Pro 3D blade Review
Inexpensive
Fiberglass blades that peform well is a bonus for any helicopter flyer,
especially at the beginning when your getting used to it.
But Carbon Fiber blades will really show what this helicopter is
capable of as well as have less tracking inconsistances compared to
fiberglass. These blades are sold by Xheli, Hobbypartz as well as HeliDirect.
Both Heli Direct offer flat rate $4.95 shipping within the U.S.A for
spare parts. Blades at HeliDirect are slightly more expensive but
if your in a rush, they are on the east coast for local shipping to
that side of the country.
Carbon Fiber vs. Fiberglass:
I
have flown 205mm (250 heli), 325mm (450 heli) , 335mm (450 heli), 430mm
yellow/black (500 heli) both
Carbon Fiber as well as the Fiberglass. There is not much to tell the
difference between CF and FG for the 205mm blades but for the 325mm and
335mm the difference is noticable. Tracking can be an issue with
any fiberglass blade because they flex more. Plus Fiberglass is harder
to manufacture consistantly with all of that flex. Carbon Fiber
will have less tracking issues and will respond quicker in flight.
Fiberglass blades (like wood blades) can fludder if stressed in
high G manuevers like a high speed loop, quick flip or tic tocs. If you
are in a situation where you want to save $$ because you may crash
often becaus you are say a beginner or you are working on your inverted
low level hovering, you may want to think about the cheaper Fiberglass
blades. Fiberglass blades are good for sport flying as
well. Use CF for more roll rate and less tracking issues.
325mm vs. 335mm in a 450:
Most
450 helis can accept the 335mm blades. The 335mm blades will be a
little more stable, have less of a cyclic roll rate and will consume
more battery during flight. While flipping the helicopter, the
335mm blades will allow the helicopter to "float more" in the manuever
and have the tendancy to drop out of the sky slower than 325 or 315mm
blades. 335mm blades will also stress the cyclic servos more, so
if using 335mm blades, I recommend a seperate switching BEC and don't
use the built in linear BEC of the ESC.
