i have a 1/4 scale chippie with no flaps built into the wing (Came that way)
does this size of airframe need flap or should i just leave this alone?
Dave Wilshere wrote:Richard. What power set up? Its a slippery airframe with big efficient wings, I would say Flaps are needed. There is a test flight video of Pete Aston's example with an OS 40GF and although the tick over was not that slow for the test flight, even with some flap it took time to slow down. We changed the flap geometry and got just another 10mm of flap and the difference to drag is marked.
