Blending,
I just started building mine tonight and have not drilled/installed my motor mount yet, but mine appears to be solid!
Did yours balance with the OS 91 fx on the nose and 3 standard size servos in the tail?
I was hoping that it would be a little nose heavy, therefore I could lightnen the load by using a lipo receiver pack and fiberglass/carbon fiber landing gear with ultra light wheels.
Any balance information you can provide would be helpful.
