i am new to the site and just thought i would give my thoughts on this heli. i have flown a few times at a shop where i work and have found the heli will not stay in the air whaen driven around the room. having said that i will tell my plans on improvement. i plan to put holes in the blades and tape the under side like someone posted earlier. and also i might shorten the blades and tail boom like also metioned earlier and i have a lithium batt on the way for more power and longer flight times. the batt will be constructed out of old cell phone batts, i guess thats the cheapest rout. and olso use an old desktop cell phone charger to charge the packs. and if all that does not work i'll increace the motor size. but so far the kit is nice and alll the upgrades i've mentioned should not cost more than 40$ so i am happy with the kit and i still fly the kit as much as posable to et a feel for the bird. i don't think the bird is too unstable to hover in a 3 foot radius but it does need a little more power to get more response from my inputs. ill post later to let u know how it turns out. but i should have a profesional heli after all these simple upgrades. graet site and keep the good ideas comming. thanx, bond, james bond
