I am currently considering a gasser to cut down on the fuel bills. Just wondering if anyone is 3Ding a gasser and has any reccommendations. I was condsiering a modified Futura SE or the new Cuatro.

Also, anyone using the new Zenoah 230, I heard its giving out almost 4 Bhp!!! I would have thought this amount of power is more than enough to get some good 3D performance.

I know the extra weight would not allow for extreme 3D but the smooth stuff should be possible??????

Regards

PAUL

Gassers are the way to go!!!!!!

My Bergen Intrepid from http://www.bergenrc.com is very good. It will not do climbing tumbles yet.... Larry Bergen is modifying my Zenoah into a light weight RC 230. It will have the same power as the "RC230" but will fit in my airframe and have a lower weight.

The best blades for the gassers are the tapered NHP razor pro 71cm. They auto great and don't load as much as other blades.

By the way, I have a 3DNT and a Sceadu 50 and the Bergen is my favorite! It is also the most economical of them all.

You don't know what the .... you are talking about. The Zenoah is extremely reliable when compared to glo engines. Mine has been abused for 90 plus gallons of gas and starts everytime on the third pull and has NEVER flamed out!!!!!!!!
You are correct in saying to buy a 30 size to learn 3D. They are alot cheaper to repair.

Last year I saw the gas Bergen Intrepid being flown at the IRCHA jamboree by several pilots and they were "3Ding" the hell out of it.

Squirrel,

Is there anyway of fitting a governor to the zenoah ????

My other concern with 3Ding a gasser is overspeeding the engine during 0 pitch man'vres tailslides etc....

Thanks for the replys guys

I have to agree with Squirrel, (gee, imagine that), Alexander you don't know of what you are talking about...

And, yes you can and many people do run govenors (I would think the Futaba GV-1 is most popular) on gassers...

The gassers are "a couple" of pounds heavier, but don't seem to mind being thrown around at all...

Yes use a gov. It makes the heli very very smooth. Mine is mounted on the top. I use the clutch shaft and made a wheel to hold the magnet.

First time for everything!

Are you going to the Jamboree?

I'm certain my opinion is bias but I run the crap out of my Bergen Gasser. It only weighs 1-2lbs more than my 60 3D depending on fuel load(12lbs dry, 13lbs fueled). You do need to space out your maneuvers a bit due to inertia, but the payoff is that they are super smooth, economical (unless you crash a lot), and the tourque band of a gas motor is MUCH more tolerant for 3D's changing load demands.

As a side note, the Bergen Gasser runs all the same parts as the rest of the Bergen machines, so repair costs are almost identical to that of any other machine.

You'll pay a slightly higher price for the Gasser(which comes with the motor) but the economy alone will pay the difference twice over in a year. I pay about $2.50 a flight on my 3D 60. The gasser costs me a scant $0.10 for the same amount of flight time, and I can carry twice that in one tank. I actually get two flights on one tank of fuel.

You can certainly fit a governer to the G23 the same way you do with any other motor. I find that overspeeding is less of a problem with my gasser because of the wide tourque band.

With 700mm blades, the disc loading is actually lighter than the average 60 machine running 680mm blades. Of course the Fury is a tough one to beat for light disc loading.

The 2.25Bhp turned out by the standard G23 is not the same 2.2Bhp turned out by the 60 size glow engines. As I mentioned, the tourque band is MUCH wider on a gas motor, therefore it is MUCH tougher to loose head speed, the engine keeps it's 2.25Bhp even as RPMs change. Even though the G23 is borderline to carry a 12-13lb macine around, with my setup I can do continuous rolls, flips, and tumbles without a loss of head speed.

The Hanson Modified engine does turn out some more HPs, and this macine would be a 3D monster with it on there.

3D is risky with any machine not just a gasser. I agree that you need a bit more room to let a gasser stretch it's legs, but when you do, you'll fall in love.

Don't let people talk you out of it, go and watch one fly. I will have mine at IRCHA and I'm certain there will be at least a couple more there.

IMHO they are the greatest thing scince sliced bread, unless you want the endless power of the 80/90 heli, then you can go ahead and pay the $2.50-$5.00 per 10 minute flight. I'll stick with my "fly all weekend on $2.50" machine.

P. S.
On the downside, you need to carry a bit of oil with you, as a gasser doesn't oil itself and all your radio gear. You don't get to carry ; a starter, battery, glow clip and various other field support equipment to show off to your fellow fliers. Just take the bird, a can of gas, radio and a few drops of oil. Well, maybe that's not a downside.

I LOVE MY GASSER!

fury gasser
if they ever make that fury gasser like rumors are saying. i will sell my fury expert and buy it! i also am sick of glow fuel prices they add up to alot of money @ the end of the month

Alexander,
Of course when you compair the gassers with a 30/50 machine there is a huge difference. Make your compairison with something equal to the gasser, say a quality 60 size machine. There will be almost no difference in the repair bills. The fact is that the gasser is a huge savings when you make a proper comparison.

My gasser is way smother running then any of my other glo machines. The fact is that the hit from the gas ignition is much milder than the nitro (or you wouldn't need a larger motor to get the same HPs) so you end up with LESS engine vibration.

Last year with only an average amount of stick time my fuel bill came out to almost $600. That same amount of stick time on a gasser would have cost me $30. Thats $570 worth of crashing for one season, and I'd still have my crash budget left to spend.

Take it steady guys !!!
Alexander makes some good points. I personally haven't done alot of research on the subject, G230 output power, at what rpm etc my knowledge is based on general club chat.

I am currently flying a Millenium with an OS 61 WC running 15% nitro. Current fuel consumption is 7-8 gallons a month. With the higher fuel costs over here in the UK and Europe in general the gasser seems worth considering.

I would be keeping the millie so would still have a glow 3D machine.

Thanks for all the replys guys, you have made some interesting points.

Please clarify. Are we talking about 3D or aerobatics? I don't think flips, rolls or climbing rolls even are necessarely 3D. They fall more in the definition of aerobatics.

3D to me includes :
Flight - forward, backward, sideways, pirouetting, knife edge + the inverted equivalent

Piro flips, Piro loops, Funnels, Tumbling Circuits, Death spirals ......

And my personal favourite Aerobatic Autos

Alexander, it sounds as if you need to get a newer version of a gasser, any brand, as the things that you point out that are wrong with your old gasser are not issues with the current, newer gassers...

There's a reason the leading 3D pilots don't fly, and aren't pushing the use of gassers for 3D. I wonder why that is?

When your glo fuel is free why bother saving money with a gasser. Do know that methanol is around a $1.25 USD alot of money is made from selling fuel that is why the hobby dealers don't try to sell the gassers.

They get everything for free and use what performs the best. I believe the point was they don't use gassers because they don't perform as well.

Cheap Flying
As a former gasser owner, I would not recommend it for money savings. My cheap flying heli of choice is the Raptor 46. Of course raptor part are cheap and the OS 46 sips gas(less than the TT36!). The OS 46 cost less than the OS32 and it runs just as good.

My X-cell gasser flew great and would flip and roll all day. The major down side is the rather large devet you leave on the plankers runway and the $400 hole in the wallet.

A Raptor 60 replaced the gasser and they fly about the same. Even with the cost of glow fuel, it's easier on your nerves if you know the crash cost will be lower. Although, as I continue to suck down glow fuel I'm not so sure getting rid of the gasser was the best move.

Just one mans two opinions!?!
