carbon blades? woodies? why?

[simon1]

Just thought as a newbie someone would clarify for me the significant differences in flight dynamics when using woodies and carbon blades?

Although there are obvious differences like the depth of the blade, like carbon blades look more aerodynamic and stronger? Do they really make so much of a difference on flying dynamics ?

and are the "cheaper" blades from hobbycity any good for 325mm carbons? Anyone had any of these?

hi

there are three different types of blades and hundreds of different makes and qualities as i found out the other weekend.

the wooden blades for the 450 size i don't think are worth bothereing with, you are probably better off getting some glass fiber ones, they are dearer than woodies but cheaper than carbons.

if you do run woodies keep your headspeed down try and find out what the maximum headspeed is for any blades you buy

if you get glass fiber ones you can run them at a higher headspeed than woodies but not as high as carbon.

if you buy carbon you can run even higher.

you will find that woodies are quite flexible.

glass fiber are stiffer.

carbon are more stiffer than glass fiber.

i have found that using different blades the heli does fly differently in that some blades are hard to track, some blades are balanced better, some blades are noisier than others.

as for flying i find that the higher the headspeed the more responsive and agile it is to fly, the lower the headspeed the lazier it becomes.

just be a bit careful with the quality of the blades i know for example you can get cheap glass fiber off ebay but i bought a batch of the red and white ones and they were brilliant and very strong they must have been by the way i chuck my 450 about, then i bought another batch of what i thought were the same blades and i put one set of them on and on the 3rd flight just on take off both blades came away at the roots and the heli crashed. it probably was a little unfair to the blades cause i run a very high headspeed.

like i have said try and find out from the retailer what is the maximum headspeed of the blade whatever material they are made of.

then again you could go for align/radix/torsion ect blades but you are looking at £25.00 plus, but if you are a beginner try and get some GF.

hope this helps

lf we`re talking about 325 size blade l run the stock TT wood blades flat out with no problem. Have tried Radix, Rotor Tech and Maniac carbon and they are all very good but the woodies will do the same job but not as smooth and about 4X the price.

tosh what HS are you running

tosh what HS are you running

Dont know, my tach dont go that high but its 100% straight across its pretty fast.

Crap vid on a cheap phone but it might give you an idea.

I use the 325 Pro Woodies and they have been great.

Cheap as well and I run flat line 90% with 12T pinion

[leckylee]

fair enough

[moyesboy]

I would stand well back from the heli if you are running woodies on 13T on 100% flat line.
The align pro woods are inpregnated with some sort of resin and seem to live at a higher head speed but they still say 2400rpm max on the packet. Maybe the TT woods Tosh is running are something similar?
The captain crash GLX 325 blades are good enough for chucking about hard and cost £19. The name brands are a bit stiffer and do fly a bit more accurately but the main effect is under heavy load there is less flutter noise and the head speed drops less.

With the head speed up near 3000 the 450 heli flies a lot nicer, particularly in wind and turbulence, and carbon blades are safest at theat speed.

[marktigere1]

The 325 Pro's are rated for 2600 I believe hence why I run 90% on a 12T pinion which gives me roughly 2400~2500 with the batts I run.

[leckylee]

2500 thats not fast enough

i suppose i do run 100% with a 13 tooth pinion with a 630xl motor and 2800 30c packs, mine is a little lively

[leckylee]

oh by the way does anyone know what the align carbons are rated at

[easypickingsere]

Dunno mate but if your on about them ones I gave ya Id slow it down....... Alot!

[simon1]

firstly thanks lee for explaining all of the in's and outs of the different blades, im only at the hovering stage at the min, with a bit of side on hovering. May purchase some of the glass fibre blades for if and when I progress from hovering stage.

Anyone recommend any good glass blades? for mini t?

cheers
