Eagle50
 

I have just purchased an eagle50 and i am having problems setting it up. When ithrottle up to check the trim the heli suddenly has a short burst of power and heads skywards. i am a newbie, so if anyone has some advice keep it simple.

RE: Eagle50
 

So you need to start off slowly since this is a 6ch and you're a newbie you're starting the hard way. Fly tail facing towards you all the time. slowly spin up and fly by doing bunny hops. You can find out what's bunny hop by watching the exceed g2 video.

RE: Eagle50
 

Thanks Andy, I have also got a Walkera 4 which Ihave been flying ( allbe it very basic ). My main concern is the motor surge. I have the throttle trim on minimum and all other trims are on about centre. The PLT is at 12 oclock and and the PIT is on 2 o''clock. The limit and delay are also on minumum. Could it be the receiver or the transmitter. The receiver is very hot after these surges. The heli is brand new.

RE: Eagle50
 

The dip switch on the back #8 must be flipped to "unlock" the knobs on the top for the following adjustments.

Try turning down the knob on the top left (PLT).
And turn the knob on the top right up a little (PIT).
This will make the helicopter less likely to jump off the ground and act more like a fixed pitch helicopter which I think also makes it easier to learn. Don''t turn up the pitch (PIT) too much because you do want the blades to spin up at a fast rate... too much pitch and the blades, motor, will bog down.

And also it's a good idea to get some rubber bands and secure the switch top right front in the
"N" Normal mode so you don't accidentally flip it to the "1" mode which is 3D (aerobatics mode).

RE: Eagle50
 

Thanks for the tips. I will try what you said. So do you leave the #8 dip on all the time? If the settings you have explained were not set right, would that cause the motor to suddenly rev up and then slow down as it has every time I have tried to trim up the heli

RE: Eagle50
 

I leave the #8 unlocked because I am always fiddling around...

No. the PLT and PIT knobs would not make the heli do as you descibed.

Make sure you turn on the transmitter first........ then plug the battery of the helicopter in. Wait ten seconds before you touch anything else. There have been times when I have replaced the receiver and all of a sudden the helicopter went full throttle.
I can only guess there was a few milliseconds or so that the receiver and the transmitter were confused.

Make sure your throttle is down all the way... and the tab slider for the throttle is also down all the way.

The settings I mentioned above are for dumbing down the helicopter.... so it is less reactive to
the CCPM... which means Collective Cyclic Pitch Movement which is controlled by the PLT knob.
The PLT means Pitch Limit Throttle. As you move the throttle past 50% the pitch, the angle of the blades
also increase. The PLT knob controls that. If you turn down the PLT knob... the blades will not move as much
as you increase the throttle.

I would suggest reading all the messages in this forum and the messages for the Walkera 22e
http://www.rcuniverse.com/forum/m_3722641/tm.htm because your helicopter is the same as the 22E.
You will learn a lot.

And I doubt or don''t know... but it''s probably not a good idea to run your microwave oven or other heavy
transmitting devices near your helicopter while you fire it up.

RE: Eagle50
 

Thank you for all your information robreach, It certainly has cleared up some of my issues. The problem I am still having with the eagle 50 is the sudden surge of power when the throttle is a bit short of half way. As I have said before, this surge is for a split second, but is enough to get the heli airbourne. When this surge happens I am not in the process of adjusting anything, it just happens without warning. I am at the stage now of just forgetting about the eagle 50. I have spent $330.00AU for the heli and some spare parts and still haven't been able to do much more than let it sit in my office collecting dust. As it is at the moment it is dangerous. The company I bought the eagle 50 from has told me it is the esc and they would send me a new one. I haven't received any correspondence as to what they have done to date. I am beginning to think that this product is a lemon and I have blown my money as no-one has tried to remedy the situation. Is this common practice in the rc helicopter industry?

RE: Eagle50
 

From what I know... the "esc" is built into the receiver..... So you would be getting a new receiver.
I have heard that there is a problem with some receivers.
You are dealing with inexpensive electronics. So go figure... ie.... snafu's...
I have two 50's... just so I could beta test them against each other...
I have gotten motors with the wires switched and they spun backwards... and
then switched the wires not switching the diode... and burnt up motors and a receiver
catching fire...
Everything on the "bird" is controlled from the receiver... so you may have a bum receiver.
Hopefully it will work out for you. Obviously... if you drop a new receiver in... then it may
be a loose wire in the transmitter... then it's almost worth buying a second heli that comes
with the transmitter... and another whole bird of spare parts or beta bird.
On more expensive heli's the gyro... the esc.. and the receiver are separate.
Thusly... on the 50's et al... that's a lot of stuff in one tiny little box.

