Some answers to your questions:
No dates on mylar version yet, i still testing it, so far it looks good, but i want to be sure it is strong enought for regular customers.
Spies wingspan; 80cm
Fuselage lenght; 90cm
I used carbon tubes all around. Also i made shorter servo wirres, i do this on all my models, if you do not pay attention to small details you end up with 10g heavier plane...
