Thanks gents
Jeffo...CG on the drawing is UT, which is shaded.
UStik. Wow, thanks for the translations. I have built the undercambered wings very similar to the full scale. The model has a huge lifting stabilzer that is also undercambered.
The model is going to be powered by four AXI 4130/20 outrunner motors spinning 16x8 scimitar props.
I love your line "You should just look for a big hall to fly it since it won't cope with wind very well". That's very funny. I know that it can only be flown in very, very light winds. I had to build it, it is an amazing aircraft for its day. Right now I am adjusting the 82 turnbuckles in the tail. Yeesh..... Maybe I should start a thread in a more appropriate forum and show what I have done so far.
Cheers, Sal
