X-Factory - X7 New 4wd

55 posts in this topic

Sur le nouveau site X-Factory, il est possible de lire ceci:

The X - 5 was X Factory's first kit, entering the market in late 2004. Originally a conversion for the Team Losi XX4, it merges that car's awesome suspension with the extreme efficiency of the XXX4's single-belt driveline. The X - 5 brought on X Factory's first major-race success by winning the ROAR national title in 2005. Continued X Factory Family and Team development lead to the X - 5 Squared.

A recent problem with the main chassis mold has forced X Factory to discontinue selling the aging kit, though large part stores mean many drivers are continuing to campaign their X - 5's. Development of a totally-new X Factory 4wd car is currently underway...

Un nouveau 4x4 serait donc en cours!

Comment le voyez-vous? (Le voulez-vous?)

En cherchant un peu

1) The X - 5 Squared has been discontinued because of problems with the chassis mold. We can repair it and make great chassies, but the cost will be too high compared to expected sales. They haven't made xx-4s for a long time. As with so many other things, it's a matter of money.

2) We will continue to stock all X - 5 parts except the chassis. We actually just ordered some bodies. We will run out of chassies first. We discovered the problem when we hung the mold and began to shoot more. That is, our stock hit the re-order point, and we found out the hard way. We have excellent stock of all other parts, and will continue to stock the Losi parts too.

3) The X - 5 is my baby. I cried. Literally.

4) At this time, we do not plan to make another Conversion Kit.

5) We are racers and engineers. Ideas for new cars and improvements to existing ones dance in our heads constantly. A new 4WD car has been designed in our heads and discarded twice in the last four years. The inside of Elvo's head is an amazing place...

No complete assemblies have been in SolidWorks. Bits, parts, and sub-assemblies here and there all the time -- for us it's like drawing on napkins -- but nothing even approaching reality yet. SolidWorks is on my laptop in the pits...

6) We are at the very beginning of a new 4WD car now. As has been reported elsewhere, some testing has been going on since January, and several major mechanical principles have been tested and decided upon. That is significant progress. Over the next months we will be testing various specific drivelines to determine which iteration works best. If you look carefully, you’ll see new suspension ideas on those cars too. We will see what works.

7) X Factory has an absolutely dialed design team. Team drivers are selected as much for their help in design/development as for on-track wins. You just don't get more experience than Brian Kinwald, Ellis Stafford, and Elvo. You won't find more education than Tom Cockerill and Paul. Cyril, Phil, Alexander, Dan, Dan, and Mike all make salient points constantly. (We have two Dans.) E-mails flow daily, often two or three time a day, with copies and drawings everywhere. I can't keep up with it all.

X Factory began with a car that made everybody say, "Why didn't Losi think of that?" and proceeded to a revolutionary concept.

The new car will be fast. That's a promise.

8) But it all takes time and money. For a new 4WD where we make everything, on the market for Christmas 2010 is the very EARLIEST we can talk about.

9) We will release over the next few months a series of new parts designed to fit our cars and others too. If you've looked with care you've seen them in testing. These parts will be great new things that will make you faster -- our primary goal -- and will help move X Factory forward.

That's the Family concept. We make good stuph, the Family buys it, and that moves us to the next thing that the Family loves. We are in this thing together, having an absolute blast with our toy cars.

the first 4WD test beds are being put together now. We will be testing some new driveline ideas -- not shaft -- along with some suspension geometry ideas. If it works out at all as we have planned -- no major bugs -- the first serious public appearance of the test bed cars in the U.S. will be the MidWinter.

First serious runs outside the U.S. also in January at two races in U.K., the Petit and the Indoor Finals. On both sides of the pond the test beds will probably be at various club races before that, but will be under wraps as much as possible. If everything falls perfectly into place, (When was the last time that happened in an R/C development program?) production in around a year.

There really is not anything for you or us to talk about now. Another 6 months, maybe.

je confirme pour l'instant les protos seront fais maison ( normal ) sur base de X5, par contre rien a voir avec un B44 ou autres, transmission normalement a 2 courroies, les masses seront normalement centré comme sur mon X5 au CF de pertuis, mais plus au centre(saddle plus raproché et moteur quasiment au centre du chassis). en tous cas ils font du bon boulot, je leurs souhaite de nous sortir un beau 4wd avec une bonne transmission.

