Ok for those that may grumble allow me to offer this. I am a member of several other well known rc forums in which this subject has been referenced and yes I could simply search there but for the sake of adding to knowledge base here in the Flitetest forums I am posting this question.
I am currently working on a scratchbuilt 50" kfm4 flying wing loosely based on several other well know and proven dimensions just don't tell Chris Klick (for those who know who that is) lol. I have built several RC FoamFighters models that used kfm style wings and they didn't need any reflex to speak of but the general consensus seems be a default of 2-3 degrees reflex on any flying wing for the maiden that can then be dialed in. Is this the case with a KFm4 as it pertains to a flying wing? I have seen suggestions and rumors by some that no reflex is required on a symmetrical flying wing which would be great....less drag. Take it easy on me as my flying wing/delta experience so far only includes the aforementioned FF models and one scratchbuilt flying wing of my own design that did fly but had horrible tip stall characteristics leading to its ultimate demise. For those with more experience than I....how would you setup your flying wing for a successful maiden? To clarify this is a foamboard laminate build, flat as flat could be so proper "twist" is out of the question, reflex (if needed) will be achieved by means of elevon position.
