I have Great Planes CAP 232 40 but I'don't have engine yet. I was thinking Saito FA-100 but would it have too much power for this plane. I have SuperTigre GS-45 but that is too small for 3D flying.

I have made little changes to plane. Now it has bigger ailerons and there is two Hitec's 85BB servos moving ailerons. I raised the rudder servo so now it's it the fuselage and I'm planning to install smoke smuffler too.

saito 100 !!!

While the 100 can be crammed into the cowl and with the other items you plan it would be a very heavy wing loading for that size plane. A Midwest "Lil Cap" would be a better platform for the 90 to 100 engines. Go with the GS-45 for general flying or a 63 to 70 4/Stroke.

EXCAP232

ville....oh boy....I had one. Did the same thing, hs-85 in wing and elevator. One on each side. I put a 61fx in it. Well....

I have g2 and the cap flys the same on the g2 as mine with the 61. REAL hard to hover. I put a 46 in it on the g2 and it hoverd great. the cap didnt last long enough to get a 46 in it. the elevator flutterd.....I saved it some how! took it home and put stock servos in the tail. that cured the flutter prob in the tail. the next week end i flew it i got two tanks on it. the third tank the ailron flutterd and it went in......HARD...there wasnt much to pick up.

i hope you listen to my warning....I loved the plane and will build another in the future but, it will be a os 50 or irvine 53 or ys 63. Nothing heavy for sure. build light with stock sevos and only 4 servos. the plane didnt respond to flaperons. I did like the bigger ailrons though.

good luck!!

OK, maybe the FA-100 is "little" too big for this plane.

I have hs-605BB servos in both elevator and rudder. My aileron servos are between R-4 and R-5 ribs, so there shouldn't be too much loose in the pushrods, but maybe I change the servos to hs-225BB.

Which Irvine 72 or OS 61FX would be better for this plane? I know that there are CAP's that have Saito FA-91 in the nose and still flies just great.

yes the 100 is more than you need. But, on the other hand the 100 s size and weight is almost identical to the 91 saito. I have also seen this plane fly wonderfully with the 91 saito. Therefore I would do it......however.....you must know how to fly this type of combo......if you try to fly it like a pattern plane or war-bird and prop it with a 13X9 13x10 12x12....the motor will pull the plane apart.

if you use a low pitch large diameter prop ...fly slow and let the torque of the motor muscle you through the maneuvers at low speed I think it will work fine......

i think the 100 is extremely big... I suggest a .70 or .80..... that would be fine.. how much you enlarge the surfaces??

Ailerons are about 5cm/2'' wide, and little longer than originals. Very near the real CAP's dimensions. I had to made some changes to the wing: I moved trailing edge forward and I made new ailerons from foam what is laminated whit balsa. I made new wing strip next to R-4 and aileron servo is between these two ribs.

Saito FA-100 isn't so heavy but it would have so much power that CAP can't use all of it ever.

I built mine stock and at the time I was having the same dilemma. Saito 100 or 91?
Keep in mind that GP calls for an OS70 at the most for a 4stroke. I was also trying to keep the weight down and although the 100 is more powerful than the 91 and about the same weight (but heavier) the 91 is a lot more powerfull that the OS70 and about the same weight or lighter to boot. Now Factor in the considerable more expense for the 100 versus the 91 and I think the choice is clear ( at least it was for me at the time....I got a 91 for $200) I started flying with a 14X6 and switched to a 15X4W for 3D. Great combo.....it floats in as slow as you can dare. Watch out for the elevator though. Given the right combination of throw and airspeed and it will tip stall on you without too much warning.
I had to butcher up the cowl pretty good to fit the engine in and I had some overheating problems. I think my fuel line is too long and makes for a lean mixture but not absolutely sure.
Bottom line the 91 suits this plane perfect IMHO. Enjoy!

I had the OS .61FX in mine. It was probably the best engine, but this plane and engine combo was not perfect. The wing loading was still to high for the slow vectored thrust 3D maneuvers. It did everything else really well and flew beautifully.

Maybe FA-91 is my choose too, but here in Europa the engine cost almost 400$

Why not go the YS .63?
Should get it for alot less than 400US from singahobby, www.singahobby.com

Should have loads of power, unless you build a led sled!!!!!!!!
I dunno about the weight side of things, but I imagine it would weigh less than the .91 or 1.0 saitos.
More reliable fuel draw, and for smoke just get one of those hien smoke systems from japan, supposed to weigh very little, (4oz or something rediculous).
Anyway, that is just my opinion.

Singahobby seems super but where are the prices???

OS 91FX or YS 63 .... the 91 obviously a lot more powerful, but the 63 just as adequate.

Yeah it's a pain that they don't show their prices on the website, you have to email them to find prices, they will respond to your mail quickly, and will also give you a quote for insured airmail to your location.