RE: Eagle50
 

I do really find it hard to comprehend that I should buy a spare eagle 50 for spare parts just in case the original one I have purchased does'nt work. I have never come across that way of thinking before. One would assume that when you buy a new product it would be in working order. I fully understand that there will be a need for spare parts along the way, but I think it would be a fair comment to say that my original purchase (of the eagle 50 ) should have been usable for some period of time before replacing parts. The thing is dangerous. All I can say is that I was lucky I was outside when it first occurred. The information you have given me to date has been very much appreciated, but I do think that the companies that sell these products should maybe look at quality control a little closer. What would my rights be if that out of control heli hit someone or something and did damage or injury?

RE: Eagle50
 

Well flying RC is a choice right? That why there are flying fields and AMA license so that insurance are covered in case of accident. All eagle 50 are test fly at the assembly line. I'm sure a surge is not from the power. Have you check the freq and interference. there is a posibility that someone is running the same freq nearby.

The eagle 50 is not a lemon as there are many many happy customers.

Andy

RE: Eagle50
 

Hi Yadac123, Thanks for the reply. At the moment I am only trying to trim my heli. As you would have read, my heli would not have been able to fly because the grub screw on the axis was loose and the main gear was just spinning. I had to order another axis gear from my supplier. They supplied it at no cost to me, which I appreciated. I live on a farm and as far as I could assume there wasn't anything in the near vicinity that could have caused interference. I was very aware of this after the first time it happened. All I am trying to do is get this problem solved so I can enjoy this hobby. I have a Walkera 4 and have learnt a lot with it and buying the eagle 50 was a step to collective pitch.

RE: Eagle50
 

I have just been in touch with the supplier and they are sending me a new receiver. I will keep you posted as to how it goes. Hopefully it will be problem solved.

RE: Eagle50
 

Andy, If it is a frequency problem is it as simple as changing the crystals in the transmitter and receiver?

RE: Eagle50
 

Crystal going bad is very rare. Since you are already getting a new receiver then try receiver first.

Andy

RE: Eagle50
 

Andy, My new receiver arrived yesterday. I put it in the heli last night and tried it this morning. I had the same problem. I took it in to my nearest hobby shop to see what they thought might be the problem. It turns out it is the motor. They put another motor in for me and the heli is now performing the way it should. It has cost me a 1 hour trip to town plus the new motor ($25.00) but at least its working. Thanks for your help along the way.

RE: Eagle50
 

Andy and / or Robbeach, Could you advise me as to what motor to use on the Eagle 50. The original motor that came with it died before I had a chance to fly it and now the replacement motor I put in it has died. I have made sure there is a little play on the motor to the main gear and have heat sinks. Am I doing something wrong or is it just these 370 motors. Any advice would be appreciated.

Chris

RE: Eagle50
 

Forgot to mention that these motor burn outs are not a result of leaving the throttle on after a crash. The problem with the first motor was as described earlier and the second motor just died when I was about 1 foot off the ground (thankfully). The tail motor was the only one working properly. Checked the main motor after I had taken it off the heli and it did not rotate at all, only a burning smell. Also I had removed the yellow stickers. Would the Esky honeybee king 2 370 brushed motor work on the Eagle 50.

RE: Eagle50
 

Usually on the sticker or somewhere is the tag 370 D...
So if you see that it should be ok but I can't promise you.
The pinion gear might be different.. the Bee says 9 teeth..
My motor has 10 teeth. You can get a bad lot of motors...
I usually buy 3 or 5 at a time, and I've some that seemed
not as good than others... mind you I have bought from many
different suppliers.

Try to buy from a different supplier and maybe try a Walkera 22e motor hm-22e-z-17
if you are having bad luck from your guy with those motors.

And just so you know if you haven't read, hovering takes the most energy
except for coming backwards tail in.
You need to let your motors cool off between flights... touch the motors
and you will see if they are hot.

Good luck.

RE: Eagle50
 

Thanks RobBeach, The 2 motors I have were RK-370SD. They both have 9 tooth gears. As I said before the 1st motor didn't even get to hover and the second one had about 3flights ( 3 batteries ).

