i just got a hummingbird a few days ago in a trade. my problem is, the heli wont lift off the ground at all, even will it fully powered up. it will just push itself around on the floor. has anyone else experienced this? if it may be a setup issue, could you post pics of your setups. i tried to make sense of the directions online and im confused. any help would be great. thanks all.

how new are the batterys?
that would be the first issue..old, dead batterys wont provide enough power to lift it up

gretzky6869

1 battery is used, and the other 2 are new. im confused as hell[&o]

xxguitarist

how long are you charging them for, and on what charger?

gretzky6869

its a wall charger and till their a bit warm but not hot to touch.

xxguitarist

somewhere around 1.5 hrs?

gretzky6869

yup. each battery will last a bit of time under various levels of power to the blades

xxguitarist

do the blade spin really fast, just not lift it off the ground, then?
if so, try bending them (gently!) so that the angle of attack is increased..

gretzky6869

yeah i tried that. im going crazy could it be in the setup at all? i dont really know where to begin other than the basics

xxguitarist

uhhhhh unless the paddles are at like negative 20 degrees attack..? or there is a huge chunk of lead weight...i dont know what to tell ya, they usually like to fly in some direction. usually towards the nearest hard object

gretzky6869

can you get a pic of your setup and post it? maybe i have something setup wrong.

i just recently reformatted my hard drive... have yet to reinstall the digital camera software (so, sorry, maybe tomorrow or something), however take a look at this [link=http://www.centuryheli.com/products/helikits/cn1020_hummingbird/views.htm]HB Pics[/link]

maybe your brushes are dead

gretzky6869

not to spund stupid but what do you mean? im new to electric.

My Feedback: (4)

thw brushes that go in the motor could be worn out which would mean you would need a new motor. i would recomend getting an acro 280bb motor since its brushes are replaceable

gretzky6869

next q is where do i find it? i have heard of them before though

My Feedback: (4)

maybe at a hobby shop or many rc heli or airplane web sites.

If you buy the 280bb will it last longer than the stock motors because i heard like the tail motor on the aerohawk gets only about 10-15 batteries before it dies and you have to buy a new motor.

hummingbird (dragonfly) has been flying well for a couple of weeks and after a bump the rear rotor is full on. It seems to be the speed controller. I disconnected the speed controler from the receiver and it still is full on. Of course when I disconect the speed controler from the rear rotor it stops. Can this be fixed or is the feda mixer speed controler fried?
Thanks for your help.

weight? bad motor? bad esc? could cause those problem!

Jerrykl720

also the pitch too!

I had exactly the same problem as you after trying to adjust the main blades pitch. Never could get the blades back to a shape that would give enoug lift to get the heli off the ground. Changed motor, batteries, checked setup and paddles all to no avail Put on new blades when I could finally get them and bingo, off it went. Put old blades back on and nothing.So if you bought this thing second hand and the previous owner was trying to improve performance by screwing with the rotor blades then you likely need new ones.
Good Luck
