Hi,

I've just gone separates and brushless on a stock Feda/Hummingbird, quite a job as this is my first heli and it had an all in one board I even had to resolder the servos, modify (butcher) the chassis and crame it all in.

I used a HLG200 Gyro, Pheonix 25 main ESC, Mini AC 1215/20 brushless motor, Pixie-20P tail ESC.

But atlast after even having to put the gyro on its side (didn't say anything about that in the manual) it all works and wow it work great. I can fly the thing fine without every 15 seconds it heading flat out towards whatever will do it the most harm or of the highest value. No longer does it keep full power 2 seconds after you've shut it down.

So next on my list is a better battery???? Lithium Ion/Lithium Polymer anyone know what the difference is?

Also I think if all goes well I could fancy a Piccolo Pro sometime in the future so I'm after a battery I can use on my Hummingbird/Feda and on a Piccolo Pro. I think the Piccolo Pro needs 10.8v battery (but I could be wrong) will this fry my tail motor?

Can anyone who has gone this route offer any advice re batteries/charges/suppliers etc.

Cheers,

David

Hi mate. I tried a 2 cell (8.4v) li-polly (forget li-on)on my hummingbird...

Stock motor - it flew for 20 minutes!!!

Brushless, separates - would hardly get off the ground. You need a 3 cell setup. Either E-Tech or Kokham High Discharge cells - go to www.b-p-p.com they exlapin all.

You can buy a charger for about 50 dollars for these, but I spent the extra on a Triton as it also charges and recycles all my nicads , nimh's and lead acid batteries and it way cool

Dodgey99,

So a 3 cell 1020mah 10.8v pack and you can charge that on the Triton charger and get 20 mins flight time?

I think I know what I'm going to spend next months money on already.

I really am amazed how much better the heli flies now. Its incredible the difference in handling and performance. She sits rock solid in the air and I fly for the full lenght of the battery before having to land.

This could save me a fortune in parts.....

Another thing I've noticed is the stock tail motor hardly even get warm now. Although it must be working far harder. Before I'd fly crash etc etc so hardly any prolonged use but now constant for say 10 mins and its cool to the touch.

Cheers,

Can you show us some pic's?

Dodgey99

Yep! I got a bout 20 mins.

10 mins, then break for a minute, then another 10!

Good to hear the separates are working well. My tail still gets very hot!

Got my HLG200 on the way ....

Hi,

Charlie, Sorry I haven't got a digital camera, another thing to add to my list of gagets to buy, so I haven't got any snaps.

Dodgey99, Your tail motor is still getting hot? Strange mine hardly even gets warm now. I've got a B2C motor (don't ask me what B2C means I have no idea) on the way and a direct drive prop for the tail so I'll let you know how it goes.

The props for the tail are only $0.89 so much better value if it works.

Another thing I've noticed is although I hardly have any crashes compared to before now when I do crash it is usually quite catastrophic, saying that though I haven't broken anything yet. (famous last words....)

Cheers,

Dodgey99,

Forgot to say I posted this about my HLG200 you maybe interested or you may already have it sorted but here it is :-

"I had the same problem, basically from the front you want the orange wire to the right and you DO NOT connect the other two wires I cut mine. the reason I think is that otherwise the tail ESC will try and provide power to the receiver but this is already being done by the main motors ESC.

Also the manual that came with my HLG200 was for the HLG200 that comes in a proper plastic case but mine is the lightened one and it needed to be on its side so the CSM writing is sideways not up the correct way although the manual didn't mention this. Well I couldn't see it anyway. "

Let me know how it goes?

Cheers,

David