RE: Eagle50
 

Andy, What is exceeds policy on these faulty motors? Do they replace them for the purchaser, or is it up to us to replace them. What are your suggestions on what replacement motors to use?
Chris

RE: Eagle50
 

Exceed's warranty policy is 30 days.

Andy

RE: Eagle50
 

Andy, I received my eagle 50 on the 31st of March 2008. As you can see form the conversations in this thread the problem with the motors happened before the 30 days warranty. Does this mean that they were still in warranty and if so how do I go about claiming them. My order no. is 344330

RE: Eagle50
 

Alright I'll send you a replacement main motor.

Andy

RE: Eagle50
 

Thankyou Andy, It is great to have a contact system like this. It has been a great help to me with many questions being answered and problems sorted. However, since my last contact the new receiver has died. It is the same channel as the original one (ch. 3 ). I don't know if it is a coincidence or there is something else causing it to happen. I am considering just scrapping the Eagle 50 as I have had it about 1 month and in all about 1 hour flying time. 2 motors, 2 receivers and 1 gear axis have died to date. It has not cost me anything thus far, but I am sure you are sick of reading about my hassles with this heli. Maybe it is time for me to move on. What would you suggest would be a good heli to move on too?
Regards
Chris

RE: Eagle50
 

The main motor on the eagle 50 has a number of xrk-370sh-4928f, while the motor for a elite or honeybee says rk-370sd-4045, i would say the last number is probably rpms , so i would guess there is not enough head speed to create lift. that is the only thing i can figure out.

RE: Eagle50
 

crambell

I would suggest you get into flying foam airplanes.
There are a bunch of us that fly the helicopters that the only problem is
ourselves.
Since you have lots of flying field than fly the planes.

(p.s. I have no affiliation with any company associated in the business)

RE: Eagle50
 

Robbeach

That is a great bit of advice. Do you treat everyone that has problems or questions you don't seem to be able to answer with cheap shots like that? My simple question was what do the more experienced heli flyiers suggest I would buy next as I cannot seem to get the Eagle 50 sorted out. I think that is a simple straight forward question. Your reply was a poor attempt at an answer and not having any affiliation with any companies is understandable as a business person would not talk to potential customers like you have. You said the only problem is ourselves and I agree on that one. My main reason for joining this forum was to get information from people, including yourself, with the same passion as me and there has been a lot of useful information to date. I might reinterate that my passion is helis. You seem to know a fair bit about flying foam airplanes but I am not going to bother to ask for any information of you because I am not interested in your foam airplanes. For your information, my property is densely populated by trees. (pine tree plantation)

RE: Eagle50
 

Thanks Kolls,
I will check out what those numbers mean. You are probably right about not having enough head speed. Would anything have to be changed if I tried the Esky 370 brushed eg. diodes etc.? The reason Iam asking about the Esky motors is that my son has a king 2 and a trex 500. He does not use the king 2 very much anymore. He could send me the motor if it was compatible with the Eagle 50.
Chris

RE: Eagle50
 

that is the question i have been asking i cant find any info on the eagle 50 motor. if the last number is kv/rpm on the rk-370sd-4045 then if you go here http://www.readyheli.com/Online_Head...ator_s/81.html and figure it. the motor should work with the right pinion. i would really like to see someone give us info about the motors. i mean im with you i burnt up 2 motors , i havent crashed it just the motor quits working and with the motor being 11.70 plus almost 10 bucks for shipping. and i have to wait a week to get them. and i just want to go to the lhs and buy a motor.

RE: Eagle50
 

Kolls,
I have been on a lot of forums trying to find out information on motors and haven't come up with anything so far. All I am trying to achieve is to get my Eagle 50 flying and somewhat reliable. It seems that the motors that are supplied have a problem and no-one is really addressing the issue as far as I can see. Andy has been great in sending me a new motor, but will it burn out to? I bought the eagle as a progession to 6 channel helis but haven't been able to achieve much air time. I have also got issues with the receivers it seems. I have now had 2 and they have both died. Channel 3 does'nt seem to be working on either of them. My simple question is was it a coincidence or am I doing something wrong? Now I have been told to go and buy foam planes.

