Anyone have access to a GWS dragonfly and a walkera dragonfly #4?

I would just like to know if the rotor heads are interchangable... (the part you attach the blades to that pops off in a crash)

Anyone? please?

Do not mix to use other than GWS original blades or parts on GWS Dragonfly.

During 2005 RCX show, I flew with Steve Lo and Jarhead, I feel the timming even longer that that I said before!

With EM150 version GWS Dragonfly, some time arround 25 minites if the mechanic in properly set up.

However, after too many heavy landing or crashed damage, the friction will eat more current and reduce you flight duration.

Pls also read about this thread: http://www.rcgroups.com/forums/showthread.php?t=366222

Although many micro helicopter rotors looks similar, but performance quite different to each others.

Do not mix to use other than GWS original blades or parts. They may cause uncompetible problems!

They are completely different, bearing size and spacing, plus there is a web on the Walkera which would foul the GWS hub.

The gear ratio and motor design are totally different to each others!

I did test with Walkera and Jabo main rotors to be fit on GWS Dragonfly some time ago.

I had seen that the gear ratio and motor design are totally different to each others!

GWS current production of Dragonfly EM300H version which come with the main rotor from FEDA takes 3.6A at 260g lift. The GWS new rotor take only 3.1A.

When Max thrust FEDA rotor get 350g while take 6.4A. GWS new rotor max thrust 380g but takes only 5.9A.

But the test datas had shown they are not fit into GWS Dragonfly!

W brand takes 7.6A at max but only 290g lift thrust for GWS Dragonfly EM300H version.

J brand takes 7.4A at max but only 290g lift thrust for GWS Dragonfly EM300H version.

I just instruct GWS RD also should try to find a Walkera, E-Sky....others helicopter to see how a GWS main rotor balde will perform on them?
