here is the new Dave Brown .25 mount on the mini 3D- This is a much better set up than the stock mount- I will say that they state clearly in the manual that the stock mount is for a .15 only- I had to push it......... I also put some cross members across the bulk head and put a blind nut into the back of them- then I attached the firewall with 2 4-40 SHCS- and then used the recomended servo screws for back up- all in all I am pleased with the outcome-
