Some excelent shots on Flightglobal's site Inky! Thanks for the link. John, those plans are out of the Kookaburah technical manual on the Whirlwind. Although quite good, a lot of the smaller details just aren't there or very blurry to say the least. Can you figure out that articulated elbow on the landing gear lockdown arm? I sure can't. Been trying to find the 4+ book to see if it has more info but no luck so far. Thanks you guys!!!
