I have a Hobbico Superstar and have found that the metal that is used for those mounting straps is horribly soft and flexed/deformed with approximately 25lbs of torque. In addition, the eyelets for the bolts are not small enough and allow for too much play. I am in the process of replacing all the hardware up front (its all junk-too soft, besides the actuall mount). A little bit of flexability is desireable but using a softness of 1.5 (exaggerating) for an engine securing plate is just not sufficent in my mind.

Even if im just being over-cautious, at least I'll have peace of mind.
