I'm looking at heat sinks too. Which ones did you get?

How are your mods working out?



mr.chomper -> RE: Walkera 5#10 (7/11/2008 7:40:40 PM)

I'm having tons of fun with this bird but it's also a money pit, mostly due to the fact that I'm a wreckless flyer.

My balance bar is bent and she vibrates a lot now, I've got replacements on order. If you want to see this thing fly fast (really fast) then take the weights off the balance bar, it isn't uncontrollable but it is really responsive. I've put the weights back on because I'm not smooth enough with the controls to deal with how fast it moves when the weights are off, but if you are an experienced pilot you should give it a go, its a blast.

BTW the 180 motor heat sinks fit and do a good job of cooling the motors. You can get 2 heat sinks on the front motor but I think you can only fit one on the rear motor.

So far I've broken:
1 canopy
1 set of blades
1 rotor gear (chewed up when motor backed out, make sure your motors are screwed in nice and tight)
1 balance bar (bent, but not totally wasted)
1 stock skids (replaced with super skids)
1 rear prop blade (I'm just going to remove it, though I have a replacement on order).

I fly like a mad man and I lack patience, but I'm learning that I need it because most of my crashes have been avoidable.

After reading this and other threads I will consider dropping in a lama "4 in 1" and battery to reap the rewards of the lama's better gyro. Not that I have a problem with my stock 4-in-1 but I'm using this heli as a stepping stone to a single rotor FP and I want to get used to messing with the electronics too.

All in all this is a great heli to learn on and a decent platform to modify.

I do have an issue, which is likely due to one of my gears being a little warn, that is when I spin the heli in one direction it goes up... when I spin it in the opposite direction it goes down. If the replacing the gear doesn't resolve the issue I'll have to look at adjusting whatever settings the 4-in-1 allows me to adjust (it may only be gyro gain). Either way if anyone has some words of wisdom for what is happening and how to resolve it... help a brother out.



Tedstrickland -> RE: Walkera 5#10 (7/11/2008 7:58:34 PM)

Could you please point to a source and part number for the 5#10 heat sinks. You said they were "180" size ???

I f/u on your recommendation for the Exceed LG from XHeli. They had free shipping yesterday....waa hooo !!!

Thanks....



mr.chomper -> RE: Walkera 5#10 (7/12/2008 2:58:29 AM)

The heat sinks are the xtreme 180 heat sinks for the lama's and blade cx's as seen here:

http://www.boomtownhobbies.com/Xtreme_180_motor_heat_sink_Silver_for_Lama_V3_pa_p/ea007-s.htm

I just picked mine up at a local hobby shop as the ones local to me all carry e-flight stuff. They cost me about $3.50 each.

Good luck!



ausaero -> RE: Walkera 5#10 (7/13/2008 5:13:43 AM)

Hi all,

Just wondering if anyone has had the same problem I have. I had not too minor crash a few weeks ago. 8 ft drop and damaged the main gears. Already had them replaced. However, after the repair, my 5-10 will no longer fly higher than 1 ft off the ground.
I'm not sure if the problem is with the receiver (3in1, Im using the 2.6 GHZ) or the motors. However my supplier says it must be the motors as he has had no complaints regarding the receiver. Ive also made sure that the pinions and gears are neither tight nor loose.

Any comments or suggestions would be appreciated.

Cheers,

Ausaero



AZheli -> RE: Walkera 5#10 (7/13/2008 7:18:39 AM)

Motors? Maybe

Does the heli rise straight up, or spin?

Normally, motor sets don't wear / burn out at the same rate so as to allow rise straight up at throttle up.

Bent Inner shaft?

Gears not tightened down onto shaft flats, allowing slippage & loss of power.

Ozzie air to thin to support aerodynamic lift?

Damaged battery in crash so it does not charge to capacity?

Get a spare battery & set of motors. Try the new battery first, then change out the motors next.

IMO, it just sounds like you're not getting enough power to to throttle up enough to fly...



Tedstrickland -> RE: Walkera 5#10 (7/13/2008 2:13:01 PM)

I agree with that approach....

I doubt you had damage to both motors from the crash. If one was bad, then it would spin....out of control.

The problem seem to affect both motors equally... I would try a new battery first. If no improvement, look for other issues that affect performance of both motors.

