DEX210 chassis ????

[slippy]

Hi all. I have a DEX210 RTR and am interested in changing the chassis to alloy as when I had RM config it was fine but since changing to MM adding weight losing bracing and changing things to suit me the chassis now flex,s between the battery and the motor to a level I,m not happy with. Now the part no. for the chassis in the RTR manual according to Durango,s site does not exist.
So.

Which chassis does my rtr have ?

Which alloy chassis would be a direct replacement ?

Do you know of a better choice ?

Would changing to alloy be beneficial ?

Cheers.

Dave.
