I talked with Windy on Friday and the Strega's are in. Mine is on the way. How much i don't know, i was on his list and the bill is with the plane. I believe Brodak now has some and it will be quite a while before the next batch reaches the USA. I am sure more info can be gotten by calling Brodak, Windy or maybe even Bob Z. Ron.

Hi Ron,

What power train are you going to use? Since Kent Tysor has been fly his Strega for quite a while now (three different ones, IIRC) I have seen it under go "system" changes. ST 60 to Ro-Jett 76/pipe.

peabody · « **Reply #2 on:** December 18, 2006, 04:18:58 PM »

I believe that Strega ARFs from Winfred are $149.95 plus $30.00 shipping...send him a check,,,the supply is limited.
Around these parts one of the prototypes has around 100 flights on it....and the committee encountered a few trim issues....but resolved them.
Windy built his in a day....powered by an RO .76. He flew it twice today and says that he has to do some work with a prop....
That's my story and I'm sticking to it....

Ron Merrill · « **Reply #3 on:** December 19, 2006, 08:56:39 AM »

Bill, will use a GMA/Jett .60se to start and see what happens. I am waiting to here from Windy on his testing. It will be on DVD if anyone is interested. Peabody i like your story and i will stick with it two. Sure hope to see more feedback on how it does, then i can just follow the bounceing ball. Ron

Not only 60 sq. in. more but those square inches are very thick, too.

I think the wing is about 3 inches thick at the root.

Well Willis, one solution would be for you to buy a Saito 62 or 72....

I can give you the new K&B 61 ABC I got off of Tate as well. Its not like I've done anything with it....

I bet the K&B would pull the Strega fine, and you KNOW Tate wants to order one!!!!!!!!

My Strega order showed up today, man did Brodak get it right. The controls are fantastic and even the hinge slots are inset. This is not your average ARF, these things with proper power can be competitive at any level right out of the box.

Got mine today, everything is great but the covering job on the fus could have been a little better, oh well it's better than what I've done. In the supplimental instr. I see they advise spraying Lustre Kote clear on the covering joints to keep from coming loose. Very nice ARF

These critters come in BIG boxes....I got two ARCs yesterday and the package could have been a coffin for my second ex wife! Lots of care that UPS doesn't mangle them....

I also watched the Windy video last night....it's very informative and lots/most of the information is applicable to all ARFs.

There are some terrific features here....certainly worth the price...and there a few things that I plan to change....all in all, it appears to be the best of the bunch....

I didn't see anything in the ARC I examined that needed changing other than replacing the hinges and maybe whatever it takes to install the engine. Oh ya, looks like the nose ring needs to be cut off and attached to the cowl so you can get a 6 1/2 ounce tank in from the front.

That is funny.. I didn't look at the instructions and one of our club members (Tom Martin) came up with the idea of cutting the nose ring in half and attaching it to the cowl.

We should have two flying fairly shortly, one with an RO Jett 61 and one with a ST 60. The ST 60 one (Joe Gilbert) will be in the air first, Tom Martins (RO Jett) may take a while.

Just finished looking at the two DVD's Windy sent me. Changes Windy made or reccomends are radius l/e,use cf tow on ball links and epoxy top and bottom nuts on bellcrank,motor offset 5/16",replace flaps with 1/4" 4lb. stock flat sheet/radiused edges, Rabe rudder (personal choice), tape all hinge lines. he is using RO/Jett RE .76/ 14x5 Rev-Up, 68',.018's. He says front lead out runs when l/o's to far back. If possible remove peice it rubs on (ARC). Need 1/2" longer gear when using 14" prop. Windy has got the weight down from 65oz. to 62oz., he now is using one of his CF spinners. Hope this helps, i am getting more DVD's as they become available. I will be happy to share them. Ron

SORRY meant to say elevators with 1/4" not flaps, and word is rub not runs on lead outs.

