jonbryon Posted July 9, 2019 Share Posted July 9, 2019 Hello, I'm making two Hasegawa 1/48 AH-64s, one as a US 'D' and the other as an IDF 'Saraf'. I have a quick question: under the engine pods there are two little doors that Hasegawa mould shut (see photo below under white arrow for the open doors). Photos seem to show they are open when the aircraft is powered down and on the ground and Wingman/Isracast provide PE doors for these. Are these *always* open when unoccupied and on the ground or can I get away with not having to make my own doors for the stock US 'D' model I'm making? Thanks for your help.

ChernayaAkula Posted July 10, 2019 Share Posted July 10, 2019 (edited) They're engine cooling louvers. They open on engine shut-down and are closed when the engine's running again. SOURCE (on page 6-31) Edited July 10, 2019 by ChernayaAkula Quote Link to post Share on other sites

I'm off to scratchbuild some doors 🙂 Jon Quote Link to post Share on other sites
Cobrahistorian Posted September 9, 2019 Share Posted September 9, 2019 They close as soon as you're light on the wheels. Quote Link to post Share on other sites
Helo-Engineer Posted October 10, 2019 Share Posted October 10, 2019 They actually close based on vacuum generated by the engine shortly after start. The pistons sometimes would stick, and they need a little tap to get closed all the way. I am going to be working on one of these Hasegawa kits to build a replica of the aircraft I worked in Afghanistan. It's a great looking kit, but missing some stuff we had on ours. Plan to join up here and post progress. Quote Link to post Share on other sites
