I'm picking up a used Atom 500 that is from 2009.

I'd like to know...

1. What updates are recommended?

2. What do I need to convert it the airframe to flybarless aside from the Compass FBL head?

3. What is a good sport flyer-mild 3D setup/head speed in stock 430mm blade config?

4. What is a good sport flyer-mild 3D setup/head speed in stretched 500-515mm blade config?

Any other caveats I should be aware of?

2600-2800
Start with 70% flat curve and see what u like, go from there.

Ice 75 should be perfect for Atom.

i guess whatever makes you happy, but I don't see how a 100% flat curve will mitigate overspeeding or underspeeding during loading and unloading of the head. I also think it puts undue stress on the power system.

Anyway, I'll be using a ICE 100 that I already have.

I have about 700 flights on my stock FB Atom(bought in late 08) built dead stock out of the box,so no updates needed.

If you want, a lot of guys have done the "grip flip" on the tail blade grips for leading edge control.I never had a single issue with my tail stock,but did it anyway just to see the difference.I myself didn't notice much but I am not 3Ding ...YET.But some pilots SWEAR it gives better control

keep the fact of trailing edge tail when setting up,took me a second of head scrathing during set up,only because it was my first heli with this.Really it was just the fact that I was used to the control rod going forward for right rudder,no big deal at all

I think my headspeed is in the 2600 range also.

as for curves I run a shallow V myself something like 95-92-90-92-95 in Idle 1 and 100-97-95-97-100 in I2.I have been involved in several "run it straight" discussions,and I just dont see the need to have the throttle at the same speed with 0 pitch as say 7 deg.to me it prevents overspeeding,and saves MAH.You are not getting any usable lift between say neg 3 or 4 deg and pos 3 or 4 so why have the heli screaming.Elec helis have almost instant response and torque so the performance gain is minimal if any but you will definately get longer flight times
