This fix is valid for the buggy version such as HSP - XSTR, REDCAT - TORNADO, EXCEED - SUNRISE and other alike.
I have managed to fix the dogbone - driveshaft bending problem by putting shorter dogbones.
The dogbones i have tried are 84mm long and not 89.5mm (that size was fitted from factory)
Look the attachment for part number and size
Just remember to put either way of the dogbones pieces of rubber as (fuel tube or elastic band),
After this, absolute must fix, your buggy will jump without bending dogbones or breaking them.
Happy to share my fix
