JCR SSP 2.0 Pro Combat Robot Kit – Transmitter Bundle
SSP Pro — Faster, Better, Brushless
The SSP 2.0 Pro brushless beetleweight combat robot kit is designed by Seth Schaffer of Just ‘Cuz Robotics — the team known for competing alongside Bloodsport on BattleBots. Competition-proven and trophy-winning, the SSP Pro is a no-spinning-weapon control bot — no test box required. Built on a single-piece UHMW billet chassis with brushless drive, a 42kg-cm servo, and the JCR Motherboard, it’s ready to assemble and battle. Full CAD files are included so you can mod, print, and make it your own.
This bundle includes Seth’s recommended starter radio, the FlySky FS-i6. It’s ideal for builders who already have a LiPo charger but need a transmitter. If you need both a transmitter and charger, choose the SSP 2.0 Pro Transmitter & Charger Bundle.

What it is / Who it’s for
The SSP 2.0 Pro brushless beetleweight combat robot kit is the brushless edition of the popular beetleweight lifter kit from Just ‘Cuz Robotics. It’s designed for builders who want a proven, trophy-winning beetleweight platform with modern brushless drive, clean wiring, and straightforward assembly. As a control bot/lifter with no spinning weapon, no test box is required — you can drive and test anywhere.
How it works
Blitz Lite brushless drive motors paired with JCR-RC AM32 35A ESCs handle drive on a 4S power system, giving stronger acceleration and higher efficiency than brushed drive. A quick 42kg-cm brushless servo controls the lifting arm. The custom JCR Motherboard handles power distribution, switch, LED, and dual voltage BECs in one small package — keeping the build clean and troubleshooting simple.
What’s included / What you’ll need
The kit ships as a single unit with everything needed to build the robot: UHMW billet chassis, all drive and servo electronics, three front-end configurations (barbed forks, claw forks, and wedge), a 4S LiPo battery, FS2A receiver, and the JCR Motherboard. This bundle also includes a FlySky FS-i6 transmitter — Seth’s recommended starter radio, compatible with both SSP Standard and Pro. You’ll still need a LiPo charger, soldering equipment, and basic tools. Prefer a pistol-grip style radio? The Radiomaster MT12 is a popular alternative — sold separately.
| Component | Details | Included |
|---|---|---|
| SSP 2.0 Pro Combat Robot Kit | Complete Pro kit with chassis, brushless electronics, front-ends, 4S battery, and receiver | ✅ |
| FlySky FS-i6 Transmitter | Seth’s recommended starter radio — drive mixing must be programmed on the radio for Pro kit | ✅ |
| LiPo Charger | Not included — needed to charge your battery | ❌ |
Need a spare battery? The Pro kit uses a 4S system — our Tattu 450mAh 4S LiPo is a good event spare to stock.
Modularity and upgrades
The SSP 2.0 was redesigned from the ground up for modularity. The vertical spinner module attaches via a dedicated cutout in the chassis base. CAD files for all components are available under Product Documents — print your own replacement parts, design custom attachments, or modify the chassis to suit your build. Want to see what others have done? Check out the SSP mod gallery.
All SSP 2.0 CAD files are also available directly on GrabCAD — STEP models for all configs, attachments, and addons.
Competition record
SSP kits have placed in tournaments across the US and internationally. Watch the SSP 2.0 go up against NHRL’s Rank 1 beetleweight Mako: SSP vs Mako at NHRL. There’s also an active SSP Owners Group on Facebook for build help and community support.
Sold as a bundle — one SSP 2.0 Pro kit and one FlySky FS-i6 transmitter per order.
Safety Warning:
Weaponized robots are not toys. Spinning weapons generate extreme kinetic energy—comparable to a power tool. Always use caution, engage a weapon lock, and test kinetic energy only within a secure arena or test box. Note: the SSP Pro base kit has no spinning weapon and does not require a test box — however, if you add the optional vertical spinner module, all spinner safety rules apply.

"2.0 with the Blitz brushless motors is crazy powerful. It's zippy and has all the pushing power you need."
Notes:
- Small hardware and 3D printed parts are not listed in this maintenance table
- The SSP UHMW chassis and Titanium lids are no longer offered in SSP 1.0 versions
- G10 lids for SSP 1.0 are only available for a limited time. When they are gone, they are gone
- Select Dragon motors for SSP Standard; select Blitz Lite motors for SSP Pro
- Select the 74T 222mm belt (4mm wide)
This robot requires a transmitter and receiver-compatible charger to operate. If you don't already have these, we suggest the FS-i6 and C6D charger, or pick up one of our bundles. This bundle includes the FlySky FS-i6 transmitter. For transmitter documentation and setup, see the FS-i6 product page.

Frequently Asked Questions
What's included in this bundle?
This bundle includes the complete SSP 2.0 Pro kit plus a FlySky FS-i6 transmitter. The kit itself includes everything needed to build the robot: UHMW billet chassis, Blitz Lite brushless drive motors, JCR-RC AM32 35A ESCs, 42kg-cm brushless servo, JCR Motherboard, FS2A receiver, 4S LiPo battery, and three front-end configurations (barbed forks, claw forks, and wedge). Full CAD files for all components are included via Product Documents.
What else do I need to run it?
You'll need a LiPo charger, soldering equipment, and basic tools (4mm hex key, T15 Torx driver, needle nose pliers). Blue Loctite 242 or 243 is strongly recommended. The full list of required tools and equipment is in the assembly guide under Product Documents.
Who can build this kit?
The SSP 2.0 Pro is designed for builders ages 10 and up. Soldering is required — adult supervision is recommended for builders under 13. Everything else can be assembled by anyone who can hold a screwdriver. Even 10 and 11-year-olds have competed successfully with SSP kits at events around the world.
What makes SSP Pro different from SSP Standard?
The Pro upgrades the drivetrain to Blitz Lite brushless motors, JCR-RC AM32 35A ESCs, a 42kg-cm brushless servo, and a 4S power system — delivering more speed, power, and responsiveness. The chassis and overall layout are the same. See the full comparison on the SSP 2.0 Pro page.
Which transmitter should I use?
The Pro kit uses two separate brushless ESCs with no built-in drive mixing — so the transmitter must have drive mixing programmed. This bundle includes the FS-i6 — Seth's recommended starter radio. Seth's assembly guide (under Product Documents) walks you through programming drive mixing step by step. Prefer pistol-grip? The Radiomaster MT12 is available separately.
Summary: Pro kit — you must program drive mixing on the TX.
How long does shipping take?
Typical lead time is 2–7 days after purchase.
As seen on TV?
Yep. The SSP kit was featured on the Today Show. Watch the segment here.
