Here you go. The CG is set by measuring back from the front of the fuse (space between the spinner and front of the fuse) 18 3/4 inches back to give you the CG. I knew it was something different on how they measured the CG for this bird but couldn't remember how they did it until I looked at the plans/ins. As far as throws goes... no mention on what to set it up for. Set the throws as you would a trainer plane and give a little more on the dual rates and that should get you where you need to be. Make adjustments from there to your likings/feel. Hope this gets your LA1 in the air!

Mark (or others),

Slightly off topic, but... looking at the plans, it shows some pretty small control throws - 8-10 degrees on high rates. Is this common? I'd thought more along the lines of 10 degrees for low rates and 15 for high rates on the elevator on my Aurora. I'm getting ready to maiden her in the next few days and definitely don't want the throws too high. I was basing my throws on modern pattern ships...

Thanks!

Tim, These planes do not take much to put them through maneuvers. Remember, these things fly fast compared to modern pattern planes and have less drag. If you have a Tx that has expo. on it... dial in some for your set up and go from there till you get a feel for this plane. To much throw will cause these planes to be very twitchy and unpredictable. I would say 8 degrees for low and 12 degrees for high would be good for min./max throws on the Aurora. The reason I say 12 max is when the plane is slowed down.... sometimes you need that little extra depending on conditions. The rudder is the only control surface that uses a good amount of throw on these old birds. Everything else is overkill and most likely cause a bad "snap" or sudden roll out.

Thanks for the info Mark. Gotta dial down the throws just a bit before I fly her. I do have expo (Stylus radio), so I'll put in a bit of that too to soften things up. Now if the 30+ mph winds will die down.....
