Excellent frame, I use this as its very cold where I live and the stock plastic frame get brittle in the cold, the l-ma frame is very durable and this is the first thing I have broken in 3 years of crashing the m1, my only criticism is the stiffness of the boom support, it resonates at 11Hz which is well within the frequency of movement of the helicopter and as a result this resonance make tuning the flight controller somewhat more difficult, this being said I am using a non standard flight controller, if you are using the stock FC then all you have to do is lower the gains on the pitch axis, overall I am very happy with the product and the service I have received from L-MA, nice work guys !
