Hi

Just wanted to introduce myself & say hi. I'm a veteran pilot and own several foamies & balsa / fibre models but would like to start having a go at doing some scratch builds. I purchased a few sheets of depron foam weeks ago & have been looking for something to build since. David i think you have done an exceptional job here with your design & build blog & I'll be having a go at building one of these beautys very soon. Thanks for sharing

Welcome to RC Groups FlyingMonkey989 or shall we call you FM989? You can edit your profile to include your location (you may find a nearby foam basher), other interests and your 1st name if you wish.
I'm sure that Dave will be really chuffed that you've chosen his design as your 1st scratch build foamie and he would appreciate build pictures and any video when you fly her.
If you need any advice at all then just holler. If you have been lurking for a while you will have realized that RC Groups is THE place to go for all sorts of useful tip and tricks as well as plans for all manner of scratch built planes. Most full size planes have been modeled and some come straight form the twisted imagination of the designer. Too much cyano fumes?

Gravity rules...

ok its time to share....


Gravity is indeed a cruel master! the first attempt with the "wot-next" on floats didn't quite go to plan...

and yes i chose a rock hard frozen football field ("soccer" to our U.S. cousins)

and the one thing i didn't check was??????




centre of gravity


you gotta love the "landing"


anyway it is rebuilt with its 3 ounce depron floats with the c of g about a mile further forward

so... the next "test flight" is off water..

enthusiasm over ability rules!

Got scale templates drawn on large piece of paper for easy reference when drawing on foam, saves having to jump backwards and forwards on pictures.

Will start with fullsize and then make a smaller one for 10g motor.

That way i can use bothe the 1000 -1300 3 cells and 500 2 cells that have had nothing to fly in for a while.

HM,

I want to run a concept by you and see what you think. I want to alter your wot next idea but I am not sure how it will fly. I want to see if you might know how it will fly and what you think about the changes.

Tail group - going to keep it exactly the same, horizontal stab will be located at the top of the fuse.

Main wing: KFM 4 and mounting it center of the fuselage. I am removing the center former that is normally 1" from the top of the fuse and using the wing as the center former and locating it on the center line of the fuse. So the main wing will be 1.5" below the horizontal stab (unlike origonal design that is level with each other).

The tail group servos will be installed in the wing just like they were installed in the center former of the origonal design.

Motor will be mounted thrust line on the center line of the fuse in line with the wing.. This part I am not sure about, I dont know if the thrust line should be in line with the wing or slightly above.

Battery bay is moved from bottom to top with the fuse former located 1 inch from the bottom of fuse instead of 1 inch from the top. I mainly did this to keep the bulk of the ESC/Battery weight in line with the aileron control surfaces in hopes to give it a clean roll.

I sure hope I have not been too confusing. Really all I was trying to do was take it from a top mounted wing to a center mounted wing.

Any thoughts would be beneficial.. I have already built the wing and plan to start building the rest next week.

Sorry for the long winded post.

Wow! you just designed a new plane!

seriously though.. i fully understand where you are coming from and why you have decided to do it as you have described... it should work a treat!

i designed the wot-next to be as simple as possible to build so that folk who have never scratch built anything will feel like having a go.. and end up with a good looking model with a performance beyond its simple design! i feel that these objectives have been achieved..
however its simplicity does limit its performance and rolls are of the barrel variety due to the high wing position and the simple flat sheet wing has its limitations (you want to see it bend in high g but the wing and its position on the fuz do give it a certain amount of "high wing" stability for the flyer coming of RET trainers onto something with ailerons... that IS the point of the model.

you have redesigned it into a model that will have better performance at the cost of simplicity of build and stability... and yes you will have improved it...
go ahead... i look forward to seeing how it turns out..
please post it up on the thread for all to see with photos

thanks
David

Love this design. Just built an Ugly Stick from PMJASS design and now I am itching to get this one going. Love the Fokker scheme.

Hi David

My build of your model going well. I understand that the battery and ESC are housed in the front section do you have any tips or pictures of this?

Regards
Terry

welcome to the ever growing wot-next club...

everyone will do their own thing with the battery hatch...
mine relies on a single servo screw and a couple of strips of 1/32 ply for reinforcement. here is the set up on my now very well worn prototype (now on floats)






please post photos/videos of your finished model
