Effective July 23, 2026.
Part 107 Ace is operated by Swell & Stack Co. LLC, doing business as Swell & Stack Co., a Wyoming limited liability company ("we," "us"), 30 N Gould St, Ste R, Sheridan, WY 82801, USA. By using the site or buying the upgrade you agree to these terms.
Part 107 Ace is a study tool for the FAA Part 107 (Remote Pilot) knowledge test. A set of practice questions is free. For a one-time $9.99 USD payment you unlock lifetime access on this site to the full question bank, unlimited mock exams, and weak-area drilling. "Lifetime" means for as long as we operate the service.
Part 107 Ace is an independent study aid. It is not affiliated with, endorsed by, or sponsored by the FAA or any government body. We don't guarantee a passing score — the real exam is administered by the FAA/PSI and its content can change. Use this alongside the official FAA study materials.
Because a substantial set of practice questions is free to try before you buy, you can fully evaluate the tool at no cost, so purchases are generally considered final once the full bank is unlocked.
That said, we want you to be satisfied: if you're unhappy with your purchase for any reason, email [email protected] within 14 days of buying and we'll refund your $9.99 in full — no complicated hoops. If a technical problem or duplicate/erroneous charge occurred, contact us any time and we'll fix it. Nothing here limits any refund or consumer right you have under applicable law.
Payment is processed by Stripe. We never see or store your full card details. The charge is a single one-time payment — this is not a subscription and nothing recurs.
The content is for your personal exam preparation. Don't scrape, resell, redistribute, or republish the question bank. Don't attempt to bypass the paywall or disrupt the service.
The service is provided "as is." To the fullest extent permitted by law, our total liability for any claim relating to Part 107 Ace is limited to the amount you paid us (at most $9.99), and we're not liable for indirect or consequential damages, including exam outcomes.
These terms are governed by the laws of the State of Wyoming, USA, without regard to conflict-of-law principles, and disputes will be handled in the courts located in Wyoming, unless applicable consumer-protection law requires otherwise.
We may update these terms; the current version always lives here with its effective date.
