what ever you do dont use velcros i used velcro's on my trf414m. it falls off during big hits. i thought the ta04 had the plastic holders on it????
this stuff should do the job
the tamiya one like the person who said it earlier
its thin so it wont scrape the ground. its super strong.
it good stuff but i rather have the trf come with some carbon fiber peice that comes over the battery
