The build went well, but I'm not used to have such small space for radio installation !
The only small issue I encountered was the elevator control horn holes which were too large (1mm) for the 0.8mm piano wire. To fix it, I added a second thin plate of carbon (coming from the servo covers) and re-drilled at 0.8mm.
I ended with a empty flying weight of 227gr, with 8gr of balance lead for a CG at 65mm.
For the ballast, I found an aluminium profile of the right dimension, so could mold 2 ballasts: one at 85 grs, the big one at 190grs.
Maiden flight as soon as weather permits as we have bad weather and snow at the moment.
