My tank was not as pictured either.

I used a two line system with a Slimline Ultra Fueler:
One line goes from the clunk to the Ultra Fueler then to the Carb. The second line goes from the top of the tank (bend in tubing) to the muffler pressure tap.
Both lines came thru the stopper.

The tank I received had a nipple at the bottom of the tank. If you use a three line system ( one for fueling/defueling) this nipple could be used. Mine was not open and would need to be punched out if used.

The screw hole you referred to I believe is the hole used to keep the stopper in. A screw should be supplied for this.

I went into detail not knowing your level of building experience.

There are several ways to setup a fuel system ... fuel dots, Fill Valves, etc..

I stay away from spring loaded fuel valves. I was advised by club members that have used them .... vibrations cause the spring to fail ( then leak), and then flame-outs have been encountered on takeoff etc..

Hope this helps ... others may have more ideas/suggestions for you.

I've gotten to where I use a 3-line setup almost exclusively, eliminating alot of the BS of fuelers, removing carb lines, pinching carb lines, etc...

For three lines I setup a vent tube bent to point toward the top of the tank. I setup up the clunk line as usual. I setup up the fill line like an extra clunk line, but do not use a clunk on it. I bend the tube behind the stopper on the fill line toward the bottom of the tank at about 45 degrees and put a peice of fuel tubing on it that reaches the rear of the tank. The slight bend in the fill tube biases the fill fuel tubing to the bottom of the tank and ensure that I will always completely empty the tank. The stock CapX tank has a fill/empty nipple molded in that could be opened and used, but you would have to make sure the plane is nose down to empty it completley. The stock CapX tank also has a nicley placed vent nipple. So here's how I'd do it if i were using the stock tank. Use the two open holes in the stopper for the clunk and fill/empty lines and use the molded vent nipple for the vent.

Sorry I rambled a litte, hope it's helpful...

Drilling the firewall for the Moki 1.8 was simple. I just drilled it out in my family room while watching TV.

BTW - the 1184 muffler does NOT fit. Looks like I'll have to switch it for the 1180.

I've started assembly of my Cap-X and I have a question .

Anyone know what the 4 black plastic L brackets are use
for ? Looked through the manual but found no reference
to these parts! There in a bag with some screws, and
nothing else.

Since it's been reported that the plane comes out tail heavy
with the OS Max 160, I plan to installed the elevators servos
under the canopy with a pull-pull system like my DP Extra.
I won't need any nose weight with this setup.

I would like to see this plane RTF weight under 12 lbs. Then
it will really perform well with OS-160!

Stick,

I could not figure out the L brackets either. I can't see were the plane needs them.... I think you have a great plan with the pull pull elevator. I had that plan when I started on this plane but I got lazy and put the servos in the tail! Even with the servos back there and the added lead it was still just about 11 3/4 lbs. The OS has great power on this plane, but yours will be even better. Depending on battery selection and a few other things it should be right around 11 1/4 lbs. Good luck

Stick2000,

I also never figured out what the plastic L's were for. I started to glue them to the inside of the cowl as stops after the cowl had been mounted to help get the cowl positioned correctly when re-installing it, but didn't.

If you get this thing to 11-1/4 by moving the servos it will be one ssshweeeet machine..

Drew - Sorry to hear the 1184 muffler for the Moki does not work....[]...now I feel bad for suggesting it....[][]

Hi guys,

Could anyone tell me the fuel economy of OS 1.60 and Saito 1.80. I've heard they are terrible on fuel but it seems no one metioned how bad. I am considering to buy the CAP-X in May and it would be helpful to decide what engine to use.

Thanks

Well, the saito is a gas hog. from what I hear, the os is pretty good on fuel. I'll find ort pretty soon though, I have the os for my cap.

Jinwoo,

I have had both and I can tell you the OS 1.60 uses quite a bit less fuel than the saito 180. I really don't have definate fuel consumption numbers for you, but I would guess the saito uses about 25% more. I am not sure what size tank this plane comes with, but I can fly for about 10 minutes and land with at least 1/4 tank left with my OS. Hope this helps.

