Hi
I have always used plain cc3d board for " acting crazy in the air "
In a thread titled
"Using a revo board in small acro/ racing quads"
I enquired if I was missing out by not using a revo.
Advice then was no.
Yeah , gps/ speed readout would be nice but really , I think Fpv (acro/racing) is so much fun , knowing 'how fast' doesn't seem to matter.
( have paced out a 100m run just to find a speed by timing the dvr vid. )
As for 'home arrow' , cute , but really , you're tooling about , crashing lots , so never really going far ( unless you enjoy a long walk ) - and most importantly , you've got a camera on the front and a screen / goggles - how can you not know the way back ?
Hope your 250 Fpv goes well.
