j'ai retrouvé ces photos sur mon ordi, (source rctech certainement....)

le type a l'air d'avoir modifé la cellule arrière et retourné (?) l'axe intermédiaire pour conserver l'équilibre en 5 éléments... et puis la direction aussi... ?

Discutons !:carre:

ça n' intéresse personne ? moi si, au cas vous auriez pas compris... :youpi:

j'arrive pô à voir comment il fixe le moteur....

Seen on the pit table of Corally team driver Marc Fisher, who is present at the 4th round of the European Touring Series in Andernach, Germany, we got an exclusive look at the new prototype Corally RDX Phi. Due to be used by the factory team at the European Championships next month in Vila Real Spain, the new car sports all new geometry front and rear and a more conventional shock absorber mounting, mounted to the rear of the rear shock tower and not to the front as on the current car. Designed to cure some problems that affected the cars handling, Fisher is getting used to the cars settings in order to gain more knowledge prior to the Europeans. Also new on Marc’s car is the GM Genius 120 brushless speed controller that has a much smaller footprint than the previous versions and comes with a built in cooling fan.

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 The thrust bearing has been replaced by a special flanged ball bearing (#1125) which provides super smooth low maintenance thrust action.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.

Yop,

Ils ont montés toute la triangulation du 416 dessus?

merci

Pourquoi tu veux qu il monte une triangulation de 416 alors que celles de chez Corally sont deja excellentes voir meme exemplaire en terme de dureté et de qualité? Mais c est vrai que y regardant de plus pres ca y ressemble bien sur la nouvelle version.

bonsoir

je viens d'acquerir une rdx phi d'occasion.

j'aurais deux petites questions....

1) la courroie av me parait extrement detendue malgres une apparence somme toute excelente(pas de craquelures ni dechirement).

est-ce normal sachant qu'il y a un spool et que la courroie ar est elle bien tendue(ni trop peu ni pas assé).

2)je possede des ib 3600 et ils passent juste juste sous la platine de renfort.

est ce normal et si oui comment y mettre des accus de plus forte capacité donc forcement plus gros.

merci pour vos reponses

@ tato

ps:mon 1er chassis a courroie

problème numero 1 resolu,il me manque le tendeur de courroie(enfin le support).

oh ça ,ça va claquer je le sens bien!!

RDX PHI '09 SPEC

Corally

Seen for the first time at the annual DHI-Cup in Denmark the 2009 Corally RDX Phi is finally here. Based on the successful RDX Phi platform the ‘09’ tourer offers the same versatile layout the previous car did but is specially designed to accommodate the ‘bulky’ LiPo hardcase batteries that are becoming more common these days in various racing classes. Most noticeable are the newly designed and higher bulkheads, new suspension mounts and last but not least a wider chassis plate. What else has the new Corally RDX Phi 09 to offer?

By Sebastian

Front

Those who are familiar with the Phi range of cars will instantly notice the differences between the previous RDX Phi and the 09 version. First up, the 09 sports taller bulkheads to raise the topdeck by around 7 mm to make way for hardcase LiPo battery packs and power cables. The next and probably more important change are the new suspension mounts that do away with the complex clamp and pivot ball assembly and substitute it for a more user friendly plastic block/pivot ball construction. Kick-up and toe settings are adjustable via shims/different blocks but these are not part of the kit and therefore have to be bought as option parts. Compared to the ‘older’ Phi the 09 model has 1.5 degrees of toe-out with the supplied wishbone mounts whereas the predecessor had 0 degrees. In theory the 1.5 degrees toe-out setting should scrub a bit more speed when going into corners.

New on the 09 version of the Phi TC are updated ‘narrow’ (#79630) plastic steering blocks. They are less beefy than the usual #79280 ones and offer two inline holes for the steering ballstuds rather than side-by-side ones as found on the #280. Also new to the Phi 09 are plastic 3 degree caster blocks that replace the aluminium ones (Please see also our ‘Performance Tips’ section at the end of this review). Unchanged from the older car is the front one-way differential that is an ideal setting for fast to medium (outdoor) tracks. Optionally a lightweight Delrin spool, an aluminium spool or a ball differential can be fitted. On a side note: we tested the #01620 ‘Euro’ version of the RDX Phi 09. A special ‘US Carpet Spec’ edition (#01621) with thicker chassis, harder springs, different C-hubs and a front differential is also available for those who want to experience the mayhem of running touring cars with foam tires on tight US style carpet tracks.

