Matt, you can go to Chip's website and download the entire Cap-X manual if you need a reference. I just double checked my manual and Chip is recommending from 3" to 3.5" back from the leading edge AT THE TIP of the wing. I forget what this translates to at the fuse, but it shouldn't be hard to figure out. Have fun.

Would a Saito 182 Twin fly this plane or should I go with the Saito 180 single? I just ordered the plane yesterday and am trying to find an engine.

Hi all.
After reading this thread the CAP-X definately my next plane. I also want to go gas. After some reasearch, I have found a promising company that makes some really nice engines for some short change. They can be found at www.scottellingson.com . They are known as brinelli engines. The performance numbers are right up there and the weight is pretty good too. In a few weeks they are coming out with a 46cc with electronic ignition that weighs under 4lb. That is what I plan on putting into my CAP-X. Hopefully christmas will reveal my CAP under the tree, if not I will get one right after christmas. The engine I will order as soon as it comes out.

This is going to be my first gasser. I want a rocketship.....[sm=lol.gif]

Edit: So I found out I am getting one for x-mas! !!!!!!!!

I purchased one used from a flying pal and have put on a YS140L motor.
We got it tuned in a week or so ago but will most likely not be able to fly it until after
Xmas. Looking forward to see this airplane fly with this engine on it, as he had a Saito 150
and was not to happy with the way it flew. I believe the YS is a stronger motor and it will
fly fine on it.

Ordered mine last friday, should be here by Christmas. really looking forward to another cap. I had Hanger 9's 120 sized cap and loved it! unfortunately it met its demise due to a loose servo extention. If the cap-X performs as well as what I've been reading, I'm sure I'll love it too!

jgraham10, the YS 1.40 should be awesome in this plane. My buddy has a YS 1.40 and says it EASILY out-powers the Saito 1.80. I'm sure you'll be very happy with that combo. I've heard the Saito 1.50 is just not enough for this plane. I have the Extreme Flight Cap (nearly same plane) and I'm still torn between Moki 1.80, Saito 1.80, and OS 1.60. I've read all the threads, but still undecided. I really like the sound of the 4-strokes and have several other planes with them, but wonder if I'll be happy with the Saito 1.80 power in this airframe. It sounds like the OS 1.60 is about ideal, but I'm not sure if I'll like the sound of the 2-stroke. Moki 1.80 sounds like more power than is needed, but balances the plane easier than the others.

If I were to put a ZDZ 40 in this airplane, would I need to move the firewall back any?

Time to bring this thread back to life. Has anyone looked at the Evolution 1.6. ? About the same weight as an OS 1.6 and same output but ina gas not glow?

I Just finished building mine.
Brison 2.4 with abellrc muffler.
DB custom cut 3" ultimate style spinner
NX 20x8
2500MAH ign batt from cheapbatterypacks.com
futaba pcm RX
2500mah RX batt from CBP
Fromeco badger switch
smartfly Equalizer II for elevator servos
5645's on ailerons and elevators with a 5945 on the rudder. choke is manual, throttle is a 9001.
All linkages are centralhobbies carbon rods, with 4-40 dubro HD ball links. Rudder has du-bro HD pull pull.

I started up the motor yesterday. That abellrc exhaust does nothing in the way of making the motor quiet. But man does it sound sweet! It took a lot of strength to hold it back at WOT.

ifixairplanes,

Do you have a weight on yours?

OK. It weighs in at 13lb 15oz

Thats AUW, no fuel. I have somne real beefy batteries, switching to smaller ones will cut my weight down, I must have atleast 1/2 lb in batteries.


can't wait to fly!

Going to set up my throws now....

Hi everybody!

Firstable, thanks for this magnific thread. I have a CAPX and I am thinking about which engine to install. I would like to install a 4T engine, and my decission is between YS160 DZ or a Saito FA220a. What of both do you think will be best suitable for CAPX ? I am afraid with YS so maybe it will be required to add weight in the nose to balance, taking into account that YS weights similar to OS160FX. However, being Saito 220a 45 oz I think that no balance will be required, and 3.5 hp will be awesome for this plane.

Waiting your comments, best regards

Miguel

Miguel, it seems the Saito 2.20 and the YS 1.60 would be way more engine than you need on this plane based solely on experience reported from other pilots. If you want a 4-stroker, I would use a Saito 1.80 and mount the rudder servo near the wing to transfer weight, battery as far forward as possible. Mine is still in the box, but I've studied the experiences of others with this plane (for what it's worth) in order to plan my set-up. Hope this helps, Jeff

Just an update.

I have 8 flights on my capx now and I love it. There were light winds today and I was able to harrier in pretty much one spot in the sky. The brison is a great motor for her. Cruising at half throttle with a little bit of altitude the plane sounds real. The elevator is super effective on the bird. I have 40* of elevator at max throw, and low rates is dialed down to 25%.
Waterfalls are powerful and graceful. Up right spins are just as easy as inverted, and the cap gets really flat too. Knife edge is great, alot of rudder authority. I am still working out the mixing though. I have an always on rudder mix, since the nose down tendency with the rudder is rather strong.

