Hello all, Folks, regarding the Doyusha Dc-8-61 in 1/200 scale, I would like to convert this bad boy into a series 51, here's the dilemma, how many centimeters or (milimiters) should I cut forward and aft in order to shortened the body. Suggestions.......... Regards, Cesar MIA |

I calculated 3.1cm (1.2 in.) forward of the wing and 2.5cm (1.0 in.) aft the wing. Additionally, the Doyusha wing is for a -62/3 and you will need 4.6mm (.18 in.) removed from both wingtips.

Doyashas 1/200 DC-8 is a -61.The 1/100 scale kit is a-62.No change is needed to the wing. Sparky |

Based on Douglas tech manual data, scaled to 1/200: 30.5 mm fwd 25.4 mm aft @FLYHY is correct

Jennings' data correlates with mine - to within a fraction of a millimeter.  Scott. YSCB/CBR |

Greetings! Why are you bothering with measurements? That kit has windows molded in, does it not? The DC-8 window frames are 40 inches and the -61/-63 were stretched 440 inches (36ft, 8in), the -62 was stretched 80 inches, blah, blah, blah........ Simply remove 6 windows forward and 5 behind the wing and the result is a short DC-8 fuselage. Whether the final measurement is correct or not is immaterial, because that is how Douglas stretched the real one, so if the kit does not come out at the correct length, it (the kit) was wrong to begin with. Period. But, at least you'll have the correct number of windows. Regards, Jeff Jarvis |

Don't assume that all aircraft have equidistant spacing on all windows - they don't by a long shot. I can't recall about the DC-8 off hand, and I'm not where I have access to my machine with the information on it. I know the 737 family has **widely** varying frame spacing all down the length of the fuselage. I use dimensions because they come out of the manufacturer's manuals, and they're accurate. |

Greetings! I didn't assume that all aircraft have equidistant spacing because we are talking about the DC-8 specifically, and it does. Naturally, some aircraft, such as the United -61 airplanes, may have an extra window near the rear, but the fuselage frame spacing for each window was 40 inches and that holds true for the length of the constant diameter fuselage section. Measuring on the Doyusha -61 kit is not necessary because it has molded window openings. The easiest way to unstretch his -61 to make a -50 is to remove 6 windows forward and 5 aft of the wing, and if the length is not correct it also was not correct to start with and is not correctable by using measurements for cutting anyway. I suspect the tail cone on that kit as a reason for any length disparities since it looks all wrong. Regards, Jeff Jarvis |
