I just checked my Avistar which came with medal rods and plastic guides and it
did not have any braces, except going through the fuse, after a few flts. I did add
a support at the bulkhead just after the servos.( it looks like 440??)
I also have both the throttle and steering medal rods on either side of my reciever
and have had no problems..
Not saying that you won't have any glitching or give of the rods, but only the way
mine is setup and working after 3 yrs.... I most likely have some give, but the throws
on her is not really all that much, and she hovers with the 46fx until gravity takes over..
