That's the one I'm talking about the Old Matt Chapman's color scheme looks neat (to me anyway). Plans say it should weight between 11 to 12 1/2 pounds and has 1031 sq. in. 73 in. wide wing.

With a saito 180, what can I expect my all up weight to be? 11-12 lbs?

Both of ours came in right about 12 lbs with Saito 1.80.

i was replying to rcpilet on the wing area but if you want to try a 3w-24 which it seems they dont make anymore i would say go for it. i may not have the experience to say that it flys better on glow as opposed to gas but i know it will fly. i saw a guy fly a hanger 9 funtana 90 on an Evo 26cc with a tuned pipe. i have also heard all the hooplaw about how its impossible but i saw the video. i have this plane and i will admit its heavy. but you cant have fun in this hobby if you dont get to experiment a little and rely on what everyone before you has said. the 3w-28 is 2 lbs 10 oz with everything according to thier site. probably run an 18-8 at 8500 rpms. i honestly think that the weight difference would not be much different between those setups. have fun with it.

Carlosponti,

I think the 3w-28 is just a more up dated and more powerful 24, and are the same size and weight (maybe).

do you already have a 3w-24? if you dont you might as well go with that 3w-28. a friend of mine swears by 3w has a 100cc. he had it on a hanger 9 sukoi but now has it on a yak 54.

1.20 sized glow planes just do not, nor have they ever, done all that well once a gasser was tossed on the nose. Period!! Those that just want to go fast and hover all day will be pretty happy, I suppose, but if that's all you can do why not do it cheaper with a Something Extra or similar.

Just about every manufacturer out there advertises the weight of their engines with only the engine. It never includes the weight of the muffler, ignition module, ignition switch, ignition battery, etc. The only exception is a company like Zenoah that has a magneto instead of electronic ignition. If gassers were more powerful, then why the heck do we use a formula to size a gasser that comes out at 1.5 times the size of the suggested glow engine?

You want a good flying Cap? Then make it light and watch your c/g. You want a "Snappy Cappy"? Then make it hevy with a forward c/g. Either of the last two will doom most Caps in short order. Even if you just ahppen to be real good.

I'm a gas flyer all the way, but if the plane was mine I'd be dropping a Saito 1.80 on the nose and having fun. A gasser will just make for a lot of work for the installation, turn you into a Nervous Nellie for a few flights, then bring nothing but grief. Course, that nice, expensive gas engine you had up front will take most of the impact, and leave you with all the prestige of a gas engine owner with no airplane to fly.

BTW, a good intro to gassers starts at about the 50cc level. The stuff below that is pretty much a waste of time and money unless you fly things like Cubs and WWI biplanes.

Yes I already have and 3w-24 that's why the question. But since my CAP flys fine for me with the Thunder Tiger 120 I will just keep things the way they are (this plane is 6 or 7 years old if it's a day, I got it second hand (had a saito 150 in it). Now that its getting to the end of it's trail I was thinking about gas. I have another one new in the box when I get around to building it I think after eveybody's input I will go with either a YS 140 sport or a OS 160.
Thanks

Have a look at this build/fly page, H9 CAP 232 1.20 with MVVS 1.60: http://home.flash.net/~jecramer/h9cap232.htm

Seems to me I saw the same set-up somewhere in the Dick Hanson domain a couple years back. The new Evolution 26 is basically the same engine. Put their MVVS pipe & header on it and power is no problem. Some people don't like the look of a tuned pipe hanging underneath, in which case you can get the in-cowl can muffler for a better looking, little less but still adequate power solution.

So add the weight of a heavier gas engine and all the basic gas accessory requirments and then toss some more weight at it with a pipe and headers? Is that correct?

I think I'll fit a G-26 to my Mini Funtana so it will have better vertical

I already said that. Nobody was listening.

Okay, SilverSurfer just said basically what I already said. At least listen to HIM. He's probably got 4 times the experience I have with planes.