X Factory lead engineer and team manager Paul Sinclair was at the CRCRC electric club race Sunday doing some testing on a 4wd car. Paul indicated that the car he was running is a test bed for evaluating new ideas and that it will not resemble any vehicle that might make it to production. With many prototype parts hand crafted in the X Factory shop, the test bed will allow the X factory team guys to work out some of the details for the new 4wd buggy on the track. Paul said he plans to make a handful of the test vehicles to allow their team drivers around the world to contribute to the design process through track testing. He said their plan is to develop a stand alone vehicle as opposed to the conversion kit format for which X Factory is well known.

The test bed was constructed from a carbon fiber reinforced chassis which was spliced together from two existing 4wd chassis to allow wheelbase evaluation and also to provide a blank canvas from which to work on. True to X Factory form, they seem to be working out weight distribution (with a perfectly centered motor) and transmission arrangements first and plan to work out the suspension arrangements following. The car Paul drove today was belt driven, and one order of business for the day was testing out some new belts.

On the track the test bed car looked quite good. I got some pictures of the car in action but no body off pics by request. It will be interesting to see how this car develops over the next year, and big thanks to Paul for sharing this information.

Wais...

Pas plus tard qu'il y a 3 semaines j'en ai discuté avec Ellis... Il aura un proto pour avant le début du championnat national (faut pas déconner hein, il est pas fou au point de rouler en national avec un pred'). Mas surtout, il m'a dit texto qu'il ne faudra pas essayer de regarder de trop près sa voiture car elle ne ressemblera certainement pas à ce que sera la voiture de production.

Donc vous foulez pas trop les gars...

perso, je ne regarde pas pour savoir ce que sera la production, mais juste pour voir ce qu'ils explorent...

Par exemple récemment j'ai été ravi de trouver des photos de proto de XXXS, avec des cellules usinées et double plate CF. Ça n'a qu'un rapport assez lointain avec la XXXS produite mais c'est sympa de voir la genèse d'un modèle.

UuuuuuuZZZZinées ... Moi aussi j'adore voir la genèse d'un modèle. Je crois que le nouveau 4wd X Factory sera un kit complet et non une conversion.

XFactory 4WD prototype

Ellis Stafford wasn't doing this well in 4WD last year and with the widely publicised discontinuation of the XFactory X5 4wd buggy - what exactly was Ellis using?

The Xfactory guys were given free reign to run any 4wd chassis over winter to pick up ideas and help develop the next generation of XFactory 4wd - something that clearly seems to have worked since the guys had two new prototype test-mule chassis at Talywain to get some feel for their design concepts.

It has to be said, the guys were very reluctant to allow photographs but we arrogantly snapped away anyway whilst agreeing to mention just how early these prototype cars are - and if the concept doesn't work (which, it does to be honest) the final cars might well share no design elements with these early test cars.

From the outside, these new XFactory development cars are just an X5 - and even looking from beneath you'd be mislead by what appears to be an X5 chassis. The chassis is in fact hand-lengthened by 10mm over the old car which itself was shorter than most. The drivetrain itself is entirely new and uses two equal length belts to take power from the centre to either end. The centre itself is one of the most complex setups we've seen and a real contrast to the previous cars simple single-belt drivetrain design - doing away with all the hype about single-belt efficiency and moving toward the current situation where efficiency takes a back seat to overall balance, performance and usability.

First impressions are that the car has fallen into a bag of gears and some stuck - but joking aside, it's hard to see exactly what's going on. The motor is bang in the centre of the car and I saw several shafts, gears and pullies transferring drive to front and rear via belts as can be seen. Yes, I'm being deliberately vague, by request ;).

It was naughty to take these pics - if XFactory want, we'll take them down. But let's remember - these cars (2 here at Talywain and 1 in the USA) are just test cars with a lot of hand-machined parts bolted onto cobbled together chassis - any final car would look a whole lot different to these. Qualifying 2nd overall shows the potential of the layout however. We'll follow the progress of the cars during the year and report any developments on these early protos.

