thanks for the info. Can you post some pictures of your linkage set-up with the arrow shafts?

on second thoughts:
11.5mm seems like a lot, and 19/64" is about 7.54mm. There's quite a difference, can you check on that?
Thanks,

Alejandro

You are right and I somehow wrote down the wrong measurements in metric. It is as you pointed out, 7.5mm. I don't have calipers yet, so this is against a metric ruler. Thanks for catching that. The standard measurement is correct.

Here is a pic. You can see a piece of the rod as it comes out of a hole to pin the rod securely down inside the shaft.

that's an interesting solution. Is that a hard wood dowel coming out of the end of the shaft?
Thanks for the pic.

Status: offline 		Yes, and it is a slightly snug fit. I used a good bit of thick CA into the shaft before shoving the dowel in place. The hook holds in place on it's own while I'm doing this.

I made a double rod shaft for the elevators today. I cut two grooves on the outside of the dowel for each rod to rest against the dowel and inner wall of the shaft. I bent each rod over plans that I made on graph paper for the actual size from the rod in the fuselage to the control horn on the elevators. They came out dead on with the plan, so I'm doing the final installation of this tonight. I made a small ply piece glued between the fus sides and former F6. A lightening hole looks like a diagonal cut on the piece, but it goes all the way across top and bottom. I left some dowel exposed to give the correct spread to the rods. The last thing I need to do is wrap this section with thread and harden it with CA. You can see another hole for the rudder rod.

Status: offline 		Blw, you probably already know this, but for others who might see this and want to try it, I will just say that while you have your fuselage open, you ought to take some measure to restrict the side-to-side movement of your elevator pushrod. I notice the guide hole is a loose fit around the pushrod. If the pushrod is free to flop from one side to another, it can impart significant differential between the two elevator halves.

I have sometimes used a couple of pieces of balsa snugged up (not tight, just snug) to the sides of the pushrod, then CA'ed them to the former. If you cut a diagonal corner in each piece to let the pushrod ride in, that works well enough. On other occasions I have used a couple pieces of foam rubber laid up against the sides of the pushrod, and gooped them to the former. It doesn't take a lot of pressure to stabilize the sideways movement, and the foam rubber presents very little friction on the pushrod.

If you link up your elevator halves with the fuselage open, then just move the pushrod from side to side with your finger, you'll see a significant differential movement in your elevators.

Status: offline 		I have some rubber grommets that may fit in the holes. If not, I'll cut some balsa with the centers cut out for the rods. I also put in plastic guides after the photo to run to the exit holes in the fuselage.

thanks for the pics. I think i will get some carbon rods and build my own DEPS system for the epsilon.
I would appreciate if you keep posting pics of the building process as you go.

Sure, but I'm almost done with the plane. I wasn't really able to take pics when I first started the kit. I hope to fly mine before Christmas. Good luck on yours. How far along are you now?

let me know how it goes when you get to fly yours.
Mine is still in the box, will have to wait until next year to start building.

For those that need a push the epsilon is my favorite and best performing plane.
It'll do practically anything you want to given a bit of set up time. With out doubt the right choice of engine is the YS. I started with an OS91FX and it was good ... I then changed to the 110 and yikes its awsome ... stump pulling ... just haven't quite had the confidence to hand launch it but I'm sure it would go

Go for it all and enjoy this is one hell of a good plane.

With regards to the YS fitting ... and it does . If you use the MK beam mout on a standard T bar engine mount it bolts straight in where the 91 came out. I did do a bit of reinforcing with carbon on the back of the firewall but that was all ohh and put the tank on the CoG ... no trim change fantastic ... and you can tell it when you have a 14oz tank in.

I'm sure there are many ready to fly 90 size models out there that equate to the epsilon now ... but you can never beat the fealing of having your own creation fly a smooth sequence knowing and understanding what keeps it there.

Happy new year all
