Thanks for that Modellor!

Cheer, Mark.

I believe Mark should already have the 10x15x4 bearings from the FC steering blocks.

I think changing the Serpent servo saver would render different Ackerman steering on the 705.

Also, why would Mark need Yokomo's front one way drive cups? He is planning to drive the front solid axle.

You guys are going to love me when I post pics of my rear diff mod...I am thinking either tonight or tomorrow night.

Thats a good point on the ackerman. It does alter the ackermann slightly. But for the better. On tests against a stock 705 with Serpent FC blocks I was able to turn about a full foot tighter radius when changing to the yokomo hubs.

The Yokomo outdrives sit further out than the Serpent ones as do the axles. So if you keep the Serpent outdrives whether for the one-way or solid axle then the drive shafts can come out at full steering lock. By using the Yokomo ones you null this problem. I should have read more carefully. But Yokomo outdrives come in packs of 4 so I can easily mix a pack if Mark was interested in having both.

Hi Modellor,

That last bit went a wee bit above my head

Are the outdrives equivalent to the serpent geardiff adaptors?

I'll try and post some picture to show the problem I've got - having trouble keeping awake for more than five minutes at a time at the moment Bloody flu!

Hi Mark.

The outdrives will fit on the same as the Serpent ones (direct bolt onto the gear diff adapters/solid axle ends). But they are also longer and the slot doesnt go as deep for the dogbone pins as the ones on the Serpent do.

The main reason for this is that the Yokomo hubs are thinner than the Serpents so the dogbone has to be kept further out. With the Serpent outdrives the dogbones can slide in too far leaving them prone to falling out. But with the Yokomo outdrives this doesnt happen.

markp27

AHA! Sounds just the job!
Is it possible to use the serpent dogbones with the Yokomo outdrives?

Sorry Arun, you'll have to wait till next Friday to post your pics (j/k)

Shoot

modellor

I never tried them for fit but I dont think so. Yokomo bones are equal sizes at both ends whereas the Serpent ones have one end larger than the other (or is that just the rear?). I'll recheck just to be sure. I am stripping my car down tonight so I will check then and let you know.

Evil pure evil!!

Interesting.

Sorry. Silly me and I misread and confused outdrives with drive cups.

markp27

I think that's the rear - I was refitting my front dogs last night and tried both ends, as I remembered that one end was bigger than the other, but both end fit ok....must be the rears that are different.

You don't have a digicam, do you?

May the force be with ya

I used a 1/8th Servo saver when I rebuilt my car last night (now to be re-built due to dog bone problems ) and now the steering arms can be mounted on the under side of the servo saver without rubbing on the belt! This is because the flange onto which the balls mount is higher up on the 1/8th servo saver as on the 1/10th part.

InitialD recommened it for a better Ackermann, but it also solves the ball fit problem, too.

InitialD

Yes, the rear doggies have one side larger at the ends than the other. The large one is suppose to go into the ball diff side and the smaller on to the hub bearings.

Ahhh, trying that lame D1 trick again on unsuspecting forumers, are ya? That's downright evil I say
