I totalled the new set of FB blades in no-time and fitted the symetrical blades within the first 15 minutes. The first thing I noticed was that I need way more collective to approach a hover but that once airborne, the heli was WAY more stable than before the blade change. I looked through the forums but couldn't find any discussions on why this might be the case. One thing I will say to other beginners is, if you think you are serious about mastering your bcp and are still on the stock battery pack, run to your nearest source of Li-Po battery packs and upgrade! The added filight time will go a long way to reducing your frustration while you learn. I'm not sure if I really needed to go with the beefier motor or not. I do know the heat sinks are a must-have, as is the special Li-Po charger.

The "upgrade" motor is not beefier, it is the same motor but with a different pinion gear. The reason is that with the higher voltage Lipo battery, you need to reduce the load to limit the current. The stock motor will fail quicker if running on Lipos.
I think the improved stability is due to a higher rotor speed.
