Some time spent on my "light table" cutting up almost a half ream of paper...
Fun when you have to use 3 different programs to get prints... Acrobat Reader wont let me copy out the parts I wanted so over to Acrobat to extract the image and then into Photoshop to edit out the smaller parts.. Ctrl C, N, V and finally Ctrl P makes nice parts ready for the "light table". I played a bit with Illustrator to see if it would work easier but so-so results..

Hi jpt62: I noticed your test of the 25 showing 345watts at 35 amps. If the battery was fully charged before test, I'd suspect the battery is not up to the challenge or the 11/8/3 places way too much load on the motor. 345w @35a = 9.85v, way below what modern 3s batteries should deliver (closer to 11volts). Just asking and curious. Doug B

Ok time to pick the collective brain.. can we say Borg here? Looking at the wing retention system the designer has thoughtfully provided to attach the very long skinny wings, see attached picture. Now unless my math and keen observation skills are out of whack, Straight tubes going into aforementioned wings which are built withe the proscribed 3.5 degrees of dihedral are gonna not fit too easiely.. Question is... can I bend the fuse tubes up to make the wings slide into the fuse?

Nah. If I'm reading the snippet of plans correctly, you might notice the tube enters each successive rib at a lower point, from root outward. It would be a "good idea" to make sure each right/left rib pair has the joiner hole at the same position top to bottom, fore and aft (cutting each pair while the balsa "blanks" are held together should make this easier). With the joiner tube mounted squarely in the fuse, the wings should "self-rig" to the correct dihedral.

James,
I may have to mock up this area too see whats gonna happen. It looks like the bottm of the wing is gonna get scraped off or the sides of the fuse will. The ribs are sitting at 90° to the ground line. Wing is built on a jig which is supposed to "align" the AI, Dihedral and tip washout all at the same time....

Ah! I see what you're talking about, now!

Definitely worth exploring further...

The designer/draftsman certainly likes his abbreviations!
