Blade question

i have a 400 size heli looks like the blade are about 300mm.

at a LHS i found some blades that are 325mm.

is there any problems using a lil bit bigger blade

Art-Tech falcon 400 is my heli

Blade 400 325 mm blades are the ones i was looking at

Myself, I think they would just make the motor work a tiny bit harder to spin them, not sure tho...

I just got a set of "3D Plastic Blades" for my Belt-CP from US Hobby Supply, they are about and inch shorter than the stock blades and bowed kind like the HB SuperBlades... Gonna test them today... I also got a set of Carbon Fiber blades and a set of Align 335 Pro "Woodies" that are about an Inch "longer" than the stock blades...

The guy at US Hobbies says he's tested all these with the Belt-CP so I guess they will work fine...
