TRX-4 Rear Bumper

thingiverse

I combined the hitch mount and bumper style from RCCrawler with OffScaleRC's use of a bumper mount, mixing and cutting them together to get it working properly. Since I know OffScale's bumper mount works well, I'm confident this bumper will be no issue. Initially, I printed the mount in NinjaFlex for my front bumper but wasn't satisfied because it sagged excessively due to the weight of the front bumper. The drooping caused me to get caught up frequently, although when it flexed upward, it performed amazingly. The rear bumper weighs significantly less, so you can see it doesn't sag as much. You can also observe its wide flex range in the photos provided. Alternatively, the last photo shows the bumper flipped upside down for increased clearance and reduced drag; however, you might need a drop hitch if you want to tow a trailer. I've also included my SemiFlex bumper mount, which I use for the front bumper. This mount limits downward flex but allows full upward flex, making it ideal for crawling. Update: I added the same bumper with D-Links installed. Bonus points for guessing who those legs belong to in the background!
