csdilley, you should have plenty of power. One question tho, with all the weight up front why go with a pull/pull rudder?

Ed M.

I have gone with pull pull on my U Can Do 46, and it is very precise, with no slop whatsoever. How is the stock setup?

How much does this plane weigh?

i have seen it at a couple of shows! It aint hard to miss stands out abit! Very strange looking plane!

Rob

Mine with a saito 1.00 is 8lbs and 3 or 4 oz.
I run 30% cool power heli w/APC 16 x4 w @9800 static
Adequate power but not a rocket

I brought mine home from the hobby shop today. I am really impressed with the quality of this building and the completeness of the assembly. The clear blue covering shows a great building job. I look forward to getting this one in the air!

I am about 5 hours into the assembly process, just completing last night the cowl and mounting the motor and beginning on the tail servos. once again i am impressed. i hope it flies as well as it is going together.

I need to know if the engine on the harrier can be side mounted instead of being mounted inverted.

Phil

yea it can be but it'll look bad

You will love the way it flies csdilley, it acts like a much larger plane and slows down so nice. I set my cg to the very back of the rec. and its still smooth as silk. I set the throws for everthing I could get and use a bunch of expo ( 60%). thing is a floater ,least mine is. not sure ya can stall it. I am having a blast with mine. If i did it again it would get a 120 instead of the 100 tho. The 100 is enuff, but just barely.

I am almost done with mine, just have setting up the controls left. I have a Saito 150 up front. Surprisingly, it balanced well, only requiring 3 oz of lead in the tail to balance mid range. I should test fly tomorrow. I will post and let everyone know how it is.

hmmm, let me know, I have a 180 sittin doing nothing, might have to give it a try. but then ......what to do with the 100

A 180? Please...that's WAY more power than this agile performer needs. A 120 is a bit more than the average pilot will use, with this plane. I don't see any need to add weight just to have more power than you need. Of course if you add the weight, you'll need the power...hmmmm. The Saito 100 is a perfect match. Just my opinion.

There are only 2 engines I'd consider for this plane: Saito 100 or YS 110. Saito 100 will have enough power for most 3D moves if I prop it right w/ 16x4W using 20%+ nitro fuel while keeping the CG tail heavy enough for easy harrier, hover and waterfall. YS 110 would be ideal if I want continuous snapping on vertical lines, using 16x6 or 17x4W.

I just flew mine -on a Saito 100 plus a 15x4 APC on Magnum #1 fuel.
Mine weighs exactly 7 lbs dry -
The servos are all up front and balance is spot on the recommended mark. I did quite a few equipment mods and the tail wires are simply two pieces -contineous.
Real thrust is 9 lbs
so -I have 9/7--or almost 1.3 -1 thrust.
Nothing to yell about and dead slow compared to my electric foam stuff.
But it is very nice to fly and I really like it.

Dunno how ya got it so lite!mine came in at right at 8 pounds. I tried a 15/4 and it was pretty anemic. Goes much better with a 16/4 W.
not sure of the meaning of magnum #1 fuel either but I just run 15% morgan fuel.

of all my planes this one has the worst thrust to wieght ratio. I've always way over powered em. when I bought the 100 I thoght it would kick A on my 91's, it barely out does em. Not really sure its as strong as one of my 91's it is very close tho. I had the 180 on a dp ultimate that was 9 1/2 pounds and it was perfect . figure Ill lose 1/2 a pound puttin on the harrier. I might have to do it. just need taller gear.

I'm putting one together right now for a friend. Going to use a OS 1.08 and side mount it. Side mounted engines run so much better then inverted engines do. It is one of the best ARF I've build. Each part was in it's owen box within the main box. It looks as if the parts were laser cut. The plane is small enough you can leave it all together if you have a van or wagon etc.

I swapped out landing gear - tore out the huge blind nuts -used none of the tail hardware and used only 5 servos -no spinner - etc..
I was SERIOUS about the weight as the Funtana was a real power to weight problem----------
Magnum fuels are a step up in power - from 15% -
I can easily document 12 ounces of dead weight left out - no problem
servos in the rer typically add over 3 ozs per servo - counting leads/linkage etc..

put up front - using ONE elev servo and a good fork pushrod is a huge savings and balances thigs much better.
Ever see a full scale plane with big ol servos poking out under the stab??

I wouldn't worry too much about the weight. I flew mine today for the first time. I have a Saito 150 and about 4 ounces of lead in the tail to balance. It flies wonderfully!!!! Since the wind was about 20 mph and gusty, I couldn't get too many hover/harrier maneuvers to look good. I can tell though that this is one sweet plane!!

