I have been bashing for a while but when i realized that when i flip my truck the engine head kept on getting scrached. This a a small trick some guys at hpisavageforum.com told me. I hope this helps.
You will need:
An RC Car/Truck
Some Fuel tubing
Step 1: Step 1
put in the ziptie between the openings in the Engine head.
Step 2: Step 2
Slip in the fuel tubing
Step 3: Zip It and Trim It
As it says on the title Zip it and trim it and you are done !
Have fun bashing!
Thank you to the guys in HPISavageForum