We're both telling you to use a glow engine for a glow plane. Leave the gas for the bigger birds.

When I got my first 1/4 scale, I thought I was DOWNTOWN!!! Now I'm flying 27% and 28% and even a 33% plane. They look small compared to a 35% or 40%. A 25% plane isn't all that big. When it's your first one--it's a HOG and you'll be grinning so hard the corners of your mouth will touch on the back of your neck. But it's just not big enough for a gasser.

To each his own. I am not one to push people into gas before they decide to make the move for their own reasons. I still like my 1.60FX and my Moki 1.80. I agree that 50 cc is a good hump to get over, but there are a lot of well-proven combinations with smaller gassers, and the MVVS/Evo 1.60 is definitely part of that scene. The thread-starter wants input, I'm giving input. Controversy is not my bag. As to installation and operation headaches, I get them from any new engine, glow or gas. But they're all good once you sort them out.

10-4

And yes, pretty muh what my original post said was a reiteration or confirmation of what Rcpilet said. However you chose to look at it. The man is dead on target. At 25% you can run a gasser, but the trade offs are upside down, IMO.

Ok. I am pretty much set on a saito 180. I don't know why everyone voted on the OS 1.60, I don't think anyone has even talked about it in the thread. Everyone agree a Saito 180 would be a good chioce Power & weight wise? The manual suggests a saito 1.20-1.50, but the 180 is just 1 ounce more than the 150, and fits in a 1.20 mount.

Thanks

i like to experiment why is that so wrong to some people. i bought the plane for 100 bucks at a swap meet. so sue me if i would like to do more with it than just fly it. its all in what you want. if you want to hover all day and not much else then fine. i like the challenge of see how i can do what is said to be impossible. and my guess is that some havent played with a modern 26cc engine in a while. try it just for the heck of it. itll be fun i promise

I think a 26cc gasser would be cool, but I think for me, I will reserve gas for a 27%er and up, just so I can keep my wing loading low.

I have the SIG Extra 300XS, which is about the same size and weight. I put the BCMA SPE-40 on it, and it has more than enough for the plane with minimum weight. Swinging a Xoar 21X8 it's putting out almost 21# static, and this engine only has about a gallon and a half through it.
AUW for the plane dry is 12# 8oz. Also, once you go gas, you'll never go back. It's nice not to wipe all that glow goo of the plane when your through flying.

Silversurfer and RCPilet
I'm sorry, but I must disagree with your logic. I have a 40 gas on a 1/4 scale as mentioned in my previous post, and it flys just fine. Pattern 3D IMAC or just sporting around the sky. With todays gassers it is possible to keep it light and CG can be had with little or no added weight.
Like I said my plane is 12# 8oz with a CG of 30% MAC and the engine is putting out almost 21# tatic thrust. To prove what a smooth flying plane this is I can only say this, It's my firt plane after a trainer, and I can handle it with no problems. (of course I don't do anything more than sporting around the sky, and a loop or roll here and there) If your ever in Cincinnati, drop me a line we'll take it out, and you can see for yourself.

the hard about gassers is that, when "they want", they will risk your plane. Maybe I´m just a bored, but, think about how many big scale planes you have seen crashing , and , think about how many times it happened because of something related to the engine.

It is all the time, interference, bad spark timing set, acel. failure, too much heat, vibration, etc...

Well, this has always been that way, somebody that has 30 years experience will say something and a guy that just stepped up off the trainer will say the opposite and think he is absolutely right.

At 12.5 lbs, the H9 Cap is just too heavy. Drop the gasser and put and OS 160 or Saito 180 or even bette a YS 140DZ or 160DZ and see the weight come down to 11.5. That will make a hell of a difference!

I more than just stepped up off a trainer but I do not have 30 years experience...

I don't have the Cap, I have the SIG Extra 300XS, and it's target weight as stated in the manual is 12-13#. I don't have much flying experience, however I do have 19 years engineering experience, and a machine is a machine, and a plane is a machine.
