For stores/brands, creators, bugs, new rule suggestions, miscategorized products or partnerships. We don't answer individual technical "what motor should I buy" questions — that's what the configurator and chatbot are for.
Open formIf you want to integrate your catalog, sign an affiliate partnership, or appear at /en/for-brands, write to us. Typical integration: 2-3 days for Shopify, 1 week for custom spider.
If you see a product where it doesn't belong (a cable disguised as an FC, a screw kit as a motor), send us the slug and we fix it. Better: we fix the normalizer so it doesn't happen again (manual UPDATE statements get wiped on the next scrape).
If you think a compatibility rule is missing (e.g. "X mount pattern doesn't fit Y specific frame"), open the form and describe it with an example build. Already-documented rules are at /en/docs/rules.