Do the motors get real hot after a shot time of flight ? If the concentric rotor shafts are bent, even slightly - then the internal friction will limit RPMs. This could burn out your motors real quick, as they will draw more current and overheat. It does not take much friction to really limit performance.

Ted



mr.chomper -> RE: Walkera 5#10 (7/13/2008 6:00:26 PM)

Ok, I've replaced my gears and... well I still have this one issue:

when I spin the heli in one direction it goes up... when I spin it in the opposite direction it goes down. One of the rotors clearly begins to spin slower when I do this (unfortunately I forgot which one as my computer is near but the heli is not). This leads me to think that one of the motors is screwey. I just don't understand why this would only happen when using the yaw control. Actually it does loose altitude when I try to fly it forward sometimes too.

Any ideas?



ausaero -> RE: Walkera 5#10 (7/14/2008 9:03:40 AM)

Thanks AZHeli and Ted.
I tried all 3 of my batteries and even at full charge, I'm still unable to fly the thing any higher than 1 ft off the ground. I reckon it really is the motor(s).
I have already placed an order for the motors and will update you guys on the progress.

Cheers




ausaero -> RE: Walkera 5#10 (7/16/2008 3:37:24 AM)

Hello again.

I received my new motors yesterday and hurried home to fit them. Unfortunately, I found out the the problem all along was not
the motors but the 4-1. I must have busted the upper motor controller during the crash. It was working intermittently yesterday
after the install, then it just deteriorated until it was no longer giving power to the motor(Upper).

I reckon, the reason why the heli wont go any higher than 1 ft off the ground was because I was not getting enough lift due to
the very minimal power being supplied by the 4-1 to the motors.

Anyway, my 5-10 is grounded at the moment because my supplier does not have the receiver in stock.

Would any one know if the HM5G4Q3 2.4Ghz Receiver (PN HM-5G4Q3-Z-22 Receiver (RX-2411)) would work on the HM5-10?

Cheers.




Tedstrickland -> RE: Walkera 5#10 (7/16/2008 6:17:38 AM)

The 5#10 uses the 2401 rx. I wouldn't try anything but an OEM replacement. I would recommend you buy another 5#10, and use it for parts. The cost to build a 5#10, strictly from individual parts is about $350 USD, so buying a scond unit is a far cheaper way to go. IMHO, you will probably use virtually all of it .......eventually. The only "spare parts" I would have on hand are the blades, extra batteries, maybe a vertical skid and a canopy or two. I have done 25 or so flights in the past few days, and the only parts I broke are the OEM landing gear, which I quickly replaced witth the SuperSkids 400. I am waiting for the Exceed Blazing Star skids to arrive, as recommended by another post.... Good Luck and Happy Flying. Ted

On my 19th fly my receiver burned, apparently is a known issue with the Blade CX2 controller.
So I tried a new thing: Used a Spectrum AR6100 Receiver, a futaba G190 gyro and two Skyborne 7A ESCs.
The trick was creating the right rudder/throttle mixing but after failures and more failure, I got it flying awesome.
It flies like never, I have some really cool mixing programs for landing, aleiron imput etc. I am very Happy with the resault.
And BTW, now I can use the standard 1S battery.


I am making this PM public in case anyone else needs this in the future.

I'm really interested in how the receiver and esc's are wired. I've got a HM5 #10 and a spare receiver just like the one you used that came with my DX6. I would like to fly the little coax with the same radio I use for my other helis. Let me know.


*4CH coaxial fixed pitch helicopter diagram*
Please note that the right rudder/throttle mixing is required for this to work



rogerwack -> RE: Walkera 5#10 (7/18/2008 10:17:14 PM)

I just received my 5#10 a week ago,and I must say after owning several e-sky heli,there is no comparrison!
Although the 5#10 is fairly stable for the first 60 seconds of flight on a 90 minute charge,it rapidly deteriorates, needing constant trimming while in flight! which only lasts a mere 3 minutes tops!

Compared to the Lama v3 and v4 both of which I have flown alot,and that were almost half the cost,I must say the E-sky Lama 3 and v4 blows this bird away IMO.

What I would like to know is there a battery upgrade for the 5#10 so I can get more than 3 min flight time?



