RB5 Diff setting

[slow coach]

Whats the best way to check the diff is set tight enough, i have done the build it torque it up by hand put in car then run the car with one side on a block for several minutes then swap sides to bed things in, but want to make sure the diff doesnt slip when i finally get round to running it (dam rain)

I normally lock up the slipper and give it a big blast of throttle on the grippiest part of the track. Set the diff as loose as you can to aid in carrying corner speed.
Reset slipper to suit.

If I feel the car is "diffing out" i will tighten the diff 1/16th turn at a time (driver through outdrive into screw head, turn wheel to adjust).

I am sure Nick "diff master" Caro will be along shortly with some more info, he's built just about every Kyosho diff in the country at one point or another!!!!

Cheers Roger will have to find somewhere with good grip to test it lol, our track is a tad muddy at the moment and im still waiting to actually run the thing.

slightly off topic but whats the opinion on the kit springs the rears dont feel like they support the car very well or perhaps the oil is to heavy if i remember i put 30 or 32.5 in there also swapped piston to the bigger holes, just doesnt feel like the car wants to come back up easily so could be overdamped or undersprung decisions decisions

also any news on the pm you sent a little while back

Slow Coach ... PM??? I'd foget my own head if it came loose.

As for springs I normally run the car with silver fronts, blue rears (maybe yellow all round on your track).

Dampers, start with 3B/35wt in the front and 3A 30wt in the rear.

Remember as both top and bottom damper bushes are plastic if you overtighten the screws they will swell and bind ... I see this a lot on peoples cars!!
