Diving at speed
 

I'm haveing a problem with a couple wings of mine. After I launch and the plane gets up to speed it starts to dive. Even with full up elevator I can't pull out. After I launch the plane usually points straight up while its slow. Im flying an avenger with my own wing on it, the airfoil is SD6060. I believe the problem is with aileron reflex. Do I have too much or not enough?

I just re-read your fact of straight up at launch. Did you balance at the COG and do some hand glides ?

If that levels the the plane with no power , it will fly to about 1/2 OK. Then you can move the motor angles around for Full power.

Scott, although I'm not team avenger I would lean toward too much reflex. On my own design, when it feels tail heavy I put in more reflex. I never have gotten to the no pull out dive though.

You've got a full flying tail, right? If not, I'd look at the tail incidence or look for warps in the tail surfaces.

Try moving the CG forward a bit and see if that helps.
