Agreed. But if you are ever able to fly a powerful 90N, and then fly a powerful 90E, both set up properly, and are able to fly well enough to take advantage of the power of both...you will then know for certain what I am talking about, all theory aside.

There must be a form of psychosis involved with the decision to switch to E-power, because as soon a some one does, they instantly feel the need to convert those around them. Now, YS is making grounds on improving power with what should be a lighter overall package, and the E-crowd is out to denegrate their efforts to do so.

Many people simply don't like to charge large lipo batteries. I flew to an international F3A competition on the same flight as an E-pilot that carried several 10S 5300 packs into their luggage and was very nervous about the possibility of those packs creating an inflight emergency. All it would take is some form of luggage misshandling to potentially arc the packs.

I'd rather hear glow engine sound in the air than generator sound drowing out the pits. If you field has 120 power, its a lot easeir to fly electric. For my time at the field, I prefer to fuel, fly, clean, rather than fly, charge, go home, watch batteries charge for hours.

The RESULT and PROCESS are equally important to many pilots. Pros and cons eitther way. I just don't see the reason for all the E-pilots to down grade glow machines. If you want to fly E - have at it!! But understand, that some of us don't want the charging process of E-power and such.
Thanks,

Does anybody really know what hp these small electric motors are rated at?

If you look at the latest Scorpion 4525 motor, it is rated at a continuous 4300 watts.

4300 watts /746 = 5.76HP. That's probably a pretty accurate statement of continuous power. Peak HP is probably twice that, but as the above statements mention, that's not really an accurate measure.

I was wondering if any of the manufacturers ever listed a hp.

+1 to Jim.

Some of the posts on here about Nitro almost sound like some of the "E" people are hoping and praying that nitro goes away.

I really don't understand the mindset behind that

Gee, Talk about a thread going off track !

Can we get back to what i clicked on this thread for

INFO ABOUT THE YS 120 please.

I am testing the KME 110 and can tell you the torque the motor produces is well and above a 90 either os or ys for that fact.

Im sure if YS have the same pump regulator combo that they use on all there motors so far this thing will be a hit !

Bring it on baby...

Well I am trying to believe that these motors could move 6000 lbs a foot in a second with any gearing, thats hard to fathom.

Yea, I don't understand all the negative conversation about something that has not even been brought to market yet. I have flow nothing but nitro for the past 4+ years and recently purchased a Furion 6 electric heli. Absolutely a great heli but I don't like to fly it that much only because I HATE charging packs.

I also don't understand why there is all this comparing of nitro vs electric. Fly what you want! If it's electric, than fly electric! If it's nitro fly nitro. If both, so be it! What's the problem????

The way I look at it, electric had to catch up to nitro and now nitro is fighting back. That's a good thing for the hobby! It makes both power systems compete with each other and we as the end user wins!

Come on guys, thank god for companies like YS! They make an amazing product and are always improving it, what more can we ask for?

Good pointt Sam,
Looks like some folks find it pointless to produce a larger glow engine, and think we should all go out and buy carbon credits from Al Gore. (yes is a joke, eat your pop corn guys)

The fact is, there are plenty of modelers who still prefer and enjoy glow engines, and they are the ones who hopefully will enjoy this product.
I love glow and its smoke, but a well tuned 90 is my limit. Most folks don't know or really tasted one.
I know AaronJ has

On the other hand, no one can deny the advance in electrics, batteries, and their "particular" advantages. I now have a primary competition heli electrified, and boy is it better! That is a specific application. If I am going to blast around for some good ol redneck flying I bring a 2 stroke and a jug or two of my favorite glow juice.

2-stroke glow engines SUCK at being efficient, we know that, and we don't care! When you look at how simple this engines still are, is amazing how well they do.

Ben hit a very important point on his 1st post when he said, smooth running engine. Any engine can be a stump puller, but if it kicks like a bucking bronco @ best HP, it is useless. The power must be manegeable. We have enough 4 stroke technology to make absolute HP monsters with MUCH BETTER EFFICIENCY. BUT, the tortional vibration from a single cylinder engine 4-stoke is insane, and hard to manage in a simple helicopter frame. There are ways, but all solutions cost more money. The engine wont be cheap either!

By the way, you only need RPM and a torque measurement to calulate BHP.
If you measure fuel flow, you now have "specific fuel compsumption" which is a measure of how much power the engine makes per unit of fuel.

NOW:
Could we see videos or picture of the new YS? I am out of popcorn.

+3 for a video.

I can understand why many electric guys tend to "psycho" nitro guys into electric.The first time I flew my 10s electric, it pulled so much stronger than my 90size at its optimum condition(new bearing, 30% nitro, needle adjusted for max power). It was just insane...I never had that sort of feeling even when I moved from a 50size to a 90size. And for the first time, I didn't have to dirty my hands.

However, nitro heli still has that something that electric doesn't. Perhaps it is the sound and smoke. I will love to be able to squeeze a 120 into my 700n, if it is practical enough.

As a weekend flyer, I honestly don't care about what technology goes behind it. All I care about is just the power, cost and practicality.
If it is really expensive, requires a even more expensive hatori to match and drink 50% more than a 90size, I will not be able to afford it. If it requires a even more powerful and expensive starter to start it, I might reconsider. I don't mind changing bearings every 60-80flights, but definitely not more frequent than that.

Ok so back to the original meaning of this post. Any videos yet proof is in the pudding let's see how it performs, it has to be broke in by now??

...Once upon a time there were Nitros, flybars and frequency pins...
Last Sattuday, he flew the YS monster with new design pipe at Carson field, It got the power of 700e, I never see any 90 nitro can compare to it. , Finless got the videos, I believer he will post soon on Freak forum.
