Low flying aircraft over 4th celebration

Post  RknRusty on Sat Jul 05, 2014 9:13 pm

Last night I was preflighting the Skyray for today's cookout/funfly with my RC club at Fort Jackson. I was not really looking forward to being the only control liner out there. For one thing, I'm more that a month out of practice, my last flight being June 1st. Plus when I fly, the RC guys all land to clear the runway, so all eyes would be on me. But as I tinkered and tuned, the spirit began to return and eventually I had a full fledged case of the flying jones. Not only that, but this was to be a FUN fly, so by god I was going to have fun and that meant taking more than one ugly old stunt trainer. So I'm looking at my fleet. My beloved Shoestring. My big ol' Magnum. My red and white Russian warbird... Ding! The Yak. But I gave my fuel tank to Matt for his Ringmaster. Hell it didn't hold enough fuel anyway. I had the old 4oz uniflow wedge tank I cannibalized off the Clownlikething. I washed the green out of it with some alcohol and mounted it up, and it fit like it was made for the job, much tighter and less prone to shifting around. Feed tube on the bottom too with a short run to the engine. This is looking good.

So this morning Holley and I loaded the planes, coolers and gear in the car and headed out. Got to the field early and the American flag and windsock were sticking straight out in a mean wind blowing through the trees and straight across the runway. The forecast was for declining wind as the day got later, so I ran my lines out and waited. None of the RC guys would try, but I was determined to fly. I decided to just take 10/22 fuel and try that in the Fox on the Yak, so I gave the engine a run to get the needle set. That proved to be harder than it sounds, but I finally got it breaking pretty well and parked it until the wind hopefully slacked up. But I'll fly the Ray in a gale with no worries. I recruited a helper and put it up for a flight. It fluttered like a bird on the upwind side, but the wind was steady, not changing directions, so it was easy to pick the right spots and I managed to knock out a full pattern. I had to try twice to get the cloverleaf but not bad for a first flight. After a break I did one more before we cooked lunch on the grill. It was a BYOM, so we had everything from brats and dogs to chicken and steak all cooking at once.

The wind was a little better after lunch so I rigged up the Yak and took to the field. I had it set standard vented so it started a tad too rich barely breaking 2 in the wingover, but just good enough to do it. I wasn't wild enough to try a lot of stunts at first, but as I flew there was none of the coughing out I had experienced with the other tank and it would do 3 insides and 3 outsides slick as owlshit. About 6 laps inverted and a single figure 8, some more loops and wingovers later and it was cruising lean and hauling ass around the circle. By far the longest flight I've done with this plane. It ain't much for pretty round loops and stuff but it will turn on a dime and go wherever I point it. I can see why it's used so much for slow combat. It actually reminded me of a Flite Streak the way it'll turn a stupid sharp corner. Still wary of the wind, but this was the first time I've really had a chance to just have fun flying the Yak. Pretty cool. When it finally ran out of gas I did what I'm pretty sure is the ugliest landing ever, but when it stopped, it was still wheels down, so we'll call that a good one.

And later we got to see some good heli action, a 1/4 scale Extra, assorted warbirds and fan jets, did a couple more Skyray flights, another Yak flight and called it a great day.
Happy 4th everybody.
Rusty





My new tank. Works marvelously!

Glad that tank woke the old Fox up. If you install a ST needle or better yet a PA needle you will be even happier with the run. Set it up and leave it alone all day.

I have ST's on my Fox .40's and my Silver Foxx .35

For my other .35's I used the newer Fox needle and it too is a set and forget.

Fox new style

I want to do that. I don't like the flat needle Fox style. Which ST engine do I buy the needle for? That's what my Thunder Tiger has, a ST needle but it's a sprinkler setup.

Looks like Super Tigre .51

RSM has it for $9.99

The PA needle is supposedly better, but I have not tried it. For $18.95 it had better be!

Thanks, I'll put that on my wish list. Super Tigre .51 from RSM, $9.99.

I think I'll take it out Thursday and maybe compare fuels just to see the difference in performance. I had to set the needle several turns leaner with the 10/22 from where it had been set for the 5/29. I hope we can get a day without so much wind so I can concentrate on my shapes rather than survival.

Bob Zambelli will be flying with us on Thursday. Don't know if any of you guys might know him. He was a great judge when I flew in the profile contest in May. He came over and gathered the pilots and discussed some things he saw us all doing that needed improvement. I appreciated that.

Here are a couple of pics Holley took with her phone. You might need a big screen to have a decent look.

Yak-9 in flight.

