Had to Post my thought on the Brodak ARF Oriental.
Did some Mods to it but it flys great.
1. Change the pushrod to carbon fiber typu and new klevis.
2.change hindges to pin type.
3add 1 1/2 oz of tail weight
4. move landing gear back 1" to line up with leading edge of wing to help better landings
5. Bushed control horns
6.3/4 oz of out board wing weight.

powered by a Magnum XL36 with 3 blade 11 2.5 x4.4 with lap times of
5-5.3 Flys GREAT.

Did you install the landing gear with the stock wood screws? The gear installation looks like it's going to be a weak spot. Did the nuts provided for the axle screws match their threads? SAE vs Metric.
I fuel proofed the engine bay with a few coats of clear, as it appeared to be exposed. (the wood) Did the fuel tank bay the same. I was extremely pleased with the quality and detail and the wing darn sure "snapped" into place. If I were to judge between the Nobler and the Oriental ARF on the basis of quanity and quality...Well???? The Oriental was worth the investment...Say what they may about "ARFs," but I believe they will help in; the already resurgence of C/L stunt. Anyway, you got something to fly and practice with while you get that "Easter Basket" ready for the NATs or a slot on the USA Team.

No I used a 1/8" ply platform for the gears and 4-40 with blind nuts,
yes I had the same problem with axles so I use 4-40 allen with locking nuts...hope you see the pic that Heman posted for me .

What length lines?
Tank?

FWIW, I purchased Windy's Cardinal ARF video. Pretty much builds it straight out of the box using the CA hinges, stock pushods/keepers and CA adhesive for the fuse/wing joint.

He uses an RO-Mag-Jett 36 (a modified Magnum 36 XLS), RO-JETT fuel filter, Scott Dinger tube expansion muffler, RO-Jett plug, a Brian Eather 10x5 3 blade CF prop and an aluminum needle nose spinner from the Ukraine. Brodak tank with all tubes forward. Kinda high-zoot power train setup. Wished he would have tried the LA-46 (like I have for mine).

The video barely shows any flying footage or trimming - he says that is available on another tape. Only comment was he thought it was slightly nose heavy.

I posted a product review (in product review) topic #214 on the Oriental ARF a couple of weeks ago. Did much of the same things you did...with a little help from some friends;)

It was Yellow day at the GSCB field today.....two Oriental ARF's appeared! Both flew well and appeared fairly straight.
Mike Cooper used an OS .46 LA!!!! nose heavy, because he wanted the cowl to look cool.

Mike resorted to enough soldier to complete a house as tail weight, but got it flying pretty well!

Gee, it's a shame that Dee Rice didn't design that plane for a smaller, lighter, readily available engine. Then all that extra tail (dead) weight wouldn't be necessary.


Oh!! Excuse me for the error. He did, didn't he? How would a stock Fox .35 work for that airframe? Maybe even, if light enough, a Max FP or LA .25 run in its most efficient state?

Hi, OS.
The maiden flight of the Oriental ARF was indeed with a STOCK Fox .35. Even with a tongue muffler, wooden prop and plastic spinner, I had to add almost an ounce of tailweight. I guess the tailfeathers just come out light.
When I switched to the Brodak .40, I added a tad more tailweight and it was perfect. The .40 hauled it with considerably more authority than the Fox.

Hi Guys, I am thinking of using an OS FP40 as power for my ARF Oriental. How do you think it will work? Thanks, Dave Markley

Windsurfer,
The OS FP .40 would be a great choice. You might have to tune it down a bit though. I have a T-Bird that was solidly 'slammed' the corners around and through the pattern with that engine and was a thrill to fly. In fact I am using a 11x4.5 prop with GMA 10/22 fuel, on 58 ft lines and it has been a great set up. I have used it for the T-Bird, ARF Nobler and will use it for my ARF Cardinal. I decided to try the Brodak .40 with my ARF Oriental so we will see how that goes. Good luck!

Olive you keep
on flyn'

Is this the round or square finned Magnum? Early square finned ones were called XL, then changed to XLS. How much fuel do you burn? Muffler type? Venturi size? My OrientARC will have the square .36. Sounds like you've got a nice model. Steve

It seems I remember an article awhile back in which someone had a conversation with Dee Rice. He had quite a few things to say about the original Oriental. It seems it had wing moved to balance for different engines. I beleive the comments were in the article for the Oriental II that was published as the most up to date Oriental. It is bigger than the original. Also guys, remember, when this was designed we did not use mufflers. That muffler would require a lot of tail weight I beleive. So has anyone tried the Oriental with a box stock Fox 35 with no muffler? My Nobler has shaft extension to get it to balance, actually the Fox was shorter than the OS that used to be in it. Later, DOC:)

"Box stock Fox 35 with no muffler"

Why would you want to do that?

Bigiron13 · Nov 09, 2004 10:15 AM

#21 source
Isn't that the way it was originally designed??? Perhaps to check how the original came out balance wise!!!

Guys

When I returned to this sport, I decided that I would learn all about getting Schneurle motors to work and forget about baffle-port motors from yesteryear--especially Fox 35s!

However, thanks to one of our very good friends on this forum, I have a NIB Fox 35--if that is the right term for a motor run at the factory before dispatch--awaiting a home. Our friend believes that I had a deprived childhood as I had never owned a Fox 35--so he gave me one.

After a partially blocked transfer port, a stuffer backplate and a Randy Smith balanced crank are completed, my Brodak ARF Oriental will be home to my Fox 35.

As for the model itself, I am still thinking about the braided cable leadouts running direct in the holes in the bellcrank and I do not like the elevator pushrod.

Otherwise, I have a model where everything in the box weighs 29 oz. The motor, muffler and tank are a bit under 10 oz so, how much glue and balance weight will I need? No matter, 40 or 41 oz is a realistic target with a nice light motor that will not shake the nose apart.

In fact, I will probably break the nose off and do other damage before the moter causes any grief.

Cheers

Geoff

An update on Mike Cooper's Oriental.....he removed the LA and installed a Fox .35 with an extention shaft and no muffler....that corrected the balance problem and it seemed to be okay powerwise.
I believe that Mike (or the instructions?) might have hooked the elevator pushrod into a hole too far from the hingeline, resulting in less elevator movement that flap movement....he is rectifying that situation this week.
The Oriental is kinda short coupled and I would imagine that less flap movement than elevator would work fine.
