Yes that was me, the picture is on page 10. Is it only my computer or is that picture super large? So far everything seems to be running ok, knock on wood. I do have a 30A ESC I bought for another motor as a backup but I'll just monitor things for now. When I used this battery with the stock motor it ran very hot and finally died. I disassembled it and the coils were charred and one brush was almost completly gone. Good thing I didn't damage the heli.

Hi there
now I continue searching for brushless and esc for my Df#37
please any info about it. this is my first experience getting one.

The 60 guys are having good luck with this combo... it's a great price too.

maybe you can pick one of these up instead?

W37 Cepeda

It looks nice, I recommend something with a little more pep. That's the reason you get brushless.
Go for the other one , it has 4200 RPM.. you should be asking yourself at what RPM level
is the max before you have to adjust your yaw. IT's not a matter of just poping it in,
some of us got lucky, but when so much power is applied, you will need to do some adjustments.

Hi, guys I have found out about the metal rotor head and tail sections. It is the same as the 60 so if you want then then look at buying it from a good website for a 60 and it should be done. Mine is on it's way and I will up date you on it's fit and function.

soneebee

hello W37, the head that army posted for the DF37 seems to be very good.. I can see that it is a good copy of the Align SE head design.. is it already out in he market.. the one you posted is like a promo for the whole heli.. are they selling just the head part? I hve talke to eHirobo about the head and I am not sure when the head for the DF37 will come out.. but i think walkera will still make the head for this heli....

W37 Cepeda

METAL HEAD NEWS FOR DF37.

ACCORDING TO WALEKRA. THERE WILL NOT BE A METAL HEAD DESIGN FOR THE DF37.

THIS IS BAD NEWS.

IN ORDER TO GET METAL HEAD , YOU MUST PURCHASE A AFTER MARKET SYSTEM,

THAT MAY REQUIRE MODIFICATION.

SPECULATIONS REMAINS ON WHETHER THE DF60 HEAD COMBO WILL FIT,

THE ONLY ISSUE WITH THE DF60 SYSTEM IS THAT YOU HAVE TO ALSO

ACQUIRE THE FLYBAR FOR THAT HEAD, CAUSE THE ORIGINAL FLY BAR ON THE

DF37 is ABOVE THE MAIN ROTOR.

AND SECOND, THE MAIN SHAFT NEEDS TO BE VISUALLY AND MECANICLY

VERIFIED TO SEE IF IT FITS AND CONFORMS TO THE DF60 SYSTEM.


Here's a link to see the DF60 head system on ebay:
http://cgi.ebay.com/Aluminum-Alloy-M...QQcmdZViewItem

soneebee

the one that eHirobo sent me contains the flybar and the shaft already.. and the head is already assembled.. the only problem that i am seeing is the shaft.. the one that comes is designed for the main gear of the Df60.. I havent seen the actual DF37 gears so it will be the point of problem.. other parts might work

armycopter

Somebody is making a metal head for the 37. Here it is as an entire assembly....

http://cgi.ebay.com/RTF-ALL-Aluminum...QQcmdZViewItem


I emailed the vendor to see if I can get just the head, I'll let you know.

Soneebee didn't indicate that this head was exactly the same as his DF60 head, but seems to be more like the Align.

-Mark

soneebee

Mark this head that you posted really looks good an not like the one on the Df60.. it is really more of the AlignSE head.. it looks and has the same mixing.. so I guess this is like an align copy.. the one on the DF60 is really different.. even the mixing is different... If I were to choose between the Df60 head and that one.. the one on the Df37 seem to be better looking and the performance seems to be more of the aligns...

W37 Cepeda

You are wrong. Sorry to say it.. that will not work.

If you take a closer look, that is not the DF37 HEAD.
THE DF37 has the flybay over the mains.. That what you see there
is a TrEX450 and or simular DF60 Conversion.

Beleive me when I say... no one has a DF37 original head in metal.

But I give you credit.

