from Tower Hobbies and many other places.

I put aluminum steering knuckles on my Pro4 and did not brake any C hubs for more then a year. I put them on my HB Cyclone and same thing. You can get them from RC Market and many other thing at a good price there.
I would get HPI or HB parts, many of the parts on the Cyclone are the same, but you can try 3-racing also.

Try Jet Racing. The bearings will be really tight when you install them but they're strong and work really well. Jet Racing sells them in three different colors (purple, blue and black).

Hi all,

Just ordered some diff plates and both the thrust balls and the nitride differential balls (http://www.rc-edit.com/products.php?kit=4&lang=en) to rebuild my diff, what i am unclear about however is what diff grease to use.

I have lying around tubes of Tamiya Ball Diff Grease and Associated Stealth Diff Lube aswell as the HPI black grease for the thrust bearings, but no HPI white silicon lube.

Will i be OK to use the Tamiya/Associated lube in my diff and which should i go for please? If not i'll have to buy some HPI stuff.

Thanks in advance.
