Some upgrade/custom parts are available for the 1/12 Corsair:
– fully printed tail (replacing the depron parts)
– “tool” to make a fully transparent canopy from a PET bottle with a heat gun
– dummy radial engine (for Turnigy 3530)
– reinforced battery holder with some air deflector towards the battery (and a bit better ESC cooling)
All things are up on Thingiverse, if you’re more interested.
