Has anyone tried this combo? I currently have a GP Extra 300S .60 size and while it's a great flying plane it lacks on the 3D. I'm looking for something that's a little wild yet scale looking too. I also have a Morris Knife with a Saito 72 that's a blast to fly but again I like the scale looking airplanes.

So how is the GP CAP 232 kit and would it scream with an OS91 FS? I haven't had glue on my fingers in almost a month and I'm going through withdrawals... Hell I've already built three kits this year.

i flew mine back in the day with a satio 91 and it would was a cap at 3d, except the harriers and elevators. Knife loops like it was cool but that planes rudder is close to a 1/4 scale size. Mine was on one elevator servo on the stick and wire. This could have had something to do with the elevators and harriers as the 1/2 never did quite match up, along with i build it with only one servo for the wings. you know the deal live and learn plus i was to new at kit building to kit bash it. the plans call for some upthrust about 2 degress. The plane did track well; however, the landing gear area is a very weak the way its built per the planes. Its just a butt joint piece of 1/4 ply. It will come of with the easiest of landing. talk with you soon .....

I'm heading home in a few minutes to final sand mine and get it ready for covering. I researched this plane extensively and the majority of people say it can do 3D very well. Most of them agree with krazyrc that it lacks on the elevators and harriers but I don't recall anyone trying to reflex the 2 wing servos on the elevator and compensate for the wobbling(sp). That's basically my mission with building this kit I wanna make it do harriers I'm building mine with a saito 91. I think the OS will be really overweight for it. (Saito 91= 520gr OS 91= 655gr per tower and horizon)
I know a lot of people had success with it by using the 72 saito also.
Other than the 2 servo wing(HS-225s) I also reinforced the gear plate a bit with some triangle stock. Hope it will hold like this cause everyone agrees that this is a weak area. I'll be using HS-605s for the rudder and elevator which I beveled a bit more to make sure that throw will not be an issue.
Assembling the 3 piece cowl was a pain on my neck and after cutting and painting it ended up 4,1/4oz. I think that is a lot for a 40 size cowl....any thoughts on that anybody? I've put an order already for a glass cowl that I will use after I have a few flights on it I'm trying hard to keep it light but this being my 3rd plane overall and the 1st kit I don't really know how it's coming until I weight it when it's done.
I'm hoping to finish it soon so I can finally fly it. This kit building business is really time consuming

Wreckrman2,

I had one a couple of years ago. It was my 3rd plane and 3rd kit. I had an OS 70 on it and it would hover at 3/4 throttle. Plane builds light and strong. Mine had over 300 flights on it. I flew it for about 1 year and yanked the landing gear out 2X. I did move my landing gear as far fwd as poss due to tipping over problems. This plane will 3D quite well. Great waterfalls, hovers, lomchevaks and spins. Does a great inverted flat spin. I never tried elevators or harriers with it. I built mine as per the instructions without any bashing. One of my friends now owns it and he tore the vertical off of it. Its back flying again, probably has 500+ flights on it now. It is definately a plane that you will enjoy. With a Saito 91 on it, it should be a rocket. I don't think you should have a problem with the balance either. I had to put the rx battery under the tank to get mine to balance.

Later,

Andy

Thanks guys, I know the OS91 is a little heavier than the Saito but I have this engine laying around and want to find a suitable home for it. I know I could use this engine but my concerns are raising the wing loading to the point it won't fly well at slower speeds. As for the cowl, throw that ABS crap away and order a fiberglass cowl from Stan's Fibertech.

The thing that attracted me to this airframe is because a fellow flyer has one with an OS70 FS. He says it's a really great flying airplane and I like the scale looks of airplanes. I have build the GP Extra 300S .60 but this engine is a little weak for it. I have a Webra 120 on the way for it. Call me crazy, call me stupid but like the power to get outta anything.

As for the Saito 72, that's a monster for it's size. I have one on a Morris Knife weighing 4lbs 3oz and it's a real blast...

You will love this airplane. I have one with a YS-63 in it and It's one of my favs. Just a couple of tips:

1. Reinforce the horiz stabs somehow - they are puny and my kit came with really soft balsa. I ended up putting in tail bracing wires, as I have one Hitec 225 on each elevator half.

2. Go with Robart hinge points or good Dubro or Klett hinges on the elevator and rudder. I broke about 6 fabric hinges and almost lost the plane when my rudder fluttered.

3. The fuel tank floor spans quite a distance, and mine cracked just from the weight of the tank. Put a doubler on it if you can

4. For your first flights use REALLY low rates on elevator, especially if your cg is a little aft. Mine needs a ridiculously small amount to fly smoothly and to not drop a wing on landings

5. Throw away the ABS cowl.

Hope it works out for ya.

I'm flying a GP CAP on a Saito .91. It was built carefully so it won't came overweighted when finished. It's wearing a carbon fiber landing gear, aluminium spinner and a fiberglass cowling (This is a bit heavier than the plastic one), and I can't take it down from 6 lbs . I found postive incidence in the main wing of about half degree, and I agree about the empenage thing.... whoever builds this kit should reinforce the horizontal stab as well as the landing gear plate. Mine is a bit tail heavy and I can't get it to hover....!!!! The plane sports a 13-8 prop... I've tried a zinger 14-6 but the weight-thrust relation is still 1-1 (6 - 6.2). A little observation is the height I'm flying at: near 9000ft over seas.
Any suggestions to make this plane hover are welcomed.

Norman, nice plane!!!!

Oh and it should be easy to get that plane to hover, you just have to fly 9,000 feet lower...

Seriously though, what RPM are you turning with those props? Maybe going to a higher nitro would help..

You might try an APC 14x6 or 15x6, maybe that 14x4W and I also think higher nitro will help...

Hahahaha, I see ya researching! Did you press that little yellow button yet? See Ya Later! Phil (Mesa, AZ)

Wreckman, I had this plane with a ST 75. Loads of fun, although, if I had to do it again would go w/ the kyosho arf(same overall cost and excellent workmanship on the one I looked at). I flew one with a os 61 and thought that it flew much better. I have attributed this mainly to my leading edge on the GP so yours certainly could fly as well/better than the Kyosho. I second the control surface comment, this plane stalls quickly(by design). It does the snaps rolls so quickly youll question if it actually did it. Using nylon bolts on the landing gear will help with those rough landings. I think it was on RCOnline, a fellow there went completely overboard on making this plane light, CF and Nomex all over the place, I think his came in around 4 lbs! I landed mine in a tree, RIP.

Nomex??? Ok, that's the first of heard of that application..

Of course it would have the added advantage of being fire-proof...

I have been thinking of putting a larger engine in my GP cap as well.. I fly mine with an OS 46 FX turning a graupner 12 X 5 prop at 12,000 RPM. I can almost hold a hover with it, and I am at 6000 feet in elevation. My only observation would be that if you increase power like that you are going to need a lot of right thrust, and a bit of elevater diffrential to keep the plane tracking straight in vertical manuevers. I have 2 degrees right thrust and a bout 2 degrees more up on the right elevater to keep it straight thru imac manuevers. Best 40 size plane I have ever flown. I have about 100 flights of pure fun on mine so far.

Cheers,

FW

Hey SunDevilPilot, I got a Webra 120 today for the Extra 300S... I'll let you know how well it works out. If this engine won't hover it then I give up!

Thanks guys for the information on the Cap 232. I agree the Kyosho is a nice airplane but I am a kit builder. I've built three so far this year and I'm going through withdrawals because I haven't glued my fingers together in almost a month. LOL

Are there any other airplanes you would recommend for an OS91 FS? Kits...