I am building one now. Just took it out of the box and I am impressed.
I have a bunch of saito 180's sitting here, as I run all gas at the moment, but
I think it would be a lot of fun. The 180 also weighs less than it's 150 & 120
counterparts. This thing shoudl be a monster. I bought it to practice my
torque rolls and harriers on the deck. It's the only size glows I have besides
a Saito 65.

Where are people putting their CG for good all-around performance?

Hopefully I have this together in a couple nights... doesn't look like a lot to it.

Anyone using any mixing on your harriers? I use it on my edge 540 to stabilize the wing rocking...
anyone experiencing any rocking or bad habits?

Thanks!

My cg is at 175 mm behind the LE with the tank empty. it seems like a good location. i was flying in a lot of wind, so i couldn't give you an accurate idea of the mixes.

Stick the 180 in it- and it will pretty well balance out -
Note of caution: The plastic control horns are really a bit light weight and flex at their base.
I would recommend slipping on down to the spares bin and finding some sturdier types
Also the push rods are smaller than 2/56 types made by Sullivan or DuBro etc.
I fly mine, VERY slowly so there is no real problem but if you ever develop some speed -the existing horns may flex too much .
As for the "harrier rocking -- ANY tapered wing layout will rock - -It is simply restabilizing at work
The short low aspect ratio wing is best ( my opinion) to provide a steady vertical sink.
Why?
Simply the span flow is very high on these setups
If you ever flew "Flying Stop Signs " or big flying plates --you see the same thing - the air runs outbound from center and stabilizes, at higher angles of attack .
Nothing mysterious - air , like water -simply looks for the easiest way around an obstacle
Just like a V prowed boat.
Any way - it works
It is a nice model -just needs a few minor hardware mods.
Note to Moderator: apparantly the picture upload is not working - tried 3 times with large/small pics..

FAST BUILD?

This is the easiest arf so far. Had a few packages of GP control horns, a bit more sturdy.
On my way home from work last night grabbed some 4-40 misc rods I can cut to length.
Also upgrading the H9 clevices.

It took a matter of minutes to glue all of the surfaces. This is usually a time consuming
process on my larger gas models drilling, tapping, and installing the robart hinges etc.

I went back over the hinges a few minutes later with a little more thin CA, then wiped them down
with a little paper towel coated with debonder. This AM when I checked them they seemed very firm.

I've just finished cuting a true turn 2 1/2 (per instructions in this thread or another) and using an
APC 16x8 prop... not sure if there enough room for a 17x8... I will try it later.

It also took a matter of minutes to install servos in the wings. Very easy when you can see what you are doing.

Having the wing tubes is going to save a lot of time as well. I suppose this all makes up for all the time that is
supposedly spent on the flying wires?

Now, got to dig up that Saito...........

Well, good news; I finally sat down to do some work to the model. Noticed when I glued the ailerons
they are slightly inset so the tip of the wing and the aileron don't line up. Did the same on both sides... must have been
looking at the trailing edge of the aileron. Oh well, minor! lol

In one evening, All servos are installed w/ extensions, new pushrods cut and installed on ailerons w/ new hinges.
Fuel tank and tubing installed, and I futzed around with the stock engine mount for a bit before I got the Saito
1.80 to fit. I manages to make a small inset on the firewall for the edge of the saito's carb to sit in, giving me
a couple extra mm to work with. Throttle linkage was easy to relocate, and worked out nicely. The saito barely fits,
as it is a little wider then the smaller engines. Lots of trimming on the bottom of the cowl, but it came out nicely w/ a small
hole to the left for needle valve access. This thing looks like a monster w/ the hemi sticking out the bottom. I love it [8D]

The only thing I am wary of is the carb feed is below the tank. I ran the exhaust to the tank instead of using the crank option.

I bolted up the landing gear brackets just to take a look at clearance issues, if any, and made some adjustments to the
saito's muffler.

There is not a heck of a lot more to do! Just attach stabilizers, and make new pushrods for them. Do the landning gear + wheelpants
and make some final adjustments to the cowl. Finishing touches will be my tru turn spinner, and decals..... then test the CG with RX/battery placement.\
This is a fast ARF so far. My club picnic is this Sunday.. and this one WILL be flying. I'll spend most of Friday and Saturday breaking in the engine however.
We'll see how far I get in the next night or 2.

Has anyone tried a waterfall with this bird. Mine wants to go to the left when going back upright. Has anyone else had the same experience?

May need a little more right thrust.

Jim