Because it proves according to the pics, you
can adapt a DF60 metal head and flybar to the DF37.

armycopter

Let me rephrase... somebody is making a metal head that will fit the DF37.

W37 Cepeda

What remains to be seen and fact finding,
is to figure out, what is more beneficial.

The flyBAR. whether over the main rotors or under the main rotors.

I have to figure this one out. I'm sure there must be a difference.

All I can say is this, and not too defend the DF37, but I flew my friends

TRex450.. and it was not as stable at low hover as my plastic head 37 with the flybar over the mains rotors.

It seems that flybars over the main rotors achieve better balancing than under. could this be true?

This remains in my book as a real study issue.

Heliwannabe

What a nice looking deal. The price looks great considering the upgrades but ouch! on the shipping. I'll be keeping an eye on this as my plastic parts grind away.

balance_mind

W37
I think I agree with you that there will be a difference whether the flybar is below or above the main rotor.
I'm suspecting it gives better hover but maybe a dropped of performance in terms of reaction speed on turns and pitch control.
Well guess we need to further study on this.

Army
that combo looks great. Finally a CNC head for the #37. But like what W37 says, it's not totally a true head for #37. I guess the vendor must have modified it to fit.
But worth keeping track on this combo. Do post us the results on your queries to the vendor.

mcdaniel

hi there

well finally I crash my heli ,I hope you can help me,Everything is good only problems with main rotor blades.

so now I have two main blades in my hand.

so I need :

rotor main blades.

the main blade holder are good no damaged but a metal shaft for conected two main holder is broken looks like principal axis(I not sure), it seen that also come with bearings that are missed also. the two ball linkage set that conected from two main holder are ok. so it seen that with rotor blade, bearings and this metal shaft I could fly again, so in the df#37 parts I dont see this shaft ? which part number will be ?or maybe it will come include in blade holder item.? the bearings is in bearing set part?
thanks I need that you tell me exact items that I already need, to place an order.
Thanks
ps:Good price for brushless and Esc on HIrobo ,I will get this combo.
thanks Armycopter

I have asked you guys this question a couple of weeks ago on the thread.. and I think no one has been thinking what is the real difference.. The only thing that i can see theoretically is that when the flybar is at the farthest point of the CofG the response time will be faster cause the effect on the gyroscopic forces is greater than when moved it closer to the CofG but this is theoretical.. since i have used both head on the same heli I really cannot compare.. the CNC head on the DF60 is very responsive eventhought the flybar is at the middle.. the only thing that i can see advantageous with the blades farthest is it can lessen the possibility of boom strikes.. when i got the original head on teh DF60 i had 2 boom strikes just because of a bad drop or landing of a foot or so.. but i did it with this head well it did not hit the boom yet..

Cepeda found that the Align feathering shafts fit the DF37 and they are less expensive. (plus you get 4 in a bag). Also, if you look on page 8, he found out that you can use the align blade holders, bearings, etc and they are of higher quality (metal blade holders).

If you simply want walkera parts, I think this is what you'll need... (see pictures)

The shaft is HM-037-Z-09

soneebee

mark.. are the head assembly of the DF60 and the Df37 the same.. i think they are... I have tried the feathering shaft by aling this are better than the ones walkera uses. it is harder and mot robust than the walkera.. and it comes in pack of 4.. but havent tried the blade grips yet.. but i think they are also interchangeable

armycopter

soneebee,

cepeda tried them and they work for the 37. I'm not sure on the 60. On another note, you inspired me to go try nose in hovering this morning. I went through a battery pack with more success than failure so I'm pretty happy. I need to get the nose in thing down if I want to continue this hobby. Hopefully I can get good at it. After that I'll try some fast forward flight and figure 8's. I can do slow forward flight from side to side and good "tail-in" hovering but that's about it....

soneebee

that good mark since you can do almost all that is written on the book.. after nose in then you will going inverted... that will be something....

mcdaniel

Ok the parts are ordered , also the brushless motor and ESc from E-hirobo
we keep in touch when everything get to me ,
thanks again ARMYCOPTER
