I was watching THIS (http:// http://www.youtube.com/watch?v=ousBMpklVok"") video yesterday and noticed that while in a constant banked turn that opposite aileron was being used to counteract an apperent over banking tendency. Is this common with everyone's XL builds. I also saw a short thread (http:// https://www.eaglersnest.com/forum/index.php?topic=2178.0"") about modifying their aileron bell crank to provide differential alieron control. I'm wondering if the took care of the over banking.
Also, I'm still searching for the post(s) about using a longer aileron control horn. I'll find it eventually, unless someone points me to it first. Thnx!

I'll be following along with ya on this... but keep in mind everyone builds differently... I've seen many without much dihedral and or washout... both of which would affect performance... I just wonder if over banking issues are related to wing profile or rigging... interested to see responses...

Bullet does this.. not to a great extent, but it is noticeable. There is no adverse yaw with the Iron Design ailerons, though. Initiate the turn with aileron, recover with rudder just like a cub. Bullet has both dihedral and wash out. From failing memory, I extended the horn driving the ailerons 1" because it seemed I was having to stir the stick quite a bit in chop. It improved that.

We set up DE Stubby and LEU Treehugger to have differential aileron movement by modifying the aileron bellcranks. Seems to work well.

Ooh, I would be into that. Do you have dimensions? Picture? I'd hate to have to think.. :grin:

Thinking weakens the team........

Here are pics of the aileron bellcrank on DE Stubby. LEU Treehugger has similar. You should be able to estimate the angles.

Thanks Tom. I did see an old thread someplace where those (or like them) were made at 10 degrees. So, as I understand it, differential ailerons is more about adjusting out adverse yaw. Did it eliminate the overbanking as well?

Thanks, Tom.. ahh, no thinking. My kind of job. :)

DE Stubby does not seem to overbank, but I don't know if the bellcrank mod had this effect - we never used the plan's version. Unless the air is completely still, these airplanes respond to air currents, turbulence, so flight corrections are often required.
