I tried an ansmann 18 this morning and it had amazing speed when 3rd clicks in it just goes sideways. Nipped back to the shop (kings lynn models) and bought a 21, bit better for shorter runs...
I need the snow to melt so i can try it on some proper ground, also went to my local car tyre shop and got some sticky weights to try and balance the old gal. I have also tried a mod of my own for the 3rd shock set up on the rear. I used a couple of 'o'rings placed round the axle mounts and then secured them to the battery tray, a little experimental twisting of them to give some tension and hey presto the front mount sits in the middle of the slots with no banging during accel/decel.
