This is going to be a slight downscale based on the Estes AMRAAM kit.
Research is often part of a build -
Here's some scattered specs I found online:
AMRAAM AIM-120
Boxed kit, #2153. Part of the Estes BETA series
Scale: 1:5
Produced 1996-2001
Original kit had stickers, not water slide decals.
Skill Level 1
Recommended Engines: B4-2, B6-2, C5-3, C6-3, C6-5
Maximum Estimated Altitude: 400 ft
My build will be a downscale from original kit BT-55 tubes to BT-50H (heavy wall tubing)
Downscale info:
Original kit tubes
#2153 AIM 120 AMRAAM 031191 BT-55 (2) 11.00" 030326 BT-20J 2.75"
Downscale tubes (2)
Two 8.20" long BT-50H tubes or single tube, 16.40" long
To downsize -
BT-55 is 1.325" diam. / BT-50H (heavy wall) is .990" diam. = Scale Factor of 1.338 or 1.34
Divide the original (two) BT-55 11" length tubes by 1.34 = (two) 8.20" long BT-50H tubes or one long BT-50H tube at 16.40"
