Terence,

Sciencegirl has given good pointers. I especially like the part about winding harder. 50 cm of .109” (which is approximately .072 g/inch) should take 1,900 turns on the third or fourth winding. Of course, you’ll need to backoff turns to a launch torque of around 0.35 - 0.40 in oz initially to keep it off the ceiling. Probably reduce backoff turns and increase launch torque for subsequent flights.

If you have time to send the other specs I mentioned, we can give more help.

We are building in about 6 hours for a fresh team (we brought in 2 new people to have a second team at regions, two build sessions, total about 6 hours).

Of course that leverages prior year's experience as well as coaching team 1 this year, so things move along at a good clip.

15 hours and I successfully did it in one day. Had to reglue a lot of things because of how little glue I used the first time.

I have three workstations in my shop, so my schools build three airplanes in mostly one 8-hour day (usually a Saturday 9 am till 5 pm) with a couple more hours on another evening for finishing details. The three airplanes are two for the school’s A-Team and one for the B-Team. The B-Team returns on another day to build their spare.

Of course, there are other build sessions for additional variations in the airplane setup.

So far this year, my four schools have constructed 15 airplanes. It’s been a busy year.

this season but like our first actual plane like 1 week maybe even less and i mean it was good enough to not bomb so yay
it's not about the medals; go out there and have fun. make progress, learn a few things, have one heck of a time, because that's all that matters.

Does anybody know of a durable PORTABLE platform where I can tape down the full-sized drawing to? I need to transport the Wright Stuff kit back and forth between my partner and I. Would a large (but thin) piece of a cardboard work?

get foam board spray glue the design to it and cover in wax paper. that way u can also use pins to hold stuff down and get glue on it w/o ruining anything. also photocopy the template if ya can

I recently ran into an issue with nose down at initial launch with higher torque. I wind rubber band to 1.3 torque and then dewind it to 0.65 torque. When I released it, it will hit on floor after several seconds. Then I picked it up and launched it again, it will fly more than 2 minutes. I then do the same thing to wind torque to 1.3 and dewind it to 0.6. it will fly ok. so, why it cannot fly with higher initial launch torque?
