Wright Stuff C

[madhavaniyengar]

Hey guys,
I'm having some trouble with my plane. When I fly it, the rubber seems to be getting bunched up at the front hook, causing the flight to be very unstable and not reach a very high height (maybe 10 feet off the ground). I put about 1000-1200 winds in a 3 gram-ish rubber motor, .094 in thickness (I don't know how accurate my scale is, seeing as I had to add 0.3 g of clay to my plane at regionals when I thought it met the 8g requirement).
Any suggestions on how to fix this?
Thanks.

your motor is probs too long or your hook to hook must be hella short
thats what i could think might b the problem

I'm using the FF plane with an extra 2 in added to the motor stick, so idk if the hook to hook distance is the problem.
I'll probably experiment more with different motor sizes. What mass/thickness works for u guys?

sry cant reveal that on the behalf of my team
but most ppl i heard are using around 2 gram loops

Oh ok. I was just looking for a range that I should look to test in. I'll try around 2 grams. Thanks!

lol sorry i just dont like to reveal my teams info
but yea give it a shot

I've decided this is a very frustrating event! My plane flew 2:10 at an invitational a few weeks ago. The limited practice time I can get in a gym I could only get it to 1:33 last week. I said that will have to do for regionals and I did everything exactly the same sat at regionals - and it flew for :40

This is my first year doing Wright Stuff. Is this normal? Should I expect this kind of variation? I don't know how the same trim, same rubber, same winding torque can result in such different times. The only thing I can think of is that something changed on the trim and I didn't catch it, but I carry it in a box complete. I don't pull the wing or stab on and off and I have marks for each of the settings so I just don't understand. If this is normal I'll try and reset my expectations, but it just doesn't fit with "science". Sorry to vent, not sure there is any answer here. Our team did make it to state, so I need to figure this out in the next month.

If you use the SAME rubber as before, rubber degrades over time so I suggest you change to a new rubber band.

If everything else is the same (no movement of the LE and TE of wingpost), it must be the rubber. While I do not suggest using brand new rubber, it should also not be a much used one. The power it holds degrades with #of uses. That could explain what happened. We have also noticed this a couple times. But yours is too drastic thought

We got 183 seconds (recorded as 181 seconds) in the Bay Area Scioly competition held on March 2nd.
