New B4.1?
 

Anyone seen the new B4.1 and also T4.1 models? Much better than a B4?

Cheers!

Beanie

care to post a link?

Isn't that just to do with the new 2.4 radio etc as that's still not a FT kit etc.

looks like they have changed the chaasis to the same facilities as the sc10, and 2.4ghz radio.

Thumbscrews on the batttery strap too....look a better idea but perhaps less sturdy than the older screws? Toying with getting a roller B4, from what you see, worth geting the 4.1 or not frankly that much different?

The B4 looks to have the new shock towers too.

This is the biggest difference......:o :thumbsup:

Apart from the diff & a bit of anodising, it dosnt look like much has changed? Unless I am missing something?

Pretty good for a RTR though...

the B4 has been SC10-a-fied!!

Hmm...wonder if that could be shoehorned into a BJ4 or B44...

Not a hope in hell of getting that into a 4wd. Had it in my hands and gave it a bit of thought but would be a total nightmare and probably not work.

Looks like it has a new body too. Judging by the fotos it also has the new shock towers on it too...

Never mind that does it go into an X6 :confused:

Hmm....what's better in the B4, ball diff or gear diff? if Gear diff, do you adjust by using different viscosity oils like in my 1/8?

I usually run 1/8 nitro/leccy (Losi 8T/e) but am looking at getting a 1/10 buggy for some indoor fun during the winter months...

looks like a new shell aswell

Anyone know if the B4.1 shock towers have different geometry? US drivers seem to be running a '4th hole' on the rear shock tower on their FT's, running lipo with very little weight added. Would be interested to know if the shocks are at more of an angle with these towers.

AFAIK the front tower is the same but thicker and made of different plastic.
The rear has the 4th hole and the outer hole on the current tower has been taken off.

Thanks Richard, I'll have to get myself one of the rear towers then as I've been messing around running with lipo and no added mass with some self drilled 4th holes - not the most accurate drilling in the world though!

Has anyone else tried running lipo with no added mass and using softer springs and/or the 4th hole?

Did I see something about the gear diff being adjustable? How does this work and is it any good? There's no oil in it, right?

Sparrow.. as you have had a good look at it, any idea if it will fit an x6 ??

b44 has a crown and pinion gear, look at the pic of the diff!!


the sc10 does not fit in the b4 without using the sc10 gear box, so id say no!

To fit a AE gear diff in a B4 or X6 you need ;

SC10 gear diff
SC10 gear case
SC10 Metric diff bearings
SC10 T plate (gear box mount)

Them parts wont fit an X6 Mark....

Has anyone yet tried the gear diff vs ball diff and measured lap times?

My friends has few Durangos at the moment and they work great indoors and outdoors aswell.

Sorry for the late reply. I think the transmission case on the X6 is too narrow to take the diff. additionally, the diff bearings on the gear diff are metric, so won't fit properly...

An Xfactory transmission case that ate the gear diff would be cool though :)

Of course they wont! what was I thinking, I must have had a few beers when I wrote that, but all those bits will work to get a gear diff in a B4!

Some will fit a B4 but not all though..... :p

I know in 4wd gear diffs are just as good a ball as i tested in the early 90's and prefered the gear mainly down to the torque i could get out of a corner using gear. I tried in 2wd as well and was not as good with gear so went back to the better suited ball which gave more control. I hope this info helps you out a bit
