014 there is 'extra' mass in the over-built main wing; including the unnecessary use of sheeting and an over-use of webbing in the (outboard) main spar structure. in most cases, the use of hoerner wingtips on a model wing is not recommended. as seen here, however, the elongated hoerner wingtips 'simulate' dihedral. (as is done on certain versions of a j-3 cub wing.) the mass of aileron servos should be located just forward-of thirty percent of chord/the main spar, and as a far inboard as is practical. ( Model designer's mistake. ) 026 there is extra mass in the excessive structure at the wing mount. this mass and the excess mass in the main wing Raised the location of the model's c-m. center of mass. see my tutorials, if interested. correct location of c-m is indicated in the linked illustration. the design of the tail boom structure may be scale-accurate; but it is less-than ideal. specifically, there is a shortage of transverse miter bracing in the tail boom, and there is an excess very slender bits (and joins).
Well, done, Mr. Dan 👍 you are good at everything you built
Beautiful build Dan!!
I believe the balance was not that good moving the battery forward should’ve fixed the problem, right
certain excess structure/mass is actually located forward-of the wing mount.

From what I've heard and read. The full size glider wasn't much better, especially loaded up.