RE: Eagle50
 

Consider installing an in-line fuse for your motor. I've done this on my Eagle 50, HBFP, and on several Lamas. Simply solder in a 5Amp automotive mini blade-type fuse. I bend the metal tabs & clip off the excessive length & just clip the hot wire on the motor & solder in the fuse. It not only protects the motor, but also your 4 in 1.

RE: Eagle50
 

thanks for the tip. As soon as I get a new receiver I will try the fuse. Sounds like a simple remedy for protecting the receiver and motor. What do you think has caused these burnt outs? I am using the supplied lipo 800mah batteries. Could they be to much for the motor and receiver?

RE: Eagle50
 

I dont have an answer for anyones questions unfortunately. I am curious to know what size and type of Brushless motor and ESC combo would work for the Eagle 50. Xheli just souped up their brushless motors and ESC page. Will anything from here work [link]http://www.xheli.com/exrcbrmose.html[/link]

RE: Eagle50
 

yadak123,

Received the 370 motor today. Thankyou very much. Now I am just waiting for the receiver I ordered and hopefully I will be back flying.

Chris

RE: Eagle50
 

Crambell,
I certainly hope the new parts do if for you. I got my eagle about the same time you did, and have had my share of motor problems as well. When I got my third one it was dead out of the box. I am in the process of putting a small outrunner brushless motor in mine. If you like, I will let you know how it turns out. I have got the motor installed with the ESC and so far it looks promising. The ESC mounted above the receiver has fixed the aft CG problem. I just waiting for some smaller pinion gears to get the head speed down closer to the stock speed. Have you had any tail motor problems yet? I'm on my second with a third one in reserve. I did stumble on a neat mod for the tail motor in a magazine. It converts the tail to a direct drive propeller. I have checked and you can get the motor and 2 props for $10 US.

RE: Eagle50
 

hdhg1,
It will be interesting to see how your modifications turn out. I am on my second tail motor. Could you post me a bit more information on the tail motor setup, it sounds like you have all but sorted this heli out. I am still waiting for my receiver. Has yours been any trouble? I have had 2 to date. Second one was dead on arrival. I know what you mean with these motors etc. arriving in the post and not working. I was beginning to think that I was doing something wrong. I am lucky my son is a heli nut as well and he lent me his honeybee king 2. Its been good to get some hover time. I still want to sort this eagle 50 out though as I did enjoy flying it when everything was operational. So far I have only had about an hour of flying time with it. Keep me posted as to how your upgrade goes.

RE: Eagle50
 

i would like to see also if a brushless would work. i only get a few flights out of the heli before the motor burns up. does anybody know if this would work http://www.ehirobo.com/shop/product_...oducts_id=4040.

RE: Eagle50
 

Crambell and Kolls, I'll be happy to keep you guys up to date on my progress. So far the motor I am trying is of the outrunner type. I got it installed O.K. but with a 11 tooth pinion gear, the head speed was way too fast. I have got a 8,9 and 10 tooth pinions coming and one of those should slow it down to a more reasonable speed. I don't know if you guys are interested but have found cnc machined parts for the rotor head. Check out cnchelicopter.com, walkera22e page. Just be for warned, the ball links were a little to large of the eagle links. They bound up so bad that the servos would not center correctly. I removed each ball chucked it up in a drill and sanded about .003" off them. That fixed the problem. Afterwards I have discovered that there are, and I not joking, link stretchers available. These tools are used to reshape the ball link sockets which can get damaged during removal and installation. I don't know if that would work too. It took me about two and half hours to polish all the balls.
Anyway, happy flying, and I'll keep you posted.

RE: Eagle50
 

Kolls, I just checked out your link. That setup is similar to the setup I have put together. The motor I got does have a fan attached which hopefully will help in cooling. Be advised though, you will need to build a harness to connect the battery, receiver and ESC together. The connectors are readily available so that should not be a problem.

RE: Eagle50
 

Hey Guys,
Forget what I said about the cnchelicopter.com head parts. They are JUNK! At first I thought my head shake problem was cause by a bend main shaft. I just replaced it and I still had the problem. Upon further investigation, I discovered that the teter toter does not have bearings in it. It is just pined. I replaced it with the stock part and am still having problems. diging a little deeper I have also discovered that the main hub and blade grips are of low quality. One side is not seated as far in as the other and when trying to adjust it, i have found that it binds if the screw is tightened to much. The stock part did not do that. Anyway, I going to see if I can get my money back on these parts.

Sorry for the bad info, just goes to prove, looks aren't everything.
