Next Project is to Revisit PX31- with its update PX31-A





the Original PX31 has gone through 5 design changes till it performs right.
the PX31-A has gone through 3 Design Changes , since I deviate from the original. LOL Bad idea. but every time I return a design feature back to the original . the flight performances improve.

Lesson , if the design is good, dont change it on your later versions.

Note: im at the limits of what the material can handle. at 45inch span w/ No Carbon spar (unsupported) , AUW weight with payload 650g-790g

any bigger or heavier carbon spar is mandatory.
