Hey guys/gals

I have 2 problems with my spad kit. First of all, the kit came with, what looks like cooper push rods (look at pic bellow) and I'm think they may flex/bend if I use them. What are your experiences with plain metal push rods without any tubing to prevent flexing?

First problem: Plane is nose heavy.

Second problem: all my servos setup are working fine except for my rudder servo, I beleive it's stalling (I hear a humming noise coming from the servo, even when it's in neutral). And I'm having a hard time gluing the push rod tubes to the pvc fuselage because of several factors.

I think I can fix both those problems by moving the rudder servor and the elevator servo (If I have to) from inside the fuselage ( right behind the landing gear) to outside bolted right in front of the stab. And use the cooper push rod that came with my kit. I don't think I'll be able to do that and use my plastic push rod tubes (Because I have no where to glue them if they servos are on top of the fuselage.) So I have no choice (I beleive) other then to use those metal push rods. But like I said earlier, I'm concerned with push rod flexing...

What do you guys think?

Sorry for the typos, I'm at work, it's busy and I had to make it quick :-)
