RE: Extra (260) wing loading
1425 sq inches on your model - that is above 27% of scale of the EXTRA 260-
but many kits are interpretations of scale, not scale per se.
My own version of a Giles 202 model , was 1500 sq in and of a Dalotel was 1550 sq in both were 18 lbs aprox and both used ZDZ60 on 24x10 props (MenzS )running at 6400 rpm - both excellent performers . 22 lbs will give mor scale like performance --few very few full scale planes will hang on the prop - a local guy has a Pitts 12 which will -but not accelerate from that position.
somewhere around these numbers with the ZDZ60 will deliver a really good performance combo.
The clipped wing EDGE (a H9 kit and piped ZDZ80 J ) I call "Godzdzilla " really does have good power to weight - the static thrust is as noted but the best part is that reserve thrust at cruise speed is also instant . Net result is that any maneuver from any attitude can be accelerated . Just like a good foam/electric setup.
