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.

Title: Re: Coro wot build for 9cc petrol engine Post by: AEROVISHWA on July 29, 2012, 11:38:03 PM 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... http://en.wikipedia.org/wiki/Fretsaw Title: Re: Coro wot build for 9cc petrol engine Post by: prashant_rc on July 30, 2012, 05:31:40 PM Wings look so good (aerofoil), nice work, can u post build pics of wings

Title: Re: Coro wot build for 9cc petrol engine Post by: sbajare on August 30, 2012, 07:55:35 PM 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 Title: Re: Coro wot build for 9cc petrol engine Post by: rcpilotacro on August 30, 2012, 08:21:42 PM congrats on maiden, this engine sniffs fuel, with a 220 cc tank it gave 45 min of Flg time

Title: Re: Coro wot build for 9cc petrol engine Post by: sundaram on August 31, 2012, 09:42:55 AM 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. |
