Just wondering if anyone has first hand, before and after, experiences with flap gap seals. If I can gain 6-8knots for 500$, I am all over it. Also, there was a company called Smith Speed Conversions that I keep hearing about from fellow bonanza owners/old timers. The claim is that this company produced mods that gave the bonanzas 25 knot cruise speed increase due to the reduced parasitic drag. (I am skeptical) I have searched and searched and cannot find anything.
