RC Concorde EDF Scratch Build

All,

I am currently scratch building an EDF Concorde (see www.rcconcorde.com) and I cannot find any sufficient info on the center of gravity position on the aircarft.

I am fully aware of the transfer/moving of fuel they had to do in the real thing, however I still need to pin point an accurate position.

The only info I have is this link:

http://www.concorde-jet.com/e_transfert_carburant.htm

Unfortunately the above link does not give any measurement to go on, If i have this then I can work it out from the scale I am using for this build.

Anyone who has built their own model before, i would be keen to know what their experience was with this and how the test flights were effected?

Thanks in advance

Thats a good question, sorry I can't help you but I suggest cut out smaller cardboard shape of Concorde in the scale manner and keep on ading nose ballast till it glides nose down. In my earlier days I built dozens of them using foamcore either prop pushers or later 64mm EDF powered. I used to call them "Kockcords" All brilliant fliers just make sure they are nose not tail heavy, Joe.

Sorry, you miss understood my above reply. I put in in wrong words, my grammar! not trying to be a smart ass. I ment, "All brilliant flyers" those "kockcord" models I have build, but despite all this "rib rib, wink" which I haven't got a clue what means I do consider myself to be a brilliant flyer and I challenge you anytime any place with anything that fly, Joe.
