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.

This guy looks like he knows exactly where it is, why not email him I'm sure he'll be only too pleased to tell you
