[size=14.44444465637207px]the gyrobot 900 was great when it first came out, but if you're looking for the auto leveling feature, the sk-720 is better. I sold my 900 a while back and got the sk-720 instead. in the acro mode, the tail is too slow on the 900 and even with the auto level, it will cause crashes. the 720 does not have these issues, plus you can regulate the amount of auto leveling assistance, and switch from unassisted to assisted auto leveling mid flight, which you cannot do on the gyrobot 900.
[size=14.44444465637207px]the software is amazing on the sk-720 and the setup wizards make it idiot proof. on the 900, the set up is very hard to understand due to a poor translation from German.
