DenisV Posted September 17, 2019 Share Posted September 17, 2019 Hi all, I intend to build the Revell UH-1B/C as a PsyOp UH-1B of 118AHC equipped with side-mounted speakers. I have read most of the threads about converting Revell's kit to a B model, but one question remains unanswered : how were those speakers attached to the airframe ? I'm pretty sure they were fixed to the ship's skid, but I reckon they must have been attached to another point on the airframe. Was it the Universal Mount ? Anyone have any knowledge on the subject ?

ALEXANDRE REZENDE Posted October 14, 2019 Share Posted October 14, 2019 (edited) The USAF "F" version operated with speakers screwed into the cab ... I have a picture of the "B" version operating as "Psychological Warfare" with speakers screwed in the downhill ski ... I don't know if that helps you ...

DenisV Posted October 14, 2019 Author Share Posted October 14, 2019 Thank you, Alexandre. I was thinking, the downwash of the rotor must be so strong that a second attachment point would be necessary. By the way, this is the ship I am building : Quote Link to post Share on other sites
ALEXANDRE REZENDE Posted October 14, 2019 Share Posted October 14, 2019 (edited) Very nice! I believe there is a fixation of the top of the speakers right on the side hanger where the armaments are usually, but that's my guess ...

DenisV Posted October 15, 2019 Author Share Posted October 15, 2019 I agree with you, Alexandre. I'll attach it to the Universal Mount. Just wish I found a picture of the speaker attachment. BTW, I watched your other builds ; that's some nice scratchbuilding ! I will try to follow some of your improvements. Denis. Quote Link to post Share on other sites

Denis. Hi Denis, Welcome to Arc as a new member. No the speaker box was not mounted to the skids for good reason. Remember that skids spread on lift off and landing. You would flex the entire assembly if you hard mounted them to the skids. If they were attached to anything else you would also flex that as well and if it's the hardpoints your talking about airframe damage. Here is a better image of a 118th AHC PysOps ship. UH-1B 62-2044 'Red Tail 5' of 1st Flight Platoon from Ralph B Young's unfinished series Army Aviation in Vietnam, Volume Two 1963-1966. Clearly shows these were not skid mounted. Also, on one side only which must've been fun for the pilots trying to keep trimmed in the days long before force trim was an option. What a drag! You are correct that the fabricated speaker box was attached to the universal mount. Typically a strap was also run to a floor mount or cabin mount point in case of breakaway it would not be drawn up into the rotors or strike the tail. Quote Link to post Share on other sites
snake36bravo Posted October 15, 2019 Share Posted October 15, 2019 another angle... This is mounted in a fixed wing aircraft in this image, not a helicopter. Quote Link to post Share on other sites

snake36bravo Posted October 15, 2019 Share Posted October 15, 2019 No need for apology Alexandre. You are right on. These were mounted in fixed wing aircraft as well including the C-47 but I was worried someone would get confused by your image of the tail dragger. Quote Link to post Share on other sites

DenisV Posted July 16, 2020 Author Share Posted July 16, 2020 Reopening this subject... I stumbled upon a nice photo of a short body UH-1on the website of the 175 AHC "Outlaws". Apart from the interesting .50cal gun and the way it seems to be attached to the Huey, there is an unknown (to me) attachment to the universal mount. Could this fixture be part of the speakers installation ? (copyright vinhlongoutlaws.com) Any comments are welcome. Quote Link to post Share on other sites