RavenC -> RE: Walkera 5#10 (7/19/2008 7:09:42 AM)

I have never had a full charge give me less that 6-7 minutes of flight time. Perhaps a bad battery or charger? Having 4 batteries, I cannot comment on charge time, as I always have two ready. I think that would be needed for any bird. You did not mention the charge time and corresponding flight time for your Lama v3 and v4's, so it is impossible to see the "difference" as you do. Please elaborate for us all how it "blows away" the 5#10. Performance? Flight time? as an enthusiast, I would like to know.

Shy of grinding a few gears and blades, mine flies stable and fit throughout. Yes, you have to trim due to power drop, but, what electric heli doesn't? I do not find it a problem as much as part of mastering it's flight characteristics. I take pride in the fact that even with the power dwindling, I can still make a spot on landing!

Blue skies and happy flying!



rogerwack -> RE: Walkera 5#10 (7/19/2008 7:34:13 PM)

OK, after further inspection on the 5#10 ,I think one of the problems I didn't elaborate on is, when power starts to drop,and in my case this happens within 2 mins of flight time,the top rotor stops spinning when I try to throttle up past 3/4! So I checked out the gear and of course it is already stripped! Wow,after only about 8 flights,a little disappointing but I guess I should have taken the heli completely apart and checked eveything out first.I just wasn't used to having to do this on any of my other heli's!

I should also mention,I do really like the overall esthetic of this heli ,but for me the bling factor
will never out weigh the performance factor!
As for how does it compare to the Lama v3 and v4,well let's see,the Lamas were around 100 bucks landed compared to 160,but the 5 10 has more metal!
charge time is around 50 mins on the lamas,which uses a balance charger! compared to 90 mins on the 5 10.
Flight time on the lamas 7 mins on full charge,compared to 3 mins on the 5 10 ,my experience anyways, I have heard longer from others?
But in all fairness the Lamas are bigger heli's,and have larger batteries!
which brings me to performance,really hard to do a fair comparrison,because the Lamas are larger with bigger everything,they really rip it up!
So,from a cost to performance ratio,the Lamas win hands down IMO.
If you have never flown an e-sky heli,I would strongly recomend the V4 as the fuselage covers most of the heli,it is virtually indestructable,especially if you upgrade to harden blades!

I would say the 5 10 is still a nice bird overall ,especially for someone who is wanting to fly in tight spaces at slower speeds.



AZheli -> RE: Walkera 5#10 (7/20/2008 7:27:57 AM)

I have the 5#10 and also several Lamas. The Lama v3 & v4's give me a solid 10 minutes of flight, while the 5#10 does a little over 7. I have 2 batteries & both have the same flight time. The Lamas are bigger & fly a little longer, but you can adjust the lower "EXTEVT" for more aggressive flight controls. The 5#10 is quieter & more maneuverable in my office at work, so I bring it in every Saturday. Since it comes with all the metal upgrades you need to pay extra for with the Lamas, the 5#10 is a better $$ value. The only upgrade I needed to do was some larger & tougher skids, and also a set of the DX tough rotor blades. Some people use the SuperSkids, but I've gotten better fit & performance from a set of skids from the Walkera Blazing Star.

Tedstrickland -> RE: Walkera 5#10 (7/20/2008 4:26:12 PM)

I have yet to see any of the 5#10 issues mentioned. A full battery that has been cycled at least 10 times, gives me an average of 8 minutes of flight time. Only when the battery is at its end, do I see anything that resembles excessive need for rudder (motor A) trimming. This usually signals time for a new battery. I keep an eye on tightness and alignment of the motors (no gears destroyed yet...a bit of wear, however.....) a/w/a tightness of the blades (just enough to allow movement). Improved LG's and a few other minor mods added. Over 100 flights on my #2 bird, without so much as a hiccup The 5#10 is as close to perfect as you can get for a $150 ARF Co-ax with metal upgrades and 2.4gHz tx included. I currently have 2 and have 2 more on order, so I can try some more agressive mods.....Good luck and happy (greased) landings.... Ted



rogerwack -> RE: Walkera 5#10 (7/20/2008 7:17:29 PM)

Oh, one other thing I wanted to ask if anyone has experienced with the 5 10.
When I first tried to fly it,I did as I am used to doing with my other heli's, which is to turn on radio first then plug in battery on heli,but when I did this on the 5 10 the radio and rx didn't connect? I actually have to do this backwards from all my other heli's in order for it to work!
Is this how the Walkera heli's work? just wondering as this is my first Walkera?



