Viking

Hi,
I just started building a Viking for Old Time Stunt to try out. How much travel do I need on the elevator? And what engine works best on this plane.

The best flying Viking I have seen had a Silver Foxx 40 and about 30 degrees elevator travel up/down. But I don't believe the full 30* was ever used.

I fly a viking in OTS. Its a great flying airplane. I have an OS LA 40 in mine with a ST front needle valve. I probably have around 30 degress of elevator travel each way, maybe a little more. Its a great flying plane. You should like it.

Mine had a K&B 4011 and maybe 30 degrees of travel. Flew fine.

Mine fly's with a Fox 59 most of the time, but I also fly it with a Super Cyke on spark. Around 25 to 30 degrees.

I have used my Viking (CLC kit) for the last 5 years or so with a Fox 36 mkV for an engine swinging a 10x4 APC. There is about 40 degrees of throw in the elevator, but that is too much. Stay with about 30 degrees max throw with full arm movement, a good stiff pushrod and any engine that runs consistently with plenty of power (I like the Foxes, but a 40 sized OS/Tower/K&B engine should do fine as well) and you will have a very fine competitive OTS ship.

I put a OS Max 49 in mine and suspect that it would fly real good if I would ever take it out!

I've been trying to put a picture of my Viking on this post. Just got an new digital camera and trying to figure it out. Here is a picture of my Vik, hopefully it will show up!

Rebuilding mine.....It came out at 24 oz with a Max35s....It's light. Had something go wrong with the paint.

Scott, how many times do I have to tell you?...Latex paint is not really suitable for painting CL models!

I flew a Fox 35-powered Viking for a couple years in OTS. Still have it, but prefer my Zilch X.

The Viking is a good model, remembering we are talking about an Old Crock, after all.

The only problem I had with mine, mostly built from a kit, was in several ribs developing an unsightly "S" curve. Bruce Hunt (Heavy Stunt) used to mock this as being my kept-balsa building technique. Very funny...

When building the Zilch X, which also has pretty long ribs, I under-cut the ribs 1/16" and then applied 1/16" thick x 1/8" wide capstrips. Just looking at model in the pits it looks completely stock, while this definitely would not be the case if capstrips were much wider.

Incidentally, my problems were not caused by silk and dope; Viking was covered in Micafilm and MonoKote.

Mine flies very well with a Fox 35.

I was bothered a little by the thin wing, but there's only one square maneuver in the OTS pattern and I don't turn it so tight I stall it. I built my wing with 3/32" spar webs and 1/16" TE webs.

The stock control geometry will be very sensitive. It's too much for me, so the handle I use for this one looks like a Team Race handle (very narrow spacing).

I like the plane much better now.

Something I learned with my Zilch X was to throw a whole bunch of lead in the nose. I don't actually remember where balance point is now, but it's far forward, obscenely far forward. It would have worked with the Viking, I am sure.

Good catch, Dan.

I forgot to mention that I have three ounces of lead glued to the firewall of my Viking, plus I'm using a Tru Turn metal spinner. And don't be afraid to bolt on that stock muffler.

My Viking is now up to 38 ounces, but flies very well.

Last night I actually measured the balance point on my Fox 35-powered Zilch X (quite similar to the Viking).

I guess the case was overstated in that balance point is not obscenely far forward, but 1.5" back from leading on a 12-inch chord is at the 12 1/2% mark, after all.

It should be noted that I simply gave up on tossing in more lead, due to OTS not being a high-priority event and some other project coming into play. Still, the model is improved over trim seen in 2003 where I managed to reduce David Fitzgerald to saying, "Make ya feel good to beat a Ringmaster?" at that year's NW Regionals. Sorry, it's a bit of an inside joke here in the NW, albeit a very funny one. David and I respect each other. Well, we don't talk about each other behind the other guy's back, even though I just did.

At least a couple flights ought be tried with even more lead stuffed in, although what I'm really fixin' to do is adapt an O.S. small-bore engine to the thing...
