Heya all. Finally got a day to play with my new UCD setup, .91FX 15x4W APC. Had lots of fun, thot I'd share it with you. It's a 40MB .WMV, so be prepared lol, but it's 4min runtime. Enjoy![8D]

Awsome-Great video work.Just getting ready to put mine together was going to use a ys63 but am having second thoughts.Looks like the 90 size motors are the way to go.Did you have to make any mods to get this set-up to work well cause yours does.

Only thing I had to do was add 2 oz. to the tail to balance it out at 6". Fixing to head out again today, gonna try to burn another 2 gallons lol.

Would like to see some pics also-Side shots of how 91 mounted.Did you use stock mounts.Did you leave fuel tank in stock position-Your 91 runs great did you have to run a pump because of position of tank to carb.Thanks in advance of the answers.

Looking good out there. I want to see some photos also. What do you think about putting the saito 91 4c? are you using standard servos. Let me know your set up, as far as hardware, servos, etc... I might be a future owner. Thanks a bunch.

What about the UCD3D and the Saito FA-91S combo ??? Did anyone already tried ??
Let me know the results guys...

I placed one on mine using the mount that came with the plane. You have to mount it at the very end though. I placed my battery pack and reciever right behind the throttle servo. No extra weight was added. I use 3004 servos all around except for the rudder. I used a hitec 605bb here. I did pull out the firewall though on a very ruff landing. I ended up replacing the firewall and mounting the Saito right side up. I did't like the fact that the carb was below fuel line and the fuel drained into my motor. It may look ugly, but it flies and FLIES GOOD! I seen the video with the 91fx on it. Looked good. I gota say, with a apc 15x4w prop on the saito, I can take off in 5 to 10 feet and pull back and go straight up with no end!

That's the combo I have, though I haven't had the chance to fly it yet. The Saito .91 fits great in the cowl, but as Capt_Kc said, you have to put it right at the end of the mount. I also had to replace the upper left motor mount bolt with a countersink head screw to keep the carb from hitting the bolt. Mine balances at about 5" back with the battery under the tank and the rudder servo mounted just behind the cockpit and using pull pull. Weighs about 5lbs, 12oz. Should be a blast.....

did you mount the saito 91 upside down in the cowl? What servos did you use? Im about ready to buy one with the same combo. When will you maiden? Im looking foward to hear the flight reports. Let me know.

THanks,

Here are the pics of the setup, Hitech 525MG on throttle, and both elevators. Hitech 645MG on rudder, Hitech 625MG's on ailerons. 6v reciever pack, stock fuel tank and tank location. 2 Oz. lead added to tail to balance.

Left side.

Right side.

Engine/silencer/mount, stock mount, just had to shape it with the dremel on the inside of the rails to fit the engine.

Servos used in the ailerons.

The plane.

This is the pilot for those interested.

This is the lazy sob on the tail.

Santi,

I mounted the engine as per instructions. No problem getting it to fit in the cowl. You don't even have to cut clearance holes in the bottom for the valve covers, but I probably will for cooling. The only problem is that the rear of the engine hits the motor mount screw on the upper left corner, so I had to use a countersink head screw for that side. Other than that, all works well. For servos, I went with what I had on hand: Futaba 3004s on the elevators, Hobbico CS-65s (Hitec 605 clones) on the ailerons, a Hitec 645MG on rudder, and a Futaba 148 on throttle.

Looks like I won't get to try it out for a couple of weeks as I only get to fly on Saturdays, and this weekend we have to go out of town. Can't take the planes with me, unfortunately.

I couldent resist the temptation. I went to the LHS and purchased one with the Saito 91. I went a head and bought the 4-3004's, 1-CS-65 for the rudder and a CS-12 micro servo for the throttle. I am hoping that the 3004's for the elevators and ailerons will be enough for this little bugar. As far as the hardware. I assume you are using what was supplied. What do you think should i go with something more torky on the ailerons? One more question Did you run 3 lines or 2 lines on your tank? Any comments would help.

Thanks,
Santi

I went with 4-40 pushrods on all the surfaces. The elevator servos seemed to be too far from the surfaces to use the 2-56 ones supplied. I was afraid they's flex too much. I also went with pull pull on the rudder, just to get some weight out of the tail. When I put everything in the plane, I realized I'd be tail-heavy with all servos back in the tail, so moving the 2oz rudder servo up helped. It was just a personal preference, but I also used the post type control horns because they provide a lot more adjustment that the regular horns. Oh, and I used the Radio South CA hinges. I've used them for years and never had a problem. They're stiffer than the supplies ones, but they hold.

For first flights, the battery is under the tank. I may move it back later if needed. Right now, the plan is for a two line tank system, and as soon as I find that Dubro fuel valve I have laying around somewhere, it's going in there, too. I'll try to post some pics tonight of my installation, if you want.

Hi,
I have just bought UCD 46.
can some one advise me on how to mount the engine right side up?
Do i nead to change the original mounting holes?
Do i nead to be aware of somthing?
Thanks...

I've been contemplating putting a YS 110 on the nose of my 46, but I just can't help to think it will load up the wing and make the plane a dog. One thing is for sure, it would definitely make a YOYO out of it. How did the one with the Saito 100 fly?

odrizin

when u change the engine mounting did u change mounting nut screws or did u leave them i the same place?
what modification do i nead to do inorder to mount the engine right up side.
Thanks.

Bobby,

Why don't you go for the .60 sized UcanDo3D ?

BobbyRichardson

Strykass

That probably what I need to do. I was expecting better performance with the Saito 72. It's hard to get 2 to 1 thrust to weight with a plane this size.

Capt_Kc

odrizin,

Well, the modification wasn't by choice. When I came down at a nasty angle on a dead stick, the motor ripped the firewall out. I ended up replacing the firewall and had a clean slate to start with. If you want to redo yours, just take a dowl rod and some 30 min epoxy and knock out the blind nuts, fill the holes in and remount the motor. I lowered mine just a tad. I used to have a os 50sx on it and it vapor locked twice on me. I was scared the saito would do the same thing and I would damage the push rods so thats the reason I mounted it up right.
