I have a couple of sets of FMA copilot II and also just fitted 3G to my 600.

Just wondering, *hyperthetically*, with the right software upgrade, could the 3G hardware perform flight stabilisation like a CPII

(of course non-inverted since there isn't a vertical sensor!)

Surely the 2 gyros could hold your heli level with hands-off cyclic? or are the gyros not up to the task in the 3G (with a hyperthecial software upgrade)?

Or does the 3G do this anyway (i've not properly test flown the install yet!)

Buy a Gyrobot 900, that will do both fbl and (co pilot style)stabilisation.

I have used it and it is great

gyros drift over time. You really neew an IMU to do the job properly

I realise it wouldn't be perfect,
of course you'd get drift anyway without GPS or the optical system HC has,

just wondered whether if it had the software whether it could auto-level itself when you centre the sticks (like on CP).

I realise there are other products out there that would do it, so no need to suggest them

Just a though exercise, wondering whether the technology/hardware is essentially the same

It has no idea what level is...that is my point.

it would know level when the system switches on (assuming your heli is level).

There is a guy at my club that has built hos own self levelling system (principally for aerial photography) and it has GPS (positioning), ultrasonics (height), infra red (horizon) and also a triple accelerometer for x,y,z drift but I told him the same as I told you, just buy a helicommand pro or a Gyrobot 900, it's a no brainer...

happy flying...

keep away from gyrobot if you want self leveling. its leveling is not as it was advertised. it uses the accelerometers when the heli is on the ground, only gyro data is available. you correct it by small perturbations, but if you leave the stick off it drifts..
