Flying with Flaps

Model Airplane News - - LET’S TALK GIANT SCALE -

When­ever ex­per­i­ment­ing with a new func­tion, al­ways climb to a safe al­ti­tude where time is avail­able to abort, and in this case, re­turn the flaps to 0 de­grees of de­flec­tion. Flaps pro­vide more lift at slower speeds, and once re­tracted, the air­craft may sink. If us­ing flaps in a con­ven­tional sense, ap­ply half and full flaps while the air­craft is trav­el­ing at a slow speed. No­tice how the air­craft’s be­hav­ior changes and how much throt­tle is re­quired to main­tain a safe air­speed above stall. With time and prac­tice, par­tial flaps can be used dur­ing take­off and while turn­ing from base to fi­nal. Full flaps should only be used once, on fi­nal ap­proach, or if you’re ex­pe­ri­enced enough to use var­i­ous throt­tle set­tings with full flaps de­ployed.

Shown here, the crow mix is ac­tive and the Ul­tra Stick is be­ing flown, with throt­tle, to the run­way for a short-field land­ing.
