Anyone else ever noticed how the Great Planes individual hardware packages (2pc clevises, screw lock connectors etc...) seem to catapult their contents across the room if not handled properly. One slip of the finger and that tiny piece shoots across the room never to be seen again. Anyone else notice this? I think it's a selling tactic!

This came up when I was adjusting my throws on my pizazz and installing some new screw lock connectors. How much throw is generally needed for "3D" performance. What about ratios of stab/control surface etc?

Thanks!

haven't noticed the parts flying. Played that game when building furniture with imported hardware and screws weren't available here. Paid some $20.00 or more shipping fees for 4 screws (OUCH). Learned to open them over a tub.

3D throws are 45% each way and from 80 to 90 %expo. Your values may be different.

45 degrees each way is a good starting point, some planes need more and some can get away with a little less.

I use around 20 to 40% expo depending on the plane.

I fly using this rate all the time, no DR switch.


For the maiden flight I use a lower rate but have the normal 3D rate ready just in case I need it, which I haven't. Just an old habbit

I don't use expo at all! What's it for? I can do rudder taps, and tork rolls without it. I guess I never understood it well enough to try it. Might start a new thread on it?

Expo is really not difficult to understand. All it does is soften the controls around neutral so the controls feel smoother.

I never used expo either until a few months ago. Once you get used to it you'll never go back

Felt weird at first, but it's the only practical way to fly a plane with 45 degrees or more of throw without using a dual rate. I usually only run 20%, just enough to make the plane flyable at higher speeds.

Actually it takes about 20% expo to make the surface linear. That is because the servos motion is an arc so the effective travel is less at higher deflections. I don't mean to confuse anyone but just having a little expo really smooths things out.
