i have offered to repair the chassis on my friends T9, i think the motor housing can be done but the main problem is the crumbling chassis extention that the bogie fits to. It has all the tensile strength
of a corn flake ! - when i was trying to find out how it was located it fell apart in my hand. The basic design was so flawed it never had a chance - seems the chassis has to rely on the body to hold it all
together ! A scratchbuilt plastic front frame extension may be the answer. As many of you will be trying superglue for this repair it helps with porous surfaces to dampen the areas to be glued.
