Amp drawn : 46 - 49A

These motors worked better than what were on EB A-4 ones. But the Amp drawn might not be good news for your budget.

Hi Chen,

Thanks for the clarification. It's looking good.

The real -10 air-intake is quite small.

Since GWS J-10 model is an EDF powered, not a turbine. We need enough air-intake space to feed her POWER!

American always need more POWER!

Do you mean that gaping hole in the bottom of the fuse? When did that get there?
Perhaps with a smaller fan (69mm instead of 75mm) it might not be necessary. Need to know the intake dimensions to be sure.

Hi Jeff,

There's hole located at its belly. Just click at page 10 of the manual.

Hi Chen,

Yup saw that. I was just joking. It's actually not too noticeable once the hatch is installed. Would you happen to know the air intake area? It looks like a rectangular cross section and might be just enough for a fan that's a little smaller.

Jeff, both the air intake (about 80 x 40mm / 3.15 x 1.575")and the special hole are quite big, check up page 4 and 5. I'm afraid that you have to work more on the EDF hatch if you would like to install a smaller EDF, 69 mm one.

Don't make such modification.

One of the flyer in Taiwan had done such way with an expensive 70mm fan and motor, but quite disappointed....

Can we have a picture of the second J-10 up close, looks like a good paint scheme from the video.

Also, when is GWS USA going to have the NPS in stock?

Ouaouhhh!!! 500W with 3S!!!
I'd prefer less amps with more voltage (4S) because I haven't any lipo battery able to give 50A...

disappointing with the 70mm fan on J-10?
Why?

What pack, what motor did he used with the 70mm fan then?

This is one of the recommended 70mm fan power systems outthere
for either the GWS Scooter A-4 or
the GWS Chinese J-10 (Jian 10) Vigorous Dragon



Medusa 3400KV, HET fan 6904, 4S lipo that can
handle 50 amps continously. This system draws 45-46 amps
and output 1100+ grams of thrust (static).
Thunderpower Extreme V2 2200 4S would do this very well.

Would this be enough for you?
