TheMongoose Posted November 28, 2018 Share Posted November 28, 2018 (edited) Can anyone tell me what the angle should be off vertical? I am modifying the old Hasegawa YF-18 model in 1/32 and in place of the kit vertical stabilizers I have the Avionix A tail mod that comes with their resin cockpit. Since they don’t fit in the existing slot the angle will have to be set but I cannot seem to find this piece of information so far. Thanks in advance! Chris heres a pic of the pins i made to align them and hold them in place while the epoxy sets Edited November 28, 2018 by TheMongoose Ref to resin manuf Quote Link to post Share on other sites
Dave Roof Posted November 28, 2018 Share Posted November 28, 2018 (edited) The angle is 20 degrees out from center. Do you mean Avionix? Aires doesn't make vertical tails for the F/A-18A. **Corrected my mistake** Edited December 5, 2018 by Dave Roof Quote Link to post Share on other sites
TheMongoose Posted November 28, 2018 Author Share Posted November 28, 2018 Yes, avionix, sorry guess it was late when i wrote that. Will edit it 🙂 Quote Link to post Share on other sites
Matt Walker Posted November 28, 2018 Share Posted November 28, 2018 BTW. Dave made a jig for the 48th scale Hasegawa Hornets to set their incidence correctly. If you asked him nicely, he may do one for 32nd scale! M Quote Link to post Share on other sites
TheMongoose Posted November 28, 2018 Author Share Posted November 28, 2018 I drilled and pinned mine. Here it is using my handy iphone level app lol i hate finding new uses for this stupid thing. After a double check I’ll spot glue them before using epoxy to lock them into position. Let me know if you all see anything goofy in this pic? Quote Link to post Share on other sites
TheMongoose Posted December 4, 2018 Author Share Posted December 4, 2018 Dave, does this look like I’m measuring it correctly? It seems kinda vertical so I thought i better check and make sure. Matt mentioned you made a jig for it so that also makes me wonder if I’ve got it right? Quote Link to post Share on other sites

It seems kinda vertical so I thought i better check and make sure. It does. I checked with multiple pictures and some of the better line drawings, and they all have angles of 19°, not 12°. That's not total proof (line drawings are sometimes mistaken, angles are not always preserved depending on the focal length of photographs), but they are consistent with each other. That's what I used on my F-18 models. Quote Link to post Share on other sites

That's what I used on my F-18 models. A 9 October 1981 McAir General Arrangement drawing has them angled out from vertical by 20 degrees. The tips are 11.8 feet apart and the roots are 79.5 inches apart, toed out by one degree. Measurements are to the center of the airfoil. Quote Link to post Share on other sites
TheMongoose Posted December 5, 2018 Author Share Posted December 5, 2018 Superb reference checks. Thanks gang! I will make adjustments and get these glued in shortly now. Quote Link to post Share on other sites

Yep, my fault for not checking my pubs before answering. The verticals toe out 1 degree at the leading edge and cant 20 degrees from the vertical. I believe I got the 12 degrees from that 1 and 20 using my memory (which proved to be a bad thing). My reference is A1-F18AC-GAI-000, which is the O-level General Aircraft Information Technical Manual. Quote Link to post Share on other sites
