Lucky it landing safty ! it is so diffcult ,the head rpm are only 1100 .But for 4 blades head are enough . because 4 piece blades , flying feeling samilar normal head 1600 rpm .But blades are too light .very sensitive in control .So we must usa a flyberless system .I will try again fix it with Mirco beast .So let waiting or fly again !

Hi Kin,

I've added some gyros to Real Flight's Jayhawk to simulate an FBL unit...
check it out here

I've added some notes in the description so you can make whatever adjustment you want to it.

Thankyou !

Yo kin, here is your blades in flight check it out.

Looks great.
What is the length of the TF blades,did you have to trim/cut to 600mm?

sidneyw,

No i just open the pack of 3 and install them. they are 600mm.

we have 600mm and 700 mm .both same material and flat bottom blades . the hovering pitch only need 3-4 drgee ! very save power !

Kin - Any word on the direct drive tail motors for your 700 size Hawks (Sea, Fire and BlackHawks)?

Cheers - Boyd

Kin, the three blades you sent me are 700mm. Can I cut them to 600mm?

I have the 450 Apache rotor blades , but for my recommend . the Apache is 4 blades head , if you use stock motor or you are not use a special strong motor , the baldes length for 4 piece rotor blades is 310-330mm is enough , if the blades are over 330 mm , the motor and your power set need upgrade , and down the head speed . i think 4x 360mm blades will very high load the power set. it get very hot . but the 450 size fuse for 4 blades 310-330mm is ok ! I am not sure the 360 mmblades will hit the tail blades or not , but in my personally concept . the extra length main rotor blades (especial 4-5 piece blades ) the head speed should down to 1500-1600rpm , but the normal length tail blades can not good force enough to push the tail .it must add the tail length 5-10 mm longer , , if the main blades 360 and than the tail blades add 10 mm more , Is it possible the fuse size enough ?? So i highly recommend 450 size 4-5 blade length 310-330mm and then extra add 5-10mm tail blades longer .http://www.smartmodel.com.hk/product...0&third_id=156

Kin,

The 360mm blades have plenty of room to fit.
Runs very well and cool with a Scorpion -10 on 4S.

Test Flight: 450 Size AH-64 Apache - Pilot: Kip Newby (4 min 33 sec)

Wing Wing T450 AH-64D.wmv (5 min 50 sec)

Heh, looking at my 'skating on thin ice' flight of the 3G powered AH64 brings back un-fond memories, lol. Glad to get a Vbar on that one . Even with a 22x15mm stator motor 4 360's work ok, given low enough gearing (15:1). Definately go bigger than 3S on the Apache (4 or 6S), that model needs a ton of ballast (or big battery) to balance, and that really makes it a porker.

Kin,

You guys made the Apache scale blades before there was a fuselage available.
We now know that those blades really are to short, for the Apache fuselage that is on the market.

The Apache needs 360mm!

In my honest opinion and experience using the 320mm scale blades, they are too short, look odd (too small) on the Apache, and don't provide enough lift and stability. The Apache is a heavy bird, and the 320's are not appropriate for the task.
