RDX Phi magic VIII: The all improved RDX Phi Diff - #79680:

Corally introduces an all improved RDX Phi differential (#79680). This new improved diff ensures long lasting super smooth trouble free diff action.

1.) The new diff uses 18 x 2.5 mm chrome balls (#1015) which run on large super hard diff washers (#79684). This combination guarantees to handle higher torque required for today’s brushless racing.

2.) The thrust bearing has been replaced by a special flanged ball bearing (#1125) which provides super smooth low maintenance thrust action.
3.) The diff uses the black anodized aluminium M4 (#1257) Nylock Nut for fine and trouble free adjustments.
4.) The new optionally available 7 mm hex graphite diff nut

wrench (#79685) will make adjustments even easier. Also even if the diff is already installed in the car.
5.) The new short (#79681) and long (#79682) outdrives have larger flanges for better and tru support of the diff washers. These also cover the diff balls and help prevent dust or other dirt from intruding and minimizes rebuilding of the diff.

RDX Phi magic Part IV: Improved RDX Phi Clamps – (#79708A - #79712A):

Especially on circuits with rigid borders such as on US carpet conditions, these newly improved design of the RDX Phi clamps might come in handy. These new clamps feature countersunk screw holes to allow the use of an extra screw for fastening the couplers much tighter, to avoid dislocation due to trauma during racing activity.
Use clamps for adjusting anti-dive, anti-squat, toe-in, car width, roll-centre,…you name it.

Three new entries in SP12X WC parts (#75956, #75958)–
one is also compatible for RDX Phi (#79274)!:

To enhance the SP12X WC front suspension, Team Corally offer tuning parts such as the Lower A-arm spacers in graphite (#75956) for ride height adjustment and Cross Brace in graphite (#75958) for greater stiffness.
Also a new type of 43 mm duraluminium turnbuckles (#79274) have been specially manufactured for use with the SP12X WC front suspension. They can also be used for the RDX / PHI centre steering option.

Change of color – RDX Phi center steering lever - #79256B:

The color of the steering levers have been slightly changed from brownish dark to bluish light, so if they are combined for RDX / Phi like in #79256A, it looks rather strange. But since RDX Phi only uses center steering, Team Corally decided to introduce a center steering lever #79256B:

Part#	Item:
79256A	RDX Phi Steering lever set- with all holes threaded M3 – Duraluminium
79256B	RDX Phi Center Steering lever, threaded (1pc.) – Duraluminium

New thickness (2.9 mm) for RDX Phi Topdeck – #79858:

If you want to adjust your RDX Phi with different thickness of graphite parts, the Team Corally 2.9 mm thick RDX Phi Topdeck is a way to go. Check out the Phi (the perfect number, 0.1618) – sign engraved on the Topdeck! Just be careful if you try it out on a 3.4 mm thick (#79839) chassis – the double thick combination might collide with the batteries.

Part#	Item:
79837	RDX Phi, Chassis – 2.4 mm Graphite (STD)

Battery Strap for RDX Phi – #79863:

In case you don’t want to fasten your precious batteries with sticky straps that make the beautiful stickers (from matchers) on the batteries looking messy after few rounds, you are more then welcome to use the good old fashioned Team Corally battery strap for your RDX Phi (#79863) to fasten your batteries neatly. Well, even if all the faster guys use the dudely straps, who cares?

RDX magic Part III:
The ground breaking revolutionary RDX Phi Diff with NUT – (#79690 - #79694):

How about a Diff fastened by a NUT? No more breaking Screws!
So the revolutionary construction of the RDX Phi Diff is enjoying the great moment of writing history before anyone gets the chance to copy the technique. Here are some facts:

Large Thrust Bearing, same as in SP12X
Super Lightweight
It uses M7 Diff nut, 9 mm Hex for diff adjustment instead of a diff screw.
Unique Output Shaft design - Duraluminium

Usually the diff is always used on the rear. You can choose either Diff / Spool / One Way in front.

If you use Spool in front, you will use more power. If you break, you will break on all 4 wheels, so easier handling. You will have a permanent drive train of all wheels (rigid front axle) if you break.
If you use Diff in front, you will have more resistance. You will be less sharp out of the corner.
If you use One way in front, you will break on 2 wheels on the rear. More difficult to handle, but higher efficiency.

Also a diff rebuild kit incl. diff nut is available as #79693.

Part#	Item:
79690	RDX Phi, Lightweight differential for front and rear (excluding pulley) – Duraluminium
79691	RDX Phi, Lightweight Output Shaft, Short – Duraluminium
79692	RDX Phi, Lightweight Output Shaft, Long – Duraluminium

RDX Phi magic Part I:
Changing REAR and FRONT Bearing Holders (#79698 - #79703):

Did you think we were finished with the RDX Phi magic? Team Corally are just getting started! You can change the rear bearing holders in order to get the following wheelbases in a flinch:

Long Wheelbase	264 mm
Middle Wheelbase	260 mm
Short Wheelbase	256 mm

REAR BAERING HOLDERS – CHANGING THE WHEELBASE:

To change the wheelbase has never been that easy and clear. So with the rear Baering Holders, you can change the wheelbase with #79700 / 1 between 256 mm and 264 mm. That means you can take them out, flip them over and put them in, and there you will have 8 mm different wheelbase than before in an instant. Just remember to use the right pulley / belt combo when changing the wheelbase (see RDX Phi instruction manual).
For example: If your rear is sliding away in the corner, thus loosing speed, you can lengthen the wheelbase to put more weight in the rear, to gain more balance hence become quicker in the corner.
If you want to get the middle wheelbase in between these two, just 4 mm difference, no problem, just use #79702 / 3 to get the 260 mm wheelbase, right before you know it.

Part#	Item:
79700 / A	RDX Phi, Bearing Holder, Rear – Left (256 / 264 mm) – Duraluminium (STD)
79701 / A	RDX Phi, Bearing Holder, Rear – Right (256 / 264 mm) – Duraluminium (STD)
79702 / A	RDX Phi, Bearing Holder, Rear – Left (260 mm) – Duraluminium (OPT)
79703 / A	RDX Phi, Bearing Holder, Rear – Right (260 mm) – Duraluminium (OPT)

(Note: the color of the bearing holders has slightly changed (blue grey) – to get the new colors, just put an A behind each numbers)
