Dont Charge get a generator

[aileron bail]

fly all day it keeps battery at 5.1v it will charge a dead 4.4 battery its a axi out runner motor :idea: it will fly 3D with the switch off no battery

[WillJames]

:idea:

Interesting!! Thanks for sharing!

How do you start the heli with the start shaft being used? Most of the gassers I have seen lately don't use the pull start system anymore. They prefer to drop the weight and just use a starter to start the engine via the start shaft.

One of reasons people get gassers is so they dont have to take a flight box . When i go to fly i take a TX , Camping fuel and thats it !!! As for the pull start its removeable. 5 pulls and its running and charging, if you use a starter you gotta charge it too. I think your missing the point here I dont have to charge my heli :lol: Do you ? :mrgreen:

[WillJames]

Man that is such an alien concept, not having to charge a heli. :shock: :idea:

Is it reliable, how long have you had this setup installed?

[aileron bail]

I know a guy that builds them and he has over 100 flites :glasses2:

[DavidH]

What makes the above generator cost nearly twice as much as the Sullivan one that has been in production for several years?

I know Bergen installed the Sullivan unit on one of his gassers a couple of years ago?

yeh I been meanin to ask Larry just that same question.

Mal has a sullivan in her observer, in fact I can prob call them today. I'll holla back and let ya'll know what Bergen says

[aileron bail]

The out runner motor is a axi and they are $75.00 alone and then the voltage regulater is $45.00 and then the board and the mounting hardware for the top start and so on. This is 4oz complete the sullivan without acc. 5.5oz and plus the sullivan was made for airplanes.It has exposed mag sensers where we dont have them. The one i have is for a helis and plus its rock solid and much cleaner installation where the sullivan cant compete.It can be made to your specs. Plus if the sullivan was any good you would see alot more of them (tell you the truth i never seen anybody use one) :glasses2:

Seeing a lot of a product has nothing to do with the quality. How many of the generators like above are in use. This is the first post I have seen about any generator, so there is very few in use. Does that mean that this one is not quality. I don't think so. Just a fad like a lot of things are.

David

[aileron bail]

The sullivan has been out for several years and the i have maybe 4 months and it is made by a hobbist like yourself. He dont advertise his product... sullivan trys and we all know the results.. I still dont know anybody that has one .This is a whole different system,easy to install (15min)and bullet proof and for helis not airplanes but anything can be modified :roll:

[DavidH]

My opinion. With the battery technology we have today I see no reason to use an on board charging system. With aerial photography there might be an application where it could be used to power the camera system.

With Li-Ion and Li-Po cells it is possible to have high capacity batteries that weigh very little. Using a regulator the current and voltage to the system stays the same from the first flight till the last flight. The batteries I use provide more than enough power to fly 12 flights of about 15 mins each. That is 3 hours of flying time, that is a long time to fly that much in one day.

All the products are pretty much made by hobbyist. That is how they get introduced, is hobbyist will come up with an idea and then it is made. Only difference being the manufactuers have the ability to produce larger quanities more quickly.

As for the Sullivan product, I believe Malorie has one on her Bergen Observer. Does that make it a good or bad product. I don't think so. She was just innovative and put it on the heli.
The only application I can see the generator you have being used is on a gasoline power heli that is able to be pull started. I would think that is a very small minority of the heli community.

No... theres one on a Raptor and its belted to the main but your still missing the point . I dont have to charge batterys anymore or worrie about burning the house down with lipos and thats a big bonus in this game. i read in your post your having issues with your duralites? that was a joke :D

[blakka_1]

No charging needed?!

Nice 1. :thumbup:

[Garland]

I talked with Larry Bergen and he said the Malorie/Genesys was a experiment that they got to work. For it they put magnets in the clutch bell and had to do alot of rigging.

Bergen has seen the Rbort posts and recommends the outrunner on the start shaft setup over the Genysis due to installation ease. They both give about the same performance.

Yeh for my Money its Rbort to the rescue!

[DavidH]

I don't have to worry about burning the house down with Li-Po's either. I have never used Li-Po's. My battery system is fairly simple, I fly all day and then charge at home.
I am not against some one designing a generator. I just like to keep things as simple as possible.
Murphy's Law comes into play too much with helicopters.

:arggg: Never mind lol :lol:

Hey guys:

Yes this generator is a great system. Actually its much more powerful than the stock genesys system which is 800mah output. With this unit you can pull 5+ amps -- I think the motor can handle even more but the regulator is limited to 3 amps continuous 5 amps burst for 5 minutes otherwise it will overheat.

The best thing about this system is that you DON'T have to charge. I am going to Maine this weekend for the holidays and the heli goes in the trunk when I leave, and stays there for the entire trip. I just pull it out wherever I find a field or club to fly and I never have to do that "embarassing" walk into the hotel room with it at night so I can charge it in the hotel room while I sleep. A couple of weeks back I went to Montreal for the weekend and did just that.

