Thanks for posting - given me a few ideas to add to the end of the build queue.

Hello, The attached pics. outline where I have used piano wire to strengthen the chassis........as I am sure you are well aware, piano wire does have a good memory, and as such, is a much better choice than brass rod/tube.

Rear motor mount plate......(.055 wire)



The  .055 wire "L's"  give support to the front uprights, and also serve as guide rotation stops (when trimmed correctly)



.055 "L's" support the rear axle uprights, and the "U" shape supports the guide tongue area.............I solder the two chassis pieces together, but , this is not really required"



.047 rails are soldered along the bottom of the chassis plate to offer much needed longitudinal stiffness...........this is a pic. of an early build,.....I now extend the bottom rails to the front edge of the chassis plate.



A .063 pan is cut and attache to the chassis with machine screws and nylok nuts.......silicone washers are used between the chassis plate and the pan to minimize vibrations.



As modified, the handling of the car is night and day, it is much stronger in an "off", it can now handle an increase in horsepower, and it does not tip !!
