T70 front five planes

[steve]

Good evening everyone,
Does anyone have a set of dive planes mounted forward of the front wheels on later T70’s?
Thanks,
Steve

No, but I do have two types of carbon-fiber pop-out airfoils that were used on a USAF glide bomb or missile. They may have been used on a Raytheon AGM-176 Griffin. One type is larger that the other, about the same as would be used on a T70 nose. Would this help?

Send me some pics when you have time for sure!!!

OK, here are pictures of both sizes. They are both a thin symmetrical profile that may be NACA M2. If so, it stalls at just under 10 degrees angle of attack and best lift/drag occurs at about 5 degrees. The largest airfoil is long enough that it could be cut in two to make one for each side of the nose. Since it is very thin carbon fiber/epoxy, a thin cut-off wheel will probably be the best choice. These are extremely light weight! Let me know if you think either would be useful. Regards, Neil

Here is a Griffin (not to be confused with the remarkable Rolls-Royce aircraft engine)
