Re: Registration Statement on Form S-1

Ladies and Gentlemen:

This opinion is furnished to you in connection with a Registration Statement on Form S-1 (the “Registration Statement”) being filed by UAS Drone Corp., a Nevada corporation (the “Company”), with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended (the “Securities Act”), for the registration of (I) 63,856 shares of the Company’s common stock, par value $0.0001 per share (the “Common Stock”) to be issued to certain stockholders of Duke Robotics, Inc., a majority-owned subsidiary of the registrant, upon the consummation of a short-form merger agreement (the “Primary Offering Shares”), and (II) an aggregate of 18,200,592 shares of Company’s Common Stock to be sold, from time to time, by the selling stockholders identified in the Company’s Registration Statement under the heading “Selling Stockholders,” which consist of (i) 14,550,859 shares of Common Stock held by certain selling stockholders (the “Selling Stockholder Shares”), (ii) 2,580,214 shares of Company’s Common Stock (the “CLA Shares”) issuable upon conversion of certain convertible loan agreements (the “Convertible Loan Agreements”), and (iii) 1,069,519 shares of Company’s Common Stock (the “Debenture Shares”) issuable upon conversion of convertible debentures (the “Convertible Debentures”).

We are acting as counsel for Company in connection with the Registration Statement. We have examined signed copies of the Registration Statement, the Convertible Loan Agreements and the Convertible Debentures, and have also examined and relied upon minutes of meetings of the Board of Directors of the Company as provided to us by the Company, the Articles of Incorporation and By-Laws of the Company, each as restated and/or amended to date (collectively the “Charter Documents”), and such other documents as we have deemed necessary for purposes of rendering the opinions hereinafter set forth.

In our examination of the foregoing documents, we have assumed the genuineness of all signatures, the authenticity of all documents submitted to us as originals, the conformity to original documents of all documents submitted to us as copies, the authenticity of the originals of such latter documents and the legal competence of all signatories to such documents. Other than our examination of the documents indicated above, we have made no other examination in connection with this opinion.

The opinions rendered herein are limited to the Nevada Revised State Statutes and the federal laws of the United States. For purposes of our opinion, we have examined an official compilation of "Title 7 - Business Associations; Securities; Commodities, Chapter - 78 - Private Corporations" of the Nevada Revised Statutes. Such examination was limited to the provisions of such statute only, and did not include any annotations or commentary related thereto. We do not purport to be experts on the laws of the State of Nevada and our opinion is based upon such limited experience. We express no opinion herein concerning the federal laws of the United States of America or any state securities or blue sky laws.

(2) The Selling Stockholder Shares are duly authorized, validly issued, fully paid and non-assessable securities of the Company;

(3) When the CLA Shares are issued and sold as contemplated by the terms of the Convertible Loan Agreements and as contemplated by the Registration Statement, the CLA Shares will be validly issued, fully paid and nonassessable; and

(4) When the Debenture Shares are issued and sold as contemplated by the terms of the Convertible Debentures and as contemplated by the Registration Statement, the Debenture Shares will be validly issued, fully paid and nonassessable.

We hereby consent to the filing of this opinion as Exhibit 5.1 to the Registration Statement and to the reference to this firm under the caption “Legal Matters” in the Registration Statement.  In giving such consent, we do not admit that we are in the category of persons whose consent is required under Section 7 of the Securities Act or the rules and regulations of the Commission.
