In general, 2-blade props outperform 3 bladed.
Still, I fly my Zero with a Biela 22x12x3 bladed and have plenty of power with the Saito FG 90R3.
I like the scale look.

Finally, I added nose weight (lead shot) to the front lip of the cowl in a 3/4" clear vinyl hose. Felt this was the...

Hey,
I've only used the Keleo. First on my FG84 and now on the FG90. Stock exhaust should be fine. To me, it's more about the sound than power. As far as airflow, I have had no problems once I...

Same here. My flaps deploy in 2-3 seconds. No pitching.

You should be fine in the air. I'm getting around 6300 rpm in the air with a prop unload to around 6800. We generally run no higher than 6300 rpm. This is a bit faster than scale presentation....

I would check what is "behind the CG". That seems very heavy to me. My plane came out around 31lbs with a fully cockpit and pilot. Something not right there.
