I too saw it a few weeks ago. Typical Joe unbelievable quality. I will list a few of its unique features:
• This airplane is not the Berkeley kit, but is based on it. Lots of mods to make sure it flies well. It has flaps, I am not sure the Berkley kit had flaps.
• EVO 60 power
• Wing is D-Tube construction. I forgot the wing area and I am not going to guess.
• Elevators are open bay
• Stab is built up and sheeted. Flat, no airfoil.
• Motor bolts to an alum plate. The plate is fastened to the motor mounts
• All color paint is Duplicolor, top coat is Sig clear dope.
• Not rubbed out – a perfect matt finish was achieved
• That homemade 4 blade prop not only looks cool, it is functional, although it will not likely be the first prop of choice (or the 2nd or 3rd)
• Unique rudder hinge lock – more elegant that hanging a clevis and nylon horn out in the breeze. Involves a round machined part imbedded into the fix part of the fin, and has the rudder hinge wire passing thru its center. A pair of 2-56 screws lock the rudder to deflect to whatever angle is desired. Of course there are end of stroke stops to prevent the rudder from moving far enough to interfere w/ the elevator motion.
