Rule-based compatibility, explained
Shops shouldn't have to guess at the counter. We make compatibility explicit.
Phase 1 focus: Battery ↔ ESC compatibility (including connector mismatches).
The current problem
Right now, most shops verify battery ↔ ESC compatibility by eyeballing specs or relying on experience.
RC Fitment turns those assumptions into explicit, deterministic checks.
Explicit checks
- Battery voltage must be within the ESC's supported range (ex: 6S battery + 3S max ESC → Incompatible)
- Connector types must match, or the system flags "Adapter required"
- Estimated current draw must not exceed ESC rating
- If any rule fails, you get an incompatibility warning with the reason
Simple process
What you'll see:
Deterministic rules — not AI guessing. Every compatibility check follows explicit, verifiable logic.
If you run an RC shop, this probably sounds familiar
Most RC shops lose time and margin here — they just don't see it until returns pile up.
Customers order the wrong battery online — you eat the return shipping and restocking
A customer returns a battery or ESC after it "didn't work" — and now you're eating the cost
Compatibility depends on one experienced employee being present
New staff guess — or over-explain — at the counter
You rely on memory, charts, or brand PDFs mid-sale
Wrong part sales don't just cost money — they cost trust.
RC Fitment isn't a parts search tool.
It's a compatibility engine.
RC Fitment is designed around how RC shops actually sell.
Electrical compatibility (voltage, current, connectors)
Protocol compatibility (radio → receiver)
Physical constraints where applicable
Known incompatibilities before checkout
Clear answers. No guesswork.

Why shops want this
Fewer returns
Problems are caught before parts leave the store.
Faster sales
No digging through charts or second-guessing.
Less reliance on one 'RC guy' being on shift
New employees sell with the confidence of experienced staff.
Higher customer confidence
You're verifying — not guessing.
Why this exists
Most compatibility today relies on memory, brand charts, online guesses, or AI answers that can't explain why.
RC Fitment is built by mapping real RC standards and constraints — not scraping product descriptions.
