hi,

A friend of mine Col.H.K.Sil. built a coro wot and modified it for a 9cc NGH petrol engine. The model is built entirely from coro and 3mm ply for formers. have attached pics of the build.

more pics to show quality of the build. its a clean and true modellers dream

this is the beautiful masterpiece for which the model is built.

indeed.... very nice build...!  beauty.. and very clean..

Very neat build indeed.. what tool was used to cut the hole in this former.

beautiful build!! I'm thinking on the same lines as SunlikeStar.

if i have got it right, for the same cutting i use a FRET saw is used to ... a long u shaped saw...

u may have seen it with people who cut the wooden switch board (that is electric) i use a manual....

a finer blade will give u a smoother cut..... also u can adjust the tension in the blade for different cuts...

hi,

posting pics of the finished model.

engine is under breakin testing.

will fly soon.

 

  

please share details of AUW and CG. Visually it appears to be nose heavy I may be wrong though.

Bajare sir, Looks GRATE (Wingspan 64" ?),
Dimension please. And waiting for the flight video.

Thanks

Hai Bajare sir greet job, waiting for flying video     

  hard to believe that its a scratch built SPAD!!! Amazing craftsmanship 

hi,

Maiden flight today after all the waiting. The flight was right off the drawing board. no trims required and the CG was perfect.

wingspan - 67" tip to tip
All up wt - 3100gms
Engine - NGH 9cc petrol
propeller - 12x6

Initially the engine was erratic and not runnning well as the pump was too far after relocation, bringing it closer to the carb made quite a difference and the engine was running well and seemed to idle well with a 12x6.

pics below

congrats on maiden, this engine sniffs fuel, with a 220 cc tank it gave 45 min of Flg time

I liked it very much....! ;>)

post video

Awesome creation sir 

Video Pleeeeeeeeease!

Great Build there. An Absolute beauty. 

The pump with fuel line not located less than 85mm from the Carb is proving to be an tuning nightmare for most of us and which we realize late.  Here in Shillong cumulative with high altitude and low ambient temperature tuning temperament is multiplied many folds due to this.
