Hmm. Let see....

25v x 5Ah = 125Wh

$ to charge = 125wh x $0.11/1000wh = $0.014

So, charging 100 packs should set you back whopping $1.40. :O
LOL, that's hilarious!
Hey you keep that BS in the off topics thread. This is the BS free thread.
That's funny too!
as to which is better depends on the guy doing the flying
Come on CX, I know you like the E's...don't try to deny it, I've seen some of your other posts...

Six of one and half a dozen of the other. The Nitros fly half again as long and don't take an hour to charge. Whatever I'm doing, I don't get 300 flights out of a pack, and am lucky to get 100 good flights. I've puffed a pack on the first flight and had another that was bad new from the package. The electrics aren't any more reliable than the nitros either, with burnt ESC's, blown motors, toasted bearings,and melted connectors. So far, the electrics have cost me more to fly when I total everything - chargers, batteries, motors, ESCs, crashes from electrical failures, etc. The electrics are also significantly heavier - almost a pound more for the 700 and autorotation performance is significantly worse. Yes, you can make a light 600 stretched heli, but 700mm blades on a 600 size head is just scary. The electrics are smoother, quieter, and cleaner. When I fly electric behind the house, the neighbors don't even know I'm there unless they happen to look out their window in my direction. It's all fun and I like them both. steve.

That is probably one of the main reasons I do not fly electric for any size >= 50 at this moment.

I will place my 2 cents. I have come back into the hobby after becoming a father. I can say this if you have the time and money E-helis aren't bad. But I can say for a newbie and not having people to call. It can get confusing. With all the motor choices,esc's chargers and batteries out there it can get confused. Nitro isn't that hard find a motor,the correct. Governor and your set. For examplethe outrage 50s site gives you an ideal set-up for beginner to 3d flying....so I will say either or are great....its just all about your learning curve.

you haven't been treating your equipment properly have you?

I'm going electric and will have no burnt ESCs or toasted bearings or melted connectors, and if you pay for the better quality stuff you'll get very little problems as long as you treat them right.

I travel a good deal and spend time on fairly long term projects around the world, and the electrics make it so much more convenient for this.

I noticed that most of those in the "ONE" competition at this years IRCHA used electrics.

Some electrics are pushing 15 Hp, that usually works out to about 1 Hp per Lb.

I think about the hereafter. I go somewhere to get something, then wonder what I'm here after ?

LOL I love how people guestimate the HP output of an electric motor

it's not what the motor consumes that determines HP.
it takes a dynamometer to determine HP and torque
anything else is just theory

I think if you could dyno test power and torque out both E and N would be surprised.

Till then...let the ignorance continue

I've not yet heard of peaks of 15 yet, but I seen peaks of over 10,000W through the data logger. But again this is what the ESC sees and only for a very short time, else the main gear would melt(and so would the motor)! If one knows the eff. of the motor, ave. and peak temps of the ESC(if it barely heats up for instance), than a close approx. should be able to be determined. But again these are peaks, maybe a better representation of watts needed to do a certain routine would be the average wattage the ESC sees for the entire flight...multiplied by the motor eff.
Anyway, it's only on the most taxing maneuvers(at the same HS) will the electric out shine the standard glow. When the glow reaches it's power threshold, the electric will continue to pull through because of their peak power qualities.

The motor in question was a Neu motor, I've broken a couple of Align motor shafts as well. The ESCs were Align and Castle, the connectors were Dean's. All known and widely used brands. Maybe you will never have a failure. Maybe I'll find a gold brick under my bed some day. I hope so.
CX1 is right that power consumption is not horsepower and some of the claims I read seem extraordinary. HP is measured on a dyno, not a datalogger. I would agree that the electrics I've seen have more torque than any nitro motor. steve.

Like I said in my previous post, I don't think 10,000 watts on the data logger equals 15 HP in real life. The motor is not 100% efficient and the peak current doesn't equate with what the motor will do steady state. I'm thinking the peak is similar to a flash reading on the dyno for an internal combustion motor which can be up to double what the steady state reading will be minus whatever the efficiency of the motor might be. I've seen you all's helis fly and there's no 90 size motor ever made that can equal them. The cost is in flight time and weight. I like to do a lot of autos and I can't do them nearly as well with the electric as I can with the nitro 700 although I've been playing with the electric Predator lately using 710 and 720 blades. The disc loading is getting close and the 12 cell/720mm blade combo works better than the 10 cell/690mm combo did with similar or maybe a little better flight times. Looks like a good day to fly, hope you get a chance to get out and do some. steve.

steve,

I'm only going to run YGE or Jive ESC. I'm only going to run either scopion or pyro motors. I won't touch Align or CC, that's the end of that.

battery-wise I heard that the new optipower batteries are quite good. If you get 300 cycles you've more than had your money's worth.

Don't do this with your e-heli !!
Doh!! I ran my N heli till the tank went dry
I was to enthrawled with the noise and smoke to notice the fuel level
had it been my protos I would have lost my lipo (case of fuel)

I was lucky enough to get away with a small ding on the tail boom

Well,, I dont know how many horse power my motor is putting out on my 700E its a stock 700MX. I can tell you though my YS SR 3DS doesnt even compare to my electric. I found it boring to fly after flying my electric so I sold it along with all my other nitro helis. I cant even imagine what the HK3 motor with some TP65C's is going to be like when I get my hands on some.

I do miss the longer flight times, but not the mess of nitro oil all over my helis. I think batteries will improve and flight times will go up, making electric unargueably better than nitro in every way.

Re: watts &.horsepower
There is a conversion for this. See the link below. For example 10,000 watts = 13.4 horsepower.

That is for a second
That 10000 watts is actually 4500 continuous MAX. So cut that HP by 60 percent.
