Recommended control throws for Edge 540T
 

Hi All,

I'm getting pretty close to being ready to fly my Edge 540T, and have a question about control throws for those that have already flown their Edges. At the recommended "low rate" control throws, how docile is this airplane?? I ask because this is my first Giant Scale gas powered airplane, and all my previous experience is with .60 size sport planes (ie. Sig Four Star 60). So, will the recommended low rates be good for me for the first flights, or should I reduce them further until I'm comfortable with the airplane??

Thanks,

John

If your looking for the plane to be docile at the indicated low rates, you should move the cg forward to about 4 to 4 1/4 inches. When we flew the plane a 4 3/4 cg it was very sensitive on low and high rates. We moved the cg forward and it smoothed right out. The ailerons work just fine at either cg setting. I hope this helps, those used to large planes with sensitive surfaces will do well just where the plans call for, but it was too much for me

Hope this helps

I have my CG at 4 3/4 and I am using elevator throws below the minimums.

This is what I've been trying to tell people. If the plane is too sensitive at the 4 3/4" balance point reduce the control throws or put in a bunch of expo. Reducing the throw mechanically is the best way because that improves the precision of the servo.

Moving the CG forward deadens the planes response to control inputs and will make the plane harder to land. Better to keep the CG in a reasonable location and soften the controls.

Tom,

So you recommend keeping the CG at 5" for someone that wants a docile flying airplane, and reducing the control throws? Can you please recommend a set of control throws that would be appropriate?? Sort of an "Intro" level set of throws?? I'm afraid if I pick my own, I may end up with too little control authority! Ummm, I realize this is a 3D airplane, and this is an "unusual" request, but I don't want to re-kit (re-ARF??) my Edge on the first flight, and I can always increase the throws as my familiarity with the plane increases!

Thanks,

John

Mines at 5 inches, higher than reccomended throws, 60% negative expo. lands a gentle as they come, Futaba 9C.
Just floats right in, predictable sink rate.
Expo is the key.

RE: Recommended control throws for Edge 540T
 

CG at 4 3/4", elevator throws at 12 degrees max, expo around 50% (-50% for you Futaba folks. Don't get it mixed up or you'll have a battle on your hands).

It should be very easy to handle and still have enough authority to do some tumbling. IN normal flight we seldom use more than 2-3 degrees of elevator.

Can someone please tell me what the low rate & high rate throws are in inches?
