ELECTRIC BERGEN

[BobbySmith]

Alot foyou guys know me i fly alot of Emachines and i was wanting to know the interest of maybe doing a E bergen.I t would be based around the New Magnum

There are those days when the Nitrodoesnt want to act right so you throw back in the truck and yank out the Electric :lol:

post youre thoughts

Batteries are too expensive. And they're for people who can't tune an engine right. :mrgreen: (Just kidding)

Nitro RULES! :glasses:

I think EVERY manufacturer should offer something "E"

I think the expense of the batteries may be the biggest hurdle Bergen has to overcome, if they are to be successful.

If they would consider reviving their 46/50 size machine as an E-heli, it might be the best of both worlds. Excellent power-to-weight ratio and not as expensive to put in the air as a 90.

Since the lower frames (and everything between them) is usually the only part that changes from one model to the next, I don't think it would be a huge stretch for them to make a lower frameset that can mount an electric motor. If that was available as a conversion kit, anyone could convert any Intrepid to electric power.

Just thinking out loud here... All that would really be necessary is lower frames, motor mount, pinion, and radio tray. The frames could be set much narrower than than the gasser to mount the batteries on each side of the bird in a saddlebag configuration. That would also help to balance out the bird.

How is it that Bergen has to overcome the price of batteries? Bergen R/C doesn't make batteries.

The thing is wiht the new battery Technology we are using the same 10s1p packs to fly 90 size electrics as you would use in a 50 size electric
You are looking @ roughly 900.00 for a power system w/ batteries i have spent almost 800. on cspec motors wiht OMI mods and sb 17

here is ssome 50 size power http://www.helifreak.com/viewtopic.php?t=14068

and here is some 90 size power same batteries http://www.helifreak.com/viewtopic.php?t=10894&sid=cd4e5a6e999204606a9b48eb751d6297

And you ar right it would be reall easy to get 32-3 Actro motor in that thing

[Greg Alderman]

Paul...as you sort of mentioned...any Intrepid could be converted...I would think you could easily decide on what size bird you wanted when building and buying the motor...short tailboom, 600mm blades...you have your self a 50 size electric...33" tail boom, 700mm blades, bigger motor and batteries...you have yourself a 90 size electric! I would think the lower frames and powertrain would be the same on both sizes...Best of both worlds...

I would like one myself...been wanting to try an electric that was bigger than a TRex...but didn't like my choices for airframes...I would for sure buy one or convert one of my Intrepids I have now to electric if this becomes a reality...Even here in the DC area I have fields I could fly an electric in that I wouldn't dare fly my turbine/nitro or gasser at...

I personally would probably build it up as a 50 size because of the battery expense...but I think a lot of people would like the fact you could build either size depending on your budget

If there is any doubt, take a look at the Ion-X vids of my Ion flying. B is the #1 source of help I have needed to make my E-helis fly the best they can.

I will be in line for the first few Bergen E Magnum's that are tested because I want one and I know the potential of the machine. If you have any doubt now, jsut wait until B has his DC way with a Magnum and you see us flying ours at the events. :) I know I will be behind Bergen Reps, Greg/Mal/Chris/B but I am definitely interested, I will move out whatever I need to pay for it.

I am with you B!! Lets do it!!

Because if people think the batteries are too expensive, then they won't bother buying the airframe. Bergen is not the cause of the problem, but their sales would be affected by it.

Maybe a 10s2p e-moli setup? That would take three Milwaukee packs and leave you with one cell left over.

[SeaHawk]

I have really been seriously considering an electric bird. If Bergen came out with one, I would buy one. Great customer service and nice people to boot.

[ShawnK]

Paul,

Agreed. My point is, it's not accurate to say battery price is an "obstacle" for Bergen to overcome.

Semantics, perhaps, but the way I read the original post, it sounded like it was being suggested that if Bergen doesn't get the price of batteries down, they wouldn't be able to sell anything. My only point is that Bergen is not responsible for the astronomical price of batteries.

I still think battery technology and price has a ways to come before it becomes a truly popular and viable alternative to glow power. Just one man's opinion...

[PaulH]

Picky Picky :roll: :lol:

[ShawnK]

Yeah, I'm finicky like that. It's a shortcoming. :mrgreen:

[ShawnK]

Well, I hate to do it, but recent unemployment and an ever-tightening household budget have forced me into selling one of my machines.

Bergen Intrepid 50 for sale... check here (http://www.helifreak.com/viewtopic.php?p=115180#115180) for details.

[BobbySmith]

Buddy sorry to hear that this time of year it is tuff my Bussiness has been off as well. Nice looking 50

Paul the Emolis are pretty neat but you can not get the power out of them like you can Lipos I personally think 400.00 for a set of 20c lipos is cheap shoot a year ago we were paying 800.00 a set

Any ways i fly Nitro and E power i thinkit would be awesome to have one machine that did both.

[Malorie]

I've told Bobby this already, I'd be willing to work on an e-Conversion (frame layout and engineering bits). I'm sure we could get something worked out.

The difficulty that I see with a 50 intrepid as an e-Heli is that the entire control system and drive train is the same as the Magnum. That makes for a heavy expensive 50 sized e-Heli, but a VERY solid one. Not sure if that would be the way to go, but I'm not very well versed in the ways of those mysterious electron eaters. ;)

We can certainly do some CAD layouts and see how it progresses. :)

[Malorie]

BTW, Shawns Intrepid 50 is a REAL nice machine. It has been well cared for even if it was beaten to death by it's previous owner. ;) It has had pleanty of TLC since it changed hands.

[BobbySmith]

Haha i would go wiht the 90 size.

It would be cool to have the same mechanics in Nitro form and E form i got to get my 2nd Magnum then i will get wiht you on puitting a E machine together maybe we could have something flying by Ircha

[ShawnK]

And for those of you who were wondering, Malorie was the former owner. :mrgreen:

[Malorie]

I could see keeping the uppers completely intact and just working out a reasonable redesign of the lowers.

[BobbySmith]

Yup i was thinking same thing.
Plus the Epower has less vibration basically make the lower frames to hold batteries aslo could shorten the battery tray for weight and maybe we could get a custom super light magnum canopy :glasses2:

Basically what i need to do is send Malorie the motor and she could lay it out

[epc2]

Electric-EB with an Actro 40 Powerjazz 63v and 14s yeaaahhhhhh baby!!!!!!!! :glasses:

epc2.

[BobbySmith]

Now Epc2 that could be wild!!

[sky high]

I think EVERY manufacturer should offer something "E"
Yeah, as long as it's a turbine and still produces that Kero smell, ahhhhhhh. :mrgreen:

[epc2]

Now Epc2 that could be wild!!

The good thing about an e conversion of the EB is that you can get rid of 1lb of ballast with the batteries in the front we can use the packs that we use on the ION in 15s1p 3700 config (3 5s1p in series ). a Powerjazz and an Actro 40.

I'm going to fly mine with the G26 for a while but , I was really thinking on that for a future project, if the Magnum and the EB have the same lower frames that means that the same mount will work on the EB.

Or a NEU BAM ( Big ASS Motor ) :roll: , that motor is being used in 25lbs 35% 3d & IMAC planes!!!

epc2.
