Thanks for the reply! The canopy attachment is now good, I think. By the screwed it is hold securely.

Guys just wondering is anyone using much or any Aileron Differential on the Episode. Finding it difficult to get the roll completely axial!

If your having a lot of issues getting it to roll axially, install another, larger set of stab fences along with what you already have. That will lock the tail in better and help with the rolls. Also, accurately measure the throws of the ailerons with something that can get you measurements within about .1 degree. I use pointers and a homemade protractor. But each aileron must be throwing the same. Then you can dial in the differential with the radio system.

Another way of checking if you have sufficient yaw stability is the spin entry. If it tends to drop a wing before you're ready to enter, then you need the larger stab fences.

Also, be wary of the extremely effective rudder. It took me awhile to get used to that. I had problems with rolling axially initially and found that it was due to me just using inputs like I had been doing for years with other planes. Back your rudder throws way down for normal flight.

I agree with Steve. Rolling through knife edge, many times you don't need to add rudder due to the large fuse area. Many times, we add inputs when the plane doesn't need them.

Thanks for the Input guys and ye highlighted all my issues so its me and the plane. Yes i am adding in to much rudder so i need to cut that out. Yes Tony is does seem to drop a wing when entering a stall so i might go ahead and try the second set of stab fences.

I will also go over my throws and make sure they are equal throughout!

Thanks for the help lads. Will keep ye informed.

Hi mikey, check the lateral balance also.

Lateral Balance is prefect thanks Paul. Not sure what colour to cover the Stab fences.

Very interested in the connection between yaw stability and dropping a wing on spin entry Tony, care to elaborate?

If the plane is not yaw stable, then as it slows down it will yaw one way or the other. That yaw will cause the spin break to be unreliable and instead of just the nose dropping straight ahead, a wing will drop with the nose. Especially in upright spins. Inverted spins will probably be cleaner as the fin is not blanked as much.

My original Episode even with the fences I have on it is that way. On the new one I made the fences slightly larger. Now it is very reliable on spin entry.

Thanks Tony for the explanation. I noticed that when I added the second set of fences that spins in calm conditions became more predictable, but I wasn't sure of what the actual relationship was. That makes perfect sense.

I have added fences on the wing to get the same effect as bigger fences on the tail. It stall better into spins( was dropping wing) and is more stable for slower landing.

Thanks for that Tony,

Have you tried any other vertical surface increasing devices on the rear of the plane? I'm thinking winglets or small additional mid span fins that have been added to some full size aircraft with yaw stability problems. Float equipped DH Beaver and Fairey Gannet contra equipped spring to mind. Trying to decide best way of improving the yaw stability of my Contra equipped Asyuler. Temporary fences seem to have helped but was just wondering if there is a better way?

Guys has anyone tried Turbulators on the wing tips? I think i might make up some strips and see how i get on before i go adding to the Stabs. I flew the new Eflite Carbon Cub recently with QQ's designed Turbulators. wow do they make a difference at slow speed.

I agree with Tony on the stab fences. On mine, I only have one set and the stall break is textbook straight as can be, but I run the Contra. I am debating whether to add a second set to eliminate the aileron differential required (I currently use -5% diff), because without it the plane was rolling "under itself" in the verticals. Rolls nicely now, and haven't noticed any secondary negative effects of the aileron diff anywhere else in the pattern.

I had 6 flights today with -5% differential and it has made such a difference in rolling combinations. Very happy now. Thanks for input John.

Sorry Paul, forgot to check my C.G location but will during the week

Hello guys. I started flying pattern back in 1979. 1st Nats in 1980 last one in 1995 in Tex. I stopped flying in 1995 to take a couple of year off. Well its been 19 years and its good to be back. Everyone at the flying field was flying 3D stuff, so I bought a little foam plane that could do 3D and was just not happy. Luckily a flyer showed up with a 60 size pattern plane and let me fly it. That it. Pattern is what make me happy.

So here is my new plane Episode painted up in the same colors as my EU1 build from planes out of "Flying Models." back in 1980

It should be flying next weekend.

Hope to be out there soon on the contest circuit.

Good for you Richard. The episode sure looks different in those colours. I am sure you will love it's flying characteristics.

Blake, is -5% differential more down aileron throw than up? Or vice versa?

thx

More up Aileron then down but i basically reduced the amount of down Aileron so thats why its -5%. It has made a difference for me anyway.

I use a JR XG11 and the differential is opposite. -5 is more down than up