There prices are similar to or better than - http://rotor.com.sg/

I ordered a Seduction Freestyle from singahobby, they gave great service, and four days after I order, the package arrives on my doorstep with no damage at all!!!!!!!!

I will buy a YS .63 and T9 cap, through them now. I was quoted about 460 Singapore dollars for the YS. (+ shipping)
(Thats about $265 US)

If I ordered engine from outside Europa example from USA, I'd have to pay 22% taxes when it come in EU.

YS63 cost in www.znline.com 322€\$.

What would be good prop for YS63?

I have no personal experience with the .63 yet, but the APC 13x6 seems to be the popular prop.

I am thinking of also trying the bolly Clubman 13.5x6
From what I read, the engine likes the 10,000 -11,000 rpm range.
So prop it with what ever suits your flying style and keeps the rpm in that range.

I had a YS63 on my GP cap 232. weight was 5.5lbs with 2 aileron servos Hitec 225BB

I had fiberlgass cowl, and wheel pants. My plane last less than 10 seconds, then destroyed its self on take off.

CG was way 2 far back. I bought kit when they first came out. And didn't build it until a couple of years later, and the CG in my manual was about 1" back further than what they now recommend. So needless to say, my Cap 232 was, the best looking plane I have ever owned. But I can't say how it flew because, it rolled inverted right after take off, and I didn't have enought aileron programed in on low rate. Once I got the plane stopped from rolling it was eye level inverted with full right stick. by that time I was so puckered up, it crashed, demolished. just about everthing. I learned a very epensive lesson, always do maiden flights w/ high rates on take off.

But back on the motor, when I was building mine, some people where putting in Saito91, and had great results.

The .40 Great planes Cap is my next project after I finish my Carden Cap.(March 01) I am of the opinion that a light engine should be used. I plan on an OS 50sx. This will keep the weight down so the plane will do other things other than hover/tork.
I had a 50sx on a 5 1/2 lb big stick arf and it would pull it out of a tork roll with authority. How much is needed?

Mike, and others that built this airplane, do you think less than 5 lb is achievable? What about moving the hinge line on the ailerons?

Thanks,

Jess

I am sure 5lbs could be done, but it would take a lot of chopping and replacing to contest grade wood in some places. The wing there isn't much you can do on the wing ribs, because they have already been lightened. So you have to work on the fuselage.

You will be able to take out all the wood under the canopy and then cover over it.

Fuel tank platform, carved out to be lighter, and a few formers, sanded down. But there really isn't much to ligthen. But I think it wouldn't be to hard to drop a couple of ounces though.

I have pieces of the fuse, in my attic, when I get a chance I will post some pictures. I have the entire fuselage except the first 3." right side of a wing.

I paid to have my cap built and covered. the guy that build it, is a great builder, but he doesn't chop out much wood.

I would really like to fly this plane, to see if its a good plane or not.

I built one and modifided the hell out of it. 61fx motor, 2 inch ailerons, two elevator servos....blah blah blah. I liked the ailerons.
heres what i would do if i did it again.
Dont take the diehreal out. I did and it took tons of mix to get it to knife right.
Do the 2 inch ail.
Put a light motor in it. The 60 was to much. It would tork roll real fast by it self. plus it was REAL hard to hold in a hover.
Just use one servo for the wing. Flaperons dont do any thing for the plane.
Build as light as possible. If you swap a few things in the kit it could be 5 lbs no prob. Stuff like glass cowl and new push rods to the tail.

I had 4 stock servos and two mini's and a 61....came out at 6.5 lbs. I think os 50 or irvine 53 would be perfect. 4 strokes'...ys 63 or satio 72.

hope this helps

I have also built a couple of these with modifications. They include mounting the tank on the cg, removing approx half of the dihedral, (very little coupling now) 2 aileron servos, pull/pull rudder servo, lowering the stab 1/2", replacing some of the wood with better quality stuff, and lightening the fuse and wing. I used a OS 46fx with a slimline pitts muffler and an APC 11x5 and 12x3.5 props. This combo will hover and TR at about 2/3 throttle.

Hope this helps,
Bryan

Did you use fuelpumb or just the muffler pressure?

A buddy of mine said he got his down to 4.5 lbs with a 46. He said that he took all the lightening holes and outlined them all 1/8" out and took all of that out.

I also have one, I see wood everywhere that can stand a diet. I also made the ailerons bigger, it was like night and day compared to the old ailerons.

Howwwdy!

I have a ST .61 2 stroke Im looking at putting in my lilcap 232. It seems that .60-.91 engines are the size of choice, but it sure would be nice to hear flight experiences with a .60 engine. I live at 4500 feet, and they like to put 'em in bigger than the plans call for here, but would this really make alot of difference in this plane?

Thanks,

paul
