Introductory Note:

Item 1. Security and Issuer.

This Amendment No. 3 to Schedule 13D (this “Statement”) filed by Roundball, LLC (the “Roundball”), The Three Bears Trust (the “Three Bears Trust”), Matthew V. Crawford, trustee for the Three Bears Trust, and Steven Rosen (collectively, the “Reporting Persons”) relates to the acquisition of beneficial ownership of 252,367 shares of Class A Common Stock, no par value (“Common Stock” or “Shares”) of Hickok, Inc. (the “Issuer”). This Statement amends and supplements the initial statement on Schedule 13D filed on January 9, 2012, as amended by Amendment No. 1 to Schedule 13D filed on January 9, 2013, and Amendment No. 2 to Schedule 13D filed on November 25, 2014, with respect to Shares of the Issuer.

Item 2. Identity and Background.

Item 2 of the Schedule 13D is amended and restated as follows:

This Schedule 13D is filed by the Reporting Persons (as defined below) pursuant to Rule 13d-1(k)(2) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). The Reporting Persons are:

The principal businesses of the Reporting Persons are as follows:

The principal business and office address of Roundball is 25101 Chagrin Boulevard, Suite 250, Beachwood, Ohio 44122.

The principal business address of the Three Bears Trust is: 1660 West 2^nd Street, Suite 1100, Cleveland, Ohio 44113-1448.

The principal business address of Mr. Rosen is 25101 Chagrin Boulevard, Suite 250, Beachwood, Ohio 44122.

The Reporting Persons have entered into a Joint Filing Agreement, dated November 25, 2014, a copy of which is incorporated herein by reference from Schedule 13D Amendment No. 2, Exhibit 5, filed on November 25, 2014, with the Securities and Exchange Commission.

For information required by Instruction C to Schedule 13D with respect to persons that control the voting and investment decisions of Roundball with respect to the Shares, reference is made to Schedule A annexed hereto and incorporated herein by reference. The names, principal occupations, address, and citizenship of such control persons is identified on Schedule A (persons identified on Schedule A are hereinafter referred to as “Covered Persons”).

During the last five years, no Reporting Person or Covered Person has been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors).

During the last five years, no Reporting Person or Covered Person has been a party to a civil proceeding of a judicial or administrative body of a competent jurisdiction and as a result of such proceeding was or is subject to a judgment, decree, or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws.

Item 3. Source and Amount of Funds or Other Consideration.

Item 5. Interest in Securities of the Issuer.

Item 5 is amended and restated as follows:

Roundball beneficially owns 693,285 Class A Common Shares, including 320,918 Shares held directly; 100,000 Shares which may be purchased upon the exercise of a warrant (the “Warrant”); 20,000 Class B Common Shares; and the right of Roundball to convert outstanding debt, under the Convertible Loan Agreement by and between Roundball, the Issuer, the Aplin Family Trust and, solely with respect to Section 3 thereof, Robert L. Bauman, as amended by Amendment No. 3 to the Convertible Loan Agreement (collectively, the “Convertible Loan Agreement”), into approximately 252,367 Class B Common Shares. Class B Common Shares are convertible on a non-for-one basis into Shares. (The Shares issuable pursuant to exercise or conversion of the Class B Common Stock, the Warrant and the shares subject to issuance and conversion pursuant to the Convertible Loan Agreement, as amended (subject to outstanding debt), are herein collectively the “Conversion/Exercisable Shares”). The 20,000 Class B Common Shares, which are included in the Conversion/Exercisable Shares, represent approximately 4.0% of the outstanding Class B Common Shares.

Roundball has the power to vote, to direct the vote, to dispose and to direct the disposition of 693,285 Class A Common Shares (including 372,367 Conversion/Exercisable Shares) and 20,000 Class B Common Shares. The Three Bears Trust owns 50% of Roundball, and under the terms of the operating agreement by and among the investors of Roundball, has the right to consent to major decisions by Roundball and, therefore, Mr. Crawford, as the Trustee of the Three Bears Trust, shares voting and investment control with the Manager of Roundball. The investors of Roundball also have certain rights to designate up to two managers. Under the operating agreement of Roundball, the Three Bears Trust has the right to select and designate one manager of Roundball, and Seven Investors, LLC, and LJNP Trust, jointly, initially through Steven H. Rosen, shall have the right to select and designate one manager of Roundball. Mr. Rosen has therefore been identified as having shared investment and voting control with Roundball. Currently, Frederick Widen, a Covered Person identified on Schedule A hereto, serves as the sole manager of Roundball.

Mr. Rosen also has the sole voting and investment control of 1,000 Shares, which Mr. Rosen has the right to acquire upon the exercise of 666 immediately exercisable options and 334 options exercisable on March 8, 2015. Such options were acquired individually as a result of Mr. Rosen’s service as a director of the Issuer.

