Advertise where drive decisions happen

Users on eCalc are actively choosing components — not browsing casually. Banner ads put your brand in that moment.

• Motors, ESCs, props, batteries, UAV kits and drive accessories
• Brands selling into electric RC airplane, multicopter, helicopter, jet and UAV

Prefer a branded calculator instead of (or beside) ads? See White Label below.

Your budget reaches a strong, focused audience in model flying and UAV. Slots are limited (max. 25). Ads rotate every 20 seconds, so your banner is seen about 1,000 times per day.

Responsive placements (we scale to height; keep aspect ratio at the sizes below):

• 970 x 90 — displays wider than 1024 px
• 728 x 90 — 768...1024 px
• 320 x 100 — below 768 px (e.g. smartphones)

Link to your homepage or a product page. On request we provide impression statistics.

No extra fees. Secure PayPal payment in advance. You may stop before the end of the booked period.

Send banners for hosting on our server, or host them yourself and send us the URL — self-hosted creatives update immediately when you change the file.

Accepted formats: .png (preferred), .jpg, .gif. Exact pixel match is not required if the width/height ratio is maintained or smaller than the slots above.