Bob was our club president for years.  I truly enjoy talking to him. Bob's knowledge of engines and his building skills are over the top. Bob is also a exotic car collector. I don't know if you saw him pull up last year in his vintage Ferrari at Huntersville. Please tell him Ken and Shawn said hello. He stayed briefly last year and I was only able to shake his hand before he left. Bob's Stunt Rocket is the box picture on Larry Rice's (Blackhawk Models) kit. I know you were fond of that model. If you want to see a Fox.35 run like no other Fox you ever witnessed, check out Bob's stuff. He's helped myself and others achieve runs from these engines that most can't believe. We like to say were just finishing the steps that Fox didn't want to do. As to your needle question. I would contact Eric Rule and find out if the spraybar he's selling on that link has the spraybar turned down to the same diameter as the stock Fox unit. If not, your Fox will be down on power. A stock Super Tiger spraybar is considerable wider in diameter taken up choke area. Just because it says it fits, it doesn't mean it's the correct diameter. A Randy Smith unit is the correct diameter and it's a superior needle to everyone available on the market. Tiger needle are ok, they're not totally leak free. This is why Randy provides a Teflon collet washer under the jam nut. Randy's spraybars and needle are stainless steel but they're also double the money. If that particular needle is sized correctly, I wouldn't hesitate to try it. I see he has nylon shim spacers in the picture which would allow you to center the hole properly on the spraybar. This isn't the case using a genuine ST spraybar. Bob Zambelli will tell you his success is the Enya unit. Keeping the needle as short as possible is also key to a good run. The Fox can resonate a long needle valve which will wear out the threads inside the spraybar causing even further issues which will drive one crazy. Ken

Okay Ken, I'll be sure to say Hi to Bob for you guys. So it sounds like I picked a good day to experiment with the Yak, so I'll make even extra sure I'm prepared and I'll try to act smart too Lol.

Bob struck me as a character the first time I met him. All us pilots were goofing around before the profile contest and he came up and walked the line of planes making sure they were all numbered properly. A minute later he shouts, "Gentlemen, the pull test is on the honor system here. Here's the scale, NOW DO IT!" We did. Then I recalled having had a 10 minute conversation with this guy a while ago talking about engines. Boy, you just never know who you might be talking to.

Since the stunts were on the pit side of the field yesterday and we had RC activity on the runway, I didn't bother with the camera and tripod as that would have added a lot of extra walking. Plus all of my flights were in wind survival mode which is never pretty. But I'll try to get some video Thursday.

Rusty

Yeah Kim, they are a great group. They are accepting of me using the runway and are mostly fascinated with control line. We jab good natured insults back and forth. I accuse them of yawning while flying. Two people told me yesterday they had never seen one fly before. And one guy had never heard of it and I had to show and tell how the plane worked. I knocked out some stunts that were flawed by CLPA standards, but must have been pretty exciting for them to watch. The Vertical 8 is by far my best trick so I included some extras. I could hear the crowd shriek once when I pulled out at about a foot high. One of those times when the wind takes the lift off of your wing. Scared me too, but it was seamless and I kept flying as if it was all good. The squares gave me the most trouble in the wind. Probably because I still bang the corners too hard and bleed off too much energy.

Rusty

Rusty, Bob has run several events at Brodak's throughout the years. Bob is very safety orientated. He writes the safety columns in Stunt News and also in Brodak's Control line World. I hope he brings his V-tail Stinger. I believe this was a Dale Kirn model. I remember years back when Dale called Bob in regards to this model he built. Good luck and most of all have fun. I wish I could be there. Ken

Thursday looks good for the fort. For the Yak-9 I'll take some 5/29 Fox snot and see if that gives the Fox a better break for more of the flight than I got Saturday. Though it never burped on the 10/22, it was too rich for the first few laps, then just right, but soon it was too lean with a lot of flight time left. But it drank every drop. But before I switch fuel, I'll set it for uniflow and see how it likes the 10/22. That's my secondary mission. My primary mission is with the Skyray, to fly the pattern with these guys, watch, listen, and learn. I think I'm a slow learner. It's a great opportunity to fly with someone like Bob and I want to make it count.

The Yak looks like a prime candidate for electrickery. The extended nose looks like it has plenty of room for an ESC and a timer.

I like those Fox engines - I can see why they have drawn such affection amongst you chaps - rather like the British and PAWs. The 35s are absent from my collection (so far!) and I don't even remember see any over here in the 60s or early 70s.

I have the Skyray kit - not really started yet as I have been using it as a basis for learning CAD/CAM wing design (How to cheat and get a machine to cut ribs for me!). I have an OS motor (motor, not engine!) lined up for it but I also have a PAW 35 (decisions, decisions).

Good observation, Ian, regarding the Yak. I would almost be willing to bet such a conversion has never been done being that it's such an old model. After watching Wayne go electric, I've become more accepting of the idea and impressed with the power systems. Then again the idea of an electric Yak-9 reminds me of the signature of one of the Stunthangar guys that says,
"Electric is the future of Old Time Stunt." lol! 

I would never be using a Fox if Ron hadn't set me up with the old Sterling kit and included the engine. I'd never even seen a 35 size engine up close before and was a little intimidated by it. But once I saw it in action I understood the attraction. The authoritative sound it emits is as thrilling as a Harley Davidson on an open highway. However I do recommend a laminated fuselage when using one. After a couple of flights the Yak had spiderweb cracks on the inboard side, wing filet and stab. They are fine after filling with CA but if not for the epoxy core, the fuse might now have been shot.
