I agree that they need to improve the composites for the arms, wing mount, wing and skids.
They're definitely too rigid for 'extreme bashing'.
I would argue that Corally are already competing with Arrma and Traxass. For a start, Corally rigs drive nicer than the Arrma alternatives and don't cost £4billion like the 100% plastic Traxass, politically incorrect offerings.

Corally over the years haven't really specialised in RTR's or bashers - they produced top tier racing kits and won world championships. They might be a couple of versions behind the Kraton, but Corally's progress has, arguably, been exponentially good.
I'd personally like to see Corally and Arrma romp home with all the success in the world.
That reminds me - I really 'need' to buy an Arrma EXB before I buy any more FPV flying machines.....
