Re: Registration Statement on Form S-1 (SEC File No. 333-270519)

Ladies and Gentlemen:

We have acted as counsel to Unusual Machines, Inc., a Puerto Rico corporation (the “Company”), in connection with its filing on the date hereof with the Securities and Exchange Commission (the “Commission”) of a registration statement on Form S-1 (the “Registration Statement”) under the Securities Act of 1933, as amended (the “Act”), relating to the proposed public offering of: (i) 1,500,000 shares of common stock of the Company, par value $0.001 per share (the “Shares”), (ii) up to 225,000 additional Shares ( the “Over-Allotment Securities”) for which the underwriters have been granted an over-allotment option; and (iii) an underwriter’s warrant (the “Underwriter’s Warrant”) to acquire up to 75,000 shares of Common Stock granted to Maxim Group LLC, the representative of the underwriters.

The Shares will be sold by the Company pursuant to an underwriting agreement to be entered into by and between the Company and Maxim Group LLC (the “Underwriting Agreement”).

This opinion is being furnished in connection with the requirements of Item 601(b)(5) of Regulation S-K under the Act, and no opinion is expressed herein as to any matter pertaining to the contents of the Registration Statement or related prospectus or prospectus supplement (collectively, the “Prospectus”), other than as expressly stated herein with respect to the issuance of the Shares.

As such counsel, we have examined the Registration Statement and originals, or copies certified or otherwise identified to our satisfaction of the Company’s Articles of Incorporation, as amended, and Bylaws and such other documents, records and instruments as we have deemed appropriate for purposes of the opinion set forth herein. With your consent, we have relied upon certificates and other assurances of officers of the Company and others as to factual matters material to this opinion without having independently verified such factual matters. We are opining herein as to the laws of Puerto Rico and we express no opinion with respect to any other laws. In addition, the foregoing opinions are qualified to the extent that (a) enforceability may be limited by and be subject to general principles of equity, regardless of whether such enforceability is considered in a proceeding in equity or at law (including, without limitation, concepts of notice and materiality), and by bankruptcy, insolvency, reorganization, moratorium and other similar laws affecting creditors’ and debtors’ rights generally (including, without limitation, any state or federal law in respect of fraudulent transfers); and (b) no opinion is expressed herein as to compliance with or the effect of federal or state securities or blue sky laws.
