Plexiglass fins are used on some competition model rockets (including scale models), as are waferglass fins (see: http://www.ninfinger.org/rockets/ca...4apogeecat.html ). Stuart Lodge mentioned plexiglass fins in his "The Model Rocketry Handbook." They--and waferglass fins--can be made very thin and lightweight, and for scale models, plexiglass fins are easier to sand beveled, wedge cross-section (or circular-arc cross-section) leading edges into (and trailing edges too, if the particular design calls for them). If you find more complete IRIS-T scale data, a second model could have more detailed-shaped fins and wings made of plexiglass. |