The information identified in rows 1-11, and 13 of each of the cover pages for this Schedule 13D is incorporated herein by reference. Such information is based upon 1,163,349 Shares outstanding as of August 8, 2014, as reported by the Issuer on Form 10-Q for the period ended June 30, 2014, as filed with the Securities and Exchange Commission on August 14, 2014.

As previously reported, Roundball entered into a Convertible Loan Agreement on December 30, 2011, pursuant to which the issuer issued a convertible note to Roundball in the principal amount of $466,879.87. Pursuant to the Convertible Loan Agreement, Roundball has the right to cause the Issuer to borrow (and issue notes in the amount of such borrowing) up to an additional $466,879.88 (the “Roundball Option”). On December 30, 2012, Roundball entered into an Amendment No. 1 to Convertible Loan Agreement with the Issuer (the “Amendment”) pursuant to which the Issuer may cause Roundball to lend the Issuer up to $250,000 (and the Issuer will issue notes in the amount of such borrowing), but such borrowings in total with the borrowings under the Roundball Option shall not exceed $466,879.87. Pursuant to the Convertible Loan Agreement, as amended by Amendment No. 3, Roundball has the right to convert the principal amount of any notes issued into Class B Common Shares at a conversion price of $1.85 per share.

In connection with the Convertible Loan Agreement, dated December 30, 2011, Roundball and the Issuer entered into a subscription agreement, dated December 30, 2011, pursuant to which the Issuer sold 20,000 Class B Common Shares to Roundball at a price of $1.85 per share.

On December 30, 2011, Roundball converted $233,438.55 of the principal balance of the Roundball Note into 126,183 Class A Common Shares. On December 30, 2011, Roundball purchased 68,550 Class A Common Shares in a privately negotiated transaction. On August 20, 2012, Roundball converted $233,441.32 of the principal balance of the Roundball Note into approximately 126,185 Class A Common Shares. The Warrant was obtained in partial consideration for Roundball’s willingness to extend credit in connection with Amendment No. 2. The Warrant expires on December 30, 2015. The Warrant provides Roundball the right to acquire 100,000 Shares at an exercise price of $2.50 per Share.

Except as otherwise identified in this Item 5, no other person is known by the Reporting Persons to have the right to receive or the power to direct the receipt of dividends from, or the proceeds from the sale of, the Shares beneficially owned by Roundball.

The foregoing descriptions of the Convertible Loan Agreement, dated December 30, 2011, Amendment No. 1 to the Convertible Loan Agreement, dated December 30, 2012, and Amendment No. 3 to the Convertible Loan Agreement are each qualified in its entirety by reference to the copy thereof which is attached hereto as Exhibits 1, 2 and 3, respectively, and incorporated by reference from the Issuer’s filings as stated in Item 7.

Item 6. Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer.

Item 6 is amended by including the following disclosure:

Pursuant to terms of the Convertible Loan Agreement, Roundball has certain rights to nominate two director nominees for election and it has nominated Matthew V. Crawford and Steven H. Rosen, who have been elected by the shareholders. Edward Crawford, Mr. Matthew Crawford’s father, also serves as a director of the Issuer. Messrs. Rosen and Edward Crawford have served on the Issuer’s Board of Directors since 2012, and Mr. Matthew Crawford has served since February 2014.

In general, Class A Common Stock and Class B Common Stock vote as a class. However, each Class B Common Share is entitled to three votes per share, while each Share is entitled to one vote per Share. Based upon the issued and outstanding Shares and Class B Common Shares as of June 30, 2014 (1,163,349 and 474,866, respectively), the Reporting Persons attributed beneficial ownership in the Class B Common Shares represents 36.8% of any vote on which Shares and Class B Common Shares vote as a class.

On December 31, 2014, the Issuer and Roundball entered into Amendment No. 1 to Registration Rights Agreement, which modifies the previously reported Registration Rights Agreement, dated December 30, 2011, between the Issuer, Roundball, and certain investors. Amendment No.1 to the Registration Rights Agreement provides Roundball with certain demand and piggyback registration rights with respect to Class B Common Shares issuable pursuant to the terms of the Convertible Loan Agreement, the Shares, and the 20,000 Class B Common Shares. The complete text of Amendment No. 1 to the Registration Rights Agreement is attached as Exhibit 4 and incorporated by reference from the Issuer’s Form 8-K filed on January 9, 2015.

Other Matters. Other than as described above or previously reported on the initial Schedule 13D filing by Roundball, as amended, to each Reporting Person’s knowledge, there are no contracts, arrangements, understandings or relationships (legal or otherwise) among the persons named in Item 2 and between such persons and any person with respect to any securities of the Issuer, including but not limited to transfer or voting of any of the securities, finder’s fees, joint ventures, loan or option arrangements, puts or calls, guarantees of profits, division of profits or loss, or the giving or withholding of proxies.

Item 7. Material to be Filed as Exhibits.
