N1EDM,

Try camodels.com.ar for the website. It always loads slowly, and I have to hit the reload button most of the time. The videos are great, but take a very long time to download.

CA Models is about to release a 40 sized Epsilon this month, or that is what they told me back in December. Anyway, it is coming soon.

I was thinking of using my Saito 100 in mine, but it has gone elsewhere, hence the OS 91 FX. I think the Saito would work well for this plane in a Sport/3D set up, but would not have quite enough for pure pattern.

Thanks again,
and for anyone else wanting to get there, there's a minor typo in the URL. It should be camodel.com.ar

I'll look at that .40 too, just for grins and giggles. I'd rather have the full-up plane for what I want to do...

Hi,
Anybody use MK bell-crank for Epsilon and which one narrow or wider ?

Thanks,

Dino

HEY MANS

A LOT OF YOU SAID EPSILON IS "PATTERN" ......................

I THINK NO.

EPSILON IS A SPORT OR 3D PLANE, IF YOU LOOK A REALLY PATTERN PLANE IS VERY VERY DIFFERENT, THE FUSELAGE, AILERONS.

PATTERS PLANES ARE HAVE BALLISTICS FLY, BUT EPSILON YOU CUT THE ENGINE IN A DOWN VERTICAL AND THE PLANE STOP, GET DOWN SLOWLY, BUT A "PATTERN" DON´T LOSE THE VELOCITY.

HERE AN ECLIPSE "PATTERN" END EPSILON SPORT OR 3D......

Modern Wide body pattern plane are also designed to have a lot of drag for slower down lines. The Epsilon is a .90 size version of modern pattern planes. Also, since the P-05 schedule has so many difficult maneuvers the ailerons, elevator and rudders on the latest generation of pattern planes have gotten so big that most can do a pretty good job at freestyle aerobatics and 3D. Their tail moments are just a bit too long for the tumbling maneuvers like waterfall though.

Question for any pilots with flying Epsilons with YS110's.:
Do YS 110's require any additional side thrust or is the factory firewall setting appropriate?
If you had to modify / add more side thrust, about how much? Thanks

I think 3drukidding said that 110FZ with a 15x8 APC it was really close or perfect in up/side thrust. If you choose a different prop you will need to change the thrust lines. Look few pages back to see 3d's post on the YS engine and thrust lines.

Thanks. Is the 15x8 about the right prop for this combination (110&Epsilon)?

Ordered mine today

Yes the 15x8 is a very good prop for the Eps/110 combo. It has enough pitch that you have some throttle damping (smooth acceleration) but not so much so the speeds are too high.

I made some modifications on my Epsilon: Plug-in elevator, shorter ailerons, moved landing gear 15mm up and going to use Bolly F3A Large gear, going to use Greve pipe on YS110, made new wingtips.

here is two photos what I've come up so far...

Nice job on elevator. can you explain how you make holes for sleave tubes in elev. halves ?

Thank,
Dino

I sharpened the end of a brass tube and carefully pushed it into styrofoam, making sure it is parallel to hingeline.

VERY NICE JOB,
I THINK THESE MODIFICATIONS IN OUR HOBBY MAKE THE DIFFERENCE BETWEEN A SIMPLE FLYIER AND A VERY GOOD AEROPLANE MODELLING.
THE NEXT THING IS THE PLUG IN WING...........[sm=thumbup.gif][sm=thumbup.gif][sm=thumbup.gif][sm=thumbup.gif][sm=thumbup.gif][sm=thumbup.gif][sm=thumbup.gif][sm=thumbup.gif][sm=thumbup.gif][sm=thumbup.gif][sm=thumbup.gif]

SERGIO

Finally started on mine today - cut out the control surfaces. As mine will be primarily for 3d/freestyle, added on counterbalances to the elevators and rudder. Ailerons cut per the lines, plenty big enough as they are [8D]

Will be intrested to know how that works sprink. I certainly think adding counter balances on elevator will help the 3d. Just been trying to decide on the elevator control. Options are closed loop which I dont like or an MK bellcrank anyone have any preferences. Think mine should be shipping on friday apparently. Cant wait to get stuck in.

Btw. has anyone else had this kind of problems with your kits?... Those lines are the ones that are already printed on the wings... Luckily I noticed this before cutting off the ailerons...

Timbba, now I am worried.

Will check when I get home.

Mattyd, I will be looking at ways of hanging the servos out back, as I will be looking for a rearward CoG. As yet I have not built a tail heavy plane, all have been nose heavy.

Timo,

I got the ARC and had all kinds of problems with it. The wing wouldn't fit on the fuse. Way off. With the dowels in the holes and the front of the wing on the saddle, the back of the wing was almost 1/2 inch above the saddle. The belly pan was not centered on the wing, but off to the side about 5mm. The hard points in the ailerons were not in the same place. One was closer to the hinge line than the other. I wasn't very satisfied with the quality. If it flies well, all will be forgiven. If not...

I also received my kits few days ago. One Epsilon and one Extra 27%. In Extra kit the out corner of one elevator is broken. They use a thin masking tape and was broken by undercarriage i think. The big problem is with Epsilon. One of plywood sheets is made from a very very bad quality ply. Full of cracks and zone where ply thickness is half. This material is not usefully for a package box !!
My importer will change this plate in warranty.

If CA Model monitor this thread i have a question. Why your QA is so deficient ???? maybe you don't saw in production but where you are put in final box or made the nylon package ?

Why you want to ruin your reputation ?

Regards,
Dino

A friend of mine has had his Epsilon ARC since last fall. This week he was flying it and had elevator problems. Luckily he had enough elevator to land without crashing. The ply elevator mount doubler (that raises the elevator servo to clear the rudder servo) came loose. The elevator servo was floating around in the fuse. I had previously removed that piece as I set up my controls differently. I took an exacto knife under one corner and pried up on it. It popped right off. Way to easy. ARC owners may want to check to make sure the elevator servo doubler is attached properly.

That is one of the reasons I want to start building kits. Am sick and tired of shoddy assembly of ARF's. Havent had one yet that I was happy with. And I also have way to much time on my hands at moment.

Timbba, now I am worried.

SPRINK
LOOK THES REAR SERVO

I will be ordering an Epsilon soon and am wondering about the elevator hookup after building a Widebody. I used the MK bellcrank and have a .72 Saito, but the plane is tail heavy. Final CG will probably be around the 38% point unless I add weight.

I am considering using a wooden dowel for the elevators when I build the Epsilon. Similar to the DEPS, I would have 2 control rods on the end of the dowel going out to each elevator. The dowel would slide in a tube to keep it rigid and from vibrating. Does anyone see any problems using this method?

One last question is battery drain from 4 Futaba S3151s. I'll be using a 1100 mah battery pack and have no idea how much time it will give me with the 4 digital servos.