Nowadays I just charge my TX when I need it (every about 12 to 15 flights and before I go on a trip) and top off my heli at that time. Great little system and well worth it. I had my doubts about "keeping it simple" but once I put it on I decided I should have done it alot sooner. Now I don't like to fly without it. It gives that relaxing feeling of no battery worries when I fly, kind of the same feeling you get when you fly with a neckstrap instead of without (no fear of dropping the TX in flight). Maybe you guys never got that feeling, but some of you might have and will know exactly what I mean.

Anyway, yes I am making them for people and selling them for $200. See them at : http://www.massheli.com/gallery/raja

I am in the process of making 6 units right now, 4 are sold, as of now two are still available. Let me know if you want one of these from the current production run.

Raja,
Can you run this system at 6v?
Also can you run the generator into on of the new Fromeco regulators?

[aileron bail]

Yes ...it has a voltage regulater so it can be regulated to your specs i dont know about Fromeco. Raja should get back to ya after the holidays or PM him

[rbort]

Sure I can set you up with a 6v regulator if you like. The reason I chose 5.4 volt is that the 4 cell battery pack I am using would be just about fully charged at 5.4v and I wanted to shut off the charge to it before it started overcharging it. Also, 6v is not as nice on electronics and some gyros are sensitive to too much voltage and are labeled 4 cell pack only. At 5.4 volt its like using a fully charged 4 cell pack all the time.

If you want 6v I can get you 6v but then are you going to use a 5 cell pack with it? With a 4 cell it will be too much voltage and you will overcharge the pack -- not good. With a 5 cell pack it will be too low of a voltage and it will not charge the pack, just slow down its discharge while you fly. Not to mention it could damage your sensitive electronics (gyro) or wear them out sooner in general (higher voltage).

Personally I see no benefit to 6v over 5.4v, but some people like it for increased servo speed. Let me know if you want a 6 volter and we can arrange that.

NO you cannot use the Fromeco regulator with the generator. It will burn out as its not rated for over 10 volts. The generator is capable of 5 volts at idle to about 20 volts at full tilt rotor rpms (I get around 16v at 1740 rpms, but depending on people's gear ratios and some people running 1900 rpms, I wouldn't be surprised if at that speed you got 20v out of it).

The regulator that I use is rated up to 35v input, so it can easily handle the voltage range from the motor. Also it is a switching regulator so it doesn't waste energy all in heat. The Fromeco looks like a big heat sink and that think will be on fire at 20v input.

-=>Raja.

[fitenfyr]

Raja,

Ok I am confused?

The reason I want to use the Arizona is because it is a dual output regulator that will give 6v to the servos and 5v to the gyro and tail servo.
No electronics burnt out here.

NO you cannot use the Fromeco regulator with the generator. It will burn out as its not rated for over 10 volts. The generator is capable of 5 volts at idle to about 20 volts at full tilt rotor rpms (I get around 16v at 1740 rpms, but depending on people's gear ratios and some people running 1900 rpms, I wouldn't be surprised if at that speed you got 20v out of it).


Where you looking at the specs for the Arizona heli regulator?
From what I see here...
http://www.fromeco.org/Shop/aArizona%20reg.htm
Looks like it is rated to handle 20watts to me (with airflow).

What you are using looks like nothing more than a Koolflight UBEC that is why I asked if it would work.

If you say this generator puts out 20 watts at full power I will ask Mike and Kurt if it will handle that.
I like my 6v setup, but I would like to use a generator on the AP gasser.

[rbort]

My dear fitenfyr:

LOOK at the input voltage for the Arizona regulator. Right there on the link you sent me it says 6 to 8.4vdc. I searched for it on google on it before and found another listing that showed input voltage up to 10vdc.

Go ahead and call them but I would bet if you feed it 15 to 20v input voltage its going to overheat and toast. Maybe you need a bigger heat sink for it, or a fan to cool it. I just don't think it will handle that much voltage the way it is stock.

You can always use two BECs one 6v and one 5v or regulate some part of the 6v to 5v depending on the total load needed.

This motor can give you 50 watt easily so the Arizona at 17watt isn't going to cut it. I already called them once to inquire about the input voltage limits if I remember right and chalked that one off as a "no go" when deciding on which regulator to use.

[fitenfyr]

My dear Raja.....

Well after that wonderful response from you I have ZERO interest in purchasing anything from you.

I made a mistake and boy you sure rubbed that in didn't you.

I WILL call Mike and talk to him. :D

[aileron bail]

Mr ftenfyr..... from what i read here its sounds like alot of good info.I think your wrong if you think RAJA as you put it "rubbed it in" hes a very nice man and full of information i just think you read his responce wrong.He gave you all the info you asked for and more.If your feelings got hurt i am sure that was not his intention.
