My Posts This: Topic  Forum		I'm looking into buying a Raptor 90 SE kit, but have one question should I buy the gasser conversion for it, or just stick a 90 size nitro engine into it?
What are your takes on it?

My Posts This: Topic  Forum		Totally dpends on the flying you do IMHO. if you are hardcore 3d, nitro all the way. Scale or sport, either will work.

My Posts This: Topic  Forum		The gasser will do everything you want but it’s just a little less powerful than a 90 nitro. The big advantage of a gasser is low cost fuel and 4 times longer flights. The new gassers have better performance than the old ones of a few years ago.

My Posts This: Topic  Forum		I would like to give that Century 50 size gasser a go to compliment
my 50 size nitro. Even though it has less power, the fuel
efficiency and cost will be huge. I mean, 15% around here cost
$18 a gal by the case, whereas gas fuel is $2.35.

To really put things in perspective, lets say if you can fill up
the tank 10 times per gallon and nitro gets 10 mins of flying and
gas gets 20 minutes of flying, that equates to double the amount
of airtime for 87% difference in cost per gallon of nitro to gas.
Thats huge, afterall what makes a better pilot? Airtime.. pure and
simple, it's not how much you're paying per gallon.

Edit: didn't add oil cost to the gallon of gas, but its still well under $5 a gallon.

My Posts This: Topic  Forum		RappyTappy
you got a point there, I was thinking the same thing, but I was just wondering for those who fly gassers is the lower running cost worth the loss of power?
how big is the loss in power, and can you make it up by gearing?
I mean from what I know from the land based stuff, the gassers have alot more torque than nitros!

My Posts This: Topic  Forum		I have been flying a Century Predator gasser for a little over a year now. I really like it a lot, plenty of power for me to fly my aerobatics. Even with $15/quart oil it's really cheap to run on fuel. A tank of gasoline will run a lot longer than the same volume of glow.

The down side to gasoline is they are quite a bit more expensive to buy and crash. The extra weight makes the same crash more harsh on the frame. Also, you will feel the extra weight when throwing it around. that doesn't bother me but if you want the "pop n lock" flying then gassers are not the way to go. Having said that mine performs pretty well and moves a lot quicker on the cyclic than most would expect.

If I had the $2000 in my hand again I think I'd still buy the gasser. The one issue I have with my Predator is the crown gear driven tail. It's more of a setup hassle and less forgiving on tail blade strikes.

If Align or Thunder Tiger would make a 700 size gasser they'd own the gasser market.

What ever you do please read up on any gasser conversion kits for the Raptor. The only one I know of is sold by a liar/thief who is sells stuff as his own design that he ripped off from others. Specifically what he did to Tom Fiddler with the Stator Gator was inexcusable AND he bragged about it.

Here are the posts around what Paul did to Tom

My Posts This: Topic  Forum		How about this thought...

With the volitility of gas versus nitro, don't the chances of a catastrophic fire go way up. I mean having to replace your gas bird every time you crash would not be cost effective at all.

Thoughts?

The reason that address is *'d out is Mark won't allow it. That's the website of Paul Macha - the thief and liar I referenced above. Read through those posts before giving that guy any money. Again I stress, what he did to Tom Fiddler was just plain bad, in a personal way.

In my book your rear facing conversion is the most creative and if you can mass produce it many people will buy especially if you can accommodate the engine use by the other ****ufacturers such as Min Air, Century, JR, Hirobo.

Keep up the good work and since you're in Taiwan, you probably should submit your design to Thunder Tiger and Align and remind them that somewhere out there, there is market for gasser and not everyone can fly like Colin Bell and Lukas Riva.

My Posts This: Topic  Forum		R gassers any good at 3d?
I was told no, but I've seen vids of them on you tube, they seem a little slower than 90 size nitros, but looks like they may not be too bad?!

My Posts This: Topic  Forum		I 3d my gasser.
Tic tocs, flips, backward inverted circuits etc etc.
A gasser with a hot motor in it will perform pretty well anything a nitro will, just slower and requires a different approach to 3d.
I spent the extra $$ on a Modified motor by Hanson, called the 3d Max.
Makes more power than a stock Zenoah, and vibrates way less.
Money well spent if your even thinking of doing 3d with a gasser IMO.

If you bling it, they will come :D

My Posts This: Topic  Forum		Maybe I misunderstood? You have flown a coaxial and the little novus only? If this is your skill level you are getting in way over your head IMHO. This heli your looking at is not gonna stay in one piece. And will not be the only heli you're ever gonna buy. I dont aspire to do 3D which takes a few years of endless practice and $1000's of nitro less with gas but more with repair parts. All helis do 3D except mine I have seen some nice gasser flights its the pilot that doesnt do 3D. If you go 90 or gasser how frustrated will you be when you have the few hundred dollar repair parts order every week or two? I have seen many people quit because they cant stand a $50 bill for an electric!!


I went for a used .30 cause the expense was so very very small but its lacking the insane power for 3D with the OS32. But its great for flips loops rolls normal aerobatics and an awesome trainer to learn all orientations basic heli setup.

My advice what ever thats worth would be to slow down a bit buy a used 30 with a good OS37 get all the basics down then go for the gasser once your basic flying skills are developed.

Or just go for the little more expensive 50 and learn everything even 3D by then the gasser conversions will be plentiful and maybe TT will finally release one. Not to mention gasser motors have gotten better over a few years they are sure to get even better.