Tedstrickland -> RE: Walkera 5#10 (7/20/2008 10:53:36 PM)

Are you referring to the 2.4 gHz versions or the older 72mHz ?? I have one of each and they are slightly different.

1. The 72mHz behaves like a traditional RC TX. The receiver is very sensitive to glitch, if the TX is off....always turn off tx after un-plugging the RX.

2. The 2.4 gHz "code matches". It also sets the trims when matched. The procedure I use is as follows.

A. Set throttle all the way down to zero, as well as the trim. (unless you want "Safety adjustment mode where the throttle goes to max at start-up),
B. Turn on TX. It will flash for 10 seconds.
C. Plug in battery, best if completed while tx is still flashing. It will code match in a few seconds. It seem the servos engage first, and a few seconds later the throttle becomes active.
D. IF you fail to code match....turn off tx and then turn on again (without unplugging rx battery). It should grab at this time.

I've never had to go any further than this.

Good Luck, Ted



rogerwack -> RE: Walkera 5#10 (8/9/2008 10:21:49 PM)

I just replaced a gear on the 5#10,and now it doesn't have enough power to lift ?,and yes I made sure the battery was fully charged! This is my first Walkera,and I can tell you,I am not very impressed comapred to the e-sky heli's



joshreynolds777 -> RE: Walkera 5#10 (8/12/2008 3:36:36 AM)

How does this guy fly outdoors? Will it get up and go like the CX2's and LAMA's? I'm wanting one, but concerned anout it being under powered with the 3.7V?
Any thought? Experience with this one and the other birds i mentioned?
Thanks, JOSH

Hi Roger,

I had exactly the same problem when I stripped my gears in a minor crash. After installing new gears, my 5#10 couldnt fly any higher than a foot of the ground.
Dont go buying a new set of motors or a new receiver. What you may need to do first is play around with the sensitivity control on the receiver. It is best done with the motors off load.

Once you remove the motors, you will notice that the motor that powers the upper blades is running slower than the one that powers the lower blades.
Play around with the sensitivy until you get both motors running at the same speed. Thats how I fixed mine. Unfortunately, I only thought of doing that I after I already bought a new set of motors and a new receiver.

Give it a go. Good luck

Cheers.

Ausaero



msdavid -> RE: Walkera 5#10 (8/18/2008 4:04:54 AM)

No doubt that the 5#10 is the best coaxial heli out there!! it its simply put "superior" -> http://jp.youtube.com/watch?v=jkXY9JBYs8Q



msdavid -> RE: Walkera 5#10 (8/19/2008 4:51:07 PM)

An exciting news. I found a battery replacement for the 5#10 that not only has higher capacity but it also has a higher discharge rate at only 8 grams cost.
The battery is sold by the guys http://maxamps.com/products.php?cat=28 , it is a 1S 3.7v 1550ma *20C* vs 1000ma *10C* for the original, that is a lot more juice. The battery only weights 8 grams more that the original (based only on the specs.. I do not have a scale) and the size matches perfectly in the battery compartment of the 5#10. I ordered one (Kamikaze style) and just finished trying it. IT IS AWESOME I flew for 12 min and still had juice left. The helicopter feels better when applying intense cyclic. The higher discharge rate, means that when the motors need more juice, the battery can provide it, so it reacts better to wide angle roll cyclic. I had to adjust the trim to pitch back because the CG is slightly to the front will fix it with link lengths later.

Hope it helps someone .. Attached some pics!!!!

dennorg -> RE: Walkera 5#10 (8/19/2008 8:13:44 PM)

I have a problem..when I turn on the heli and push the left gass-crowbar,it began to revolve about its axis.It`s impossible to control the heli now..
How can I fix this thing?
Can it be the problem that both sensitive and extent adjustment are wrong dialed?
¨Heli revolve about its axis like crazy!Same speed as blades.Can receiver be the problem and how can I fix it?