Back to the euro car. Front geometry is changed in terms of toe settings but also the shock stay has undergone a bit of an evolution, now showing four instead of three mounting holes for the oil filled shocks. The holes now sit closer together allowing for an even finer tuning of the set-up. Even the mounting holes for the upper camber links have undergone a bit of modding as they also sit a bit closer together and went a couple of millimetres towards the outside to make for overall shorter upper links giving the chassis less roll in corners. Just behind the front one-way the new centre point steering assembly is located. The previous Phi offered this set-up too but the 09 car now sports a plastic lever instead of an aluminium one and also has horizontally mounted steering link balls to fine-tune the steering characteristics.

Middle

Corally’s new RDX Phi sports a 2.4 mm carbon fibre chassis that has undergone a huge evolution compared to the previous car. The new chassis plate is around 10 mm wider on the widest part and now has a ‘full surface’ design underneath the wishbones. Where the old car had 70 mm wide ‘ears’ for the droop screws the new plate has gotten rid of these ears/wings by having material remain in front and behind the wishbones. This is because the new pivot mounts for the wishbones attach here.

When looking at the chassis plate one could see that the 09 version still shows loads of countersunk screw holes to add brass weights, change wheelbase settings or add different battery mounts but the new plate does away with the square holes for the old design Corally brass weights and made way for the new style brick design ones. They are also meant to ‘only’ mount behind and beside the battery pack instead all the way along the centre line of the chassis as seen on the older Phi. The locating holes in the 09 chassis plate show what’s important when using LiPo batteries: to get the weight towards the centre line of the chassis and especially towards the rear, as the cars might be too light around the back.

The design of the rear bulkheads is quite similar to the previous car but is adapted to raise the top-deck. Again the fixed layshaft construction is used having been introduced with the original RDX range of cars. The layshaft slides in a slotted hole each side of the bulkhead to make for an easy change of different front and rear belts to accommodate different sized pulleys that can be used to alter the internal ratio, which may be helpful if you want to race the car in stock classes. Corally offer a wide range of pulley and belts and the manual refers to all parts needed to do the mods. The supplied 78T 48dp spur gear is sandwiched between the aluminium centre hub and a aluminium support ring for a true running gear and minimal transmission losses. Standard with the standard Phi 09 are 21T centre pulleys and 42T one-way/differential pulleys.

Rear

To handle the brutal power modern brushless motors offer Corally invested in an updated rear differential with 18 2.5 mm chrome diff balls in combination with thick 26 mm diff washers. The 18 balls run on two different orbits and the diff is designed without the usual and often fragile thrust race making for an easy to build set-up. In combination with the supplied Corally diff grease the item has a reasonable amount of lock upon building.

As with the front, the universal CVD driveshafts are equipped with plastic outdrive savers to avoid damage on the rear aluminium outdrives. New to the 09 model are plastic uprights with vertical ballstuds that do away with the machined aluminium/horizontal ballstud items found on the previous car. The rear shock tower is modified the same way as the front item: it sports more, and closer located, holes for the shocks in combination with new camber link positions.

Wishbones of the medium compound ‘35’ type are standard as well as the pre-assembled aluminium threaded shocks that only need to be filled with the supplied shock oil (unless you know better and just switch to the recommended oil for your track). Oh, we nearly forgot: the new rear shock tower also houses the body posts now. Corally did away with the bulkhead mounted brace and now uses shorter ones located on the shock tower. The result is a more precisely mounted body as shorter body posts are less prone to ‘swing’ like the longer ones found on previous RDX’s.

Like the front, the geometry of the rear was changed a bit. Whereas the old RDX Phi shows 2.0 degrees of toe-in, the 09 car has 2.5 degrees now. Also the wishbones sit around 1 mm closer to the chassis plate which in theory increases rear end grip. Roll-centre is adjustable via optional shims under the suspension mounts and by changing the upper camber links. Toe-in is adjustable via different pivot blocks (Corally #79728).

Finish

Our review RDX Phi 09 was topped-off with a Mon-Tech Nazda 6 body painted by Vesa of V-Dezign. Power came from a 5.5T Speed Passion Competition 2.0 motor, Team Orion Race Spec 3800 LiPo and one of the new LRP SXX TC Spec speedos. To make way for the long cables of the speedo and servo we slid the servo mount brackets all the way to the front but this is something you have to decide on your own – others may wish to have a more rearward located servo.

