Status: offline 		Yer its fantastic they'r a bit better than me at flying the damn thing than me though.
Its my 1st chop so prob should of gone for something a little more afordable.
However reading all the postes here it seems the more expencive it is the easyer it is to fly
Still im having a hell of a time setting it up as soon as the swash plate is level i bin the thing and bent the head
Its extreamy strong, I havn't broken anything yet apart from blades that is totaly understandable.
Unly complaint is that the charger has no auto shut off so you could blow a battery up and burn the house down

Status: offline 		sure ! it was my first one, and always the more interesting one for me ! I know walkera brand very well, I retailing them all, and this one is like special anyway, it is my only real feeling of CCPM one.
Also, take care, often users are crashing and benting the HM040-040 part, and do not see it at first.. after they wonder why not flying so well... this part is often bent, the HM040-040 is a must to have in stock, and bothering to change a bit at start of learning, it bent nearly at each strong crash.; take care about it. it is inside, not possible to see it directly, it is in head rotor, between blades, but if you take the 2 step of main blades and feel they move arround together a bit, need to change this part.. it makes crazy tracking and vibras

Status: offline 		yer i've just been bending it back
It has been geting worse so I will replace it soon. blades are balanced at 1st but as you wack the power on they go of line by about 2-3mm so causing it to vibrate.
also my elevator servo is twitching that won't be helping matters.
Oh and Im prety sure the tail motor is burnt out. It only turns slowly after I give it a kick start otherwise it dose nothing.

Status: offline 		yes, sure it is dead... so small motors need to run so fast in charge, there is nothing magic.. need to change sometimes..
Also, I tryed several ones, but never direct drive... I have a direct drive kit, maybe I'll try when I'll have time.. I'll see. . .

Status: offline 		Hi long time since I posted last sorry.
I have fixed tail rotor and it is a much stronger feeling motor.
I have also been hitting the hirobo parts bin hard. I have a brushless motor, carbon(ish) blades and 2200 li-po.
However I am bloody confused as to how it all wires together.
I have the three actuator loose wires pluged into the motor, the block connector is in the battery. but the plug that goes into the recever is the one that has got me.
On the #36 everyone seems to put it in the 3rd slot down and it dose beep at me when I do this but with the obviouse reaction of one of the pitch survos going 2 sleep as it is normaly ocupied by sed survo. If I plug it into the Idle bottom 2 slots it dose bugger all apart from power everything else but with nothing from the motor.
Please help!

Status: offline 		update. It still won't work but I can give more information that may help someone help me.
The tail motor makes a screeching noise with no movement as the power is laid on when the brushless main motor is atached through one of the idle slots on the recever. If I disconect the brushless main motor and reatach the brushed motor to the 'motor out' wire they both work fine.
If I connect the speed controler to one of the pitch outputs of the recever everything works fine (apart from the disconnected survo obviously)
I hope someone can help

Status: offline 		hey jahshappybus

any update if you got the brushless to work on the DF40. I guess i see what you are saying and it seems that the 3-1 RX of the DF40 does occupy all the first 3 slots of the ESC for the 3 servos slots 4-6 have nothing in it. but if you plugged the ESC on the 3rd slot it will engage the throttle for th brushless but you will be lacking one servo. I guess you have to do some modification on the ESC. I think I have seen on one of the posts what he did to mahe the brushless set-up to work on the DF40, he modified the ESC board shorting something to get it to work...

I have this pic that may help
http://image.rcuniverse.com/forum/upfiles/180571/Bz77786.jpg
the little resistor (bottom left edge of bottom board in front of micro chip) is disconnected from the top board.
still won't work
however with the brushed motor I have had some flying success and it is a lot of fun!

Status: offline 		I have been trying to hover my DF40 for a couple of months now but still it is very hard to make it steady. with all the adjustments I made mechanically it is still not that easy. I guess the design of the DF40 is really that hard to fly.. I think most of the problems I encontered was the design of the head assembly.. the hiller head is not that responsive and the plastic head design gets alot of slack I think they have to make an alum head for this heli to get it more stable at hovering..

have it all documented in the other forum.. heres a link if you want to look at it.. there are also some bad video i took were my DF40 just skips and jumps like a bunny rabbit.

Update on the upgrade I have done it!!!!!
well sort of
I noticed the resistor running across the micro-chip on the pic isn't present on the board so I soldered one on and it works.
It runs fron the 2nd leg on the left of the chip to the left post of the 4th plug as you see it on the pic.
Unfortunatly I don't own a pin soldering iron and as a result one of my survos stoped working because of short circuit.
I fixed this easily enough but confusingly my tail motor has packed up again.
back to the soldering I go :-/

Status: offline 		what is the performance of the brushless motor on the DF40.. how doe ist fly now? is it any better? I am still not able to fly my DF40 as stable as my other heli but it seems to be promissing.. I just have to do some more adjustments I guess.. the mechanics on the hiller is not good the response is very slow.. the cyclic is unpredicatble.. I think there is a problem with the DF40 head that is why I am having alot of unwnated movements I'll check on this when i get the time . post the pics on the upgrade you made..