I received my ARC Strega Yesterday Its a big airplane at least too me. Steve Fitton was nice enough to lend me a Brodak K&B 61 to use which I have started to mount with aluminum plates. There is a few holes that I plain to close up one for the tank to slide through and one in the cowl, if not the fuselage will fill up with oil. My biggest problem before I go any farther is what color do I want ? The mail system did a number on the out side box lucky they pack it as good as they did No damage to the air plane itself. Any one know how much fuel the ABC K&B uses for the pattern?

There have been a few asked and sent emails to me about the RE set up for the Strega. Previous post was showing the plane and engine after completion. I have been asked if the header muffler is just a header with a plug in the back. It is not and I am posting the pics of how I build one. I make the internals based on the engine size since all of the engines from 51 to 76 are in the same case basically (the 76 and 67 are taller only) and I use the same header for all of them. I have a special header made that is a larger diameter, 7/8 OD. I then cnc the internals and construct the header muffler. If someone has special needs and I need to alter the bends I can also do that within reason. I can make a 45° bend in the back end so that an exhaust diverter is not needed. I just sent one to Windy to test in his Strega. I have made several for Windy to test and rest assure they will work in the Strega or Windy will not sign off on them nor will I. I am testing them as well in my ARF Strega. We are working to have a turn key set up for you guys. I am also testing side exhaust and feel it is just as good but not for end of the day clean up. My header/muffler will also fit a PA 51, 61, 65 and I am not sure about the 75. Randy has a header muffler as well but I have no test data on it and neither does Windy.

The pic of the internals show two incerts. Small one is for a 40/51 and the large one is for the 67/76

What's the preferred tank set up in this bird. The Brodak kit mentions the BH-563 tank; Wide Wedge Uniflow (All Tubes Forward) as a 6 oz. solution. 1"H x 2"W x 6" L. If there is room perhaps the BH-564 (6.5 oz's) or BH-565 (7 oz.) tanks might be made to work. These each increase in length by 1/2 inch to 6.5' and 7" inches respectively. Power choice for mine will be ST-60. Comments?

Ralph Wenzel (d) · « **Reply #50 on:** January 08, 2007, 04:21:11 PM »

The tank compartment in the Strega is 1¼" tall and 2½" wide. 6½" is about the max length of the tank with "random" all-forward-facing tubing. A tank built for a specific engine with tubing routed for clearance could probably be 7" long, maybe 7¼" (this would be a real squeeze).

peabody · « **Reply #51 on:** January 08, 2007, 07:20:21 PM »

I believe that Brodak amkes the "Magnum" tank in 6 1/2 and 7 ounce flavors...just the feed tube exits to the front.
The uniflow and vent exit down then loop up to above top of tank....

Ron Merrill · « **Reply #52 on:** January 09, 2007, 02:03:58 PM »

RO, show pictures of the header/muffler you made for Windy to test with the bend to clear the bottom of the Strega ARF. It really is a nice clean setup for the .76re.

Richard Oliver · « **Reply #53 on:** January 13, 2007, 04:18:53 PM »

I made this for Windy to test this week. The thought is to do away with the exhaust diverter(.5 ounce) and the cost. We will be testing more soon but Windy's weather is going away and he might not get back out for a while.

Just thinking out loud here. Re: Wing leading edge profile. Has anyone contacted John Brodak about their findings regarding the sharp leading edge issue? Is it possible they might update the production runs to include the rounded leading edge on later runs of the ARF Strega kits? This may have already been put into the works perhaps seeing as Windy has helped develope the product by some degree. (A large degree I'd guess).

Also, thanks for the tank info. I'd all put forgotten about the Magnuim style tanks. They may be just the ticket to get the max. fuel on board.

Walter Hicks · « **Reply #56 on:** January 15, 2007, 08:58:50 PM »

Hi Everyojne,

I had my maided flights yesterday with the ARF Strega. Set up as follows:Clamp mounts for

RO Jett .76 Se with RO Jett Muffler, Rev Up 14x6 prop. 6 oz metal unfilow tank no muffler pressure.

