Terrible throttle bind.
 

I have terrible bind in my throttle pushrod. As you can see, I have to "bend" the pushrod too far to go into the pushrod connector.

Need advice. Do I put a bend in the pushrod? do I move the servo closer to the wall of the fusalage? If I do the latter, how would I hold the servo in place on the other end?

btw, no, I have not cut the pushrod to length yet.

BTW, this IS my first plane, its a Sig LT-40, and having a blast putting it together.

Thanks,

take a piece of regular wire and make a model of what the control rod needs to be to fit without binding. When you are satisfied with model template (no binding and good clearacnes) bend your control rod to match.

Your picture really dosent show the problem. Whitch servo are you using for the throttle? if you cut to move it just use some scrap and glue it in place to mount the servo.

or I can make sure the servo is going in the right direction *smacks forehead*

Once I reversed chan 3, all is well *sigh*

thanks for the input though

Dont smack too hard, we all make mistakes... LOL

That's very thick wire for a throttle pushrod. If you still think it binds too much, you can swap it for a cable setup, but that will require a soldering iron and a little practice. But they move much easier, especially if you have to make it curve at all. Looks to me like yours is relatively straight....

At least you caught your reversed servo before you tried to start your engine!

Heh heh...a reversed servo is nothing compared to the "brain farts" I've had.
Glad you got it going. The suggestion to use a cable is a good one. They are easier to route around fuel tanks, and such. And in the event of a nose in crash, it might save your throttle arm on the carb, and servo gears, at the very least.;)
