Hi everyone,
On the FJ 2006 thread there's talk of BVM's EDF. I can't figure out why he would go back to DF. I can see why guys buy the foamies that Hobby Lobby sell; they're relatively cheap, and you can fly them in a small area.
The pictures show a regular size model and BV model's are anything but cheap. I'm not sure who the market is, especially with all the known limitations of DF. I'm guessing you'll still have the DF noise and you'll need a regular size field to fly them, so why take the step backwards to DF?
BRG,
Jon

There's probably a bigger market for EDF than turbine.

You don't need an EDF waiver, you aren't limited to 200 mph, etc., etc... so maybe something like this appeals to a sufficient number of people to make it worth BV's while..

Very noisy, why - you can hardly hear the backround conversation

Actually, it is the FAA that limits to 200MPH, not the AMA, so you would still be limited. Not that the FAA pays any attention. Bob

MUCH bigger, I would say. Much.

Jon, sooner or later you will have an electric epiphany and understand.
Electric will soon outperform glow on all fronts.
It already does on the smaller ones.
EDF is a totally different animal from turbine, you can fly it in places where turbines are unwelcome, they are much less intimidating to civillians and such.

EDF is easier to set up as a plug and play system. I have not flown glow ducted fan for 9 years just electric. I'm not looking back either. BVM would not be doing it unless there is a market for it. And there is!!!!
Bob

Yup. I liken the recent progress to Moore's Law, where the power of computers doubles and the price drops by half every two years. Same thing is happening with electrics!

yea, elect's have that cooool sound and the smell of jet-a- .......ooops i mean burning lipos and remember a good plug and play elect for a viper size bird to perform will be well over $1000.00for power pkg. and start multipling when you start burning batts.-if silent jet flight is the next big thing you all have already missed the bandwagon -it's called sloap soaring! sorry, i don't see the point of jet elects through my closed mind unless they are inexpesive foamies, not what a bv airframe will cost and i've flown bvm exclusivly for 13 years[:@]

Well...maybe BV knows something you don't!

just remember he spends lots of time and $in the engineering and it will be first class , but the electric mentality out there for the most part will probably have sticker shock and will not be able to justify compared to what the current foamie standard has been. turbine flying has been all about the sound and smell to give you that warm and fuzzy feeling of realism and that isn't going to happen w/lipo and how many cars will burn-up as the newbies learn to care and feed their new highly volatile technology. --signed the devils advocate[:@]

My cost for a scale EDF (90 mm) is around $1000 to $1200 today. If I could get a BVM electric for $1500 I would. There are alot of 90mm stuff out there and it is growing. Batteries will last if you take care of them. Not everyone who flies electric flies parkfliers.
Bob

Not sure what reg what that would be Bob. Maybe you know something I don't. That would mean model rockets break FAR's all the time. As you should know, if we were busting an FAR the FAA would care. I always understood the limit is based on AMA insurance requirements. More important, where's the flight report on that F-16? Bob

was not being pregidous only making a general statement. the tech. is impressive but will the masses pay for it. you high tech elect guys are a small cottage industry compared to the foamies

Are you serious, in that you have never owned ANY jet but BVM? Wow.

This technology has absolutley nothing to do with some park flyer foamies...we are talking ten to twenty pounds of thrust, and climbing, from some very serious motors.
You'll see...it's changing fast.

Jets in general are only a tiny cottage industry compared to prop planes.

Things are really changing, and FAST. It's not really "high tech" anymore for prop stuff...if you want to fly a 40 sized plane, you can fit it out with pretty much all off-the-shelf stuff and not a lot of guesswork and not a lot of money. The planes are getting bigger and cheaper. I'm not talking park flyer stuff here, I am talking about a revolution in the larger stuff.

thrust is currently going for approx $100.00 per pound w/ turbies will elects be 1/2 that since they will only be 1/2 realistic. i guess if i buy one of those fancy futuba radios i can have a turbine soundtrack playing and a elect jet then can be what we already have THE REAL THING!

Masses aren't required, just a small portion. What is the total # of waiver holders? 1,000? 1,500? How many of them fly BVM stuff? A lot but not all. SOME of those guys who like the idea of a "fast enugh" jet they can fly at the local model airport will buy it. Convince a small percentage amongst the 200,000 or whatever the # is other AMA members who DON'T hold waivers and thats called a MARKET.

$ and cents look at what the avg. club flyer flys and compare that cost to any decent jet kit out there ie skymaster

"Realistic?" A Viper does not even have a CANOPY. To me, there is nothing very realistic about it, it looks like a toy jet, nothing like a real one. Same with a BobCat or KingCat or most other models.
On the SCALE side of things, though...hey...turbine has electric whipped. No doubt. The sound, the smell, yup, that's a missing part of the electric package.

I think a LOT of people would never touch a turbine...too intimidating, or they don't have a place to fly that will allow it...and would definitely spend the money on a serious EDF jet. I guess we will see.

Skymaster? Thought you only did BVM?

Cost keeps dropping on the electric stuff. Just bought batch of motors that cost about a THIRD of what they did a year ago. No exaggeration. Same with the batteries and ESCs.

And...like I said before...with the smaller stuff, the electrics already EASILY outperform glow.

that was using sky m as an example of a good moderatly priced -quality kit

If BVM utilizes their glow fan unit for their electric version all of those BVM fan units that you could buy dirt cheap will have renewed value.....I would imagine all that would be needed to convert a glow unit to electric would be to swap out the engine mount/faring.......And maybe an adapter for the rotor........

Kevin

You'll see. Your convictions about what electrics are all about, what they can do, what they cost, etc...that will all change. I know mine sure did.
I did electrics right from the start, going back to Astro Ferrite motors back in the Seventies. Got out of it a long time ago when I wanted "real" performance. Got back into it only pretty recently, when they started HAVING "real" performance!
