Greetings Dave Wilshere . Appreciate all the info you are posting here as usual. Planning to get a diablo but I am concerned that you mentioned the fuselage is very light and that care must be taken. Just how light are we talking as compared to a J10 or Rebel Max? (I have the Max myself and it is built very minimally as well, with a 210 I can still yank it around the sky pretty good). I wonder if its even thinner than the max... I worry that this jet may be a bit too fragile and must be flown very carefully (that concern might be unfounded). What would you say a straight line "safe" top speed is on average with a 210? The 2M rebels i believe have similar construction but is a little smaller and can be flown quite fast and more agressively. I enjoy precision/pattern flying, Im not really into 3D but I think it might be something new and fun. I do like to get a little agressive as well and fly inside a tighter box. Always loved the looks of the Mephisto/Diablo, and 3D might be something new and fun, but just unsure if this airframe is suitable for my flying style.
