I started the process of excorcising whatever
demons possessed the ERazor 450 by stripping out the servos, removing the tail boom support struts, replacing the horizontal fin and the vertical fin, restabilizing the tail boom, and taking apart the rotor head and removing the broken main shaft halves. I found one set of one of the main blade grip bearings to be damaged, and replaced those. I am replacing the stock swash servos (which seem to be a variant of the Tower Pro SG90). I will also be taking the Hitec HSG 5084MG tail servo off the CopterX 250 and using it instead of the stock tail servo, which I suspect is the same as the stock swash servos. I have a replacement rotor head block coming since I think the washout guide pins are bent and may have contributed to the last crash. Some of the ball links are a bit stiff, and I will be addressing that as well. The swash assembly doesn't move as smooth as it should. I am confident they will move smoothly after this work is completed.
I am pretty sure that she is going to come out of this refit a very fine 450!
