A few quick questions -

About my stock #36 gyro - there are 2 small dipswitches on the bottom of the case - one I think for reversing the gyro direction and one which is unmarked, anyone know what it is for? This is the WK001 gyro.

Also - at about 40% throttle I start to get a slight wobble in the heli - this disappears as I continue to increase the throttle through 50%, is this normal? - it doesnt affect anything in flight.

Last one (for now ) - I am currently running everything stock except for a Lipo battery - I've got about £200 to spend - what should I upgrade first, I'm thinking radio gear but what falls into my price bracket - Im looking at either Optic 6 of the Futaba 6 EXH

Any advice greatly taken !