If people who have owned both say so then I guess the Saito may use more fuel than the OS 160. However I have owned an OS 90fx and several saito 91s and the saitos used less fuel and were much more fun to fly. The oil mess was about the same. However I would still prefer the sound and rapid, high torque throttle response that you get from a 4 cycle than the spool time of the 2 cycle. I am sure many will disagree with me but thats my opinion. And I vote with my wallet.

I have never owned an OS 160 but I had a Saito 180 and it used a lot more fuel than even my Moki 2.10.

I am looking for the titanium turnbuckle type push rod's. Anyone know who manufactures and or sells them?

I flew one I setup as a test bed for a small gas engine -
the all up weight was exactly - 12.75 lbs
The little gasser turned 7000 on a 18x8 Bambula - so the plane flew very nicely ---BUT not near enough power to suite me .
This is a very nice ARF- I soldered all of the control horns and redrilled the bushings to .0625 and used all 2/56 control linkage - JR 811s on th elevators -a 8411 SAon the rudder and early JR digitals inth wings
the linkage is plenty strong
and the control is very precise
With a ZDZ40 -or any 40 that is good -this will be a dynamite ARF
The engine I tested weighed more than the ZDZ40 . it also had much less power as it was only about 1.8 cu in. very smooth - just -no poop.
balance was in the center of the bottom white stripe on the wing - behind the blue LE area.
I tried the Harrier stuff - very good - but power maneuvers were out - the waterfalls pooped out and barely made it back to level -
Nice plane.

Was the above mentioned 1.80 engine an RCS 180?

All,
I am finishing up the pull-pull system on my Cap. Does anyone know if they make some type of plastic liner to glue into the area where the cables exit the fuse?

I used the Dubro pull-pull guides on mine. Just got back from the Toledo show and got notice my Brison shipped on Sat. Should be here on Tuesday, Wednesday at the latest. Now all I need is a muffler. Even more interesting is the other Brison I had on order is in too. Now I need another plane!! I picked up the hardware to build carbon fiber pushrods for the Cap at the show, and picked up a set of Carbon Fiber landing gear from TNT as well. Don't know if I will really save any weight with the landing gear or not but they should do wonders for the look of the plane.

How much was the landing gear? When I asked them if they had a set for the Cap-X they said no...

NOVAflyer, they were $50.00. I borrowed a set of gear from Planes plus and took them over to the TNT booth to compare with what they had on the table. The pair I got is the correct height and width, and fit the saddle area correctly. They are 1.5" wider (wheel spacing) then the original, but that should just make the plane more stable on the ground and help a little in the air as well by ensuring the wheels are not in the prop wash.

All,
I am installing the fuel tank on my Cap and
I noticed in the photgraphs that are posted that the fuel tanks appear to be mounted further back (toward the tail) than shown in the instructions. Was this intentional due to balancing demands or is this just because of a bigger tank?

Appreciate the help.

I'm pulling mine back to center the fuel tank over the CG - that way the CG does not shift as the fuel level drops.

Same here. It's done so the CG doesn't change in flight. The caveat is that you have to have some means to get the fuel to the motor from this location. That means a pump, a regulator, a header tank, or anti-gravity fuel lines....

Richard

True enough, but nuttin special needed in the way of a pump if you go with a good 4 stroke or a gasser!

When flying my Cap x, I have noticed that I need a lot more right thrust than what is built into the firewall. Has anyone else had this problem with their planes? When verticle mine pulls hard left.

Made the first flight today. Should say half a flight. Deadstick. New engine, (DA 50), INEXPERIENCED gas user. Never got over half throttle, but this plane flys so good and is so stable. CG was slightly nose heavy, dual rates never made it to high. Earlier, I had slowed it down to check the stall and it just mushed forward with no sign of tip stall. The deadstick was very uneventful. I wish I could land that good every time. The only problem was some covering coming off. I failed to seal all the edges. Overall, I would give it 4 3/4 stars out of 5. It needs more than 5% up elevator in knifeedge though as it wants to go toward the wheels. Thanks Chip, you did good!!!!!!!!!!!! Dale
