June 2017 - Ruckus purchased RTR for my dog to chase after I broke my leg, gets boxed in attic
Dec 2021 - son sees it cleaning attic, shows interest, use it as a general basher, slowly modifying
Mar 2022 - introduced to off-road speed running group online
Oct 2022 - Ruckus went 50mph on grass, setting the new record for 2WD (any scale)
Jan 2023 - After going 51mph, a 2WD slash goes 52
Oct 2023 - Retake the record, 54mph. Later go 55 then 57
Mar 2024 - the same Slash goes 58mph
Jan 2024 - After 4 different ESCs (since 50), 8 or 9 motors, 4 battery setups, 3 chassis, 4 transmissions, and countless suspension, ballast, aero, and wheel changes we have decided 57 is the limit for this chassis. It's high center of gravity limits its high speed stability and aero. Don't worry, it's still in one piece and gets driven often, retired doesn't mean dead. I really wanted to build a maximum effort, ground up chassis with the ECX name to try and re-claim the 2WD record and be the first to break into the 60s (the fastest 1/10 scale outright is a 4WD at 68.7mph).
The AMP buggy (and a few other models) use a unique front bulkhead (where the lower control arms mount) different from the rest of the 1/10 ECX 2WD lineup. Many people have broken it (usually from aluminum front A-arms or high impact front tire crashes). Not only is this part becoming harder and harder to find a replacement for, there is no aftermarket upgrade. See highlighted/circled picture for reference.
I ended up getting a bunch of front bulkheads for other RCs for the race Ruckus build, and noticed the DR10 (Team Associated) style front bulkhead appeared pretty...

This thread got the wheels turning. I have been referring to it as an "AMP DB" because it does use ECX1017 chassis and ECX1029 top plate, but the list of other ECX brand parts is really short after that (similar to the Ruckus or any race vehicle). It never was a boxed RTR at any point, it's no longer stock wheelbase or track width and has entirely foreign front end components (Team Associated), and it never ran the chassis in stock form. I will be attempting to use a stock but modified ECX body.
The following is the list of parts someone would need not included in a RTR car to replicate this one:

Currently just waiting on the rain season to end. We have learned the hard way about being patient and not running racecars in less than ideal conditions. You learn basically nothing of value about the setup and risk wadding it all up into a scrap heap (which has happened, see the Ruckus thread). I got a chance to take it around the yard a few times and make sure nothing is catastrophically wrong. The tail was super eager to step out so I switched from the narrow MX28HPs square to the wider rears and pulled the ear plugs out of the rear diff and fully JB welded it, which improved it some. It's probably going to need some spring and shock changes to help it squat better and transfer that power to the rear. It's clearly way too powerful for our acreage which is generally around 30mph. I'm going to try and keep a wheelie bar off this if I don't have to.