Track test

We tested Corally’s RDX Phi 09 on a large, and very fast track. We geared the Speed Passion motor 22/78 at first which proved a bit too long as LRP’s SXX TC Spec speedo generates a lot of RPM so we went down to 20/78 which gave an overall ratio of 7.8 which was ok. Our tyre choice was Much More Racing’s 28 deg Sweep rubber that was a good and consistent choice for the warm asphalt track.

Next thing was to set-up the SXX TC Spec speedo according to LRP’s new SXX setting guide for large tracks to 1/5/1/1 but after the first couple of laps we switched to 1/4/2/2 as the level of grip available did not allow for the aggressive ADPC mode ‘5’. We also gave the suspension one millimetre more droop at the rear to make for a more stable back end coming out of the tighter turns. We also lowered the suspension 0.5 millimetres to 5.5 mm in front and 6 mm up rear. Now the ‘09’ felt even better. Thanks to the front one-way, turn in at the beginning of corner was very good, the chassis felt very precise with good grip. It’s hard to compare the new Phi 09 versus the old ‘NiMH’ type car as we drove, both with different set-ups and overall weight, but we had the feeling that the Phi 09 feels a bit more precise.

Dutch Phi-nomenon - Corally RDX Phi 09

To generate a touch more grip we moved the front shocks one hole in and now the car felt absolutely dialled. The chassis had a very good balance and was a pleasure to drive. With the 7.4V LiPo battery and 5.5T motor top-speed was insane but although traction was quite high the rear differential held up very well. After five packs we very slightly sanded the diff washers with 1000 grit paper and a few drops of WD40, then cleaned everything, reassembled all parts and the differential felt like new again although it is non-sealed and we ran it outdoors.

Conclusion

Corally’s RDX Phi 09 is a sensible evolution of the previous RDX with a future-ready chassis technology making it easy to run powerful LiPo batteries. Performance as usual is top-notch but we do not understand why the car (still) has such sloppy wishbones that wobble on the inner hingepins. In our understanding of a good performing high-tech car at least the rear suspension has to be rock solid to guarantee maximum performance and drivability. Good thing is that this is the only real negative point and that it does not seem to hurts the car’s overall performance too much (see Performance Tips section).

Performance Tips

Suspension – The first and probably most important tip: get rid of the slop in the rear wishbones. We hate to say it but from the box the suspension arms show radial play on the hingepins. You can overcome this a bit by adding very thin spacers (thicker Delrin style ones are supplied) on the hingepins to stop the also possible axial play. By shimming the wishbones correctly the wobbly feel can be reduced. You can go as far as dripping some CA glue into the opening of the wishbones and scrub with a reamer after drying to do a near perfect job. We only added some washers while testing the Phi 09 and noticed a slightly more precise back end of the car but laptimes where not affected so we think reducing the amount of play in the arms is mainly to please the drivers/mechanics.

Battery connectors – When soldering male connectors to the speed control please make sure you use plugs with the lowest possible height. On the negative pole you see a current connector with some sort of additional ring to solder the wire on. For the positive pole we used one of Corally’s ‘Corally Plugs’ (#1634) that is of a lower height so the wire is nicely routed between the battery and the upper bulkhead. If you would use the taller connectors the wire and plug would interfere with the bulkhead.

Pinion gear – When choosing your pinion make sure you use items with a low as possible, or hidden, grub screw otherwise the screw can catch the belt.

C-Hubs/Castor blocks - The new blocks come with steel inserts for the fasteners and additionally offer the possibility to adjust the steering block height with the help of three nylon washers. As a rule of thumb it can be said that running the steering block high means a more aggressive steering and running the steering block low means a less aggressive steering. Please beware that you change the bumpsteer setting as you move the blocks up and down so you may need to add a washer or two under the outer steering ball stud to keep bump steer at a consistent level.

Why not turn the battery around and put the terminals at the front?

2. Sebastian - August 13th, 2009 at 11:21

Hi Gareth,

many thanks for your comment. Of course you can also turn the battery around and put the terminals at the front to use taller connectors. We opted to route them towards the rear as this way they face away from the receiver. As you know sometimes the power wires can generate glitches if located too close to the receiver.

Sebastian
