Working on the Trex 700

 

I spent yesterday pulling the main rotor blade holders apart, lubing the bearings and putting it back together.  That is it laying on the instructions.  Today I pulled the main rotor drive gear apart and serviced the autorotation bearing.  When I got that back together I pulled the motor out and cleaned it up.  I spent some time online finding and ordering some upgrades and bearings I wanted to replace.  During my research I found out the motor sells for $329, which is more than I paid for the helicopter, boy was that a surprise.  It's maximum power rating of 3500 Watts which is way more than I will ever use.  I just did some checking and the speed control that came with it is $234!  I also got the right trailing edge of the Comet sanded down so, now I can put some fiberglass where the vertical fin mounts.  They didn't call for it in the instructions but that 1/16th inch balsa just doesn't look strong enough to me.  That building they were tearing down across the street is completely gone now.  There was a crew taking down the wood frame work today and Vera saw them head up the hill with two trailer loads.
