I just want to add that if you want to add a gyro and you are using an unregulated LIFE rx pack, make sure your gyro can handle the higher voltage. For example, the Eagle A3 is rated up to 7.4 volts, which is fine, but some others are only rated to 6 volts. They might be OK, but I would definitely check with the manufacturer first and not assume anything.
I totally agree with Dick about using gyros; I'm pretty sure rowarrior had tongue firmly in cheek
, but it's amazing how many people actually do think that using a gyro is "cheating".
