Re: 2mm Carbon fibre rods alternative?

From the first pic only suggestion would be to clean up the front end and move the battery forward. Only concern would be adequate airflow for cooling.

What material is that fuse made of?

I just stuff everything inside for the photo. I tried moving the battery as far as possible but it still seems tail heavy. It is a 3d printed plane by eclipson, the material is PLA. Maybe I should print a CG balancer.

Re: 2mm Carbon fibre rods alternative?

Not sure what you are using or how you are balancing but yes, a good balancer helps.
What are you using for tail servos as some can be like lead and selecting by weight can be important. One of my larger aircraft has 3 in the tail (2 elevator and 1 rudder) and knowing that was critical; I went shopping for the lightest I could get with needed torque. Cost me more but in the end it saved me about 2 plus pounds in nose weight from what other guys were putting in to balance.
As a suggestion if you have to add weight ; I would try to add lead shot around the cowl nose ring to get it as far forward as possible.

This is what I use for balancing and found it to be the best of all my home made balancers over the name years . The marked "ruler" allows you to set the vertical stop tabs at the distance back that you want to balance and there are a ball bearings at the pivot point. Set your vertical stops ; adjust rear counterweights to balance. but the aircraft on the balancer and then you know were to add weight... front or back. Mine was an earlier version without the lower prop balancer added.

Mine has 2 servos in the tail and they are light weight. Idesigned a balancer myself and printed it using my 3d printer. After trying a lot I was able to make the plane stay leveled without falling on either sides. Can you please take a look at the photos and tell me if this looks balanced?
