how sure are you, that it says top wing.

I just googled a chinese character translation site and that's what came up. I'm pretty confident that the translation is correct

Stan. I put a 4 oz heavy hub on the prop shaft and another 2 oz of led screwed to one of the engine mount rails. The engine is a saito 91, so if your engine is smaller (lighter) you will have to add more. Mabe other piolets will like it more tailheavy. Mine setup like it is lands very easy, which is what I want with this plane. The ballance point has got to be from the top wing.

Thanks for the info. If I may ask, where did you put your battery?, and do you balance the plane inverted or upright? Thanks again, Stan

Status: offline 		OK thanks for that, Yes you balance it upright, 58mm back from the LE, I'm just about done with mine, I moved all the servos up front also, Their's slot holes on each side of the throttle servo spot when you look in, and i used those holes to mount the servo's with a 1/8" plywood strip on top so the sevo can be screwed down on, And also after i was done with the stab/wing aliginment, I used a thin coat of epoxy and glued the tail, I used the screws to hold it down tight while the glue dried, I just didn't want to trust those screws, Super tiger 75 for power with a Jtec pitts muffler.

Status: online 		Stan. Sorry for the slow reply. I put a 2000 mah 6v pack under the tank platform against tje firewall or, subfirewall. I flew it again today with the 3/32 shim under the front of the horrizontal atab. Was able to take out more of the down trim, but not as much as I had hoped. Has anyone else flown this plane yet?

Status: offline 		I just started puting the top wing, And your right about the struts, The two front one's are too long, I had to drill new holes in the struts to get the wing level, If i used them the way they are, You can see the positive angle on the wing WAY TOO MUCH, And it still not right when you stand behind the plane the left wing is about 1/2"-3/4" back totaly out of square, Seem's like alot of BS i'm about to find about this wing installation, How was your's. jc

Status: online 		John the wings on mine are out of square also but I chose to ignore that and concentrate on getting the incidences correct. I think I will make new front struts-shorter. Would have been easier to make the rear strut mounts(wood incerts) longer befor I glued them in. The horrizontal stab is not in line with the wings either (paralell). As the stab is screwed on this will be an easy fix so I will do that later. I still think this is a good value for the buck kit. I just need to pay more attention to allignments befor I glue.........................................antiquefer.

Status: offline 		Thanks, I'm slowly getting it, Also the the very bottom of the outer wing struts(top wing) are stopping it from bringing the left wing forward, So i had to trim, They were'nt cut to match the profile of the wing, That gave me some wiggle room, I'll have it in the air next wee kend for sure. jc

Status: offline 		I finally have it done, It took most of the night, Now that it's done the balance is still a little tail heavy, I have the brass HiggleyHub, With the Brass lock nut, Battery on the tank behind the firewall, Could use at least 8oz more, But all in all seem's like it will fly good

Status: online 		The generous wing area wil allow for extra weight of ballancing. I screwed a flat piece of led( about 6 oz) to one of the engine mount rails, along with the 4oz heavy hub. Do you have an incadence meeter? I would like to know what you have the top wing set at compared to the two others and the horrizontal stab....................................antiquefer.

Status: offline 		I squared the stab with the bottom wing, That's perfect, And I don't have an incedence meter, Had the Robart one, But the Needle in the meter started sticking, It's all by eye, I taped 2 piece's of music wire on the lower and mid wing leading edge in line with the outer strut's, And used them as guide's to line the top wing, So all the leading edge's line up, Then i uesd a Bubble indicator to level the plane on the stand, Once the plane is level, I have a Craftsman diel type incline meter that's pretty accurate and set that on the top wing and got -1 degree down pitch, I even use my GPdr for a little refferance,I'll take some pic's and post em', By the way I don't even know your first name . Thank's johnc

Status: online 		Your wings look about right. I will shoot for 0 or -1 degreese. I had one of the robart guages also and it did the same thing. Now I have a digital by H9. Very easy to use. Tell me how it flys..........My name is Boots, but i just use my email address name..............................antiquefer.

Status: offline 		I received this plane as a gift from my students. I started putting it together and noted that if the inner plane strut supports are attached to the top and bottom wings, that the inner plane struts won't attach to the middle wing strut support. The midwing support slot is off by about 3/4 of an inch. I am wondering if the builder cut the slot in the wrong place. There seems to be a box in the wing at those support spots. When we line everything up with the wings, the struts line up perfect with each other and sit correctly on the wing. I was wondering if moving the slot back will be a good decision. Seems like others changed the struts and had wing incidence problems. I just wonder if that is why the wing incidence was off???? Any suggestions?
