Default WM 1/3rd P-56 Paulistinha

Hi All,
Am in the process of building the new WM 1/3rd Paulistinha. Most parts assemble together ok, others need a bit of work but nothing major. Have pics but rcu consistently times out so they don't post here. Was quicker to slap'em on a web page [link]http://hmarshall.net/p56/[/link]

All hinges, small metal pinned, are glued in place.
99% of all holes that need drilled are pre-drilled.
Two wing tubes with metal and self-tapping screws to hold in place, nothing on wing root bolts to the airframe.
To use the included control arms, need to order hubs, got mine from lynxmotion [link=http://www.lynxmotion.com/p-505-hitec-spline-metal-servo-horn-tapped.aspx]here[/link].
The rear geometry not that great, had to shim servos to get proper alignment.
2 small screws, 2 steel rods and flying wires hold the stab in place.
Tires have some kind of valve but no idea how they inflate.
Landing gear is preassembled, attached by a series of 6 plastic tabs, each tab straddles the gear frame and has 2 mounting screws. Hmmm.... not sure how well thats going to hold..
Instructions show what looks to be a zenoah 74 on engine mounting, but its upside down?
Cowl is pretty narrow, no more than 7 maybe 8 inches across.
Wing strut mounts are solid.
Door latch is cheap plastic tab, made a wooden mount on frame with insert to screw it shut.
Wing servo trays are done, also made of a hard plastic.
Overall construction looks pretty solid, tho do see some glue in spots.
Equip tray is supposed to be fixed. Added siderails and drilled them, so the tray can be removed if need to work on undercarriage.

Thats the highlights, not sure which engine am going to use, in running are G62, GT80, DA85. Let me know if have specific questions and will do best to answer.

Very nice. I have the smaller one from WM and its a nice flyer. I went electric and that was a bit of a challange with battery access. Also, there was no thrust angle built into the firewall and after first flight I added about 2 deg. right and down. I love the colors that make it different from all the rest. What is the wingspan?

Hello Harry,
Thanks for looking. The wingspan is 144 inches. Guess it puts me in the market for a trailer also!
Let me know if have other questions, will post more as I move forward with it. Enjoy the weekend...

Wow, thats 2x my wingspan. I would think yours is a one piece wing? Yes, transport will be interesting. I don't take my wing off and access through the windscreen for the battery. It just fits in the back of my pick up at an angle. A trailer would be great but then I would start spending some serious $ on biger and biger planes. Have a good weekend as well.

Harry,
Its a two piece wing. They recommend that the wing tubes be left in the left wing, (that one uses self-tapping screws), so you're left with one wing that about 7ft. long anyway! Bigger planes are a bit more problematic with handling, transport and such, but so much more fun to build and fly!

When we assembled my WM 1/3rd CUB we did not use their method of attaching the wings with the set screws through the top of the wings.

We used the two aluminum wing tubes and we tapped the root spars with a 1/4 20 threads and assemble the wings as normal and I reach in thru the CAB and use the nylon 1/4 20 bolts and tighten down. this marries the wing to the side of the plane.

This is used in 40% planes and works just as good.

100's of flights on and works great.

To see the plane in flight go to youtube and look for rorojax.

Roger, do you happen to have a photo of this. Think I understand but you know a pic is worth a thousand words. I have another plane I am thinking this will work well in.

Thanks Roger,
Think I understand also.. but if have a pic that would be a great help, I'm not real convinced their method will keep the wings on. Will also check out the video.

Here are some pics.
The plane is in Winter storage in my basement and kinda big to put together, But here are some pics thet I hope you can see how we did it.
We drilled and tapped the wing root first and then sacrficed a 1/4 20 bolt and put a point on it an then put wing on with tubes and pushed in to make a mark on the fuse to show us where to drill.
In the pics shows the fuse with the 1/4 20 in it, the the wing with the 1/4 20 and wing tubes, etc..........
Hope these help, nice clean install and no holes in the top of the wing and works great on the CUB and my 35% 260.

Well at this point still don't have the bird in the air. Basically the engine turned out to be the hard part. Settled on the DA85, as the plans call for at least an 80. Problem is, can't use stand-offs on the 85, so had to build a box which emcompasses the carb area, which also means everything has to be built 'in the box' prior to mounting. This also necessitated a different fuel tank, building a platform for the throttle servo and on and on. Finally seeing some light, so should have it ready to fire in a week or so.

Got it in the air saturday. Overall weight came out to 28.5 lbs. The DA85 provides more than enough power. Lifted off in about 10ft, required a few clicks of down elevator and a couple clicks on the rudder. Mid-throttle gives it a nice scale look in the air. Landings are pretty much a non-event, at 1/4 throttle it floats right on down, couple taps on the throttle to keep attitude and it settles in nicely. Only problem was the wind, could have been a bit calmer, was around 10 or so. In a light-no wind, it should be a lot of fun flat-turning and general low slow flying. Everything held up well, nothing shook apart. Limited flights to 5 minutes as using a 32 oz. tank. Came with a 55 but could see no way to use that and run the linkage for the DA85. At 5 minutes I'd have about 1/4 tank or slightly less left. Am looking forward to getting it back in the air and checking out the stall characteristics and so forth. If you've flown a 1/3 cub, heck even a 1/4 scale, this plane would feel no different. Was glad to finally get it off the ground!

Thanks guys! Here's a youtube video link to the [link=http://www.youtube.com/watch?v=fVWoCVnNc0M]Takeoff[/link]

And here's one of the [link=http://www.youtube.com/watch?v=qKx2cw1ttS8]Landing[/link]

Landing could have been a bit better, they will be once I get the perception part worked out.. bigger plane so have to tuck it in a bit closer. Its all fun!

Did you do the wings as I did on my CUB shown above.
If so how do you like that method?

Roger, admittingly I've not done that yet, wanted to see how things went 'out of the box'. After flying it, I think I'm going to do it or something similar. I don't trust the tubes at all, especially threading into a plastic liner. Am also considering putting in blind nuts and using machine screws, just for extra insurance. The wings are huge, so it won't take much of something to go wrong in that area to cascade to an unpleasant event. Will keep you posted..

Wow, I can't believe that 85 is such a gas hog. My G62 will fly a long, long time on 32 ounces!
