Intro: HPI Crawler King Knex Mods With Video!

Over the weekend I decided to modify my HPI Crawler King using Knex.
     I replaced the aluminum sway bars with Knex sway bars because mine got bent. I also made knex upper shock mounts where the shocks attach with the screws facing perpendicular to the truck instead parallel with it. This gives it an extra 2''(5cm) of wheel travel for a total of almost 8"(20cm) of wheel travel! Wow!

Enjoy the video!

    Seeing that quite a few people want to see a video I'll try to post one before the end of the week.

    Your knex crawler sounds awesome! Can't wait to see it!

    Thanks for the video, it really explains how this mod works in practice. Looks like you've achieved some good ground clearance with the K'NEX, how durable is it at speed?

    Good job using knex to fix you RC. Do knex hold as well as the aluminum or do they come apart sometimes?

    Thank you. The knex holds very well, but yes, one of the sway bars brakes every once in awhile.


    The knex is surprisingly strong. I've driven it quite a few times after I added the mods and only one of the knex sway bars has broken once.
