Boomerang1, You brought up temp related problems, I have a T/F mustang that uses the push/pull you described. I find that when it's cool I have to put up trim, when hot, down trim. I am using the stock 4-40 wire. I know what piano wire is. Are you replacing the stock stuff with piano wire?

Didn't even think about the differnt types of wire. What I meant was wire versus plastic pushrods.
I have a jet with very long wire pushrods of this type (about 4 feet long) & haven't noticed any big
trim changes. I just use the wire from the K&S stand at the LHS as it comes in long lengths.
What colour is your model? If it's olive drab or something it may be getting much hotter inside in the
sun than my white jet. - John.
