Huey can only get 11 inchs of the ground,help!
Don't know if i need a motor with more power.

Your going to need much more HS to lift the extra weight of the fuse and that big 3800mah pack with those skinny (Plastic?) blades!60% of the time, it works every time!

Yes try carbons. You will loose the scale 'look' but you will get much more lift.60% of the time, it works every time!

Might be worth considering Semi Symmetrical blades as well, you need more lift to cope with the extra weight.
Looks good though

i like you man.

this bird has a crappy hong kong motor in it ,all run the hs at 100% to see if the blades speed up the way they should.

you might be on to something .

12" is flying in "Ground Effect" - basically a cushion of air 1-rotor span deep.

I would look at the log in the Castle ECS and check the watts (power).
I would bet that the motor is not powerful enough to spin the head at the proper RPM and maintain the needed pitch

A 3S 3800kv motor just does not sound like the right motor.
Is this a 450 size? On the video, it looks closer to a 600.

One thing to think about may be to run 4S 2800mah. That will get you more "overhead" on the motor and you can run a lower throttle setting.

im with most others,,
by looking at the heli , it seems very unstable, like theres not enough lift ( ie ,, faster hs , and or cf blades should eliminate this and fix your problem , )

i do not think its the motor slipping on the shaft , and heres why,,
i dont think you would get off the ground,, and i dont hear no noise that even comes close to metal slipping on one another ,,and no chirping or anything, ,, but thats just my 2 cents
going pro , one crash at a time

A 3800 mah battery is almost double what is recommended.

So you've got a heavy battery and a heavy fuselage ....too much weight.

We'd need the numbers to calculate the head speed, but it sounds like it's too low... sounds like 1200 or so.
