Wow! Superclean install!

Looks really excellent :thumbsup:

everything is perfect, even down to the tires...

only thing... personally, I would loose the rear skit plate

[peetbee]

:thumbsup::drool::drool:

[Oliv996]

Thanks Chris :thumbsup:

Agree with you about the skid plate: I expect to mount it only when running on sever abusing tracks 'cause XX4 chassis bottom end is quite fragile where rear bumper is mount ;)

[Dalla]

Have you got any pics of the car without the lipos in, so we can see the detail of the brass lipo tray?

Also love to see more detail of the front wishbone savers. Do you use a custom screw into the hub?

Also like the rear Ali hinge pin brace and rear bumper holder. Have you done anything at the other end to retain the hinge pins?

[olefiloux]

Hi Dalla,

I will take some pics without LiPo in so that you will see the Manutech Racing LiPo weight balancer...

The front wishbone savers have been home made few years ago when I were racing X5. The screws are coming out of the kit but have been tapered so that same lenght are in the hub carrier. I will also post some pics ;)

About the rear hinge pins, they are only stopped by the rear bumper as they are in the kit.

Cheers

[Panic]

Excellent job, like the way you have soldered the wires from ESC to motor. :thumbsup:

[Gayo]

T'es top fort mec ! :thumbsup:

[Spencer Mulcahy]

I am really anal about the wiring in my cars this is fantastic mine looks a mess now LOL.:thumbsup:

[caciqueconnection]

Superbly clean, in my opinion one of the 4 most important things in a kit.

Reliable, tunable, clean...and fast, of course.

Hope you don't mind I use a couple of ideas :thumbsup:

[ace028]

WOW, nice job!!! I hope to make my cars as clean as yours!!!

Clearly you missed the biggest thing Chris. Sort out the length of the steering turnbuckle. Its like 10 turns to long. Other than that looks cool.

I wish we can those tyres and not just at the odd hot day at kiddy (ahhhh the good ole days)

Has it be put in a vacum box and stored for the rest of your days?

[Oliv996]

I see what you mean Danny. I will correct this point :lol:

Fantastic work as always Olivier!!! :woot:

You should ask Jimmy to make you your's own blog here on oOple! I'd love to know "where you're at" at all times! :thumbsup:

I've got tons of cars myself, but still find the handling of the XX4 unbeatable! But the belts are a bit narrow for astro and brushless...

Would it be possible to do a mod with wider belts???

[Oliv996]

Here is the Manutech Racing (http://www.manutech.info/rcracinghome/racingproducts.html) LiPo weight balancer. It's the model design for AE TC5 but once cut it fits perfect in the XX4 ;)

It has been machined a little to have 80g extra weight (40g on each side). The original part weights around 120g.

A socket head M3 screw. I reduced head diameter so that it fit the ball bearing.

I drilled a hole on the top of the part so that 1.5mm pin goes in:

I saw that you fitted the Lesro one-way but how did you center the pulley on the one-way?:woot:
I cannot seem to get it centered correctly:(
Thanks:thumbsup:

I have a few questions
what is a lesro pulley?
is that a pengiun front shock brace, how is the turnbuckle mounted at the bottom?
do you have your clickers locked? what belts do you use?
thanks

[B44&501xRacerEX]

Oliver's car is the prettiest car I have ever seen.
I have cleaned and scrubbed my XX-4 it does look good so far,
but the only way to get mine to look as good as his is buy new parts.:thumbsup:

[Danny McGee]

Just out of interest. How do you plan to run the lipo's forward? Or is that a simple answer and you wont be? :)

[lynx75]

Wow, it's a superb car, amazing.

Where did you find carbon battey holder?

Thanks.

[91notch5.0]

nice job on the bellcrank! i ca mine on and use uncure to get it off. I just tried lcds's on the front and it add LOTS of steering. Also, i run lipos with ONLY velcro!

Hi,

The front shock brace is home made inspired by Penguin model. The brace is mounted with long ballstud and secured with locknut.
I set the clicker free as I run the front oneway and green belts all the way.

[Oliv996]

Just out of interest. How do you plan to run the lipo's forward? Or is that a simple answer and you wont be? :)

Hi Danny,

I know it's out of interest for you :lol:

So yes, I don't plan to run lipo's forward but if I would, I will play with LiPo balancer weight instead of change LiPo location. What do you think about a carbon fiber lipo balancer under the left saddle and put an extra brass weight just in front of the motor ?

[Oliv996]

Wow, it's a superb car, amazing.

That is one of the nicest setups I have ever seen on any car, completely stunning. Great work Olivier; I wish I had half of your skills.:thumbsup:

[B44&501xRacerEX]

Mine is pretty much a mixture from the other 2 cars I have.
I have cut scrap carbon fiber left over from my 501 and B44.
To put on those shock towers.
I plan on buying a new body as well, and have a painter paint it for me.