1 1/2 oz tip weight , my own 1/8 inch landing gear 1/2 inch longer with gear doors. 64x.018 braided

lines with my Large handle 4" spacing. Blunted leading edge with original covering put back on with balsarite.

taped hinglines flaps and elevators.Omega 5% fuel with 1 oz of Aero 1 and 4 oz of klotz. 67OZ.

Flies very well , easy to fly great turns .In fact it flies as well as anything I have ever had. I am an

advanced flyer 450-475 scores. I believe the key is 14" prop. You can use these if you thin them out

on the blades and use 15% Nitro on St .60 (non -restrictive muffler ,lots of Castor) 14x6 or more pitch.

You will have to run them slower 7400-7800 with the big prop but try it you might like it. If you do not thin the

prop blades then it will be too much load on the St .60 . I bet it would work with the Merco 61 AND K&B

.61 also. Gid Adkisson with his Laser 200 used this set up with the ST .60 .the ;Laser weighhed 80 + oz

and had a 740 sq in wing . The Strega has a 740 sq in wing and will weigh less than 70 oz.

I am pleasantly surprised at how well this plane flies , not shocked as it has the big thick wing with lots

of square inches . BUT this means use a large prop..... If you try ot use a sick .60 with 12" prop it will be

not very good , 13" would be better 13.5 or 14" even better. I have cut down some Top Flite Power Point

14x6 props to 13.5 and thinned them I will try them if they work I believe they will be the ticked for the Merco,

K&B , St .60. I have a friend who claims the Merco will swing the 14" no problem. Also another friend

John Wright used thinned 14" props on his Merco 60 s. Best ARF yet. I will be using it for a test bed for

RO Jett .76, Saito .62 AND Stalker .81. Walter Hicks

Oh ya, looks like the nose ring needs to be cut off and attached to the cowl so you can get a 6 1/2 ounce tank in from the front.

It's a well-thought-out ARF - - Reasonable weight, good construction, excellent (Tom Morris) controls, fair covering (although better than I can do with Monokote. I am making only 3 changes:

1) The flaps are very "whippy" so I stripped the Monokote and re-skinned them with 1/32" plywood. Weight went way up but stiffness went up more.
2) Supplied hinges move roughly, so I substituted DuBro hinges
3) I added the Brodak (Windy) Engine Clamp Mounts so I could try different engines with a minimum of bother

First engine will be a YS .63FZ-S. I also plan to try the Saito .56 and .72, just to see. I asked Eric at RSM to make a couple of special tanks for this project, and I'll probably start with the 7 oz. version and hold the 5½ oz. tank in reserve. If the YS proves to be the "engine of choice" the smaller tank should be adequate.

bob branch · « **Reply #58 on:** January 20, 2007, 07:56:55 AM »

Please keep us appraised of the YS performance. In RC they are used for their very high power for size qualities but are usually running fairly fast.

You will want to round that leading edge more than the way it comes. Its pretty pointy and testing has shown it flies alot better with a blunt leading edge as the original had.

I responding after the personal email I sent you. I decided to follow Windy's advice and forgoe the shaft extention and lop the nose off instead. Basic reason was concern for prop security without a Jam nut. Anyway, since I was going to do a 3/4 inch shaft extension, I cut 3/4 inch of the nose instead. I marked in actually about .70 inches from the nose ring. The result was pretty good and just very nice in its result. It winds up being an absolutely perfect fit to a 2 1/4 inch spinner there. The top block still is intact and without a gap to fill in. AND... take a look at the resulting pic after cutting the cowling that I had already trimmed for the Saito at the same distance back... A scale mustang nose scoop! I think its a better way to go. This way standard spinners are not an issue, and you have the jam nut. Everything else remains the same. Balance wise it looks like its going to come in balpark. I'll ad some reinforcement to the cowl lip but I think this is probably a better answer than trying to deal with a 4 stroke with a shaft extension.

Too late on rounding the LE; that's why I got an ARF this time and plan to keep it that way. I turned the TF Score into an ARC with 40 hours of sanding and re-covering, and I'll never do that again.

