So, I've done some more mods to BluCrawler: - Converted drive motors from XL to M Motors and modified the gearing to handle the lower torque of the M's - In doing so, I've pretty much rebuilt the drive unit. - Beefed up the (4) connecting link points (to the cab) for both front and back. Sometimes when crawling they would pop out. Also beefed up the suspension link mounts. - Converted front steering to using the servo motor. Issue is that it does not provide enough throw, so I've decided to mirror the front and rear drive units. Both will steer with a servo motor each. I just finished the unit and am waiting for the new servo motor to arrive. Will post pics and a video when done.

Ahhh.. I can't wait to see how you could actually make this thing better! I've been thinking of a few mods that I want to try. 1) Seeing if a Servo Motor would work for steering (not sure if it has enough torque) 2) beefing up the front beam units that connect the black (forget their names) links to the cab unit.

After coming across PunkTacoNYC's Chilli Crawler and building one myself, it led me down a path of building my own Bluetooth controller (yes, I'm aware there are others out there :-). I've done a full write-up over at my blog. Check it out if interested.

@PunkTacoNYC this is a very cool MOC and thanks for waking me up from my Technic slumber. I built one using your instructions. Called it BluCrawler - creative name, I know... Since I only had the LEGO PF IR remote and receiver, which is not that hot, I decided to make my own Bluetooth controller. Not using SBrick or BuWizz as I wanted to customize using Blynk and write my own sketches in Arduino. Check it out if interested.