I can't wait until next weekend.......

Just got my Cap X. It has the crazy but neat color scheme. I really was in need of a good beater plane to keep in the car and this fit the bill. Only thing I noticed funky was some of the paint on the cowl and the fit of the H stab could have been better. Nothing an incidence meter and some epoxy can fix.

Since I have read all through this forum I am going to use the CF rod method for the elevators. I will put them and the ailerons in the drill press to get the exact same location for the control horns.

Here is the setup:
JR 9303
R770 RX
2800 mah lion
2 x 625 mgs ailerons (cheap and I have them laying around)
2 x 5945 elevators
1 x 5925 rudder (insane fast)
1 x 81mg throttle
os 1.60 with pitts

Nothing fancy and looks like it will make a great basher plane to keep in the car. I am going to put some pin up girls in the white areas of the wings and stabs.

Should be fun to fly with an insane fast rudder. Going to try a VP 20 for the OS 1.60 as I have used it in the past. Right now its my only glow engine and I plan to keep it that way. Why glow? Well I want to keep it inside the car and not have the to worry about gas smell. The scheme is really growing on me the more I look at it.

I have been skimming through this thread and dont see much on the Saito 220... Are there any reports on how well or not well it did?
The plane is on the way engine in the shop.......

Well I finally got the airplane madiened this week and flew it agian today.
It is very responsive and fun to fly.
The friend that I bought it from maidened it and his comments were that it flew better with the YS140L than with the Saito180.
So far I have around 5 flights on it and hopefully I will get a few more this weekend if the weather will allow it.
He modified the airplane so that the elevator servos are inside the fuse and CF rods run to them.
I thinks this will be a very nice addition to the hanger.
It lands very nice and smooth.

Hi all,

I'm building a CapX again. It's the new paint scheme now and will go back to my favorite engine, the Moki... but this time I'm going with a new Moki 1.35 to see how that does. In my old CapX the Moki 1.80 would do almost unlimited vertical with a Bambula 18x10 and I though way over powered. This new paint scheme is a little wild for me so I found a NIB CapX in the older Red, Blue and White version and have that also. Guess the build of the older paint scheme will come later in the summer but I'll go back to the Moki 1.80 on that. Between these two CapX's I have to try and finish the Giant U-Can-Do and my old vintage 1985 Sig Clipped Wing 1/4 scale Cub. I'll be busy this summer.

Glad to see you guys have this thread back up and running on Chip's CapX. It's one of the best flying planes I have ever had and I say that with some experience as I flew my first RC in very early 1960. So been around a time or two. I'll post some images of my build as I get into it, and be glad to pass along any information I have gleaned from the first build if it's needed.

Ragards,

Ok, the Cap X is almost ready, O.S. 160FX with perry pump, Hitec standard servos all around, onboard glow starter up front ect...ect... Seem I've got a problem though, I've noticed that the "H" stab is not quite parallel with the wing, approx. 1/16". I used CA to glue it in, but feel I should try to fix it before my first flight. will a good debonder soften the CA enough to reset the stabilizer?

Well I like this plane more and more each time I take it out to fly. Got four more flights on it today and five or six flights last saturday. The 140 really seems to fly this airplane with no problems.
Landing is a breeze as it just floats right in. The comment from my friend is that this plane is making me a better pilot and I feel that is true as I feel more comfortable flying this airplane. Will be
recovering it as the covering is starting to come off in a number of areas but that is to be expected with how many flights this airframe actually has on it.
John

If anyone is still following this thread, can you answer a couple of questions for me? I recently purchased a new Cap X on sale for $249. It's the one with the wild color scheme. Did your arf come with a motor mount? My manual says it is included, but it isn't and the firewall is predrilled. Also did yours come with any wheels or tail landing gear? Thanks for any response.

I have the older verson, yes it did come with a motor mount and hardware but you need to supply the wheels, tail gear and such. Maybe the new ones don't come with the motor mount. You should email Chip at his web site and ask him.

good to see this thread running!

I am just now getting to get ready for this seasons flying...I know..tell me about being late!

I am dusting off the ol CAP-X and was considering swapping my PITA OS 160fx for my YS 140 that has been refurbed from YS and needs a home.

I also wanted to ask you all what the CG is from the LE? The whole TE thing throws me off every time. Just wanted to re-cg it before I fly it again

thanks

matt

The recomended CG is 3" to 3.5" back from the LE at the TIP. Not the TE. I don't know what it is at the root of the wings.

Thanks Flyboy for your response. I had already emailed Chip but no response yet. It looks like my plane was started and then returned by someone because the firewall was permantly installed. I guess they figure you don't deserve much for $250, however I had a CMP Katana (same size) with a lot better covering and it was only $220.
