have any of you fellow speed freaks expereinced this with noticeable trails at tips.
Would like to know at what speed and climatic conditions or mods to the tips this is or could be achieved
Don't know the actual numbers, but as I understand it you need moisture and a lot of dynamic pressure under the wing. Under marginal conditions
AFAIK they will appear at the tips only, increase the numbers and it moves along the wing to just about anywhere the high pressure air is exiting behind the surface and expanding rapidly. So my guess is that it is a function of wing loading and atmospheric conditions, and due to the wing loading of typical R/C models achieving this under high G manouevers is still not typical. As someone observed, it was in Florida with a large heavy jet, which it seems moved the pointers up both scales to the "possible" zone.
