I have a Saito 56 powered SE ARF that I am happy with in all respects save one. The Sig supplied pushrods expand badly on hot days which plays havoc with the elevator and rudder trim. SoCal weather has been great this summer, but on many days the trim is all over the map... I would like to hear what others used to replace the stock pushrods. Thanks in advance.

I always use 4-40 steel rod instead of the supplied plastic or goldenrod ones. The 4-40 steel wont break as I have had both the expansion problem and the breakage problem with small ones. The weight is in significant and you can run the rods thru the outer tube of the plastic ones included in the kit. I have had the Sig SE and its a great flyer!

Glad to hear it will ok to use the steel rods. I was just going to ask this question myself. i'm in the final stages with my SE. I dont trust the solder on connections that can with and I dont want to worry about the heat expanding the nylon rods . I bought some 2-56 rods with some Sullivan Golden clevises. thanks, JT

Odd. Mine was assembled using all the stock hardware (except for the tailwheel assy) and I haven't noticed any significant trim issues, even after letting the plane sit in the sun for a couple of hours. I guess that the rods and the fuse in my model are expanding at similar rates.

If I have to build another one I'll use CF rods in the tail. Strong as steel and they weigh a lot less.