As far as rounding the LE more, I wonder if applying thread "turbulaters" about ½" back from the LE might serve the same purpose as rounding?

Ralph...
Dong the leading edge is really quite quick and inexpensive....
Cut the film covering 1/2" above and below the center (sharp part)......round so that it is as blunt as you can make it.......touch some CA to the thin parts, and put a 1 1/4" wide piece of "trim" type monocoat (the kind that has a real sticky backing and doesn't require heat)....and go fl it...the process took my fired about 45 minutes, and that included a lot of self congratulations.....

Turbulators act more to delay a stall. I don't believe that is the issue with the rounder leading edge. Someone may want to correct me if I'm wrong.

I went flying with Jimmy Welch the other day and while he was flying his ARF Tutor the bell crank pulled out. The mounting system was OK but they had only glued one side. That got me thinking about my ARC Strega I went home and cut a hole in the bottom of the wing so I could get some glue on the bell crank mounts top and bottom, The bottom nut was a little lose glued that. and the lead out was catching on the rib in certain conditions , cut the rib down some to cure that problem. The wing and stab are ready to glue in, just have too block the tank compartment off from the wing area. Jimmy brought his new 830 sq. in. stunt plane with a LA 65 over to the house tonight and it immediately attacked my Strega.

830 Square inches? Welch built a sky Buick!!

Does it have a provision to attach a JATO bottle to it for help on takeoff and the reverse wingover???

<just kidding Jimmy! looks great, I imagine we'll see it flying long before my Avanti is done!>

Ralph...
Dong the leading edge is really quite quick and inexpensive....
Cut the film covering 1/2" above and below the center (sharp part)......round so that it is as blunt as you can make it.......touch some CA to the thin parts, and put a 1 1/4" wide piece of "trim" type monocoat (the kind that has a real sticky backing and doesn't require heat)....and go fl it...the process took my fired about 45 minutes, and that included a lot of self congratulations.....

OK, Rich, you were right. It took far longer to convince myself to round the LE than to actually do it - - About 5 minutes with a razor plane and 15 minutes with sandpaper; and it looks much better. Thanks for pushing me.

Any one using a 60 size engine in the Strega having a tail heavy problem? I have my ARC together now with no covering and a K&B 61up front with no muffler or tank it balances just about right.It's going to be close.

Joe Gilbert put in a few more flights on his ST-60 powered Strega last weekend but is still working on getting the trim just right.

I’m coming along slowly on my ARC Strega I have made a few changes like cutting 5 inches of the flaps and making the end of them adjustable on both tips. I made new 1/8 inch landing gear I thought the stock gear were to thick and would break their mounts in grass landings filed in the hole for the tank inside the fuselage filled in the hole in the bottom of the cowl marked in black in the picture. Moved the push rod hole in a quarter of an inch on the bell crank to cut down on the control a little. I filled in between the hinges on the elevator with Monokote. I have no idea what paint scheme I will use, all I know is the tail is going to be Orange and the wing is Blue

What CG location is working for you guys?

Thanks,
Jim

Joe Gilbert · « **Reply #77 on:** February 17, 2007, 05:20:23 AM »

I am at 6.75 inches from back of trailing edge of wing not counting the flap at fuselage. Seven inches is a good place to start.

Hi guys

Can someone explain how the 5/16" engine offset is measured?

Cheers

Jim Oliver · « **Reply #79 on:** April 24, 2007, 06:31:41 PM »

Hi Warren,

See reply 34 thru 39 for some details---as I understand it (I haven't done mine yet), with a 14 inch prop, the distance from the prop tip to the L.E. of the outboard wing is 5/16" less than the distance from the SAME prop tip to the inboard wing L.E., both measured with the prop horizontal.

Clear as mud, right???

Hi Wayne,

3M makes Scotch Brand Crystal Clear which is what I've been told is the stuff to use.

I went to an art supply store and found some 1" clear tape that is sorta pricey , but that works well....

Was adviced to increase rudder size when using 14" prop's and .76 engine.
