dead of Zenoah ?

[Rumore]

I was planning to convert my old 90HZ to gas because I need more power and less weight than a Zenoah but now I will wait for the new OS heli gas engine.
that means for me a premature dead of zenoah stuff and no success for the new whiplash gasser...GO OS!

Hmm.... A 15cc gas motor modified from a nitro crankcase vs a 26cc designed to run gas motor...

15cc vs 26cc or even a 29cc..almost double...

Yep your right, Zenoah's are dead.

The carb in the photo is a nitro engine carb, isn't it? Looks hype to me.

Along time ago we hear about this micro petrol engines but until now we didn't see anything.Besides i believe this thing it's not going to have the power of a zenoah engine.

Hard to see how it could at 15cc, though, perhaps a tuned pipe could make up the difference (if they produce one).

Maybe they want you to run a petrol nitromethane mix? (assuming they actually mix).

what's the problem with a nitro crankcase ?
it's just the 1st prototype and OS already has airplane gas engines so they aren't newbies in this matter, they know what needle bearings are!
they firstly have to test it, if the power is not enough they will maybe try it with the 105 size engine.
you won't get the 3.5 HP of the .91 glow engine but it's half the weight of a Zenoah

have you ever run a glow engine converted to gas ? I doubt it you are just trolling.

Nah. That's an Align paper weight from their defunct foray into the gasser world.

It is also half the displacement. So about half the power.

From the sound of this engine i don't believe it's gas.I believe it's a standard nitro engine.

Yes, OS.50 converted to gas = "benzina verde" = green gas = 95 RON http://en.wikipedia.org/wiki/Octane_rating

No success to Whiplash Gasser? Are you serious?! Ha! That model (the WG) has got me more excited than when I was 6 years old and waiting for my Red-Ryder BB Gun!

[Azalin]

OMG it sounds terrible.

[Seasick78]

MA Whiplash Gasser killer?

That's all you buddy! I'll stick with MA.

I know HPI is working on a new gas motor for rc trucks. I'm not sure about the release date. Or the specs even. Supposedly it's a purpose built design.
My guess is that a purpose built motor would perform better than a motor designed for something else then converted for use in rc. Sorta like race engines. Similar engineering but made to make power in specific ways for an exact purpose.
The pictured motor may be pure hype, but I hope it's a direction the manufactures go. The first one to make one with power and weight to challenge nitro will get more than a few sales. Maybe it's not possible. But then again humans said flight was impossible at one time.
Im glad that I got into this hobby. Lots of innovation.

It looks to me like it'd drop right into the Whip nitro frame so I think Whiplash will live either way. Like everyone else I'm curious to see what this engine is. Is it ment to be a leap forward in 3D performance? Or is it aimed at the sport flyer crowd? If it's for the sport flyers I think it'll be hard to compete with the Zenoahs. The Zenoahs have plenty of power for sport flying even in stock form. They're reliable, have a pull starter (or pull start option), they're heavy but for cruising around on a windy day that could be a plus, and in stock form they're much less expencive that the current 90-120 slimer motors.

Maybe the engineers at OS have found some magical way to burn gas without the weight penalties of the weed whacker type engines. I hope they have, but I kinda doubt it. We'll have to wait and see what it is when it hits the shelves. I will buy one just to find out. Heck I'd stuff it into a 500 if it won't 3D the bigger stuff.

Personally I think the most exciting part of the OS engine announcement is just the fact that gasoline helicopters have drawn enough interest that a major r/c engine manufacturer is investing time and money into our little niche within a niche.

I could not agree more. Bring it on.

It all boils down to that. So if one can get a modified Zenoah so that it weighs less and develops more power and torque, then match it to a heli that can take it, you can get some great performance as seen in the videos here.

Relative to the video in that post comparing to the performance of a 50 sized G-20 powered heli;

Here is one that better illustrates the potential of a G-20 powered gasser.
