    Carbon fiber lift strut attach points

    As I have been browsing around for some lift struts for my pacer project, I came across carbon fiber masts for sailboats and have wondered if there has been any tested carbon struts on aircraft and what the most acceptable process to create attachment points to each end. I was originally...

    Cable routing, does adding a pulley change throw rate?

    In a closed loop aileron system, I see that I may need to add a pulley to allow for clearance of my flap pushrods. I have all my bellcranks in place and prefer to leave them where they are unless I really need to move them. The photo attached may give a better idea, but my main question, is...

    Lycoming 0-290 flywheel on an O-360

    I was wondering if anybody knows if one could use a flywheel off of a O-290, ream out the holes to 3/4in, index one of the holes for the stepped lug and install it on an experimental O-360? Are they made from the same blanks or is there any difference in strength/casting? Seems like the starter...

    Slotted flaps, am I on the right track?

    Not sure I my markings are dark enough, but I posted some photos of my recent flap design. Question: is the gap up top large enough to provide sufficient flow over the top of the flap? I notice that other designs have an inch or greater at full deflection, I assume lowering the hinge point would...

    Wing Layout for Pacer/Flap geometry.

    So I have started drawing out ideas for my extended pacer wing. Extending the flaps to 75% span with 25% chord. Ailerons will get 25% span with 25% roll spoilers. The concept is somewhat similar to the cessna caravan except with the stockpipp piper airfoil. Is this layout radical? Any obvious...

    Modifying flaps and ailerons on Pacer Wing

    Greetings, I'm sure I am not the first person to think about this but as I am constructing an experimental Pacer. I have just completed the fuselage by lengthening 20 inches and added PA-18 horizontal without moving the engine. As a result, I feel the fuselage is ready for a wing with enhanced...
