This is all part of running an old Tamiya I guess... they were never the toughest cars to begin with! My KF2s are absolute tanks in comparison.
I think by the time I'm done 're-building' my Super Astute (I used single quotes because by the time finished the only original part on the car will be the centre steering link) there'll be practically nothing left of the original apart from the rear bumper
I just hope it handles once It's all back together
