longer xxx4

[branstonpickle]

does any one have any idear how to make the losi xxx4 longer and less twitchy as mine always wants to keep swapping ends is there anything u can dremel to make it better any pics would help thx

[Gnarly Old Dog]

I'm currently looking at doing just that to my XXX4 also.
What I think should be possible is to push the front wishbones further forward to straighten the driveshafts. You'll need longer hinge pins and you'll need to space the front hinge pin brace further forward but I reckon it can be done.

I also tend to run mine with the rear hubs spaced as far back as possible but stretching the front seems to be the easiest option I can think of.

I think you'll need to be ingenious with regard to fixing the front bumper because you'll lose the two screws that bolt through from the front gearbox housing but I'm sure that can be overcome.

Sorry but I've not got any pix yet - but I have got myself a set of the longest Losi Ti hinge pins I could find (LOSA6094) which are 2.125inch long as opposed to the standard car's 1.90inch front pins - so I should be able to achieve about 5mm I reckon.

Stering ackermann will change though which could create further problems to solve.

Iv filed the back wish bones and added 5 mm to each was going to file the front pivot block down and space the wish bone forward with out changing the front to much

[Mark Boos]

Try to switch the rear wishbones from left to right and vice versa and mount the shocks in front of them. It shortens the wheelbase and transfers more weight to the rear. I also run a front swaybar if there is to much grip.
Thought about dremeling the front suspensionholder, too, to lengthen the wheelbase.

dont drive around in an antique and you wont have these "little" issues

[crewie]

Lengthening the rear will take grip away i would of thought as you would have less traction on exit. Does it swap ends going into or out of the corner?

6 of 10 in the A Final at the US Nationals were these "antiques". Worlds A-main qualifiers using "other" cars were in the B and C. Somebody has it figured out.

jamie i have two words steering lock you could just turn it down and i will put money on you have your steering curve set to either 0 or a plus figure.

stu

[branstonpickle]

it is 0 will try it longer wed if it dont work ill turn the wishbones back round

[Southwell]

I tried it, got it longer and lost all the lock on the outside wheel. Tried loads to fix it but it just didn't work properly.

I've been having a look at my XXX4 and I think if you flip the front wishbones round, put the shocks on the rear of the shock tower
and turnbuckles to the front it might just work.

Thats exactly what i did, but the lock on the outside wheel was awful.

The other issue is the chassis ground out on fast corners.