X Factory showed off its new 4WD car for the first time at the recently completed Cactus Classic. As usual, the testing was done in public but without fanfare, so few people realized what they saw.

These photos show the prototype X – 7 with a J Concepts body made for the B44. The production car will have its own body – this one works for now.

“I’m so excited about this car,” said Chief Engineer Paul Sinclair. “We don’t work outside the box because we have no box. The X – 7 is absolutely revolutionary. You have never seen a driveline like this, you have never seen adjustability this easy or quick. Working on the car is very easy; I can pull a diff, rebuild it, and have the car ready to run in 10 minutes.”

Clayton Easley, who drove the car in 13.5 Super-Stock at Cactus, said “The platform is definitely there. We have a long way to go, and we’ll have the details worked out in a few months.”

These photos show the car run out in Arizona. The blue body was used in practice, and Clayton and Paul’s own bodies arrived on Friday for qualifying.

Paul added, “We’re working very hard on this project. We will make almost everything on the car – it will be a complete Kit, not a Conversion. This is the first time I’ve actually designed everything on car from the ground up. There is a long way to go, lots of testing and development. Ellis Stafford will have my original race prototype sometime next week, while I build another for myself. It's much too early to talk about actual production dates, but we hope to have it on the market late this year or spring of 2012.”

Significant progress. The first prototype, run at Cactus and now in Ellis Stafford's hands, was actually the Gen 2 car, as in the second generation of C.A.D. At Cactus, that car had a number of small issues, common to any proto in its first run, and two major issues. The first issue was solved pretty quickly and the design team is unanimous that this issue is behind us.

The second has proven more tricky. About three weeks ago Paul and I spent several hours working on it, and for the first time we came up with a schematic that seemed to show what the problem was. Prior to that, we were floundering, so that was the breakthrough. Finally we had a diagram that, when manipulated, gave us something close to the results we needed.

Paul likens this to writing his master's thesis. He works on it every day, often 6 - 8 hours, and most days (not all) the thing got a bit closer to reality and bit closer to what is needed. So, about 10 days ago, Paul moved to C.A.D. of actual parts, even though we knew it wasn't perfect, just lots better.

Soon he realized what was wrong with the schematic, changed one item there from a circle to a slight ellipse, and -- bingo! -- the schematic matched reality perfectly. Now we were able to superimpose the schematic on top of drawn parts, manipulate the parts (and schematic) and have them follow each other precisely.

From there it was a matter of changing the parts and being certain they continue to match the schematic even though they have been changed. (I know that's a bit confusing.) There are a lot of clearance issues with other parts, so the parts in question must be changed to clear, yet still describe what the schematic says.

It's interesting, Stock, that you bring this up now. Paul worked most of last night (What did you do on Saturday night?) and we are now very close. It's just a matter of seeing that the parts clear and work in every possible situation. It does work at the difficult extreme. A few more checks and we expect to have the new parts designed.

Then, believe it or not, we will build Gen 5.2 of the X - 7 prototype.

I believe both Tater and Gould are correct! Engineering projects without deadlines are never finished, and nothing is produced. The finest imaginable product is still getting better on the comp screen.

On the other hand, we go where the physics and engineering lead us. Physics tells us, "This you must do," and engineering figures out how to do it. Note that Paul's 4-year degree is in Physics, with a minor in Math. The concept of the 4-Gear transmission is simple physics.

The Gen 1 prototype of the X - 7 had two major issues. One of them was fitting the electronics in, and we made a simple change that does not affect the physics but solved the problem entirely. 4WD cars have NO room! The other problem is more difficult, but we do think we've solved it; this one too a partially about getting everything to fit and work.

The physics principles, first tried on the test beds, are right on, both on suspension and driveline. It's a matter of doing and testing the engineering to make them work, and we now feel very good about that. Gen 5.1 may be on the machine late this week! Paul wants to drive one at the Bill Bridges race, Stefan needs one for the worlds, and Ellis won't go to the Euros without one before the end of this month. (See practice time above.) It's coming soon.
