Oriental Power

Ok...I'm getting ready to "power" my Oriental ARF....I have four choices (all of which might be wrong) so I thought I'd ask "Which one?"

I'm considering the following engines:

1)...An ASP.36 ..runs great!

2)...An Enya 35..also runs well

3)...A Fox.35 (probably with a burp problem)

4)...Brodak.40...still in the box

The brodak seems to be lightest of all by as much as prox 1.5 oz. but if I have to add nose weight the "lightest" weight becomes moot..

What say ye??

I'd go for door number four. Install APC 10-5, follow instructions.

If it's an early motor and gives ya fits, send it back for a replacement.

The last two B40s I have seen were quite good, although one (Will Reeb's) didn't show us much until he went to above prop, having been using APC 10-6.

A Fox 35 won't "burp" when run inverted or upright. Condition is tied to side mounting on profiles. Do not ask why...

Dan is much more experienced with the Oriental than I am, but I believe that he has not yet tried the unmentionable engine(s) on his Oriental yet. At last report, he was using a Fox .35. Were I in your situation, I'd use the Fox on that (presumably, based on the planes I've seen and about whose weights I've been informed.) ARF Oriental and save that Brodak .40 for a project requiring a bit more oomph than that which the Fox .35 develops, or possibly even use it on a profile. It has been my experience that the Fox doesn't burp at all mounted upright or inverted, and very little side mounted unless I run it so rich that there is no break into the two cycle. If you need power and nose weight on a future plane, that Enya will do fairly well side mounted if it's broken in.

My 2¢.

The Brodak has plenty of power, and is a nice running 4-2-4 engine. You can't go wrong using it.

>>...but I believe that he has not yet tried the unmentionable engine(s) on his Oriental yet.<<

And won't. It will need to be a new Oriental since Dan sort of trashed the old one. Sigh... Nice flying plane, that.

All that being said, I suspect a very light Oriental, as the ARF planes are reported to be, might get away with an OSFP20. I think it may be straining things a bit, but worth a try.

Oh, and Dan Oriental used one of those whiz-bang, Don McClave blessed Fox 35 engines. Not your momma's Fox 35, that's certain. Ran nice too.

Considering the information given, and the typical breezes in your area, Door #4 would be a good choice. In addition to the 10-5 APC, try a 10.5 x 4.5 APC.

IF Door #1 has the square-ish cylinder head, that would also work well, being the Magnum XLS .36 under a different label, but coming out the same door. If the ASP has the round cylinder head, it's pretty heavy for an Ornamental, but should work on a Cardinal.

My 2005 model Oriental has an O.S. 35FP. My 2004 model has a Brodak 40. Both planes weigh 42.2 ounces and fly very well.

The Fox will not "burp" on this plane.

I guess your power choice might depend on how heavy the plane weighs. Any of the engines you mention will power it just fine if the weight is matched to the motor. Sorry for the cop-out.

Enjoy,

Thanks for all the input.....Anybody know if the Oriental ARF is requiring any nose or tail weight to balance?

My Oriental has a fp-40 with a tounge muffler. It required 1 and 3/4 oz of tail weight.

My 2005 model started at 41 ounces with the FP 35, but I had to change to a metal spinner for some nose weight. It's now up to 42.2 ounces, exactly the same as my 2004 model.

The Brodak 40 in the 2004 model is almost too much power. It just loafs through the pattern in a strong four cycle. It breaks a couple of times, but really runs great. I'm using a 10.5x5 BY&O, 62 foot lines, and I like a 5.0 lap time.

'dis be de one. Ain't goin to be no nose weight needed, no tail weight neither. You gotta break it in like the man say, use 10/22 half and half, use dat APC 10-5, 10.5X 4.5 like the other man say.

Jim,
What tank did you use? Pressure or vent? What muffler on the B-40?

Steve:
I used the Brodak 3.5 oz medium wedge, all tubes forward, uniflow, Brodak factory muffler.
This seems to be a good combo and CG seems right to me. I am going to acquire a tonge muffler to see what it will do with a little less nose weight. The 4.0 wide wedge I had on hand was a little too wide for the Oriental tank compartment(actually, the end caps took it over the 2.0" max width. I hear this has been corrected on later tanks). The 3.5 oz is enough, actually about perfect, unless it goes off a little too wet. Prop is 10.5 X 4.5 APC, lines 65 ft center to center, 5.0 to 5.2 laps.
A flying buddy just went to an 11-4 Zinger Professional(looks nice-thinner than a standard Zinger)and is pleased with it getting laps down to 5.2 to 5.4 with 65 ft and a feeling of even more thrust and power overhead(he says).

I have a Brodak 40 in a kit built Oriental I had to put an aluminum spinner on it which balanced it just right. Dave Browns 2 1/4 inch. Great runner!

What's a good finished weight for an Oriental?

I know people that have built several orientals and had good success with them.
They tell me that they all build nose heavy (very)and require at least 1oz of nose weight OS40fp power
A friend of mine put a Aero 36 in a Brodak ARF and it was really nose
heavy;almost would not do any kind of pattern.
These people are very compitent and CREDITABLE flyers
I strongly advise taking this advice when pre planning building of your plane
Remember , this plane was designed for a Fox 35 which is a lite
engine and had no muffler

Whoops make that yail weight.Sorry

I meant tail weight(hmmm. I must have gotten hold of some bad shine )

Don't make me hitch up the mule again, boy.
LMK if you really want the premium stuff. Still remember the roads through the mountains into Tenn.....
