settling suspension

I'v had my Tiger running for a couple of weeks now and have spent some time adjusting the track tension and filing the edges of the drive sprockets to prevent throwing a track whilst driving over some faily challenging terrain (300 tons of spoil from ground work being done around my house).
She is now running really well and performs very impressively as long as, just like the real thing, its carefully driven over tricky bits with minumum neutral turns on slopes etc.

However the suspension has settled bringing the tank hull lower to the ground and sometimes if driving over a narrow object, branch etc, the tracks will ground into the underside of the pannier with a realistic but disturbing grinding noise. Over undulating ground its fine. So, does anyone know what the distance should be from the top of a central roadwheel to the underside of the pannier when the Tiger is on the ground? If I discover the suspension needs to adjusted has anyone found a way of doing this in situ without removing all the roadwheels and the hundreds of ****** bolts!

Hello Steve

The suspension must be set up at 35 degrees.The Torsion bars must have a Flat on them for the Grub screw to bite into.This is critical as the Axels will just rotate on the torsion bars therfor collapsing the suspension.If this has happened you have to take all the wheels off and reset the torsion bars to set them up again. There is no short cut to this proceedure.Please give me a ring if more help required.

yes I did all that, I just wonderd what the acceptable measurement was between top of road wheel and underside of pannier when the tank is loaded.

Hello Steve

Ive just measured the late Tiger and Mine is 90mm from pannier to top of the wheel. if the angle has been set up.

Steve,

I set mine at 35 degrees and have run the model a lot. Mine has also settled so that the tracks ground against the underside of the panier, and the tank also has a slight tail down attitde. This is due to the weight of the batteries. I am not sure what the actual distance should be between say the wheel axles and the underside of the panier but mine could certainly do with another 10mm clearannce really.

Rather than go for all the torsion bars to re-set them I've ben thinking of putting an extra spring on the rearmost road wheels becaus the tank runs very well over objects and looks good sostiffening the suspension to make it run higher may not be the way to go. I was thinking making an arm to go over the axle where the torsion bar is clamped and then mounting an additional 1/5th scale car suspension unit which is adjustable.

Hi Allan

were you thinking of adding a sprung arm to the torsion bar or fiittng it underneath the pannier and atop the axle arm?

Steve,

I was thinking of adding it to the torsion bar end of the suspension with an arm sticking up vertically and the additional suspension unit mounted horrizontal on the inside of the lower hull
