390mm blades on a 500????

[heliward0]

i have got a set of 390mm carbon blades,, i would like to fit them to my t-rex500 and remove the SAB blades so that WHEN i crash it will kill the ceepo blades not my best blades so my question is what would be the difference in fitting 425mm or the 390mm is it advisable to do or not bother??

any one???

try them it will have loads of power but may suffer stability and punch, it would be similar to a 90 rnning 710 or 680

I recon youll get loads of headspeed but as jason says it will lack punch.

should see increases in cyclic speed as well as there's less disc to rotate.
