@ David , I used the wing profile selig 7055 as ivan and the airfoil outside of the outer nacelles has a leading edge cuff. the angle between the wing and the stab is approx 4degrees .
The motors are inline with the wing. i hope i can get that nose down sit like the real thing had.

Wich airfoil did you use ? the Göttingen like the real sunderland ?

yes i went for the scale section, its looks right with its big blunt leading edge.
i also went for scale incidence angles being +7deg main plane, +4deg tail plane and +4deg motor thrustline, i want to get the "sit" in the air right.

as Sopwith Mike pointed out on yours, i have also gone for the more scale like deep "V" on the hull. based on the loose idea that the model is very light and wont sit as deep in the water as the real aircraft..... i hope!
only time will tell if these were the right decisions

keep up the excellent work

1/2 scale
Hi Bart.
I have had the pleasure of seeing Ted Russel's "Empire" fly many times.
I also have the pleasure of obtaining Ted's 1/10 version of the Plane. (136")
It is probably 70-75% built, he ony sold it to me as he is moving soon and did not want to pack this with him.
It was set up for 4x 1.20 FS, but I only fly gas, so possibly 4 dle 20's or the like.
Also toying with the idea of electrics, but I have VERY little knowledge of the "black art".
The first item to address is getting the flaps to work in a scale manner, something Ted has played with for some time.
Hopefully, I will have some progress done in the new year, really looking forward to flying this. especially as a tribute or salute to Ted, as he has done so much for float flying in British Columbia.

Cheers,
Dave.

Great !! did you read my first post ?? i have seen tTed's model on the cover of MAN in 1994 !! ever since then i wanted to build an empire. Do you know if there's is any video if ted's model? Hope you post a build thread of your great project. I think electrc is a must i combination with a good sound system. Flaps ? that will be hard the original had Gouge plaps and NOT fowler flaps, making them scale will be hard but not impossible. There is a great dutch modeller who has build a 1/10 sunderland an he has used fowler flaps , looks good though.

Cheers,

Bart

Hi Bart,

please make the bottom/side-junction as sharp and precise as you can. The planing performance will depend on how well (or not) the water can seperate at these edges!
Also the step: a sharp edge is needed for good flow-seperation. If the model "sticks" later, the reason is often a soft, round-sanded chine...

Regards,
Kuni

@ Kuni , Thanks for the tips's

@ Joe , Today i found out that moisturizing the balsa using a small sponge and warm water with dishwashing soap gave me good results. The soap foam from the sponge penetrates the balsa grain easy and makes it softer.
I also hear great things about the amonia drain but im affraid the chemicals weaken the balsa perminent.

bought hobbico balsa filler today , gonna need it

Bart

I have used amoina with water mixture for a long time and had no bad effects .When i get lazy i even use windex with amoina straight from the bottle . Each builder has his own methods or works best for him and i like watching all of them . I have used your sponge method after i sprits it with the spray bottle ,if i get carried away i get my weekly bath too. joe

You lucky bastard !! i only get to bath the second day of cristmas
Take a shower on the even days though , do not make a lot of clothes dirty too
( one bad habbit i picked up in the royal dutch army ) LOL

Here are some pics of todays progress , plan to make the sheeting smooth tommorow. There is a light bump in the aft sheeting , the stringer underneath is a bit too fat out , have to find a way to make it smooth. Maybe i'll glue an additional former insde the dent.

Made a start on the nose sheeting. Next is applying the side sheeting ( bottom half only ) , filling the seams and sand the sheeting smooth.
For this complex round form i found it impossible to do it in 1 piece so i used several strips of balsa

Cheers,

Bart
