Hi,
i think it is better to make a more weight frame. So the truck drives more stable on- and offroad.
By using aluminium you have:
- problems to connect the parts
- you are unable to use the frame as eletric negative of the battery
- and it is to leight weight for good offroad driving
so I prefer brass .
If you are build onroad trucks, you can also user the original resign frame. It may the easiest way to build a small truck and it is allmost strong enough.
The book "mikromodelle" and "mikromodelle2" (availible at
www.vth.de) are only in german writing availible (sorry my english writing is to terrible for writing an english book)
-,but if you have questions or problems by reading the book I will try to answer.
best regards
Thorsten
