After three years of intermittant labor; this plane is starting to take shape.

If anyone else has built this plane; I was wondering if they had to add weight to the tail. Mine seems nose heavy. I have an OS 1.08 FSR w/bisson pitts muffler on it. I still have to rig the fuse with electronics; maybe that will make a difference

Finished covering the wing today. It's dark red Monokote, white, and black. Pictures make the red look orange.

Mine has a 1.60FX mounted in the nose and balancing that required putting a pair of Hitec 605's in the tail. Mounting the servo's in the tail took a bit of engineering but I think it was worth it.

With a 1.08 FSR I can't imagine you needing weight in the tail to balance it. An idea I used to get a bit more weight back in the rear was to change the flying wires from the supplied 2-56 rods to 4-40 with metal tabs and the du-bro solid ends with screws, seemed to add up to a couple of ounces which helped in my case. The strength was also appreciated during the lerning curve with this plane as I flipped it over a few times getting used to it, and mine is the "new" redesigned kit that isn't supossed to do that.

One change that made a HUGE difference in the way mine flies was to put the Cline fuel regulator on and move my tank back to the CG. This got a bunch of weight out of the nose and really helped smooth out the take offs and landings, and eliminated the nose overs.

Mine weights in at 13 lbs with the 1.60 and flies very good. With your 1.08 it's gonna fly ok but I bet the airbatics won't be very "pro" unless yours weight a LOT less than mine does! Either way it looks great in the air and very realistic.

The C-pro needs a lot of aileron differential for smoothing out the turns, otherwise it has one of the worst cases of adverse yaw you have ever seen and needs a LOT of coordinated rudder just to turn it.

I was under the impression that this plane would be a real *****cat in the air. From what you've described it sounds a lot like a Cub. Mine too is the re-designed kit, hopefully your 1.60 is the culperit. Can you Torque-Roll your CP?

Geeeeesh, can even say *****cat?

Oh it is a gem in the air, easy to fly and yes many traits exist that resemble the Cub, like the adverse yaw isue. The plane has a LOT of drag and needs power to do aerobatics. Remember that the real plane this one is modeled after was designed for doing competition aerobatics. I decided I wanted to be able to emulate that ability and considering the weight mine came it at the 1.60 was appropriate. While it might sound like overkill it really isn't, at least in my plane. At full throttle the 1.60 has good vertical and pulls the C-pro through the nicest loops you have ever seen. Due to all the drag the plane won't fly fast even with the big 2-stroke at full power. As for torque rolling it, the plane doesn't have nearly enough rudder to even think about trying that maneiver at my skill level.

I did a lot of reading before choosing the engine for mine. The few info sources I found said that they would like to have more power since their planes were "anemic", and they had 1.50 four strokes on theirs. All that leaves is the 1.80 Saito and the 1.60 OS or the Moki 1.80. I got mine solely based on the cost, with slimline pitts muffler about $300.

I think it all depends on what type of flying you like to do and what you intend to do with the airplane. With the 1.60 belching a nice big exhaust trail and inverted 5 feet off the deck comming down the runway, my C-pro is a real attention getter and crowd pleaser.

Any way wou cut it the plane is great fun and chances are you will be the only guy at the field with one of them.

Got one with a Saito 120 up front, elevator servo and rudder is in the back, flies great.. 1/2oz lead in the tail...use differential on the ailerons
Big and Pink....

Got a picture Big Bird 1?

Nice looking wing Gene

I did have one in the gallery...Mmmmmmm, let me go check.

Nope...gone...
Will try to post one tomorrow

Thanks again Gator.

It wouldn't have turned out as well; had it not been for guys like you willing to share your trade secrets.

You could have had the market cornered; and guys like me would be sitting back scratching our heads, and wondering, " how did he do that?"

Not that my skills are close to yours yet. You are the man.

Was VERY dissapointed in my Pro Airbatic performance. Has a Super Tiger 90. And yes it fly's like a Cub. Maybe it needs a G26. Either way it looks like a candiate for floats.

Rekitted

Cub!?! I don't wan't no stinking Cub!

I guess if I don't like it I know a few Cub collectors that might.

The Citabria Pro will only fly like a Cub if you power it like a Cub. The recommended engine sizes that come from BUSA are clearly all to small for a plane with an 80" span and weight of around 11 lbs. The kit has been around for quite a few years and the recommended engines were all appropriate when it was first put on the market. With todays light, powerful engines being available, why use an engine that is obviously to small for a plane of this size if you want to fly aerobatics with it. If you take the size and weight into consideration for an aerobatic plane it's pretty clear that it will take a 1.50 four stroke or a 1.20 2 stroke, or more to fly it right. And don't forget, this is not a Cap or an Extra, it's a scale aerobat of a plane from an earlier era and it flies like one, not super precise but very capable nonetheless.

From what I have seen the majority of people that have built and flown this model and are displeased by it have all underpowered it. That's why they always say it flies like a cub...

Fuse is shaping up nicely. Second picture is my logo on the vertical fin.

Looking gooood!

Wish I had enough imagination for a covering job like that.....

Very nice, I couldn't settle on anything specific when I covered mine so I did the old prototype scheme, looks good in the air but all to common for this airplane.

Any chance os getting a nose shot?

The nose isn't much to look at yet.

I'm working on the fuse sides right now; and the pants and cowl are still white.

I'll post again when I have something worth looking at.

Your C-Pro looks great. I am on a bit of a budget, so mine is taking forever. Started working on it in September. It is all framed up, and I am in process of installing the servos etc. I am saving up for an Enya 1.55. I here it flies the pro very well, and when mounted inverted, it fits in the cowl without cutting a big hole in it. I like the four strokes for this, since I want to do the prototype scheme as well with more of a scale sound. Will post pics when I get them ready.
At the rate I am going, I probably won't get her covered for about two or three months from now. I hope it will be ready by spring.

Or else......[]

After shogun talked about mounting his servos in the tail, I can't help but think I should do the same since I am using a 34 oz motor in the front. I am also mounting the tank over the CG. Maybe by mounting the servos in the tail, it will lower the weight a little by getting rid of the balsa supports and the control rods?

Patriot

Kinda bums me out, since I already have the servos and control rods mounted. []

That's where I have mine....
One for the rudder and one for the elevator.....didn't have to add any weight with a Saito 120..
Built platforms where space was just wide enough to for the servos to fit in between the stringers.

I think I am going to leave the servos where they are (in center of fuse). I am using Sig Koverall to cover the plane and Rustoleum paint with two part PPG clear pearl coat to finish it off. I am thinking that since I am using fabric with a few layers of paint that it may weigh down the tail enough to make up for the differance somewhat and help minimize how much weight I need to add to the tail when finished.

Patriot,
You could go ahead and build the servo pockets in the tail and then cover over them with the fabric. Id the plane won't balance you can simply cut the covering out of the pocket and mount one or both of them later. It would be a LOT easier to do it now and have it available should you need it as opposed to ripping a bunch of covering off later and having to redo it after building the pockets in at a later time.

just about done painting