[Fiddybux]

Absolutely beautiful work...really very impressive.

The only thing I would recommend is a brace for the rear shock tower camber link arms...something like this from the E-Speed parts range.

[ashleyb4]

Why its totally pointless that part was puredesigned for the x5 as you have to remove material from the shock tower.

Chill! It's just an opinion.

I used to break them when I ran a standard XX4 - I've always had one fitted and it helped me.

Agreed! - Why chance it going Ash? When for the sake of nockin' one up out of a spare peice of Carbon Fibre or buying one to make it totally safe!

Looks bomb proof already but with that extra part it will be totally 'Kitted out!'

[ashleyb4]

Ive snapped a losi titanium ball stud in a xx4 shock tower. The chances are the ball stud will snap, the hub will brake or ball cup will strip and the turnbuckle come out before you brake the tower.

about the steering mod, how long is the 3M screw used?

Now you're addicted to DP490 :lol:

SHY, I would be please to see your work done on pics :drool:

[SHY]

The stuff is great! Binds well and easy to dremel afterwards!

But it does indeed run a little before dry... do you use heat to make it dry quicker?

What's that heatsink on the motor you've used? LRP?

Yes SHY, it takes a while to dry as deep as enough to dremelize. In fact, this delay becomes longer with old tubes of DP490... That's the deal with this kind of epoxy glue, we have to cope with it :cry:

The motor heatsink is the Trinity aftermarket option part for XX4. Very hard to find one, even on eBay :(

[SHY]

Part no?

[Rocking Donkey]

I remember seeing the motor heatsinks on the DMS website not too long ago, although I think they were red. Might be worth getting in touch with them?

[Oliv996]

I think it's TK1100 :rolleyes:

thanks, ill be working on that mod this weekend.

May i ask how you got the front shock tower brace to be flush with the tower? how did you mount it at the bottom?

[lynx75]

Hi Oliv996,

what Tekin brushless motor is installed on your wonderful XX4 please?

Is Tekin motor a 6.5T?

It is an outdrive saver, a little sleeve that fits over the plastic outdrive to strengthen it. Some people just use steel outdrives.

[purplenut]

Awsome work there you really did some work on this specially the esc tidy.
Now wish i not sold mine.:(
Great work tho:thumbsup:

[Legacy555]

Can anyone shed any light on how to weight up the XX4? I bought the manutech weights and they are far too heavy and in the wrong place altoghether. You can happily run lipos in the XX4 with 30-40g of total additional weight around the cells - 120g is far too much. So far Ive put 40g inside the front belt tunnel, 30g beside the spur gear spy hole, and 10g under the clicker spy hole, and 20g under each lipo. It's getting there, but still not quiet right. Any advice from anyone?

[SHY]

I simply prefer no weights added at all, no matter the surface. I just put very little lead on the outside of the tunnel / inside of the saddle pack LiPos to get it legal.

Low weight also saves the belts, which are very narrow for todays performance (snap easily).

I do this with the std. Worlds setup (see manual). Plus Ellis' steering mod. And front diff, no one-way.

It drives amazingly! :thumbsup:

Ok, I've been experimenting ;), and this weight setup doesn't allow you to get the most from the car. It's only about as quick as the dialled 2wd cars. The car pivots about the rear end too much.

So I've added 110 grams between the front belt housing, around the bellcranks and either side of the slipper shaft. It's much better - about 5% quicker - but still not fully there.

I'm going to copy Danny McGee's weighting now - as below - basically relocating the esc behind one of the lipo cells. hoping for an improvement..... :D

http://www.oople.com/rc/photos/2009national-talywain/4wd/bigimages/OOP_4081.jpg

[Oliv996]

I didn't run so much my XX4 but I already break a chassis on the front end, on one of the two "ears" which hold thread inserts for mounting the front bulkhead :(

I don't know if someone had already done the mod I made, but here it is described below.

So on a new chassis I decided to modify it by drilling two additional hole in order to insert longer front arm hinge pin in the bulkhead.

First mod, I used two old 1.2" rear shock shafts where I cut the threaded tips. On the following picture, one is cut and one is still uncut)
http://img708.imageshack.us/img708/6189/img0268gf.jpg

Then with an 1/8" drill bit through the bulkhead I drilled the chassis:
http://img849.imageshack.us/img849/624/img0270gc.jpg

Here are some pictures with long hinge pins in place:
http://img688.imageshack.us/img688/4830/img0280kl.jpg
http://img29.imageshack.us/img29/6779/img0276ecr.jpg

Hope now it will prevent any ear breakage. I suppose I will break more front arms due to rigidify the the bulkhead but arms are less expensive than chassis and much more easy to replace than chassis....

Just my two cents

[Naushad]

I think you'll eventually crack the chassis with the hole you've made.

[SHY]

Heard today that the XXX4 is now finally discontinued. Maybe now the wait for an updated XX4 is soon over!!! :thumbsup:
