.4g seems like a lot for humidity, but I suppose it is possible. If you think it is because of the stabilizer, the CG would also be shifted back a good bit, I'd think. The humidity can not only make the plane heavier, but also softer, especially the motor stick. Caused our team some problems last year. Both of my Wright Stuff guys are making new motor sticks to try and stay just a smidge over 7g. for total plane weight, and be stiff enough to let them wind up the motor without causing disaster.I was wondering, is it possible for a plane to gain .4g because of humidity? I'm really worried because I replaced my stab, and that coincided with that weight gain. This seems impossible, because the original one was fairly heavy (broken and repaired), and a stab is generally a .4g piece, so it couldn't result in that kind of weight gain.
Also, (and this is going to sound weird) but even though pieces way weigh the same when put together I've noticed that they can sometimes weigh up to .5g difference. (again going to sound weird) It is all in how your pieces interact with each other.I was wondering, is it possible for a plane to gain .4g because of humidity?

My plane initally climbs really fast (while stalling), at a very high angle untill it gets close to the ceiling about 18ft. It then levels out and then decends. Is this normal? I feel that if the ascent is slower it would be better.
My plane is 7.0grams. Around .102 ish rubber, 45(15) winds, 1.4-1.5g. Fairly large wind chord. An ok number of winds left. The front of the wing is 1/8" higher than the back. Center of gravity is around the middle of the wing.
You should not need to add weight for that problem. You could carefully twist the tail boom to reduce the stabilizer's lean to the right (from the back of the plane) to see if this helps. If it does, moistening the tail boom piece near the motor stick, adding some twist, and pinning it to let it dry that way could help open the circle. BUT, don't try to make too much of a change until you see the results. Otherwise, I'd suggest carefully cutting off the stab and reglue at a lesser angle. The stab, being so far from the cg, has a big influence on how your plane flies. One reason we like to put both stabs and wings on with posts/paper rolls for adjustment.I have a question on my plane. We are flying relatively well, but it seems to be turning in quite a tight circle (about 10 foot diameter). This has been causing quite a bit of problems for us. We are using Ziegler's plane design, thus the tailboom is in a fixed position, making this quite difficult to fix. Do you guys happen to have a solution without adding too much weight?
